CLINICAL PHARMACOLOGY
Trimethoprim is a synthetic antibacterial drug active against a wide
variety of aerobic
gram-positive and gram-negative ophthalmic pathogens. Trimethoprim
blocks the
production of tetrahydrofolic acid from dihydrofolic acid by binding
to and reversibly
inhibiting the enzyme dihydrofolate reductase. This binding is
stronger for the bacterial
enzyme than for the corresponding mammalian enzyme and therefore
selectively
interferes with bacterial biosynthesis of nucleic acids and proteins.
Polymyxin B, a cyclic lipopeptide antibiotic, is bactericidal for a
variety of gram-negative
organisms, especially _Pseudomonas aeruginosa_. It increases the
permeability of t
