The chapter discusses the fundamentals of experimental pharmacology, highlighting the thoroughly revised and updated third edition of the book authored by M.N. Ghosh. This edition includes new and expanded chapters on Molecular Cell Biology, Biostatistical Methods, and various pharmacological topics such as receptor pharmacology, angiotensin, prostaglandins, nitric oxide, and toxicity studies. The book aims to provide a theoretical background and practical experimental techniques, making it a valuable resource for postgraduates and researchers in pharmacology. The first edition, published in 1971, was widely accepted for its unique approach compared to other books on the subject. The late Prof. H. O. Schild praised the book for its concise methods and general principles, emphasizing the importance of combining theory with practical examples. The second edition, published in 1984, and the third edition, published in 2005 by Hilton and Company, have been well-received for their comprehensive coverage and updated content.The chapter discusses the fundamentals of experimental pharmacology, highlighting the thoroughly revised and updated third edition of the book authored by M.N.
