Udenafil: It blocks the action of the phosphodiesterase type-5 (PDE-5) enzyme. PDE-5 breaks down the cGMP that is responsible for relaxing the smooth muscles in the penis. After muscles are relaxed more blood is allowed into the penis tissues causing an erection.

In the penis, lungs, and retina are found high levels of PDE-5 enzyme. Your doctor may prescribe Zudena 100 mg to treat other health conditions such as benign prostatic hyperplasia (BPH) and pulmonary arterial hypertension (PAH).
