Fundamental Principles of Pharmacology in Rang & Dale
Pharmacodynamics
Pharmacodynamics describes how drugs exert their effects on the body. Rang & Dale elucidate this by exploring mechanisms of drug-receptor interactions, dose-response relationships, and the factors influencing drug efficacy.
- Receptor Types: Includes ion channels, G-protein-coupled receptors, enzymes, and nuclear receptors.
- Agonists and Antagonists: Explains how drugs activate or inhibit receptors.
- Signal Transduction: Details pathways like second messengers (cAMP, IP3, DAG).
- Therapeutic Index: Discusses the margin of safety for drugs.
Pharmacokinetics
Pharmacokinetics focuses on how the body absorbs, distributes, metabolizes, and excretes drugs (ADME). Rang & Dale use diagrams and tables to illustrate these processes across different routes and conditions.
- Absorption: Factors affecting bioavailability, such as pH, formulation, and blood flow.
- Distribution: Volume of distribution, blood-brain barrier considerations.
- Metabolism: Enzymatic processes in the liver, phase I and phase II reactions.
- Excretion: Renal clearance, tubular secretion, and reabsorption.
Major Drug Classes and Their Pharmacology
Autonomic Pharmacology
Understanding autonomic drugs is essential for managing cardiovascular, respiratory, and other systemic disorders.
- Adrenergic Drugs: Agonists (e.g., adrenaline, noradrenaline) and antagonists (e.g., beta-blockers).
- Cholinergic Drugs: Muscarinic and nicotinic agents, their uses and mechanisms.
- Adverse Effects: Sympathetic and parasympathetic imbalance consequences.
Central Nervous System Pharmacology
This section covers drugs affecting mood, cognition, and neurological disorders.
- Antidepressants: SSRIs, SNRIs, tricyclics, mechanisms, and side effects.
- Anxiolytics and Sedatives: Benzodiazepines, barbiturates, and their pharmacological profiles.
