Introduction to Pharmacology

Definition and Scope

• Pharmacology is the study of the effects of drugs on living organisms
• It involves the study of the interactions between drugs and biological systems
• Pharmacology is a multidisciplinary field that combines principles from biology, chemistry, medicine, and pharmacy

Branches of Pharmacology

• Pharmacokinetics: the study of the absorption, distribution, metabolism, and excretion of drugs
• Pharmacodynamics: the study of the effects of drugs on biological systems
• Pharmacotherapeutics: the study of the use of drugs in the treatment of diseases
• Toxicology: the study of the adverse effects of drugs and other substances on living organisms

Drug Development and Approval

• Drug discovery: the process of identifying and synthesizing new drugs
• Preclinical testing: testing of drugs in laboratory animals and in vitro systems
• Clinical trials: testing of drugs in human subjects
• FDA approval: the process of obtaining approval from the US Food and Drug Administration for the marketing and sale of a drug

Drug Action and Mechanisms

• Receptors: proteins that bind to drugs and trigger a response
• Enzymes: proteins that catalyze chemical reactions and can be affected by drugs
• Ion channels: proteins that regulate the flow of ions across cell membranes and can be affected by drugs
• Signal transduction pathways: complex systems of molecular interactions that can be affected by drugs

Drug Interactions and Side Effects

• Drug-drug interactions: interactions between two or more drugs that can affect their efficacy or safety
• Drug-food interactions: interactions between drugs and food that can affect their efficacy or safety
• Side effects: unwanted effects of drugs that can range from mild to severe
• Adverse drug reactions: serious and potentially life-threatening side effects of drugs

Special Topics in Pharmacology

• Personalized medicine: the use of genetic information to tailor drug therapy to individual patients
• Pharmacogenomics: the study of the genetic factors that influence drug response and toxicity
• Cancer pharmacology: the study of the use of drugs in the treatment of cancer
• Neuropharmacology: the study of the effects of drugs on the nervous system
