Trachoma: Its Treatment with a Long-Acting Sulfonamide Administered Orally

Abstract
Summary The oral administration of a long-acting sulfonamide, sulfamethoxypyridazine, is evaluated in the treatment of trachoma. Four courses of treatment at intervals of 5 days, each course consisting in the administration of 0.5 g once a day for 10 days, proved to cure confirmed cases of trachoma. Concomitant therapy with an antibiotic suspension applied locally produced rapid clinical improvement.
