zudena 100 mg tablet, with udenafil as its active ingredient as well. Research has shown that udenafil significantly enhances erectile function in patients with erectile dysfunction (ED), particularly those who have hypertension and are on antihypertensive medications. 

Zudena (udenafil) works by preventing the release of an enzyme known as phosphodiesterase type 5 (PDE5), thereby stopping the breakdown of cyclic Guanosine Monophosphate. Zudena aids the body in releasing nitric oxide, a substance that enhances blood circulation throughout the system, including the penile organ, thanks to this mechanism of action.
