About Co-trimoxazole (Sulfamethoxazole/Trimethoprim)

Co-trimoxazole, universally known in Nigeria as Septrin, is arguably the single most self-medicated drug in the country. Walk into any patent medicine store from Mushin to Maiduguri, from Aba to Abeokuta, and you will find Septrin prominently displayed. It is a combination antibiotic containing two active ingredients — sulfamethoxazole and trimethoprim — that work together to block two consecutive steps in the bacterial production of folic acid, a nutrient essential for bacterial growth and survival. By attacking bacteria at two different points in the same metabolic pathway, co-trimoxazole achieves a synergistic bactericidal effect that is more potent than either component alone.
