Treatment of abacterial prostato-vesiculitis with nimesulide

The efficacy and tolerability of nimesulide were assessed in the treatment of patients with prostato-vesiculitis. In a noncomparative investigation, 30 patients received oral nimesulide 100mg twice daily for three 10-day cycles. Micturition-related symptoms were resolved in 20 patients and clear amelioration of inflammatory signs was observed with transrectal ultrasound in 16 patients. Abnormal sperm forms decreased from 57 to 49% (p < 0.001). In a comparative investigation, 40 patients received nimesulide 200mg twice daily or ketoprofen 100mg twice daily via the rectal route. Patients and physicians expressed an overall opinion on efficacy in favour of nimesulide. In a pharmacokinetic study of healthy volunteers who received oral nimesulide 100mg as a single dose, the mean maximum nimesulide concentration (0.58 +/- 0.13 mg/L) in seminal fluid was achieved after 2 hours while the maximum seminal fluid: blood plasma ratio 0.32 +/- 0.02 was observed after 4 hours. These data suggest that nimesulide is an effective NSAID in the treatment of abacterial prostato-vesiculitis and also demonstrate that this drug has a favourable disposition within the genital tract.
