Substance Abuse Disorder Flashcards
Sensitization
increased response to a drug with repeated use, shifting the dose response to the left
Ex.) Cocaine induced movement, cataplexy, and seizures
Withdrawal
the physical and mental symptoms that a person has when they suddenly stop or cut back use of an addictive substance
Tolerance
a state of adaptation in which exposure to a drug induces changes that result in a decrease of one or more of the drug’s effects over time. Shifting the response curve to the right.
Addiction
a primary, chronic, neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations

drugs that activate opiate receptors on neurons
Opiate antagonist
drugs that bind to opiate receptors and block them
Partial agonist
drugs that bind to opiate receptors but not to the same degree as full agonists
