Introduction to the principles of pharmacology and receptors including drug receptor properties, drug dose response curves, mechanisms of signal transduction, and common receptor subtypes. This module reviews principles of neurobiology, and explores concepts of pharmacology and medicinal chemistry as applied to the autonomic and somatic nervous systems. In this module, a study of the basic principles of drug action is presented for specific drug classes including: the chemical properties, mechanisms of drug action, and routes of administration, clinical uses, disposition, contraindications, adverse reactions, clinically significant drug interactions, and drug disease interaction. The basic concepts of toxicology and adverse drug reactions are also introduced in this module. (Last offered in Fall 2019 due to curricular revision).
