A drug may have following 4 names:

The generic names diazepam, nitrazepam, flurazepam all are of Benzodiazepines.The WHO chooses recommended International Non proprietary Names (rINN). most countries have used rINNs for many years. USA is an exception. in the UK the British approved Name (BAN) system is being modified such that the rINN name is adopted. eg: adrenaline is the BAN, epinephrine is the RINN name.
