Levitra is a class of PDE-5 inhibitors which treats erectile dysfunction or impotence in men. Impotence is a physical condition when a man is unable to get or sustain an erection. Even if he gets an erection; it is not firm enough to go for a sexual intercourse. It usually happens because the arteries that carry the blood to the penis are too narrow as a result there is no blood flow to the penile nerve. Vardenafil increases blood flow to the penis and helps to make a firm erection.
Active ingredient- Vardenafil HC1
Other Ingredients- polyethylene glycol, hypromellose, magnesium stearate, colloidal silicon dioxide, titanium dioxide, yellow ferric oxide, red ferric oxide microcrystalline cellulose and crospovidone
Levitra (Vardenafil) belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor stops PDE5 from constricting the arteries. The other competitors of this class are- Viagra and Cialis
By relaxing the arteries, the ED pill enhances blood flow when a man is sexually aroused. The active ingredient works on the chain of reactions within the penis during arousal. When a male is sexually aroused, nitric oxide is released into his penis, and this triggers a chain of reactions. This causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP).
cGMP regulates the contraction and dilation, or expansion, of blood vessels that carry blood to and from the penis. The chemical reaction causes the vessels that supply the penis to dilate, while those removing blood from the penis contract.Phosphodiesterase-5 (PDE5), another enzyme breaks down or destroys cGMP.
When cGMP is destroyed, the blood vessels return to their normal size, effectively ending the erection. Vardenafil stops PDE5 from destroying cGMP. In this way, it allows cGMP to work for longer. As a result, it helps prolong an erection. The ED pill can only work effectively when a person is sexually stimulated or excited.
