From India:

Are 500 mg plain metformin and 500 mg sustained release metformin equal in total capacity? How does the extended release 500 mg metformin differ from plain?


Both will deliver the same total amount of drug, but the extended release will deliver it over a 24 hour period. Taking a single generic metformin won't last twenty four hours, that's why most people take the generic more than once a day. 500 mg is a very low starting dose. Most people take at least 1000 mg a day.
