Udenafil
Udenafil (pronounced: yoo-DEN-uh-fil) is a phosphodiesterase type 5 inhibitor (PDE5 inhibitor) used in the treatment of erectile dysfunction (ED). It is marketed under the brand name Zydena.
Etymology
The term "Udenafil" is a combination of the prefix "Udena-" (from the brand name Zydena) and the suffix "-fil" (common to other PDE5 inhibitors).
Pharmacology
Udenafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is found primarily in the penis's corpus cavernosum, and also in the pulmonary artery. Inhibition of this enzyme results in the dilation of blood vessels in the penis, thereby enhancing erection.
Indications
Udenafil is indicated for the treatment of erectile dysfunction. It may also be used in the treatment of pulmonary hypertension, although this is less common.
Side Effects
Common side effects of Udenafil include headache, flushing, dyspepsia, and nasal congestion. Less common side effects may include back pain, myalgia, and visual disturbances.
Contraindications
Udenafil should not be used by individuals with a known hypersensitivity to the drug, or by those using nitrate medications, as this can result in a severe and potentially fatal drop in blood pressure.
