Is there any difference btween drugs of different companies with same salt? Eg CEFTUM 500 of GSK costs 86/tab but OMNIXIM from CIPLA is cheaper. And there are many drugs with same salt even within same company which are priced differently, eg OMNIXIM & CEFADUR CA from CIPLA have  same salt but different prices. Reason?
