Trimethoprim is an antifolate antibacterial agent that inhibits bacterial dihydrofolate reductase (DHFR), a critical enzyme that catalyzes the formation of tetrahydrofolic acid (THF) - in doing so, it prevents the synthesis of bacterial DNA and ultimately continued bacterial survival.[L11893] Trimethoprim is often used in combination with [sulfamethoxazole] due to their complementary and synergistic mechanisms but may be used as a monotherapy in the treatment and/or prophylaxis of urinary tract infections.[L11893,L11830] It is structurally and chemically related to [pyrimethamine], another antifolate antimicrobial used in the treatment of plasmodial infections.[T707]

Indication
As a monotherapy, trimethoprim is indicated for the treatment of acute episodes of uncomplicated urinary tract infections caused by susceptible bacteria, including _E. coli._, _K. pneumoniae_, _Enterobacter spp._, _P. mirabilis_, and coagulase-negative _Staphylococcus_ species.[L11893,L11890] In various formulations in combination with [sulfamethoxazole], trimethoprim is indicated for the following infections caused by bacteria with documented susceptibility: urinary tract infections, acute otitis media in pediatric patients (when clinically indicated), acute exacerbations of chronic bronchitis in adults, enteritis caused by susceptible _Shigella_, prophylaxis and treatment of _Pneumocystis jiroveci_ pneumonia, and travelers' diarrhea caused by enterotoxigenic _E. coli_.[L11830,L11863] Trimethoprim is available as an ophthalmic solution in combination with [polymyxin B] for the treatment of acute bacterial conjunctivitis, blepharitis, and blepharoconjunctivitis caused by susceptible bacteria.[L11887]
