ABSTRACT
Background
Medical method of abortion – a combination of Mifepristone followed by
prostaglandin analogue such as Misoprostol has been used up to 9 completed weeks
since last menstrual period. Misoprostol is the prostaglandin of choice for most
settings since it is cheap and does not require refrigeration.
The availability of safe and effective medical methods for inducing abortion
remains limited at present. However, rapid development and ongoing research may
lead to their wider introduction in the near future.
Objectives
The aim of the present study is to compare the efficacy of Mifepristone
followed after 24 hours by Misoprostol with the standard protocol (Mifepristone
followed by Misoprostol after 48 hours).
Materials and methods
This prospective case control study was conducted in 120 patients up to 63
days period of gestation who was diagnosed with early pregnancy failure & suitable
for medical abortion from a period of November 2013-October 2015.
Subjects in study arm was given 200 mg oral Mifepristone followed by 800
mcg vaginal Misoprostol after 24 hours, whereas those in control arm was
given 200 mg oral Mifepristone followed by 800 mcg of vaginal Misoprostol
after 48 hours.
Women who did not have bleeding in the first 8 hrs following 800 mcg
Misoprostol were given subsequent 200 mcg of vaginal Misoprostol. Doses
x
were repeated at 4th hourly interval to a maximum Misoprostol dose of
1200mcg.
Sequential allocation was done in the ratio of 1:1.
Statistical analysis
It was done by using Student t test & chi-square test. Descriptive and
inferential statistical analysis has been carried out in the present study.
Summary of results
Out of 135 patients screened 15 patients were excluded as per exclusion
criteria and 120 patients were taken for study. Mean induction to abortion interval in
study group was in the range of 5-6 hrs versus 6-7 hrs in control group with P value of
0.772 .The success rate in study group versus control group is 78.3 % versus 81.6%
with P value of 0.29 .11/58 patients required curettage in study group compared to
6/55 in control group.Side effect profile between 24 vs 48 hour regimen was
statistically insignificant.
Conclusion
Vaginal Misoprostol can be safely administered 24 hours following
Mifepristone compared to 48 hours regimen with equal efficacy.

INTRODUCTION
Medical abortion is a safe, effective and non invasive alternative for early
pregnancy termination. It holds great promise to access to safe abortion practices in
developing countries like India. Drug control general of India approved 600 mg of
Mifepristone coupled with 400 mcg of Misoprostol for early pregnancy termination
up to 49 days period of gestation[1-4].
25-50% of pregnancies encounter spontaneous pregnancy loss which usually
occurs up to 13 weeks of gestation.This spontaneous first trimester pregnancy loss can
be described by various non standardized terminologies such as early pregnancy
failure, blighted ovum, anembryonic gestation and missed abortion which are
confusing but still commonly used terms. The total rate of pregnancy loss after
implantation, including clinically recognized spontaneous abortions is 31 percent.[5]
Sonographic diagnostic criteria for early pregnancy failure[6]
Crown-rump length (CRL) of ≥7 mm and no heartbeat on a transvaginal scan,
Mean sac diameter (MSD) of ≥β5 mm and no embryo on a transvaginal scan,
Absence of embryo with heartbeat ≥β weeks after a scan that showed a
gestational sac without a yolk sac,
Absence of embryo with heartbeat ≥11 days after a scan that showed a
gestational sac with a yolk sac.
Non invasive management modalities for early pregnancy termination.
The success rate of expectant management which is clearly an option for
embryonic death or anembryonic gestation is influenced by various factors such as
2
unpredictable expulsion, uncertainty, anxiety resulting from pregnancy loss, often
makes expectant management less appealing to patients[7, 8]
Characteristics of Medical management [9]
Medical management with Misoprostol for early pregnancy failure appears to
offer more prompt evacuation and has become an increasingly popular alternative
with the following features,
Avoids invasive procedure and anesthesia.
Requires two or more visits.
Takes days to weeks to complete the process.
Available during early pregnancy with high success rate (approx-95%).
Moderate amount of bleeding which rarely becomes heavy.
Requires follow-up to ensure completion of abortion.
Requires patient participation throughout a multiple-step process.
WHO recommendation for medical methods of abortion[10]
“The WHO multinational trial with respect to side effects and acceptability of
medical methods have found that 85% of participants had successful outcome for the
procedure. Significantly higher acceptability was found among parous women
(compared to nulliparous women).
In 2003, World Health Organization (WHO) recommended that oral/vaginal
Misoprostol should be administered 36–48 hours after oral Mifepristone.However
based on the studies conducted by Singh et al and Schaff et al, it has been proved
3
that the interval of 48 hours can be safely reduced to even 8 hours without
compromising safety and efficacy [11]
.
In our study interval of 24 hours has been chosen based on the
pharmacokinetics of Mifepristone, which exerts its response in the uterus by blocking
the action of progesterone . It has also been reported that 40% of patients started to
bleed prior to Misoprostol administration, indicating that the abortion process has
already started[12].
Thus when the process of abortion starts even before administration of
Misoprostol, the rationale behind waiting for 48 hours has to be questioned and this
concept forms the baseline of our study.

AIMS AND OBJECTIVES OF STUDY
The aim of the present study is to compare the efficacy of Mifepristone
followed by Misoprostol after 24 hours with the standard protocol
(Mifepristone followed by Misoprostol after 48 hours).
To evaluate whether 24 hour interval regimen will be an alternative to
standard 48 hour regimen without compromising its safety.

