Avana 100 mg is a medication containing avanafil, which is primarily used to treat erectile dysfunction (ED) in men. Avanafil belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors, similar to sildenafil (Viagra), tadalafil (Cialis), and vardenafil (Levitra). Avanafil works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for the degradation of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the corpus cavernosum of the penis. By blocking PDE5, avanafil increases the levels of cGMP, leading to smooth muscle relaxation and vasodilation, which allows for increased blood flow to the penis during stimulation, resulting in an erection.
