Pharmacology of the Digestive System: Therapeutic Approaches in Gastrointestinal Disorders

The human digestive system is a complex network responsible for the digestion, absorption, and assimilation of nutrients — vital processes that support overall health and well-being. However, this system is frequently affected by a wide range of disorders such as acid-peptic disease, constipation, diarrhea, irritable bowel syndrome, nausea, vomiting, hepatic disorders, and inflammatory bowel diseases. Pharmacology of the Digestive System presents a thorough and clinically relevant overview of drugs used in the treatment of these gastrointestinal (GI) conditions.

This comprehensive volume covers the classification, mechanisms of action, therapeutic uses, side effects, and contraindications of major drug classes targeting the digestive system. From commonly used antacids and proton pump inhibitors to antiemetics, laxatives, antidiarrheals, and hepatoprotective agents, this book bridges basic pharmacology with practical clinical application.

The book also discusses newer treatment strategies, combination therapies, and the impact of gut microbiota on drug metabolism and gastrointestinal health. Special attention is given to pharmacological management of liver diseases, H. pylori eradication, and the growing role of probiotics and herbal formulations in GI therapy.

Key Highlights Include:

✅ Drugs for Acid-Peptic Disorders: Antacids, H2 blockers, proton pump inhibitors, and mucosal protectants
✅ Antiemetics and Prokinetic Agents: For nausea, vomiting, and motility disorders
✅ Laxatives and Antidiarrheals: Classification, mechanisms, and clinical use
✅ Drugs for Hepatic Disorders: Hepatoprotective drugs, antivirals, and enzyme replacements
✅ Therapies for Inflammatory Bowel Disease (IBD): Aminosalicylates, corticosteroids, immunosuppressants, and biologics
✅ Antimicrobial Therapy for GI Infections: H. pylori treatment regimens and antibiotics for intestinal infections
✅ Pharmacokinetics and Safety: Drug absorption in GI tract, metabolism, and drug-food interactions

Designed for medical, pharmacy, and paramedical students, as well as practicing clinicians and researchers, Pharmacology of the Digestive System serves as a reliable and up-to-date guide for mastering GI therapeutics. With clear explanations and a logical structure, this book is ideal for both academic learning and clinical reference.
