During a penile erection, the penis is filled with blood. The blood vessels that supply blood to the penis expand or dilate, and the blood vessels that take the blood supply away from the penis contract. Corpus cavernosa, the large low chambers of the penis, fill with blood. And due to the accumulation of blood in the penis, an erection occurs.
Levitra generic is called vardenafil, and it belongs to a category of medications known as phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor is known for stopping PDE5 from constricting the arteries. This drug speeds up blood flow when a man is sexually aroused by relaxing the arteries.
The active ingredients of this drug work on the chain of reactions inside the penis during arousal. When a male is aroused, nitric oxide releases into his penis, which further triggers a chain of reactions causing an enzyme and guanylate cyclase to produce cyclic guanosine monophosphate (cGMP).
cGMP is known to regulate the contraction and expansion, or dilation, of blood vessels that carry blood through the penis. The chemical reaction is responsible for dilating blood vessels that supply the penis; during those extracting blood from the penis contract.
Phosphodiesterase-5 (PDE5) inhibitor is an enzyme that breaks down or destroys cGMP. After cGMP is destroyed, the vessels return to their normal size, safely and effectively ending the erection. Levitra stops PDE5 from destroying cGMP, allowing cGMP to function for longer. In this way, it helps prolong an erection for long-lasting sexual intercourse.
