The medication Zudena 100 mg Tablet (Udenafil) is used to treat erectile dysfunction, which is defined as the inability to develop or sustain a penile erection strong enough for fulfill sexual relations.
Although UDenafil, or Zudena-100, does not directly relax a cavernous body, it does, during sexual stimulation, increase the relaxing impact of nitric oxide by blocking PDE-5, the enzyme that breaks down cGMP in the cavernous body. An erection results from this relaxation of the artery's muscles and increased blood flow to the penis' tissues.
Udenafil, or Zudena-100, increases erection and increases the likelihood of having a good sexual encounter.
