Elementary Pharmacology and Toxicology

Elementary Pharmacology and Toxicology provides a comprehensive exploration of the fundamental and advanced concepts that define modern drug science and toxicological studies. Designed as a rigorous academic reference, the book bridges the gap between the principles of pharmacology and the critical aspects of toxicology, offering readers a unified perspective on how drugs interact with biological systems and how toxic agents exert harmful effects. The text begins with the historical foundations and essential principles of pharmacology, introducing readers to drug discovery, development, classification, and the processes of pharmacokinetics and pharmacodynamics. It then delves into the mechanisms of drug action, therapeutic agents across diverse physiological systems, and the scientific basis for clinical interventions. Equally significant is its treatment of toxicology, where the book examines dose–response relationships, toxicokinetics, mechanisms of cellular injury, and organ-specific toxic effects. Special emphasis is placed on systemic toxicology, covering the liver, kidneys, heart, lungs, and nervous system. The volume also extends into environmental and industrial toxicology, addressing the impact of pesticides, heavy metals, radiation, and chemical warfare agents, alongside the practical applications of forensic toxicology. Recognizing the rapidly evolving landscape of biomedical sciences, the book integrates discussions on pharmacogenomics, personalized medicine, nanotechnology in drug delivery, and regulatory aspects of drug safety evaluation. With its clear organization, evidence-based coverage, and forward-looking approach, Elementary Pharmacology and Toxicology serves as an essential academic resource for students, educators, and professionals seeking a deeper understanding of drug action, safety, and emerging trends in pharmacological sciences.
