Trimethoprim (lactate), 1g

Trimethoprim (lactate) is an antifolate antibacterial agent that inhibits bacterial dihydrofolate reductase (DHFR), an essential enzyme responsible for the production of tetrahydrofolic acid (THF). By blocking this enzyme, trimethoprim prevents the synthesis of bacterial DNA, hindering bacterial survival. It is a standard antibiotic for treating urinary tract infections (UTIs).