Introduction
Pregnancy is a significant event in woman’s life. Emotional attachment to the
Pregnancy and developing baby begins early in first trimester. Experiencing a first
trimester loss is a difficult and vulnerable time for most of the women. When it
occurs, the grief can be as profound as for any perinatal or other major loss [13, 14]
.
6
Spontaneous abortion (a pregnancy that ends spontaneously before the fetus has
reached a viable gestational age) is among the most common complications of
pregnancy.
Approximately 12–15% of recognized pregnancies and 17–22% of all pregnancies
ends in spontaneous abortion [13, 14]
.
Etiology
There is no clear cut etiology for first trimester pregnancy loss, instead we
have multiple risk factors which increases the likelihood of pregnancy loss.[15]
Table 1 : Possible risk factors for early pregnancy failure [16,17]
Maternal age >35 years.
Body mass index < 20 kg/m2, irrespective of age.
Increased serum cortisol levels.
Increased stress in life.
Low serum progesterone levels (< 12 ng/ml) prior to 7 wks of gestation.
Non-steroidal anti-inflammatory drug (NSAID) use.
Poor glycemic control.
Obesity.
Thyroid dysfunction.
Acute infections (Listeria, toxoplasmosis, parvovirus B19, rubella, herpes).
Hypercoagulable states.
Smoking.

TYPES OF EARLY PREGNANCY LOSS [13]
Spontaneous abortion
A pregnancy that ends spontaneously before the fetus has reached a period
of viability. The World Health Organization defines it as expulsion or extraction of
an embryo or fetus weighing 500 g (typically corresponds to a gestational age of 20
weeks) [13]
.
Threatened abortion
Bleeding through the cervical os with suprapubic pain during the first half of
pregnancy warrants threatened abortion in a patient. On examination, the uterine size
corresponds to gestational age, cervix is long and closed and fetal cardiac activity will
be detectable if the gestation is sufficiently advanced [13]
.
Inevitable abortion
Inevitable abortion is the pending abortion where the patient presents with
increased bleeding, intensely painful uterine cramps and dilated cervix. The products
of conception can often be felt or visualized through the internal cervical os[13]
.
Incomplete abortion
Incomplete abortion is the abortion with significant retained products of
conception which commonly occurs after 12 weeks of gestation. On examination, the
cervical os is open, products may be observed in the vagina/ cervix, and uterus is
smaller than expected for gestational age with painful cramps. There can be variable
amount of bleeding and it can be severe enough to cause hypovolemic shock [13]
.
8
Complete abortion
Complete abortion usually occurs before 12 weeks of gestation where the
entire contents of uterus are expelled. More than one-third of all cases are complete
abortions.On examination uterus will be small, well contracted with a closed cervix;
slight vaginal bleeding and mild cramping can be present [13]
.
Missed abortion
Refers to in utero death of the embryo or fetus prior to the 20th
week of
gestation, with prolonged retention of pregnancy for about 4 to 8 weeks. Vaginal
bleeding may occur and cervix is usually closed [13]
.
Septic abortion
Septic abortion accompanies fever, chills, malaise, abdominal pain, vaginal
bleeding, and frequently purulent discharge. Physical examination reveals
tachycardia, tachypnea, lower abdominal tenderness, and a tender uterus with dilated
cervix.Commonest organism causing infections are Staphylococcus aureus, Gram-
negative bacilli, or some Gram-positive cocci. Mixed infections (anaerobic organisms
and fungi) has also been encountered. Spreading of infection can lead to salphingitis,
generalized peritonitis, and septicemia [13]
.
9
PATHOLOGY OF EARLY PREGNANCY FAILURE [16, 17]
Maternal blood does not circulate within the placenta until about 9 weeks of
gestation. Prior to this time, trophoblastic cells serve to“plug” maternal spiral arteries,
preventing flow to these arteries and into the intervillous space until the villi mature
and begin to grow into the myometrium.
Minimal exposure to the high levels of oxygen in maternal blood during the
first trimester of human pregnancy is critical as the fetus and the placental villi are
exquisitely sensitive to oxidative stress. If exposed prematurely, pregnancy loss may
result. Thus histopathologic studies of fetal and placental tissue after pregnancy loss
shows premature intervillous blood flow.
Although Doppler flow may not be sensitive enough for assessing pregnancy
outcome, it has shown promise in predicting success of expectant management in
incomplete pregnancy loss. Presence of blood flow in the intervillous space using
Colour Doppler during evaluation of a threatened abortion increases the chance for
subsequent complete pregnancy loss with expectant management by fourfold.
10
Detection of First Trimester Loss
Presence of cardiac activity after 5 weeks and length of embryo of 2 mm declines the
risk of spontaneous loss to 3-6% [18]
.
Abnormal Sonographic findings suggestive of pregnancy loss prior to detection
of a heartbeat [18-20].
Gestational sac smaller than expected for dates.
An abnormal appearing yolk sac that is large, irregular, free floating, or calcified
should be followed by repeat ultrasonographic evaluation.
Although reproducibility is poor, placental abnormalities such as increased
echogenicity, increased thickness of trophoblast, or subchorionic hemorrhage
have been hypothesized as potential markers for subsequent pregnancy loss [18-20]
.
Figure 1 : Subchorionic hemorrhage [13]
11
Presence of subchorionic hemorrhage in first trimester with vaginal bleeding
raises the concern and anxiety of patients. But the timing of the bleeding has the most
important prognostic implications.
< 6 weeks - No increase in adverse pregnancy outcome [18-20].
>7weeks -10% chance of early pregnancy loss or later
pregnancy complications[18-20].

