1. What Aceclofenac Tablets is and what it is used for

Aceclofenac Tablets belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). They have anti-inflammatory and painkiller properties causing a lowering of swelling, redness (inflammation) and pain. The medicine/active ingredient of Aceclofenac Tablets is aceclofenac.
