Brief summary
To assess the pharamcodynamic effects of coadministrated SK3530(PDE5 inhibitor) and tamsulosin, phase I study in healthy volunteers was designed.
Detailed description
During each of the two periods of a randomized, double-blind, placebo-controlled, crossover study, 16 healthy men received tamsulosin 0.2 mg daily for 7 days and either a single 100 mg of SK3530 or placebo on day7. The blood pressure and heart rate were monitored before and for 24 hours after SK3530 or placebo.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Maximal decrease from baseline in supine SBP | within 6 hrs after SK3530 or placebo |
Secondary
| Measure | Time frame |
|---|---|
| Incidence of postural hypotension | within 6 hrs after SK3530 or placebo |
| Maximal decrease from baseline in standing SBP, supine/standing DBP & HR | within 6 hrs after SK3530 or placebo |
| Outlier analysis: i) Standing/supine SBP < 85 mmHg, DBP < 45 mmHg; ii) Change in standing/supine SBP > 30 mmHg, DBP > 20 mmHg | within 6 hrs after SK3530 or placebo |
