CHOLINE SALICYLATE+LIGNOCAINE is a combination of two medicines, namely: Choline salicylate and lidocaine. Choline salicylate is a non-steroidal anti-inflammatory drug (NSAID), whereas lidocaine is a local anesthetic. CHOLINE SALICYLATE+LIGNOCAINE is primarily used to treat mouth ulcers. Choline salicylate works by blocking the effect of a chemical messenger in your body, known as cyclo-oxygenase (COX) enzymes that make another chemical 'prostaglandins' (PG). These prostaglandins are produced at injury sites and cause pain and swelling. By blocking the effect of COX enzymes, lesser PGs are produced, which reduces mild to moderate pain and inflammation at the injured or damaged site. Lidocaine blocks the pain signals from the nerves to the brain, thereby helps in decreasing the pain sensations. Together, CHOLINE SALICYLATE+LIGNOCAINE helps in treating mouth ulcers.
