Trimethoprim: A Synthetic Antibiotic Agent Inhibiting Dihydrofolate Reductase
Trimethoprim, a synthetic antibiotic agent, exerts antimicrobial activity by blocking the production of tetrahydrofolic acid from dihydrofolic acid by binding to and reversibly inhibiting the required enzyme, dihydrofolate reductase. Trimethoprim is active against a wide range of Gram-positive and Gram-negative aerobic bacteria. In addition, some combination agents with the other antimicrobials (e.g.: sulphamethoxazole [S0361], daptomycin [D4229] and polymyxin B [P1923]) are widely used for the treatment of infections including MRSA infection.
