Why take levitra? Although few men will actually admit to impotence, the truth is that it can strike anyone from time to time. There are various causes of impotence, some of which are permanent, while other can be temporary.

It is important to note that erectile dysfunction can be due to another condition, such as diabetes, high blood pressure, or high cholesterol, which may be undiagnosed, so before taking a drug such as Levitra, be sure to talk to your doctor.

Whether impotence is due to illness, stress, or another cause, levitra is one of a new generation of medications designed to affect a cure.

As with all strong and effective medications, there can be various side effects – the most common ones are headaches, flushing, and stuffy or runny nose.

The active ingredient in this medication is vardenafil, which is a phosphodiesterase type 5 inhibitor – it works by preventing the action of a chemical in the body called phosphodiesterase type 5.

Though we rarely think about it, achieving an erection is the result of a complex chain of events, which involves signals from the nervous system and the release of chemical messengers within the tissues of the penis. One of these chemical messengers is called cyclic GMP.

Cyclic GMP causes the blood vessels in the penis to widen, by relaxing a thin layer of muscle found in the blood vessel walls. When this happens, more blood can enter the penis, resulting in the penis becoming rigid and erect.

Vardenafil works to enhance the actions of the chemical messengers responsible for producing an erection, and thus can only work once these messengers are present – in other words, when you are aroused.

To be effective, take the medication around 25 minutes to one hour before intended intercourse – it can produce an erection in response to sexual stimulation up to five hours after you have taken it.
