Through a series of eye catching charts, the 5th edition of Pharmacological Classification of Drugs, with Doses and Preparations presents a systematized and updated listing of easy to remember drug classifications, which are also therapeutically meaningful.lt is a useful aid to quickly allocate a drug to its appropriate pharmacological/therapeutic category. Such an orderly listing has become particularly relevant in view of the current availability of a very large number of drugs. Each classification is followed by core prescribing information about every member drug, viz. dose, routes and frequency of administration, along with a limited number of leading proprietary (brand) names and dosage forms. This makes the booklet a ready reckoner as well for prescribing with accuracy and confidence.
