**Benoxonium Chloride + Lidocaine** is a combination medication commonly used for the relief of pain, irritation, and infection in the mouth and throat. Benzoxonium chloride acts as an antiseptic that helps kill or inhibit the growth of bacteria and other microorganisms, while lidocaine is a local anesthetic that temporarily numbs the affected area to reduce pain and discomfort. This combination is often found in lozenges, sprays, or topical preparations used to manage sore throat, minor oral infections, and inflammation of the mucous membranes.
