Sedative-Hypnotic Drugs• Sedative-hypnotic drugs are central nervous
system depressants that produce relaxing to
sleep-inducing effects
• Three main types of
sedative-hypnotic
drugs:o Barbiturates
o Nonbarbiturate sedatives
o Minor tranquilizers
![Page 6: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/6.jpg)
Classification• Classified based on potency and the length of time
they act:
o Ultra-short-acting
o Short-acting (less than 4 hours)
o Intermediate-acting (4 to 6 hours)
o Long-acting (more than 6 hours)
• Drugs that take effect rapidly
have a higher abuse potential
than slow-acting drugs
![Page 7: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/7.jpg)

Effects of Barbiturates• Produce a depressed, mood-altering action on the
central nervous system – act on GABA
• Slow activity of the cardiovascular, muscular and
respiratory systems
• Can cause confusion, inadequate emotional
control, slurred speech, poor judgment, and
intoxication
![Page 10: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/10.jpg)
Dangers• Tolerance
• Lethal in combination with alcohol
• Withdrawal severe, can be fatal
![Page 11: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/11.jpg)
Medical Uses
• Used primarily to treat
o Anxiety
o Insomnia
o Convulsive disorders
• Short-acting barbiturates
continue to be used for
anesthetic purposes
![Page 12: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/12.jpg)

Non-barbiturate Sedatives• Older drugs with similar actions to barbiturates
• With the advent of safer drugs, rarely used now
![Page 14: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/14.jpg)
Minor Tranquilizers• Benzodiazepines
(Librium and Valium)
o Used primarily to treat anxiety
o Addictive; produces tolerance and withdrawal
symptoms
o Have a wider margin of safety, fewer side effects,
and less severe side effects than barbiturates
![Page 15: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/15.jpg)
Hypnotics
• Non-benzodiazepines (Ambien, Lunesta, Sonata)
o Short-term treatment of
insomnia
o Short half-life
o Less dependency, less
tolerance, less carry-
over
![Page 16: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/16.jpg)

Mental Illness• The National Alliance on Mental Illness defines
mental illnesses as: “medical conditions that disrupt
a person’s thinking, feeling, mood, ability to relate
to others and daily functioning”
![Page 22: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/22.jpg)
History
• Before 1950, people with
mental illness were
subjected to abysmal
treatment
• Depression was treated
with amphetamines;
other types of mental
illnesses were treated
with sedatives
![Page 23: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/23.jpg)
History• Electroconvulsive therapy (ECT), first developed in
1938, was used to treat depression and psychosis
• Electrical activity in the brain is temporarily interrupted and a seizure within the brain is triggered
• Many patients experienced adverse cognitive effects
• Despite concerns, ECT is still a treatment option
![Page 24: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/24.jpg)
Demographics• 10-15% of the general population receive drugs for
emotional problems each year
• 43% of people with mental disorders reside in the US
and Europe
• 1 in 3 Americans suffer from a mental disorder
• Antidepressants are the medication most frequently
used by people aged 18–44
![Page 25: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/25.jpg)

Diagnosis of Mental Disorders
• DSM-5 criteria
• Clinically significant distress or impairment in social,
academic (occupational) or other important areas
of functioning
• Not attributable to the physiological effects of a
substance or another medical condition
• Dual-diagnosis
• VERY QUICK OVERVIEW – YOU WILL NOT BE ABLE TO
DIAGNOSE ANYONE, EVEN YOURSELF!
![Page 27: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/27.jpg)
It is important to rule out substance use
as a cause of symptoms because
A. Patients could be lying about their use of drugs
B. Intoxication can resemble some symptoms of mental disorders
C. A patient can’t be diagnosed with both mental illness and substance abuse

Anti-depressant Medications
oMonoamine oxidase inhibitors (MAOIs)
o Tricyclic antidepressants
o Selective serotonin reuptake inhibitors
(SSRIs)
o Serotonin and norepinephrine reuptake
inhibitors (SNRIs)
oAtypical antidepressants that do not fall
into one of the above categories
![Page 37: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/37.jpg)
Monoamine Oxidase Inhibitors
• Monoamine oxidase (MAO) is an enzyme on the
outer membranes of mitochondria – inactivates the
neurotransmitters serotonin, dopamine, and
norepinephrine
• MAOIs block the action of monoamine oxidase
• Interact dangerously with dextromethorphan,
Demerol and SSRIs and some foods
![Page 38: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/38.jpg)
Tricyclic Antidepressants
• Tricyclics are also effective in moderating pain, and can be beneficial in treatment of the eating disorder bulimia
• Common side effects are distorted vision, tachycardia, dry mouth, constipation, sleepiness, and urinary retention
• If patients cease taking tricyclics abruptly, they demonstrate withdrawal symptoms
• Even at low dosage, tricyclics can be toxic – excessive levels can be fatal, alcohol intensifies this effect
![Page 39: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/39.jpg)
SSRIs• Selective serotonin reuptake
inhibitors (SSRIs) o Antidepressant medications that increase the
concentration of serotonin in the brain
o Reduce aggressive and violent behavior
o Adverse effects include sexual dysfunction,
increase in weight, and altered sleep patterns
o Not much more effective than placebos
![Page 40: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/40.jpg)

Atypical Antidepressants• Nefazodone (Serzone)
o No longer available in the US
o Reported as causing severe liver failure
• Trazodoneo Mood elevator
o Side effects may include confusion, concentration difficulties, headaches, and nervousness
• Mirtazapine o May cause mood changes, unusual thought processes, seizures, lowered
libido, and changes in menstrual cycle

o Also used for smoking cessation and seasonal affective disorder
o Side effects are usually mild
![Page 42: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/42.jpg)
SNRIs
• Serotonin and norepinephrine reuptake inhibitors
(SNRIs)o Work by decreasing the reabsorption of both serotonin and
norepinephrine in the brain
o Side effects may include pain in the eyes, vision blurring, or blindness
o May cause a variety of other side effects, from diarrhea and agitation to
irregular heartbeats and convulsion
![Page 43: SOC 204 Goldberg Ch 9 & 10 Week 5](https://reader030.vdocuments.site/reader030/viewer/2022013105/55a73c0d1a28abd5258b4709/html5/thumbnails/43.jpg)

Medications for Bipolar Disorder/Manic Episode
• Lithium o Effective for acute mania and prevents
recurrence
o Maximal benefit is achieved in one to two weeks
o Effective for unipolar depression not responsive to other antidepressant drugs
o The therapeutic window is small – three to four times the therapeutic level can cause grave consequences
• Chlorpromazineo Fewer toxic side effects
