Two lozenges containing benzocaine assessed in the relief of sore throat

A study has been conducted in general practice comparing two brands of lozenges, Merocaine (Merrell) and Tyrozets, (M.S.D.), in the management of acute sore throat and pharyngitis. Eighty-eight patients entered the between-patient study and each completed a diary card covering symptoms experienced and dosage used for each of the two drugs. The doctor reported upon the appearance of the throat and added antibiotics in cases of necessity, which was approximately for one-third of patients. Merocaine proved to be significantly superior to Tyrozets in producing rapid pain relief (within 15 minutes) and reduction of faucial and pharyngeal injection.
