The book provides a comprehensive exploration of the dynamic field of pharmacology and its fundamental principles. It delves into the intricate interactions between drugs and the human body, focusing on pharmacokinetics, which explains the dynamics of drug actions in the body, and pharmacodynamics, which uncovers the mechanisms through which drugs exert their effects. The book also emphasizes the crucial aspects of therapeutics and gene-based therapy, shedding light on modern approaches to disease treatment. Readers will gain insights into drugs that target the autonomic nervous system, influencing functions beyond voluntary control, and drugs that act on the central nervous system, impacting neurological processes. Additionally, the book examines medications affecting renal and cardiovascular functions, playing a significant role in maintaining homeostasis. Moreover, it explores the realm of drugs influencing gastrointestinal function, essential for digestive health.
