This is a summary of the fundamentals of experimental pharmacology by M.N. Ghosh. The book was first published in 1971 by the Scientific Book Agency in Calcutta, India. It was well-received by postgraduates and research workers in pharmacology and related fields due to its unique approach. The book aims to provide a theoretical background followed by appropriate experimental techniques. The first edition was introduced by Prof. H. O. Schild, who noted that pharmacology lacks a well-established theoretical foundation, and that facts and observations alone are not sufficient for true advancement in the subject. The book includes worked-out examples to help translate theory into practice. The second edition was published in 1984 by the same publisher. After a gap of 20 years, the third edition appeared in 2005 in a new format with thoroughly revised and updated chapters on receptors and evaluation techniques. The new publisher, Hilton and Company, did an excellent job in bringing out this new third edition. The current thoroughly revised and updated edition includes a new chapter on molecular cell biology and an expanded chapter on biostatistical methods, along with some other chapters that have been expanded.This is a summary of the fundamentals of experimental pharmacology by M.N.
