Pharmacology Encyclopedia terms flashcards

Pharmacology has evolved over the years. Originally a scientific discipline that described the overt effects of biologically active chemicals, pharmacology now explores the molecular mechanisms by which drugs cause biological effects. In the broadest sense, pharmacology is the study of how chemical agents, both natural and synthetic (i.e., drugs) affect biological systems. This encompasses investigation of the derivation, chemical properties, physiological and behavioral effects, mechanisms of action, biological transformations, and the therapeutic and non-therapeutic uses of drugs. Pharmacological studies can determine the effects of chemical agents upon subcellular, systemic, physiological or behavioral processes; focus on the treatment and prevention of diseases; or deal with the potential hazards of pesticides and herbicides.
