Working on Zenegra Red 100 mg medication

Zenegra Red, a 100 mg tablet, is a medication used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, which helps to achieve and maintain an erection.

Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. PDE5 is an enzyme responsible for breaking down cyclic guanosine monophosphate (cGMP), an essential chemical for dilating and relaxing blood vessels in the penis.

When a man is sexually stimulated, the nerves in the penis release nitric oxide, which stimulates cGMP production. This causes the smooth muscles in the penis to relax, allowing more blood to flow into the penis and resulting in an erection.

Sildenafil works by inhibiting the action of PDE5, which increases the cGMP levels in the penis. This leads to enhanced dilation and relaxation of blood vessels in the penis, allowing more blood to flow into the penis during sexual stimulation and resulting in an erection.
