The Indian Medical Council (Professional conduct, Etiquette and Ethics) Regulations, 2002, state that "Every physician should, as far as possible, prescribe drugs with generic names and he/she shall ensure that there is a rational prescription and use of drugs.". Undergraduate medical students are introduced to drug nomenclature early on during their pharmacology course. They are told that generic name or, more appropriately, non-proprietary name (usually international non-proprietary name INN), is to be used while writing prescriptions.
