title: Concentration of pefloxacine in split ejaculates of patients with chronic male accessory gland infection.
abstract: The concentrations of pefloxacine and its N-demethylated derivative were measured in split ejaculates of 12 patients with chronic male accessory gland infection during treatment with 400 mg. pefloxacine twice a day. The mean concentrations of pefloxacine and N-demethylated pefloxacine (mg. per l.) were 8.7 +/- 1.2 (standard error of the mean) and 4.2 +/- 0.7 in fraction 1, and 9.8 +/- 1.1 and 4.3 +/- 0.6 in fraction 2. The concentrations in both fractions were correlated strongly (r equals 0.97). The concentration of pefloxacine in the secretory fluids of the prostate and seminal vesicles are 30-fold the minimal inhibitory concentration 90 of Escherichia coli and Klebsiella species, 100-fold the minimal inhibitory concentration 90 of Proteus mirabilis and equal to the minimal inhibitory concentration 90 of Streptococcus faecalis. In three-fourths of the patients signs of infection resolved after 4 weeks of treatment.
