Mugel Local Oral Gel is a combination of three medicines. Choline Salicylate, Benzalkonium Chloride and Lidocaine. Choline Salicylate is a non-steroidal anti-inflammatory drug (NSAID). It works by blocking the release of certain chemical messengers (prostaglandins) which cause pain and inflammation (redness and swelling). Lidocaine is a local anesthetic. It works by blocking pain signals from the nerves to the brain which decreases the pain sensation. Benzalkonium Chloride is an antiseptic and disinfectant that cures superficial infections of the mouth.
