Levitra (Vardenafil) is a drug administered for the use of erectile disfunction. Erectile disfunction is when a man is unable to sustain an erection. The cause of erectile dysfunction is when the arteries don’t carry enough blood to the penis due to a narrow opening. Levitra increases blood flow to the genitals when a man is sexually aroused by relaxing the arteries which produces The ingredient in the medication works on the chain of reactions within the penis during arousal which triggers nitric oxide which then causes an enzyme, guanylate cyclase, to produce (CMGP) cyclic guanosine monophosphate. CMGP is a regulator of the contraction ,expansion and dilation of blood vessels that carry blood to the penis. After CMGP is no longer working the blood vessels return to normal size ending the erection, levitra works by inhibiting cgmp for the longer therefore making the erection last longer. Levitra is a small round orange pill engraved with the words “20”. Generic Levitra is available in tablets of 2.5 milligrams (mg), 5 mg, 10 mg, and 20 mg. The first dose is usually 10 mg.A 10-mg dose of levitra is approximately equivalent to 50 mg of sildenafil, or Viagra. This is because the chemical composition of levitra is very different from that of sildenafil which is another male enhancement drug. Levitra should be taken 30-60 minutes before sex and a maximum of one tablet can be taken every 24 hours.The drug will not work unless the man is sexually aroused, so foreplay is a necessity.
Levitra 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.

Grapefruit juice contains a chemical that makes adverse effects more likely, so it should not be consumed while using Levitra. Levitra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Viagra or other drugs similar to vardenafil. Most of these people also had certain pre-existing eye problems or risk factors for blood vessel disorders (such as heart disease, diabetes, high blood pressure, high cholesterol, coronary artery disease, smoking, or being over 50 years old).
