By relaxing the arteries, vardenafil 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.
When should I seek urgent medical help?
The chemical reaction causes the vessels that supply the penis to dilate, while buy levitra fast 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. In this way, it allows cGMP to work for longer. As a result, it helps prolong an erection.

The first dose is normally 10 mg. No more than one tablet should be taken in 24 hours. A 10-mg dose of vardenafil is approximately equivalent to 50 mg of sildenafil, or Viagra. This is because the chemical composition of vardenafil is different from that of sildenafil. Vardenafil is taken 25 to 60 minutes before sex.

Products related to Levitra 60 Mg
Vilitra tablets which contain Vardenafil 10mg-60mg acts on the erectile tissue of the penis to increase blood flow which causes an erection. During sexual stimulation nitric oxide is released in the erectile tissue of the penis which activates the enzyme guanylate cyclase. This enzyme increases levels of a chemical called cyclic guanosine monophosphate (cGMP), which relaxes the blood vessels in the penis and allows blood to fill the spongy erectile tissues to cause an erection. Another enzyme called phosphodiesterase type 5 (PDE5) breaks down cGMP preventing blood flow into the penis, which causes loss of an erection. Vilitra Vardenafil tablets 10mg-60mg inhibit the action of PDE5 which resolves erectile dysfunction by allowing the natural process of sexual stimulation to activate the cGMP mechanism for achieving and maintaining an erection.
What should I tell my healthcare provider before taking vardenafil?
Vilitra Vardenafil tablets 10mg-60mg should be taken within an hour of planned sex and in most cases, it helps you to get an erection in about 30 minutes that will last for around 4 hours, provided you are sexually excited. Vilitra Vardenafil tablets 10mg-60mg contain the active ingredient vardenafil, which resolves erectile dysfunction (impotence) in men, by increasing blood flow into the penis. Vilitra Vardenafil tablets 10mg-60mg contain vardenafil, a phosphodiesterase type 5 (PDE5) inhibitor, used to treat erectile dysfunction in men (impotence). When taken before planned sexual activity, Vilitra Vardenafil tablets 10mg-60mg (generic Levitra) inhibit the breakdown (by the enzyme PDE5) of a chemical called cGMP, produced in the erectile tissue of the penis during sexual arousal, and this action allows blood flow into the penis causing an erection. The most commonly reported side effects when taking Vilitra and Levitra tablets 10mg – 60mg include, headache, dizziness or light-headedness, flushing, nasal congestion, dyspepsia (heartburn), nausea.

Erectile dysfunction is when a man is unable to get or sustain an erection. It usually happens because the arteries that carry the blood to the penis are too narrow. Vardenafil increases blood flow to the penis. Its action is similar to that of sildenafil, or Viagra, but Viagra lasts between 2 and 4 hours, while Levitra lasts 4 hours. During a penile erection, the penis fills with blood.
Drugs Interactions
The blood vessels that supply the penis with blood expand, or dilate, and the vessels that take blood away from the penis contract. The two large chambers in the penis, known as the corpus cavernosa, fill with blood. As the blood accumulates in the penis, an erection results. Vardenafil belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor stops PDE5 from constricting the arteries.

Pharmacokinetics and Administration
The effect lasts for up to 5 hours. A maximum of one tablet can be used every 24 hours. The drug will not work unless the man is sexually aroused, so foreplay will normally be necessary. Vardenafil can be taken with or without food, but drinking alcohol is not advised, as it reduces the chance of getting an erection. Alcohol can also increase the risk of adverse effects.
