Trimethoprim

Trimethoprim is a synthetic antibacterial agent that functions as a folate antagonist and dihydrofolate reductase inhibitor While often referred to in clinical reference tools as its own class or subclass, it represents a specific active pharmaceutical ingredient within the broader antifolate class

Trimethoprim is a synthetic antibacterial agent that functions as a folate antagonist and dihydrofolate reductase inhibitor Mechanistically, it selectively and reversibly inhibits bacterial dihydrofolate reductase, preventing the conversion of dihydrofolic acid to active tetrahydrofolic acid and consequently halting essential bacterial nucleic acid and protein synthesis