Gestational age.

Management of first trimester pregnancy loss [13]
There are three forms of management [13]

Mifepristone (RU 486)[21-26]
History : Roussel Uclaf (RU) was the French pharmaceutical company which first
developed RU486 in the early 1980s. The 486 designation is the shortened version of
compound name “γ8486” [21, 22].

Figure 4 : Mifepristone approval worldwide - 2014
Mechanism of action[21-23]
Mifepristone (RU-486), a derivative of norethindrone, binds to progesterone
receptors with an affinity greater than progesterone but does not activate the receptor,
thereby acting as an antiprogestin.
Progesterone induces hyperpolarization of the cell membrane, which makes
the myocytes less sensitive to electrical stimulation thereby inhibits contractility of
uterus. It also causes inhibition of gap junction formation, which counteracts
coordinated uterine contractions. This actions of progesterone was antagonized by
Mifepristone which causes
Necrotisation of the decidua,
Softening of the cervix,
Increases both uterine contractility and prostaglandin sensitivity.
14
Figure 5 : Mechanism of action of RU486
Human studies have suggested that uterine contractility does not increase until
24–36 hours after Mifepristone administration. At this point, the myometrium is five
times more sensitive to the stimulatory effects of exogenous prostaglandins [23, 24]
.
Additional properties
Mifepristone also posseses anti-glucocorticoid action and weak anti-
androgenic activity.It is devoid of estrogenic properties [23, 24].
16
Table 2: Effect of Mifepristone on various phases of Menstrual cycle[23-26]
In normally menstruating women, the effect of Mifepristone depends on the
timing of administration.
Phase of menstrual cycle
Effect of Mifepristone
First half of luteal phase
Independent of luteolysis menstrual induction occurs
During mid- luteal phase
Produces bleeding within a few days
During late luteal phase
Bleeding will be noticed within 1 to 3 days, reduces the
length of luteal phase of the present cycle and lengthening
of the subsequent follicular phase.
Day1, 2, 3 of the menstrual
cycle
No effect on cycle length
Late follicular phase
Prevents LH surge thereby prolongs the follicular phase
and new surge will be delayed by next 15 days.
17
Pharmacokinetics[24, 25, 26]
Absolute bioavailability of Mifepristone following intake of 200 mg was 69%.
It follows a non-linear pharmacokinetics and its volume of distribution and clearance
are inversely proportional to concentration of α1-acid glycoprotein (AAG).Volume of
distribution is also time as well as dose-dependent .Peak levels will be attained in the
serum 1-3 hours following its intake.
Mifepristone is about 98% plasma protein bound with high affinity to α1-acid
glycoprotein. It crosses the placenta with the maternal/fetal ratio of 9.1 and 17.1
respectively.
Mifepristone is metabolized in liver by means of successive demethylations
and by hydroxylation. 10% of the drug will be eliminated in the urine and 90% in the
faeces.
Tolerability[24, 25, 26 ]
Being a well tolerated drug Mifepristone causes uterine bleeding which
generally lasts for maximum 12 days.The sort of bleeding will be similar to that of
menstrual bleeding .It rarely requires curettage and blood transfusion and usually can
be controlled with hemostatic drugs.
18
80% of patients develops pain following 4th hourly administration of prostaglandin
and it can be well managed with non-narcotic analgesia. Whereas 20% of the patient
still requires parenteral narcotic analgesia.
Adverse Effects[26]
Most common adverse effects which patients encounter are
Abdominal pain
Fever
Nausea
Vomiting
Anorexia
Drug interactions with Mifepristone[25, 26]
Specific drug or food interactions have not been proved.
Based on the drug metabolism by CytochromeP-34A, Ketoconazole,
Erythromycin inhibits its metabolism as well as increases serum concentration.
Anticonvulsants such as Phenytoin, Phenobarbitone, Carbamazepine,
Rifampicin, Dexamethasone lowers the serum concentration of Mifepristone.

