100mg Viagra, or sildenafil, primarily targets an enzyme called phosphodiesterase-5 (PDE5). PDE5 breaks down cGMP, a crucial molecule involved in achieving and maintaining an erection. By inhibiting PDE5, Viagra increases cGMP levels.
Increased cGMP: The Key to Erection
Higher cGMP levels relax the smooth muscles in the blood vessels of the penis. This relaxation allows increased blood flow into the penis, causing it to become engorged and erect. The effect is triggered by sexual stimulation; Viagra doesn’t cause erections on its own.
The 100mg dose provides a higher concentration of sildenafil in the bloodstream compared to lower doses. This can lead to a more pronounced effect, but it’s important to follow your doctor’s instructions. Individual responses vary, so it’s crucial to discuss any concerns with your physician.
The body metabolizes and eliminates sildenafil over several hours, so the effects are temporary. Always consult your doctor before taking Viagra or any other medication for erectile dysfunction, and report any side effects promptly.
