Brief Summary

The purpose of this study is to evaluate the safety and pharmacokinetics/pharmacodynamics of co-administration of Clomipramine HCl 15mg and Sildenafil citrate 100mg compared to the effects after single oral administration in Korean healthy male volunteers.

Detailed Description

Clomipramine is a dibenzazepine-derivative tricyclic antidepressant (TCA) and is a potent inhibitor of serotonin and norepinephrine reuptake. Clomipramine may be used in a variety of indications. Condencia Tab contains low dose of 15mg of clomipramine HCl as an active ingredient, which is newly approved to market for the treatment of premature ejaculation.

This study is a prospective, randomised, open-labeled, 6-sequence, 3-period, 3-treatment, crossover, and single-center clinical trial. A total of 30 healthy male volunteers will be enrolled and randomised into one among 6 groups (5 subjects per a group). The safety and PK/PD characteristics of co-administration of Clomipramine HCl and Sildenafil citrate will be investigated closely compared to the effects after single dose administrations.

Secondary Outcome Measures
NameTimeMethod
Adverse eventsFor 3 Weeks after dosing
Pharmacokinetic parameters except the primary endpointsFrom Day 1(dosng) to Day 4(72hrs)

Including Tmax, T1/2, AUCnorm, Cmax norm, CL/f and Cmax/AUC

The maximum change of systolic blood pressures within 12hrs after dosingDay 1(dosing) to Day 2(12hrs)

At supine and upright positions

The maximum change of dystolic blood pressure within 12hrs after dosingFrom Day 1(dosing) to Day 2(12hrs)

at supine and upright positions

The maximum change of heart rates within 12 hours after dosingFrom Day 1(dosing) to Day 2(12hrs)

At supine and upright positions

The rate of the subjects who experienced the clinically significant change of blood pressuresFrom Day 1(dosing) to Days 2(12hrs)
