This course, to be offered primarily face-to-face, introduces scientifically sophisticated students to all aspects of modern pharmacology including pharmacodynamics (how drugs elicit biological responses) and pharmacokinetics (drug absorption, distribution, metabolism, and excretion). We will discuss major classes of drugs commonly used to treat illness in modern medical and veterinary practice. Agents considered will include those acting on the nervous system, the immune system, the cardiovascular, respiratory and gastrointestinal systems, and those used in treating cancer and infectious diseases. We will also consider vaccination to prevent illness.
