Substance abuse disorders

Drug use – when drugs are used to treat an illness, prevent a disease and improve health condition, it is termed drug use

Drug abuse – intake of drugs for reasons other than medical in a manner that affect physical or mental functioning is termed drug abuse.

Tolerance – it refers to a condition where the user needs more and more of the drug to experience the same effect. Smaller quantities, which were sufficient earlier, are no longer effective and the user is forced to increase the amount of drug intake

3

Intoxication - it is a condition that follows the administration of a psychoactive substance and results in disturbance in the level of consciousness, cognition, perception, judgment, affect, or behavior, or other psych physiological functions and responses.

Dependence – dependence syndrome is a cluster of physiological, behavioral, and cognitive phenomena in which the use of a substance or a class of substances taken on a much higher priority for a given individual than other behaviors that once had greater values

4

Psychological dependence – psychological or psychic dependence refers to the experience of impaired control over drinking or drug use while physiological or physical dependence refers to tolerance and withdrawal symptoms.

Harmful use – pattern of psychoactive substance use that is causing damage to health. It may be physical or mental

5

Abuse – in DSM IV, psychoactive substance use is defined as a maladaptive pattern of use indicated by continued use despite knowledge of having a persistent or recurrent social, occupational, psychological or physical problem that is caused or exacerbated by the recurrent use in situations in which it is physically hazardous.

Withdrawal symptoms - when the drug intake is stopped, withdrawal symptoms are experienced. Physical dependence gives rise to withdrawals such as tremors and vomiting. Psychological dependence causes withdrawal symptoms like restlessness or depression.

INTRODUCTION

Alcoholism is the most common psychiatric disorder. Epidemiological studies carried out in India revealed that 20 to 40% of subjects aged above 15 are current users. Nearly 15 to 30% of patients seeking admission in psychiatric facilities are for alcohol related problems.

Alcoholism is classified under F10-F19, i.e. mental and behavior disorders due to psychoactive substance use in ICD 10 classification

46

DEFINITION

1. Alcoholism refers to the use of alcoholic beverages to the point of causing damage to the individual and society or both.

2. Alcoholism is defined as a chronic disease manifested by repeated drinking that produces injury to the drinker’s health or to his society or economic functioning.

47

PREVALANCE

In India the incidence of alcohol dependence is 2% and 20 to 40% of population aged above 15 are current users.

48

WHAT IS ALCOHOL?

Alcohol includes liquors, beer and wine.

Chemical name: ethanol

Street names: booze, hooch, moonshine, sauce etc..

Mode of administration: oral

49

HOW IT ACTS?

Acts on CNS in two ways

1. It potentiates GABA activity

2. It decreases glutamate activity In both cases the outcome is

depression.

50

PROPERTIES OF ALCOHOL

Clear colored liquidStrong burning tasteRate of absorption into blood is more faster

than its elimination rate.Absorption is slower in the presence of foodA small amount is excreted through urine and

small amount is exhaled.

51

Conti..

A conc. of 80-100mg per 100ml of blood is considered as intoxication

A person with 200-250mg per 100ml of blood will be toxic, sleepy, confused, and his thought process will be altered.

If the conc. is 300mg per 100ml of blood, the person may loose consciousness.

52

Conti…

A conc. of 500mg per 100ml of blood is fatalAll the symptoms change according to the

85

Treatment

Symptomatic Rx involve respiratory support, fluid replacement, emergency measures for trauma etc

86

Treatment for withdrawal symptoms

1. Detoxification *benzodiazepines (chlordiazepoxide 80-

200mg/day) * diazepam 40-80 mg/day * 100mg of thiamine twice daily fro 3-5

days, then oral administration for 6 months *anticonvulsants if necessary * maintain electrolyte balance

87

Cont…

2. Alcohol deterrent therapyDeterrent agents are those which are given to

desensitize the individual to the effects of alcohol and maintain abstinence. The most commonly used drug is disulphiram(tetraethyl thiuram disulfide) or antabuse

88

Psychological Rx

Motivational interviewingGroup therapyAversive conditioningCognitive therapyRelapse prevention techniquesCue exposure technique

89

Disulfiram

It is used to ensure abstinence in the treatment of alcohol dependence. Its main effect is to produce a rapid and violently unpleasant reaction in a person who ingests even a small amount of alcohol while taking disufiram

90

Dosage

Tablets 200-500 mgInitial dose – 500 mg/ day orally for initial 2

weeksMaintenance dose later, of 250mg/dayDose should not exceed 500mg/day

91

Mechanism of action

When alcohol is consumed, it is metabolized by the body into acetaldehyde, a very toxic substance , that causes many ‘hang over’ symptoms. Disulfiram interferes with the metabolism of alcohol that increases the acetaldehyde level (10 times > in normal alcoholics) and it produces a wide variety of unpleasant reactions called Disulfiram Ethanol Reaction (DER)

92

DER symptoms

FlushingNauseaVomitingSweatingThirstThrobbing headacheRespiratory difficultyChest painPalpitationsDyspnea

HyperventilationTachycardiaHypotensionSyncopeSevere uneasinessWeaknessVertigoBlurred visionconfusion

93

Side effects Contraindications

FatigueDermatitisImpotenceOptic neuritisMental changesAcute

polyneuropathyHepatic damage

Pulmonary and cardiovascular disease

Use with caution in patients with nephritis, brain damage, hypothyroidism, diabetes, hepatic disease, seizures and poly drug dependence

94

Nurses responsibility in Deterrent therapy

Get informed consent before therapy starts

Administer the medicine after 12 hours of the last ingestion of alcohol

Strictly inform the patient not to take even a small amount of alcohol after therapy starts

Instruct him about reaction.

Avoid any topical application, and food stuffs , medicines containing alcohol

Patient should not take any CNS depressants or OTC medicines

Avoid driving and activities require alertness

Instruct them DER will last for 1-2 weeks after the last dose

Importance of follow up

95

Alcoholics anonymous (AA)

Found in USA on 10th June 1935 by two alcoholic men, Dr. Bob Smith and Bill Wilson.

AA considers alcoholism as a physical, mental and spiritual disease, a progressive disease which can be arrested but not cured

Members attend group meetings usually twice a week on long term basis

Each member is assigned a support person, from whom he may seek help when the temptation to drink occurs

96

Once sobriety is achieved, he is expected to help others

The only requirement for membership is the desire to stop drinking

Their primary purpose is to help each other stay sober and help other alcoholics to achieve sobriety.

A l - A n o nSupport group for wives of alcoholics, started by

Mrs. Anne, wife of Dr. BobA l - A t e e nProvides support to teen children of alcoholics

97

Nursing management

Assessment through CAGE questionnaireC- Have you ever felt you ought to CUT

DOWN on your drinking?A- Have people ANNOYED you by criticizing

your drinking?G- Have you ever felt GUILTY about your

drinking?E – Have you ever had a drink first thing in

the morning as an EYE OPENER to steady your nerves or get rid of a hangover?

98

Nursing diagnosis

Risk for injury related to hallucinosis, acute intoxication evidenced by confusion, disorientation, inability to identify potentially harmful situations

Altered health maintenance related to inability to identify, manage or seek out help to maintain health, evidenced by various physical symptoms, exhaustion, sleep disturbance etc.

Ineffective denial related to weak, underdeveloped ego, evidenced by lack of insight, rationalization of problems, blaming others, failure to accept responsibility of his behavior
