Hello, thanks for the query. Both the products are same. The er refers to extended release, which means the drug is released slowly over 12 hours in the gut. That helps maintain a longer therapeutic level. It is beneficial more so if a person has any side effects like gastrointestinal disturbances if plain metformin is taken. Both are fine. Thanks.
