The disposition of [14C]finasteride, a competitive inhibitor of steroid 5 alpha-reductase, was investigated after oral administration of 38.1 mg (18.4 microCi) of drug in six healthy volunteers. Plasma, urine, and feces were collected for 7 days and assayed for total radioactivity. Concentrations of finasteride and its neutral metabolite,(More)
The effects of the 5 alpha-reductase inhibitor, finasteride, on scalp skin testosterone (T) and dihydrotestosterone (DHT) levels were studied in patients with male pattern baldness. In a double blind study, male patients undergoing hair transplantation were treated with oral finasteride (5 mg/day) or placebo for 28 days. Scalp skin biopsies were obtained(More)
A single-blind study was conducted to investigate the effect of multiple doses of finasteride, a 5 alpha-reductase inhibitor for the treatment of benign prostatic hyperplasia, on the single-dose pharmacokinetics of antipyrine. Twelve patients with benign prostatic hyperplasia received a total of four single oral doses of 18 mg/kg antipyrine before, during,(More)
The Roux-en-Y gastric bypass is one of the most common operations for morbid obesity. Although rare, gastropulmonary fistulas are an important complication of this procedure. There is only one recently reported case of this complication. The present report describes the serious nature of this complication in a patient after an uneventful laparoscopic(More)
The influence of multiple doses of ofloxacin (ORF 18489) on the disposition of theophylline was studied in 15 male volunteers. Subjects were confined in the Clinical Research Unit for 13 days and given a xanthine-free diet. A single dose (3 mg/kg) of theophylline was given orally, and blood samples were collected at fixed time intervals for 36 h. The(More)
Plasma and suction skin blister fluid concentrations of ceftriaxone were studied in 12 subjects after intravenous administration of 1 g of ceftriaxone every 12 h (q12h) and 2 g every 24 h (q24h) after single and multiple doses. Ceftriaxone concentrations were determined by high-pressure liquid chromatography. Mean peak plasma concentrations (at the end of(More)
