This is called first-order metabolism and is characterized by a half-life, the time period over which the drug concentration will decrease by half. How Drugs are Developed: drugs were developed by accident, this involves designing and synthesizing compounds based on the known structure of a specific target molecule Drug Responses: Receptors: agonists cause an action; antagonists: opposes the action of the agonist Antagonists occupy a receptor site and prevent other molecules, such as agonists, from occupying the same site and producing a response. Antagonists produce no direct response Pharmacokinetics: The study of what happens to a drug from the time it is put into the body until the parent drug and all metabolites have left the body. Pharmacokinetics represent the drug absorption into, distribution and metabolism within, and excretion from the body. Absorption: is the movement of a drug from its site of administration into the bloodstream for distribution to the tissues. Distribution: refers to the transport of a drug by the bloodstream to its site of action, first to those areas with extensive blood supply. Areas of rapid distribution include the heart, liver, kidneys, and brain; while areas of slower distribution include muscle, skin, and fat Protein Binding: Protein binding may lead to an unpredictable drug response called a drug-drug interaction. A drug-drug interaction occurs when the presence of one drug decreases or increases the actions of another drug that is administered concurrently (i.e., given at the same time). Metabolism: Metabolism of drugs occurs mostly in the smooth endoplasmic reticulum of cells in the liver. A drug that is absorbed from the intestine must first pass through the liver before it reaches the systemic circulation. If a large proportion of a drug is chemically changed into inactive metabolites in the liver, then a much smaller amount of drug will pass into the circulation (i.e., will be bioavailable) thus creating a first-past effect that reduces drug bioavailability. Hepatic metabolism involves the activity of a very large class of enzymes known as cytochrome P-450 enzymes First Pass Routes: Hepatic, arterial, Oral, Portal, venous, Rectal Phase I: It begins with preclinical testing phases, which include in vitro studies (using tissue samples and cell cultures) and animal studies, healthy people without the disease. Phase I studies is to determine the optimal dosage range and the pharmacokinetics of the drug and to ascertain if further testing is needed. II: Clinical (human) studies follow the preclinical phase. This phase involves small numbers of volunteers who have the disease that the drug is designed to diagnose or treat and are closely monitored for the effectiveness of treatment Cytochrome P450 metabolism: the family of enzymes that metabolizes drugs; CYP P450 (mixed-function oxidase reaction) catalyzes the metabolism of a large number of diverse drugs and chemicals that are highly lipid soluble (lipophilic) [Show More]
