Tadalafil and sildenafil are both phosphodiesterase type‑5 (PDE5) inhibitors, primarily used to treat erectile dysfunction (ED) in men.
Both drugs inhibit PDE5, preventing the breakdown of cGMP, which leads to smooth muscle relaxation and increased blood flow in the penis—but only when there’s sexual stimulation.
