Pharmacology by definition is the study of how chemical substances affect living tissue and how these substances bind to receptors to affect normal function. This updated pharmacology course (2011) is written specifically for rehab professionals. It includes valuable detailed information on various disease processes, and then introduces the reader to how these chemical agents affect the body either beneficially or adversely at the cellular and organ level. Added bonus in this course is the special application section for therapists, how specific drugs affect exercise, and specific precautions for the rehab professional. This is an updated version of a popular course which now contains sections on vitamins and minerals, drugs used in wound care, and alternative medicine. A must read and valuable reference guide for all therapists. The author is both a PT and an OTR with a PhD in pharmacology.
