The concentration of doxycycline in human prostate gland and its role in the treatment of prostatitis.
The concentrations of doxycycline were measured in 36 enucleated, enlarged prostate glands. After administration of 200 mg of doxycycline intravenously significant tissue concentrations (mean value 1.79 mug/g) were rapidly obtained. The mean concentration of the drug 14 hours after a repeated oral dose of 100 mg was 1.56 mug/g. The ratios of tissue and serum concentrations were 0.610 and 0.568, respectively. As there are only a few antibiotics which penetrate into the prostate, the importance of these data for the treatment of bacterial or mycoplasma prostatitis is obvious.