Historical review and Biochemistry of Prostaglandins
Prostaglandins are a group of potent hormone like compounds composed of essential
fatty acids and found in all mammalian tissues, especially human semen.
Prostaglandins stimulate the muscles of the uterus and affects the blood vessels [27].
Table 3 : Milestones in the discovery of prostaglandins [27-30]
1930 A 20 carbon polyunsaturated essential fatty acid extracted from human
semen was found to contract the isolated uterine muscle.
1935 Von Euler coined the term“ Prostaglandins”
1936 Pharmacological effects of Prostaglandins was firmly established
1962 Bergstrom and Syovall elucidated the chemical structure.
1966 Sulthan Karim used prostaglandins for induction of labour and abortion.
1968 Plexaura Homamalla, a kind of coral found in florida and a variety of
Georgian coral was found to be a rich source of Prostaglandins.
1973 Searle developed Misoprostol for the treatment of Gastric ulcer
1979 Keisse discovered high levels of endogenous prostaglandins during labour
1982 The Nobel Prize in Physiology / Medicine was awarded jointly to Sune K.
Bergström, Bengt I. Samuelsson and John R. Vane "for their discoveries
concerning prostaglandins and related biologically active substances".
1985 US-FDA approved prostaglandins for the treatment of peptic ulcer.
2000 Patrick S et al concluded that there is no effect of vaginal PH over the action
of Prostaglandins for cervical ripening.
2012 Prostaglandins produced by innate immune cells may have an important role
in controlling HIV replication, specifically in the CNS.
20
Biochemistry of prostaglandins [31-34]
“Prostaglandins are composed of a Cyclopentanone nucleus with two side chains.
Primary prostaglandins contain a 15 hydroxyl group with a 13, 14 trans double bond.
Categories of prostaglandins
Currently three classes of prostaglandins are recognized and these are
categorized on the basis of
Number of double bonds present within the prostaglandin molecule
Fatty acid from which they are derived.
Prostaglandins of 1 series have single double bond and are derived from
dihomo linolenic acid, those of 2 series have two double bonds and are derived from
arachidonic acid, and those of the 3 series have three double bonds and are derived
from eicosapentaenoic acid.
Categorisation of the thromboxanes and leukotrienes are also done depending
on the number of double bonds in the molecule. Each type of prostaglandin is
allocated a group letter (e.g., A, B, C, D, E, F, G, H), depending on the functional
substitutions in the cyclopentanone nucleus.
For example, in prostaglandin F (PGF), F indicates Prostaglandin has two
hydroxyl groups in the cyclopentanone ring (F series) ,2 indicates presence of
two double bonds ,α indicates hydroxyl grouping at carbon 9 is in the α
configuration.
21
Prostaglandin Synthetase Pathway [31-34]
The incorporation of molecular oxygen into arachidonic acid and fatty acids
results in the formation of unstable intermediate molecules. This action is mediated by
Prostaglandin synthetase (cyclooxygenase moiety) and this intermediate molecules
are referred as prostaglandin endoperoxides ( PGG and PGH).
Two separate genes encodes two PGH synthases : one is a constitutive enzyme
found virtually in all tissues, termed as PGH synthase 1 or Cyclo-oxygenase 1.The
second enzyme called PGH synthase 2 or COX 2 Which is inducible and is markedly
upregulated during cellular differentiation by cytokines or hormones.
26
PHARMACOLOGY OF MISOPROSTOL
History [35]
PGE1 analogue Misoprostol (15-deoxy-16-hydroxy-16-methyl PGE1),
developed in 1973 by Searle for the treatment and prevention of gastric ulcer. First
marketing authorization was given in 1985 and now more than 80 countries approved
its use, mostly under the brand name of Cytotec.

Available in market as 200 mcg, 100 mcg, 50 mcg and even 25 mcg [35]
Licensed indication for Misoprostol includes[35]
Gastric ulcer
Vaginal suppository for induction of labour
28
Misoprostol wears the crown among prostaglandin analogues in the market
due to the following advantages over other prostaglandins:
The licensed doses used for abortion has limited effect on the bronchi or
blood vessels.
Remains stable at room temperature, thus can be stored for many years.
Available for oral, vaginal, sublingual or rectal administration.
Cost-effective [35]
.
Mechanism of action / Uses [35, 36]
Enhances the gastric mucosal defence mechanism and helps in the healing as
well as prevention of gastric ulcer, especially NSAID induced gastric ulcer
and thus exerts its cytoprotective action.
Used for treatment of missed and incomplete miscarriages.
Helps in induction of abortion and cervical preparation before uterine
instrumentation as it encourages collagen disintegration and dissolution.
Used in late pregnancy for induction of labour and prophylaxis for the
treatment of postpartum hemorrhage through its uterotonic action.

Pharmacokinetics [35-37]
Table 4: Absorption kinetics of Misoprostol.
Absorption[35-37]
Rapid as well as complete absorption following oral intake.
The rate of absorption is reduced by food, whereas the extent of absorption is
food independent.
Associated antacid use reduces the total bioavailability.
Vaginal administration causes regular uterine contractions in contrast to oral
route where the chances of tonic contractions are more.
Peak plasma levels are obtained in 12 minutes whereas terminal half life is 20-
40 mins

Table 5: Metabolism and Excretion of Misoprostol.
Metabolism and Excretion [35-37]
Misoprostol is converted in to its pharmacologically active metabolite,
Misoprostol free acid by liver de-esterification enzymes.
It is free of drug interactions and it does not induce the hepatic Cytochrome P-
450 enzyme system.
Further oxidation of Misoprostol occurs in liver.
Mainly excreted in urine.
Misoprostol free acid is known to get excreted in breast milk.

Vaginal 20 ms 4 hrs
Rectal 100ms 4 hrs

Pharmacokinetics in breast milk [38-40]
Following oral administration Misoprostol free acid is found in breast milk
within 30 minutes.
Peak concentration in breast milk will be attained in 1 hour, whereas this peak
concentration level is found to be less than maternal plasma level.
32
Misoprostol free acid level found in breast milk will be undetectable 4-5 hrs
following feeding.
Side effects[40-43]
Abdominal pain, fever, shivering, nausea, vomiting and diarrhea are the common
adverse effects which are dose-dependent and self limiting.Very high doses of
Misoprostol along with Trifluoperazine has been reported to cause rhabdomyolysis,
hyperthermia, hypoxemia.
Teratogenicity[43-45]
Congenital facial palsy (Moebius syndrome) has been reported in the fetus of women
who took high dose Misoprostol in first trimester.Transverse limb defects,
arthrogryposis, hydrocephalus have been documented in some studies as rare
teratogenic effects.
Contraindications for medical management with Misoprostol[45-47]
HB < 10 gm/dl,
Previous cesarean section,
Previous Myomectomy,
Uterine perforation,
Cardiac anomaly,
Bleeding disorders,
Anti‐coagulation therapy,
Steroid treatment,
Renal disease.

