The indicate profiles of your alter from baseline in standing systolic blood pressure in subjects handled with doxazosin in combination with 25 mg VIAGRA or matching placebo are proven in Determine two.
There were no experiences of syncope amid these people. For these four topics, the placebo-subtracted mean most decreases from baseline in supine and standing systolic blood pressures have been 14.8 mmHg and 21.5 mmHg, respectively. Two of these topics had a standing SBP < 85mmHg. Both equally of those subjects had been protocol violators, just one because of a very low baseline standing SBP, and the opposite as a consequence of baseline orthostatic hypotension.

Figure six displays that whatever the baseline levels of functionality, subsequent operate in patients dealt with get more info with VIAGRA was better than that witnessed in people taken care of with placebo. Concurrently, on-treatment operate was improved in treated people who have been fewer impaired at baseline.
