Trimethoprim is a broad-spectrum antibacterial agent primarily used to treat bacterial infections of the urinary tract, respiratory system, and gastrointestinal tract. It acts as a dihydrofolate reductase inhibitor, preventing bacterial DNA synthesis and replication, making it highly effective against both Gram-positive and Gram-negative organisms.

At Bluepill Express, we manufacture and export Trimethoprim Active Pharmaceutical Ingredient (API) with superior purity, consistent assay values, and compliance with international pharmacopeial standards — including IP, BP, USP, and EP. Our manufacturing facilities are WHO-GMP, ISO, and cGMP-certified, ensuring global-standard quality suitable for regulated and semi-regulated markets.

Trimethoprim is often formulated alone or in combination with Sulfamethoxazole (as Co-trimoxazole) for enhanced antibacterial efficacy. The API exhibits excellent stability, uniform particle size distribution, and high solubility for versatile pharmaceutical applications.

Therapeutic Applications:

• Urinary Tract Infections (UTIs)
• Respiratory Tract Infections (RTIs)
• Gastrointestinal Bacterial Infections
• Skin and Soft Tissue Infections
• Prophylaxis and treatment of Pneumocystis jirovecii pneumonia (PCP)

Mechanism of Action:

Trimethoprim selectively inhibits bacterial dihydrofolate reductase (DHFR) — an enzyme crucial for the synthesis of tetrahydrofolic acid, a component required for bacterial DNA and protein synthesis. This inhibition stops bacterial growth, providing bacteriostatic action.