Mifepristone - Misoprostol interval regimen.
The regimen approved by United states Food and Drug administration for
medical abortion up to 49 days is 600 mg of oral Mifepristone followed by 400 mcg
of vaginal Misoprostol 48 hours later with a success rate of 92%.This 36-48 hours is
recommended based on the fact that Mifepristone increases the sensitivity of
myometrium to prostaglandins which starts within 24 hours and it increases till 36-48
hrs. Compared with this regimen alternative evidence based regimens such as 200 mg
of oral Mifepristone followed by 800 mcg of vaginal Misoprostol 24 hours later
shows a success rate of 95-99% up to 63 days of gestation.24 hour regimen has
proved to be more effective regimen which needs lesser time for expulsion with fewer
side effects, low costs and more convenient [46, 47]
.
A Multicentre, randomized, control trial ( i.e) Comparison of Misoprostol 6
to 8 hours versus 24 hours after Mifepristone for abortion by Crenin et al reported the
overall success rate was 96% ( CI 94–97) in the 6-8 hrs interval group, compared to
98% (CI 97–99) in the 24 hrs interval group with(p= 0.005).Regarding side effects,
women in the short interval group experienced significantly lesser side effects than
those in the standard interval group. Assessment of pain and amount of bleeding were
similar in both the groups. About 90% of women in each group considered the
regimen they had received to be acceptable.Thus crenin concluded that 6-8 hrs
interval between Mifepristone and Misoprostol was equally efficacious alternative to
24 hour regimen with significantly less side effects and more acceptability[48].
34
A Recent prospective randomized control study done by Chaudhri P et al in
2014 in which he compared 24 hours versus 48 hours interval between Mifepristone
and Misoprostol for termination of pregnancy in 98 healthy women reported the
success rate of 95% in 24 hour group and 93.6% in 48 hour group with the p value of
0.38.The mean induction to abortion interval was (8.6±4.1hours in 24 hr group versus
8.7±γ.9hours; P=0.γ7 in 48 hr group). He reported longer induction to abortion
interval in nulliparous women in both the groups.He concluded that 24 hour interval
between Mifepristone and Misoprostol is equally efficacious to standard FDA
approved 48 hrs regimen for termination of pregnancy [49]
.
An open randomized trial done by Maarit mentula et al in 2011 which
included 227 women undergoing medical termination where oral Mifepristone (200
mg) was followed by vaginal Misoprostol (400 mcg) after one day versus two
days.He reported a longer induction to abortion interval of 8.5 hours (in 24 hours
group)versus 7.2 hours(in 48 hour group) with P value of 0.038.He reported 1 hr
longer induction abortion interval in 24 hour group.The rate of surgical evacuation
was higher in the 2-day group i.e., 37% in 48 hour group versus 25% in one day group
with 95% confidence interval.Finally Maarit Mentula et el concluded as “Both one-
and two-day dosing intervals seem to be suitable for medical termination of
pregnancy.However, evaluated on the basis of surgical evacuation, the one-day
interval could be supported as an option” [50].
A study conducted by Crenin et al in 2007 which includes 1128 women with
gestational age up to 63 days were given Mifepristone and vaginal Misoprostol
together versus 24 hour later showed that complete abortion rate did not differ greatly
35
among the two treatment groups (group1–Mifepristone and vaginal administration of
Misoprostol done together had complete abortion rate of 95.1%, CI 93-96.8%; group
2 (24 hrs later), 96.9% success rate with CI 95.1-98.2% and P value of.003) [51]
.
Chen Ay et al in their study included 1080 women up to 63 days period of
gestation. Women were given 200 mg oral Mifepristone followed by 800 mcg vaginal
Misoprostol administered on one or two dosing schedules. 6-8 hours was assigned as
group 1 whereas 24 hours was assigned as group 2.Participants recorded daily
bleeding in a diary over a period of 5 weeks. He concluded that total duration of
bleeding ranged from 1 to 54 days (median 7 days), and spotting ranged from 1 to 80
days(median 56 days) in both groups. Neither duration of bleeding nor duration of
spotting were related to the interval between Mifepristone and Misoprostol. Increased
gestational age was correlated with longer duration of bleeding (p=.007) and spotting
(p<.0001), and nulliparity was associated with longer bleeding time (p=0.003) [52]
.
A prospective randomized trial evaluated by Schaff et al who studied the
outcomes of 2, 255 pregnant women with gestation age up to 56 days of gestation
undergoing medical abortion using the following regimen: 200 mg oral Mifepristone
followed by 800 mcg vaginal Misoprostol self administered, 24 hours, 48 hours and
72 hours later. A second dose of Misoprostol was administered if the abortion was
not complete following 8 days after Mifepristone.He concluded that “complete
abortion rates were 98% (CI: 97-99%) for Misoprostol after 1 day, 98% (CI: 97-
99%) for those using Misprostol after 2 days, and 96% (CI: 95-97%) among those
using Misoprostol after 3 days. Abdominal cramps and nausea were the most
36
common side effects reported across all groups and over 90% of women found the
procedure to be acceptable” [53].
A study done by Ashok et al regarding the effect of Mifepristone on cervical
ripening, dilatation and softening has found that the priming effect of Mifepristone
after 48 hours is significantly more pronounced than after 24 h [54].
Heikinheimo et al in their study showed that women who received
Mifepristone 24 hour before the procedure had a significantly lower baseline cervical
dilatation (7.5 mm vs. 8.3 mm; p value of.05) and required greater mechanical force
to dilate the cervix than women who received Mifepristone 48 hour before the
procedure. Similarly, the mean interval from induction to expulsion was significantly
shorter when prostaglandins was initiated 48 h (6:20 h) after Mifepristone compared
to 24 hour (7:25 h).This is in contrast to the findings of other studies documented
prior[55]
.
Review studies on Medical methods of abortion.
The review study conducted by Weeks et al which reviews many randomized
control trial suggests that vaginal Misoprostol when compared with placebo speeds
up the miscarriage process (complete or incomplete), it also reduces the need for
curettage. No significant side effects have been documented in this study. Lower
doses of Misoprostol have found to be inferior in efficacy to single dose of 800 mcg
Misoprostol which proves more effective [56]
.
37
Elrafey et al in his partially randomized study compared surgical and medical
evacuation and found that 20% of women expressed a strong preference for medical
management. The main reasons given for their choice were ‘avoidance of anaesthesia’
and the feeling of being ‘more in control’ [57].
Hinshaw et al documented higher success rate of up to 96% associated with
high-dose vaginal Misoprostol for incomplete miscarriage [58]
.
Two randomized control trial done by Tang, Ngoc NT suggested that the oral,
sublingual and vaginal routes of Misoprostol are equally effective. In one study done
by Tang et al, missed miscarriages managed with either oral or sublingual
Misoprostol showed success rates of 87.5% (95%CI 74–95%) in both groups. This
randomized controlled trial by Ngoc et al where women, managed with either oral or
vaginal Misoprostol, also showed no significant difference in successful outcome
(oral 89% versus vaginal 92.9%)[59, 60]
.
The randomised trial done by Demetroulis and Trinderet al showed no
statistical difference in efficacy between surgical and medical evacuation for
incomplete miscarriage and for early fetal demise at gestations less than 71 days or
sac diameter less than 24mm. Patient acceptability for both methods was equal.
There was a reduction in clinical pelvic infection after medical evacuation (7.1 versus
13.2%, P < 0.001).With increasing gestation and sac size, acceptability of medical
methods fell to 85% [61, 62]
.
38
Studies done by Nelison, Wieringaet al concentrating on variety of doses,
regimens and routes of administration have found that lower doses and oral
administration are less effective, and greater side effects have been associated with
sublingual administration. Thus the ongoing studies are still inconclusive regarding
the optimal doses and routes of administration[63, 64].
Marwan Odeh et al reported that success rate of medical treatment for missed
abortion is highly varying, ranging from 13% to 94%.He also reported that this
variance is due to the fact that success rate in medical management is largely
influenced by many factors such as lack of standard parameters to predict the
success, difference in the regimens used, and due to different definitions for
successful outcome [65, 66]
.
He also concluded that there is no correlation between gestational sac volume
and the success rate of medical treatment for early pregnancy failure, while the factors
such as previous term pregnancy, higher number of previous pregnancies and a higher
blood hCG level adversely affect the success rate of medical treatment for early
pregnancy failure.The study also suggests this factors should be explained to the
patient during pre treatment counseling only [65, 66]
.
39
Figure 15 : Three-dimensional ultrasound image showing measurement of the
gestational sac volume in an 8 week missed abortion [66]
The American College of Obstetricians and Gynecologists recommends
800μg vaginal or 600μg sublingual Misoprostol for missed abortions; sublingual
administration can be repeated every 3 hours for two additional doses. The reported
success rate for vaginal administration of Misoprostol is up to 97%. More prolonged
waiting periods or repeated dosing leads to higher success rates [67, 68].
40
Study done by Ashok et al to evaluate the efficacy of 200 mg Mifepristone
followed 36-48 hours later by 800 mcg vaginal Misoprostol for termination of
pregnancies up to 63 days period of gestation. The complete abortion rate was
97.5%. Two percent aborted following Mifepristone administration alone. The
median induction abortion interval observed was 4.15 hours [69]

