This page lists brands whose active-ingredient set is exactly the combination below. It is identity information only — a fixed-dose combination is not the same product as its single ingredients, and the brand names are not interchangeable across markets.

Not medical advice. Check the pack and the exact composition before comparing products; ask a pharmacist if unsure.
