Sulfamethoxazole / Trimethoprim Suspension Suppliers & Bulk Manufacturers

Sulfamethoxazole / Trimethoprim Suspension is a combination antibiotic used to treat a variety of bacterial infections in patients who cannot swallow tablets. It is commonly prescribed for respiratory tract infections, urinary tract infections (UTIs), acute otitis media, traveler's diarrhea, and certain skin and soft tissue infections. The suspension allows for accurate pediatric dosing and easier administration.

This suspension contains two active ingredients: sulfamethoxazole, a sulfonamide antibiotic that inhibits bacterial folic acid synthesis, and trimethoprim, a dihydrofolate reductase inhibitor that enhances the antibacterial effect.