METHODOLOGY
SOURCE OF DATA
We conducted a Prospective case-control study in the Department of
Obstetrics and Gynaecology, Adichunchanagiri institute of medical sciences,
B.G.Nagara from the period November 2013 to October 2015.We included all
pregnant women with gestational age of less than 9 weeks diagnosed with intrauterine
pregnancy failure as confirmed by ultrasonogram and undergoing medical abortion
and who are willing for follow up. Sample size was 120 ( among 135 patients
screened, 120 fulfilled the inclusion criteria- 60 in study group and 60 in control
group).Study group includes women who were given Vaginal Misoprostol 24 hours
following Mifepristone whereas 48 hour interval between Mifepristone and
Misoprostol stands as control group.
Exclusion criteria
1. Women in whom ectopic gestation is suspected (even clinically).
2. Women who are not willing for follow up protocols.
3. Breast feeding mothers.
4. Women with haemoglobin of lessthan 10 gm/dl.
5. Women with previous cervical surgery - scarred cervix.
6. Women with previous scar in the uterus.
7. Women with asthma/glaucoma/adrenal insufficiency/poorly controlled
seizures/cardiovascular disease/coagulopathy.
8. Women on systemic corticosteroid therapy/anticoagulant therapy.
9. Pregnancy with IUCD in situ.
42
PROCEDURE:
Informed written consent of the patient was taken after explaining the
complete procedure in patients own understandable language.
PREPARATION OF THE PATIENT
Complete history was taken and thorough general and systemic examination
was carried out.
Speculum and vaginal examination was done in all the patients.
Patients were counselled about the method they were allocated and side effects
of the drug.
Sequential allocation was done in the ratio of 1:1.
Subjects in study arm was given 200 mg oral Mifepristone followed by 800
mcg vaginal Misoprostol after 24 hours, where as those in control arm was
given 200 mg oral Mifepristone followed by 800 mcg of vaginal Misoprostol
after 48 hours.
Women who did not have bleeding in the first 8 hours following 800 mcg
Misoprostol were given subsequent 200 mcg of vaginal Misoprostol.Doses
were repeated at 4th
hourly interval to a maximum Misoprostol dose of
1200mcg.
All subjects were informed about the signs and symptoms of expulsion and
need for follow-up.
All women was given a 24 hour contact telephone number for any post
treatment advice.
43
They were asked to come for follow-up after 14 days when transvaginal
ultrasound (TVS) was performed to confirm whether expulsion process was
complete.
If retained products of conception was documented on check scan, depending
on the amount of retained products of conception and amount of bleeding,
Curettage was performed and products sent for histopathological
examination.

