quiz 3 Flashcards
drug action
molecular changes produced by a drug at the synapse
drug effect
changes in physiological or psychological functions that result from the drug action
therapeutic effect
desired effect
side effects
all other effects of the drug
changes in the 1800s that increased problems of drug use
chemistry advanced - able to isolate active ingredients from naturally occurring substances and synthesizing new drugs
stimulant
increases alertness, mood, pulse, suppress appetite
dopamine and norepinephrine agonists
amphetamines, meth, cocaine, caffeine, and nicotine
depressant
cause relaxation, drowsiness, depression, slowed pulse, decreased inhibition
include alcohol and sedatives
GABA agonists
opioid
induces sleep, euphoria, and reduce pain
morphine, heroin, vicodin, oxycontin, and other prescription pain killers
endorphin agonists
hallucinogen
induce fantasies, hallucinations, changes in body image
LSD, mushrooms, etc.
serotonin agonists
marijuana
reduces intraocular pressure, reduced nausea, increases appetite, and reduces pain
mix of depressant, stimulant, and hallucinogenic effects
cannabinoid receptor agonists
methods of drug administration
oral - slow
inhalation - fast
injection - intravenous (fast), intramuscular (slower), subcutaneous (slow)
topical - very slow
first order kinetics
half-life - amount of time to remove 50% of the drug from the blood
zero order kinetics
constant rate regardless of drug concentration
1 oz of alcohol per hour
two agonist drug actions
block reuptake (cocaine)
activate receptor directly (nicotine)
two antagonistic drug actions
block receptor directly
inhibit release of NT (botox)
