Pharmacological Basis of Therapeutics Handbook: A Mechanism-Based Guide to Drug Action, Prescribing, and Adverse Effects

What if pharmacology could be understood as a system of connected principles rather than memorized as endless lists of drugs, doses, and side effects? Pharmacological Basis of Therapeutics Handbook is a mechanism-centered reference for readers who want to understand not only what a drug does, but why it works, why it causes harm, and how those principles shape safer therapeutic decisions. Instead of separating mechanisms, clinical effects, interactions, and adverse reactions, this handbook shows how they arise from the same underlying pharmacology. Beginning with receptor theory, dose-response relationships, pharmacokinetics, membrane transport, metabolism, pharmacogenomics, drug interactions, monitoring, and pharmacovigilance, the book builds a foundation that is applied throughout major therapeutic areas. Coverage extends across autonomic and neuropharmacology, cardiovascular and renal medicine, respiratory disease, endocrine and metabolic disorders, gastrointestinal and immune therapeutics, antimicrobial therapy, cancer pharmacology, toxicology, and special populations. Inside, readers will find: - Mechanism-based explanations connecting molecular targets to clinical effects- Clear treatment of therapeutic index, dosing principles, interactions, and predictable toxicity- Practical discussion of drug selection, monitoring, organ impairment, pregnancy, childhood, and older age- Learning objectives, chapter overviews, key points, clinical examples, tables, and focused visual explanations- Evidence-aware discussion distinguishing proven efficacy from uncertain or oversimplified mechanisms Designed for medical and pharmacy students, trainees, and practicing clinicians who want more than a protocol, this handbook turns pharmacology into a framework for reasoning. Understand the mechanism. Predict the effect. Recognize the risk. Make better-informed therapeutic decisions.
