Flashcards in Exam 4 Principles of Addiction and Drugs of Abuse Deck (123):

What factors increase the potential for abuse?

1) Potency of the drug= greater potency = more likely to abuse
2) Quick/rapid onset of action
3) Inexpensive
4) Easy to obtain/distribute


What is drug abuse?

When drugs are used in a manner or ant inconsistent with medical or social patterns of a culture


What is Physical dependence?

-Changes that have occurred in the body after repeated use of a drug that necessitates the continued administration of a drug to prevent a withdrawal syndrome

-NOT an addiction (can exist without addiction)
-Addicts are usually physically dependent on drug they are abusing

-pt’s who use opiates for chronic pain management are likely to be physically dependent


What is Psychologic dependence?

-Perceived “need” or “craving” for a drug
-often feel that they cannot function w/o continued use of that substance

-Physical dependence disappears w/in days or weeks after drug use stops, but psychological dependence can last much longer

-Psychological dependence is primarily reason for relapse (initiation of drug use after period of abstinence).


What is Tolerance?

***With repeated dosing, the dose of drug must be increased to produce same effect
--or w/ consecutive dosing, same dose of drug produces less of an effect

-Need a HIGHER dose to produce the desired effect
**Psychoactive drugs produce “central” tolerance (function or behavioral)
-definite decrease in the response of brain tissue to constantly increasing amounts of the drug

-NOT the same as metabolic tolerance (as we discussed in basic principles) caused by accelerated rate of metabolism of drug
--insignificant factor in tolerance observed in humans to most psychoactive drugs


What is withdrawal syndrome?

-Can range from mildly unpleasant to life-threatening

--dependent on a number of factors:
1) drug being used
2) dose and route of administration
3) concurrent use of other drugs
4) frequency and duration of drug use
5) age, sex, health and genetics of the individual user


What is addiction?

-Compulsive drug-seeking behavior where acquiring and using a drug becomes most important activity in user’s life

-loss of control regarding drug use

-Continued use despite serious medical and/or social consequences
w/ addiction, there is always psychological dependence


What are the Behavioral signs of addiction?

1) preoccupation with obtaining the drug
2) compulsive use in spite of adverse consequences
3) relapse following periods of abstinence
4) anal retentive
5) obsessive compulsive
6) controlling
7) manipulative


What is Habituation?

physiological tolerance to or psychological dependence on a drug, short of addiction


What is enabling?

-The behavior of others (e.g. family and friends) who are associated w/ drug addict, results in continued drug abuse

--this is an inappropriate coping mechanism by the “enabler” that negatively reinforces that addict’s behavior

--often requires family counseling


What is abstinence?

-The state of being free of drugs
--goal of drug treatment programs


What is abuse?

-non-sanctioned use of controlled substances
-use of legal pharmaceuticals outside of the scope of sound medical practice


All controlled substances substances have abuse potential or are immediate precursors to substances with abuse potential what can they alter?

abused to alter:
1) mood
2) thoughts
3) feelings
4) actions on CNS
5) alleviate pain, anxiety, depression, induce sleep, energize


What is the Treatment: for Abuse?

1) Multifactorial approach
-counseling for behavioral change

2) Individual must have the desire to stop for best chance of success


Drug abuse in Kids?

-Access to store medications at home
--contributing factor to prescription medication abuse
--especially problematic for children and teenagers

-a leading cause of visits to the ER due to accidental or intentional overdose


What are the Considerations for Children:

-many drugs must be given to children in doses that are smaller than the adult dose

-children have increased membrane permeability

-allows drugs to be absorbed more quickly and more easily
-doses are determined by the manufacturer
-dosing is based on the weight of the child
-typically, children receive half of the adult dose


What are the Trends for abuse?

1) more children are abusing prescription drugs than cocaine, heroin, hallucinogens and Ecstasy combined

2) Opiates cause more overdoses in adolescents than cocaine and heroin combined


What is misuse?

-misuse of a drug differs from abuse, as misuse implies that drug is being used inappropriately for patient’s disease state

--using the wrong drug for wrong problem, or the wrong dose for a longer period that prescribed


What is Chemical dependency for abuse?

-a primary, chronic, progressive, relapsing disease process with genetic, psychosocial and environmental factors influencing its development and manifestations

-progressive nature of addiction
■ experimental→ social use → abuse → addiction
■ majority of “social users” will become addicted


What are the gateway drugs?

Nicotine and Alcohol
-caution w/ dental patients who report a history of this disease
****remember: relapsing disease***
-NO opiates, benzodiazepines, or nitrous oxide
-could make a recovered patient w/ alcoholism relapse


How do you determine? Drug choice

-Strength and efficacy of a given drug play important roles in whether a drug is selected by the drug abuser
-Effects vary significantly (largely dependent on dose and route of administration)
-concurrent use of other drugs is common
-boost desired effects or counter unwanted effects


Basic principles:

-when comparing drugs in the same group, the time required to produce physical dependence is _________with a rapidly metabolised drug and _________ with a slowly metabolized drug
-The time course of withdrawal reactions is related to the ___________of the drug
-shorter the half life, the __________the withdrawal occurs

- shortest
- longest

- half-life of the drug
- quicker


What are the common reasons for relapse following treatment for drug addiction?

-Primary reason = psychological dependence
-perceived “need” or “craving” for a drug, often feel that they cannot function w/o continued use of substance

-Physical dependence disappears w/in days or weeks after drug use stops, but psychological dependence can last much longer

-Caution w/ dental patients who report a history of disease (chemical dependency)
--No opiates, benzodiazepines or nitrous oxide - could make a recovered patient w/ alcoholism relapse
