Key Concepts in Pharmacology
Pharmacology involves pharmacokinetics, pharmacodynamics, and drug-receptor interactions. Understanding drug absorption, distribution, metabolism, and excretion, along with therapeutic effects and toxicity, is fundamental for effective drug therapy.
2.1 Pharmacokinetics: Absorption, Distribution, Metabolism, and Excretion
Pharmacokinetics examines how the body processes drugs, focusing on absorption (how drugs enter the bloodstream), distribution (how drugs spread throughout the body), metabolism (how drugs are broken down), and excretion (how drugs are eliminated). Understanding these processes is crucial for determining drug dosing, efficacy, and safety.
2.2 Pharmacodynamics: Mechanism of Drug Action
Pharmacodynamics explores how drugs interact with biological systems to produce effects. It involves drug-receptor binding, signal transduction, and dose-response relationships. Understanding these mechanisms helps predict therapeutic effects, side effects, and variability in patient responses, ensuring safe and effective drug therapy.
2.3 Drug-Receptor Interactions
Drug-receptor interactions involve drugs binding to specific cellular receptors, triggering biological responses. Receptors can be on cell membranes or inside cells. Drugs act as agonists (activating receptors) or antagonists (blocking activation). Binding affinity and efficacy determine therapeutic effects. Understanding these interactions is key to developing targeted therapies and predicting drug responses.
Major Drug Classes
Major drug classes include antimicrobials, cardiovascular drugs, and CNS agents. Each class targets specific physiological systems, treating infections, heart conditions, and neurological disorders with tailored mechanisms of action.
3.1 Antimicrobials: Antibiotics, Antivirals, and Antifungals
Antimicrobials target pathogens, preventing infection spread. Antibiotics inhibit bacteria, antivirals block viral replication, and antifungals treat fungal infections. Common drugs include penicillins, acyclovir, and fluconazole. Proper use is crucial to avoid resistance and ensure efficacy.
3.2 Cardiovascular Drugs: Antihypertensives, Antiarrhythmics, and Anticoagulants
Cardiovascular drugs manage heart conditions. Antihypertensives lower blood pressure, such as ACE inhibitors. Antiarrhythmics regulate heart rhythm, like beta-blockers. Anticoagulants prevent clots, including warfarin. These drugs improve heart function and reduce complications, essential for patient care.
3.3 Central Nervous System Drugs: Analgesics, Antidepressants, and Antipsychotics
CNS drugs target brain and nervous system disorders. Analgesics relieve pain, with NSAIDs reducing inflammation and opioids binding to pain receptors. Antidepressants, like SSRIs, treat depression by increasing neurotransmitters. Antipsychotics manage psychosis by blocking dopamine receptors, with typical and atypical types varying in side effects. These drugs improve mental health and quality of life.
