Zenegra is a generic Sildenafil-containing medicine intended for use in urology – for the most part in the treatment of erectile dysfunctions of different origin. The drug provides regulation of the enzymic activity of the specific phosphodiesterase and releases nitric oxide that provides the muscle-relaxing effect. The active ingredient also maintains a certain level of blood pressure in the penis, providing a proper erectile response. The usual effect lasts no less than 4 hours; however, some patients report 18 and more hours of increased sexual arousal.

Zudena is another representative of the PDE5 inhibitors ubiquitously used in contemporary urology. It is commonly used for the therapy and prevention of erectile dysfunction. The pills contain udenafil – a reverse inhibitor of the phosphodiesterase-5, which is responsible for filling the penis with blood. This active ingredient has a range of recently introduced advantages the most notable of which are more rapid absorption (30-60 minutes) and increased half-life (starting from 10 to 12 hours, which leads to a 24-hour period of activity). The medicine may be prescribed not only for symptomatic but also for a long-term treatment.