DISCUSSION
Medical abortion has been a revolution in obstetrics practice, for the ease and
safety it provides to the clinician and the patient, as well as its role in preventing
deaths due to unsafe abortions in developing countries like India [70]
.
The challenge of medical abortion, therefore, is to find the best balance
between Mifepristone and Misoprostol (i.e) to find the optimal dose, route of
administration, interval between the two drugs, and knowledge on side effect profile
so that highest level of efficacy and good tolerance will be maintained[71, 72, 73]
.
Though several studies focusing on shorter interval between Mifepristone and
Misoprostol are available in the literature, stratification of 24 hour versus 48 hour
regimen and efficacy in both the groups in early pregnancy has not been researched in
detail.
Studies done by Shi Ye et al and Swahn et al showed that Mifepristone dosage
between 100 mg and 800 mg attains a constant level in serum, and the serum levels
are less variable, based on this fact 200 mg of Mifepristone was chosen for this
study[74, 75]
.
Rationale behind vaginal administration of Misoprostol in this study is due to
its higher success rate of 95% compared with 87% success rate with oral Misoprostol,
as well as due to its slow rise and sustained action for a long period[70]
.
63
Half of the women who received Misoprostol after 48 hours started having
bleeding as early as 3 hours and they continued to bleed until they expel, thus
reducing the time interval results in lesser time needed for expulsion, lesser duration
of exposure to undesirable side effects[70, 76]
.
Mean age distribution
Mean age of patients who underwent medical abortion in our study was
25.1±3.73 in the range of (20-30 yrs) which was comparable with the study conducted
by Verma et al in which mean age distribution in study group is 28.14 yrs and 27.92
yrs in control group in the range of 21-30 yrs. Mean age distribution of present study
is also comparable to the study conducted by Sonal k et al (26.44 yrs), Von Hertzen et
al (26.4 yrs)and Guest et al (25.7 yrs).Minority of patients who underwent medical
abortion for the indication of early pregnancy failure belongs to teenage group, but
none of them had any complications which reinforces the fact that medical abortion
saves the patient from the complications of unsafe abortions in developing
countries[70, 77-79]

Parity distribution
70% of women who approached for medical abortion were Multiparous.
Among 84 multiparous women who underwent medical abortion in both study and
control group, 12 patients underwent curettage whereas 72 patient expelled
successfully with drugs. Among the total number of women who underwent curettage
in our study 70.5 % of them were multiparous and 29.4 % were nulliparous which is
controversial to the fact that failure rate of medical abortion in nulliparous women
will be more compared to multiparous.
The parity distribution in the present study is comparable to the study
conducted by Verma et al, Von Hertzen et al, Guest et al and Schaff et al where
majority of the women who approached for medical abortion were
multiparous,[70,78,79,80]

Gestational age in weeks
Cut off for the gestational age taken in our study is 63 days where the success
rate of medical abortion is found to be high (80%). 45% of women in control group
and 48.3 % of women in study group belongs to 8-9 wks of gestation which is
comparable to Von Hertzen et al where also majority of women in both study and
control group belongs to 7-9 wks POG.
Chaudri et al proposed the rate of successful abortions with the 24 hour and
48 hour dosing intervals (95.8% and 93.6%, respectively; P=0.γ8), at 7-9 weeks
period of gestation[70, 78, 79, 82]
.

