Avana 100 Mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which is responsible for regulating blood flow in the penis. By blocking PDE5, Avana 100 Mg allows for increased blood flow, which is essential for achieving an erection during sexual arousal. One of the key advantages of Avana 100 Mg is its rapid onset; it typically begins working within 15 to 30 minutes, and its effects can last for up to six hours. This makes it a convenient option for those seeking a fast-acting and reliable solution for ED.
