Influence of alcohol on the hemodynamic effects and pharmacokinetic properties of mirodenafil: a single-dose, randomized-sequence, open-label, crossover study in healthy male volunteers in Korea.

Abstract：

BACKGROUND:Mirodenafil is a phosphodiesterase type 5 (PDE-5) inhibitor developed for the treatment of erectile dysfunction. Mirodenafil has the possibility of being administered with alcohol. OBJECTIVE:This study assessed the hemodynamic effects and pharmacokinetic properties of mirodenafil administered with alcohol. METHODS:This single-dose, randomized-sequence, open-label, crossover study was conducted in healthy male volunteers at the Clinical Trials Center, Seoul National University Hospital, Seoul, Korea. Volunteers were randomly allocated to 1 of 3 randomized-sequence groups, each of which consisted of 3 administration phases, each separated by a 1-week washout period: oral mirodenafil 100 mg, alcohol 0.5 g/kg, and both. Vital signs (systolic blood pressure [SBP], dia-stolic BP [DBP], and pulse rate) were measured before (baseline) and at 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12, and 24 hours after administration. Because volunteers were given a standardized meal at 4 hours after mirodenafil and/or alcohol administration, hemody-namic results were assessed using the maximum decrease from baseline during a period of up to 4 hours after administration. For pharmacokinetic assessment, serial blood samples were collected before (baseline) and at 0.5, 1, 1.25, 1.5, 2, 2.5, 3, 4, 6, 8, 12, and 24 hours after administration. Tolerability was assessed using monitoring of adverse events (AEs), clinical laboratory parameters, and results of 12-lead electrocardiography. RESULTS:A total of 20 subjects participated in the study (mean [range] age, 25.5 years [20-41 years]; weight, 69.8 kg [57.4-87.2 kg]; and height, 174.7 cm [168-186 cm]). Up to 4 hours after the administration of mirodenafil, alcohol, and mirodenafil + alcohol, the mean (SD) maximum decreases in SBP were 8.5 (3.5), 13.5 (7.8), and 15.1 (6.7) mm Hg, respectively, and the maximum decreases in DBP were 6.4 (4.8), 13.3 (7.4), and 13.8 (5.2) mm Hg. Simultaneous administration of mirodenafil + alcohol was associated with additional mean (95% CI) decreases in SBP and DBP of 1.7 mm Hg (-6.0 to 2.6 mm Hg) and 0.6 mm Hg (-4.7 to 3.6 mm Hg) compared with alcohol alone. Pharmacokinetic parameters of mirodenafil were not significantly different when the drug was administered with or without alcohol. The mean (SD) AUC(0-t) values were 842.0 (434.7) ng/mL/h with mirodenafil and 833.4 (398.2) ng/mL/h with mirodenafil + alcohol. The most common AEs considered at least possibly related to study drug were nasal congestion (7 subjects [35%]), headache (3 [15%]), nausea (1 [5%]), and hiccups (1 [5%]). CONCLUSIONS:The concurrent administration of mirodenafil with alcohol was not associated with clinically significant hemodynamic changes in these healthy male volunteers in Korea. The pharmacoki-netics of mirodenafil were not significantly altered by this concurrent administration. Mirodenafil administered with alcohol had a tolerability profile comparable to that of mirodenafil alone.
