Active Ingredients:
Co-trimoxazole (sulfamethoxazole and trimethoprim)
Therapeutic actions: Co-trimoxazole exhibits a synergistic antibacterial effect when compared to each of its components administered singly. This is because trimethoprim and sulfamethoxazole inhibit successive steps in the folate synthesis pathway.
Sulfamethoxazole acts as a false-substrate inhibitor of dihydropteroate synthetase. Sulfonamides such as sulfamethoxazole are analogues of p-aminobenzoic acid (PABA) and are competitive inhibitors of the enzyme; inhibiting the production of dihydropteroic acid.
Trimethoprim acts by interfering with the action of bacterial dihydrofolate reductase, inhibiting synthesis of tetrahydrofolic acid.
Indications: Co-trimoxazole is a combination of trimethoprim and sulfamethoxazole, a sulfa drug. It eliminates bacteria that cause various infections, including infections of the urinary tract, lungs (pneumonia), ears, and intestines.
