Taking a 5mg dose of tadalafil, the active component in Cialis, has demonstrated its effectiveness in treating erectile dysfunction (E.D.), even in individuals who have previously had limited success with other E.D. medications. This phosphodiesterase type 5 inhibitor has received approval from the Food and Drug Administration (FDA) for addressing both erectile dysfunction and the signs and symptoms associated with benign prostatic hyperplasia (BPH). Its mechanism of action involves enhancing blood flow to the penis, facilitating the attainment and maintenance of an erection. What sets tadalafil apart is its extended duration of action, ensuring that it remains within your system, ready to respond when the need arises.
