Avaforce (Avanafil) 100 mg is a medication used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, similar to sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). Avanafil works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain an erection. It does this by inhibiting the enzyme phosphodiesterase-5 (PDE5), which normally breaks down a substance called cyclic guanosine monophosphate (cGMP). By inhibiting PDE5, avanafil allows cGMP to accumulate, leading to relaxation of the smooth muscles in the penile blood vessels and increased blood flow to the penis. https://www.genericday.com/avaforce-100-mg.html
