A drug is a chemical substance, which, when administered to a living organism, activates or inhibits the function of a biomolecule, resulting in therapeutic benefits to the patients. The process of finding new medications on the basis of knowledge about a biological target is called drug design. It is also known as rational design. It involves the design of molecules which are similar in shape and charge to the biomolecular target, with which they interact and bind. The process in which the active drug and chemical substances are combined to produce a final medicinal product is called pharmaceutical formulation. This book unfolds the innovative aspects of drug design and formulation which will be crucial for the progress of this subject in the future. It studies, analyzes and upholds the pillars of drug design and formulation and its utmost significance in modern times. This book is a vital tool for all researching or studying pharmaceutical science as it gives incredible insights into emerging trends and concepts.
