Offering a wide array of illustrations and tables in every chapter, this book extensively covers the principles of allosterism in reference to drug action and progresses to a detailed examination of individual ionotropic and G-protein coupled receptor systems-helping those new to the subject understand the importance of allosterism and providing those already working in the field with specific reference information. This title provides in-depth chapters on basic principles of allosterism and its significance at GABAA, 5HT3, nicotinic, and GABAB receptors, ionotropic and metabotropic receptors for glutamate, muscarinic receptors and alpha 2 adrenoceptors to provide a firm foundation to the subject.
