title: The concentration of sulphamethoxazole and trimethoprim in human prostate gland.
abstract: Sulphamethoxazole and trimethoprim concentrations were measured in 19 enucleated human prostate glands. Good concentrations of sulphamethoxazole were found after 4 days of treatment: the ratio of plasma concentration to that of prostate varied from 1-25 to 3-29. The trimethoprim concentrations were 2 to 3 times higher in the prostate than in the plasma. These high concentrations were reached very rapidly after the first dose of trimethoprim. The results are compared with date from the literature. The combination sulphamethoxazole-trimethoprim should be of value in the treatment of bacterial prostatitis.
