Pharmacology and Toxicology

Pharmacology and Toxicology is a comprehensive academic resource that brings together the fundamental principles and advanced concepts of two closely linked disciplines in biomedical science. Designed for students, researchers, and professionals, the book provides an in-depth exploration of drug action, therapeutic applications, and toxicological effects within a structured and accessible framework. The text begins by establishing the scientific foundations of pharmacology, including drug classification, mechanisms of action, and the pharmacokinetic processes that determine how drugs are absorbed, distributed, metabolized, and excreted. It moves seamlessly into pharmacodynamics, offering a clear understanding of receptor interactions, dose-response relationships, and the delicate balance between drug efficacy and safety. A detailed analysis of systemic pharmacology highlights the role of drugs in major physiological systems, including cardiovascular, respiratory, gastrointestinal, renal, endocrine, and immune functions. The discussion extends to the pharmacological management of neurological conditions, with emphasis on neurotransmitter regulation and drug therapies for central nervous system disorders. The toxicology component of the book addresses both theoretical and applied perspectives. Readers gain insights into the mechanisms of chemical toxicity, organ-specific damage, forensic applications, and clinical management of poisoning cases. Contemporary issues such as regulatory frameworks, laboratory animal models, and risk assessment practices are also covered, ensuring relevance to real-world applications. Finally, the text explores emerging frontiers such as pharmacogenomics, nanotechnology in drug delivery, biologics, and artificial intelligence in drug discovery. By bridging classical knowledge with modern innovation, this book serves as an authoritative guide for academic study and future research in pharmacology and toxicology.
