Sildenafil

Sildenafil is a clinically validated phosphodiesterase type 5 (PDE5) inhibitor developed to treat erectile dysfunction. By selectively inhibiting PDE5, sildenafil enhances blood flow to support consistent erectile function during sexual stimulation. Effective within 30-60 minutes and lasting up to 4-6 hours, it provides a reliable solution for men seeking to regain sexual confidence.
