CH. 1 Introduction to Pharmacology Flashcards
Pharmacodynamics
Study of the action of drugs on living tissue
Pharmacokinetics
Study of the processes of drug absorption, distribution, metabolism and excretions
Pharmacotherapeutics
Study of the use of drugs in treating disease
Pharmacy
Science of preparing and dispensing medicines
Posology
Study of the amount of drug that is required to produce therapeutic effects
Toxicology
Study of the harmful effects of drug use on living tissue
Therapeutic effect
Desired, or intended drug effect to alleviate some condition or symptom of disease
Drug indication
Intention or indicated uses for any drug
Contraindications
Conditions or situations in which a certain drug should not be administered
Side effects
Drug effect other than the therapeutic effect that is usually undesirable but not harmful
Adverse effects
Undesirable and potentially harmful drug effect
Toxic effects
Undesirable drug effect that implies drug poisoning; can be very harmful or life threatening
Site of action
Location within the body where the drug exerts its therapeutic effect
Mechanism of action
Explains how a drug produces its effects
Receptor Site
specific location on certain cells for certain drugs and normal body substances
Agonists
Drugs that bind to specific receptors and produce a drug action
Antagonists
Drugs that bind to specific receptors and block agonist drug action or cellular functions are called antagonists
Competitive antagonism
When both agonist and antagonist drugs bind to the same receptor and are administered together, they compete with each other for the same receptor site.
Graded dose-response curve
Used to evaluate drug response among different drugs. eX. ED50
Potency
Measure of the strength, or concentration, of a drug required to produce a specific effect