Induction – Abortion interval
Mean induction to abortion interval in study group was in the range of 5-6 hrs
versus 6-7 hrs in control group with P value of 0.772 .There was no statistically
significant difference between the two which implies the women can be given a
choice of 24hrs regimen which helps her to complete the abortion process within
short span of time. This shorter induction abortion interval in study group is
comparable to the interval reported by Verma et al (4 hrs), Von Herzen et al (4-5
hrs)[70, 78]
.
Whereas it is contrast to longer induction to abortion interval in 24 hour group
than in 48 hour group as reported by Heikinheimo et al, Mentula et al, Hou et al. The
shortest induction abortion interval with the highest complete abortion rate in our
study can also be attributable to 800 mcg of Misoprostol for induction dose as study
done by Ashok et al, Carbonell et al, Chai et al summarizes that high dose of
Misoprostol for induction increases abortion rate with shorter induction abortion
interval [55, 81-85]
.

Complete abortion rate / Success rate
Complete abortion rate with 24 hours was 78.3% compared to 81.6% in 48
hours regimen with P value of 0.29 in our study.The difference in abortion rate
between the two groups is statistically negligible and helps us to prove that 24 hrs
regimen is equally efficacious in achieving complete abortion rate compared to the
standard 48 hour regimen.
This statistically insignificant difference in complete abortion rate between 24
and 48 hour group proved in this study is comparable with the study done by Verma
et al, Von hertzen et al, Schaff et al[70, 78, 80]
.

Side effect profile
Majority of women in both the study and control group had diarrhea and
vomiting as their major side effect, next to abdominal cramps, attributable to
Misoprostol which was managed with non-narcotic analgesia. None of the patients
had any life threatening complications.
Thus the safety profile of 24 hour regimen reported in our study is supported
by other studies conducted by Verma et al, Von hertzen et al, Guest et al, Hou et al
and Mentula et al[70, 78, 81, 82].
69
Based on the above three factors 24 hour regimen which achieves complete
abortion rate with shorter induction abortion interval without compromising its safety
profile can be safely prescribed for the women who approaches for medical abortion
as an alternative to 48 hour group.

Conclusion
Vaginal Misoprostol can be
safely administered 24
hours following
Mifepristone with
promising efficacy.
Efficacy of 24 h interval
was similar to that of 48
h interval for medical
abortion of pregnancy
less than 9 weeks without
compromising the safety
Both the 24 and 48 hour
regimens are equally
efficacious to achieve
complete abortion in early
pregnancy.
Oral Mifepristone 200
mg followed by vaginal
Misoprostol 800
micrograms after 6-
8hours is not as
effective at achieving a
complete abortion
compared with the 36 to
48 hour protocol.
Vaginal Misoprostol,
800 µg, can be used
from 1 to 3 days after
Mifepristone 200 mg,
for early medical
abortion, and need not
be administered strictly
48 hours after
Mifepristone.
75
CONCLUSION
Vaginal Misoprostol can be safely administered 24 hours following
Mifepristone instead of waiting for 48 hours.
Efficacy in achieving complete abortion rate is almost equal to 48 hours
regimen and most acceptable from patients side also.
Reduces multiple outpatient visits, without increasing the rate of surgical
evacuation.
Thus 24 hours regimen serves as an alternative to 48 hour regimen with equal
efficacy and acceptable side effect profile thereby helping women to complete their
abortion process in short span of time, with highest patient satisfaction and cost
effectiveness by preventing multiple clinic visits.

SUMMARY
The present study is a Prospective Case control study “Comparative study of
early (24 hours) versus late (48 hours) Misoprostol administration after Mifepristone
for termination of early pregnancy” was conducted at Adichunchanagiri Institute of
medical sciences from November 2013- October 2015.
All pregnant women of less than 9 weeks of gestation with early pregnancy
failure such as blighted ovum, Missed abortion which was confirmed
sonographically were included in this study (provided they fulfill our inclusion
criteria).
Subjects in study arm was given 200 mg oral Mifepristone followed by 800 mcg
vaginal Misoprostol after 24 hours, where as those in control arm was given 200
mg oral Mifepristone followed by 800 mcg of vaginal Misoprostol after 48 hours.
120 cases were studied.
Mean value for age in control group is 24.89 ±3.74 and in study group it is 25.35
± 3.84 years.
57% of patients in study group and 47% of patients in control group who
underwent medical abortion belongs to lower middle class.
73.3% of women who underwent 48 hour interval regimen and 66.6% of women
who underwent 24 hour interval regimen were Multiparous with the P value of
0.425 which is not significant.
Majority of patients were in the gestational age between 8-9 weeks contributing
46.6 %.
Mean Misoprostol application to abortion interval in study group was in the range
of 5-6 hrs versus 6-7 hrs in control group with P value of 0.772.
77
The Success rate in study group versus control group is 78.3 % versus 81.6 %
with P value of 0.29.
11/58 patients required curettage in study group compared to 6/55 in control
group.
Side effect profile between 24 hour vs 48 hour regimen was statistically
insignificant.
70% of women strongly agreed, 30% were neutral for 24 hr regimen.
Thus vaginal Misoprostol can be safely administered 24 hours following
Mifepristone compared to 48 hours regimen with equal efficacy.
78
RECOMMENDATIONS
1. Medical methods can be safely prescribed for women who undergoes abortion as
it reduces the complications of surgical evacuation of uterus in untrained hands of
rural India.
2. Since most of the women encountered in this study belongs to lower middle class,
who rely on daily wages for their life, instead of prolonging the abortion process
for 48 hours, it can be safely reduced to 24 hours, thus saving their precious time.
