How Oronac RB Tablet works

Oronac RB Tablet is a combination of two medicines: Diclofenac and Rabeprazole which relieve pain. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) which works by blocking the release of certain chemical messengers that cause pain, fever and inflammation (redness and swelling). Rabeprazole is a proton-pump inhibitor which prevents damage to the stomach lining caused by Diclofenac.
