How ED (Sildenafil 100mg) Work
Most ED medications are known as phosphodiesterase type 5 inhibitors (PDE5 inhibitors). These drugs work by enhancing the natural process of erectile function. Under normal circumstances, sexual arousal triggers the release of nitric oxide in the penis, which relaxes the blood vessels and allows increased blood flow to the area.
PDE5 inhibitors help by blocking an enzyme (phosphodiesterase type 5) that can limit this blood flow. By inhibiting this enzyme, the medications promote better blood flow, leading to an erection when combined with sexual stimulation.
