Description Morphine is a drug commonly used in the management of moderate to severe nociceptive pain, such as pain due to cancer, surgery or trauma Morphine is well absorbed through the gastrointestinal mucosa However, it undergoes substantial hepatic firstpass effect Therefore, its oral bioavailability is relatively low (~25%)This course will clarify any confusion about Pharmacokinetics and its calculations In this course of Pharmacokinetics we will learn about the followings;Antibody Pharmacokinetics and Pharmacodynamics EVELYN D LOBO, 1 RYAN J HANSEN, 1 JOSEPH P BALTHASAR 2 1 Global PK/PD and Trial Simulations, Lilly Research Laboratories, Lilly Corporate Center, Indianapolis, Indiana
