title: Pharmacokinetics of miconazole in serum and exudate of pelvic retroperitoneal space after radical hysterectomy and pelvic lymphadenectomy.
abstract: Due to the increased number of compromised hosts with fungal infections, doctors have recently started prescribing antifungal agents. In the field of gynecology, however, the choice of which drug to use has been difficult. The efficacies of these drugs depend on their antifungal spectra, potencies and concentrations in tissues. The present study was designed to investigate the pharmacokinetics of miconazole in the exudate of the retroperitoneal space that is formed after radical hysterectomy and pelvic lymphadenectomy. A total of 600 mg of miconazole was administered to the patients for exactly 60 min using an automatic drip-infusion pump. The parameters of the formulas analyzed by the two-compartment model were determined using the least-squares method, and a simulation curve was made. The maximum drug concentration (Cmax) of miconazole in serum was 6.26 mg/l 1 h after drip infusion commencement and the t1/2 in serum was 8.86 h. The value of the area under the time-serum concentration curve (AUC) in serum was 19.13 mg/h per l. The Cmax of miconazole in the exudate of the retroperitoneal space was 0.13 mg/l 2.48 h after the drip infusion was started. The value of AUC in the exudate was 2.52 mg/h per l.
