Trimethoprim is a bactericidal dihydrofolate reductase inhibitor. Trimethoprim prevents bacteria from taking up folic acid which is used to synthesize the essential DNA nucleotide thymine.
TOKU-E offers two forms of trimethoprim: trimethoprim (T011) and trimethoprim lactate (T012). Trimethoprim is slightly soluble in aqueous solution (12.1 mg/mL). Trimethoprim lactate is freely soluble in aqueous solution (19.6 mg/mL).

Trimethoprim acts by interfering with the action of bacterial dihydrofolate reductase, inhibiting synthesis of tetrahydrofolic acid. Tetrahydrofolic acid is an essential precursor in the de novo synthesis of the intermediate Thymidine monophosphate (dTMP), precursor of DNA metabolite Thymidine triphosphate.
