Aceclofenac: Uses, Side Effects, Dosage, Precautions & More



Aceclofenac belongs to the category of non-steroidal anti-inflammatory drugs (NSAIDs). This medicine is prescribed in cases of chronic inflammation and pain in the bones and/or joints. Aceclofenac acts by blocking the effects of the enzyme known as "Cyclooxygenase (COX)" in the body. This enzyme releases chemical prostaglandins at the site of an injury and results in swelling, pain, and inflammation. By blocking the COX enzyme, Aceclofenac helps relieve pain and reduce inflammation.
