phenylephrine-hydrochloride and Erectile-Dysfunction

To investigate the influence of nasal continual positive airway pressure (nCPAP) on the erectile function of erectile dysfunction (ED) patients with obstructive sleep apnea syndrome(OSAS).. Twenty-seven patients with ED and OSAS were randomly divided into treatment (n = 15) and control (n = 12) groups, the former treated by nCPAP from 22:00 to 6:00 per night for 1 month. And the apnea-hypopnea index(AHI), the lowest oxygen saturation (SaO2) and IIEF were compared before and after treatment.. AHI, the lowest SaO2, erectile function and IIEF showed no significant difference before treatment in the two groups, but displayed a significant improvement after treatment in the treated group compared with the control (P > 0.05), in which no significant changes were observed before and after treatment (P > 0.05).. nCPAP therapy can improve the erectile function of ED patients with OSAS.

Sildenafil citrate (Viagra) has been shown to be an effective treatment for erectile dysfunction. Initial studies reported a high tolerability and low incidence of certain characteristic adverse reactions. We sought to evaluate the incidence of side effects of sildenafil citrate, independent of industry support and constraints, utilizing a heterogeneous cohort of patients from a university-based practice.. A prospective, open-label, flexible-dose study of 256 patients treated with sildenafil citrate for erectile dysfunction was performed at a single institution. The patients were questioned explicitly about the occurrence of headache, flushing, dyspepsia, nasal congestion, visual changes, and other side effects.. The adverse reactions most commonly observed were flushing (30.8%), headache (25. 4%), nasal congestion (18.7%), and heartburn (10.5%). All events were short lived and mild in nature. In the present study, 31.6% of patients experienced one or more adverse events. However, no one withdrew from the study because of the severity of these events. There was a significant association between higher doses and the occurrence of side effects.. The incidence of adverse events attributable to sildenafil citrate may be higher than initially reported, but an explanation may be the methodology of data collection and the industry-independent nature of this study. The side-effect profile is dose related and mild. Sildenafil citrate remains a safe and well-tolerated treatment for erectile dysfunction.
