If you’re wondering what Levitra is or how it can help you with men’s sexual function problems, this is the right place for you to be.  Levitra contains vardenafil, an active substance from a group of medicines called phosphodiesterase 5 inhibitors, which are used to treat erectile dysfunction in adult men, a condition that involves difficulty getting or maintaining an erection. At least one in ten men has trouble getting or keeping an erection at some point. This can be due to physical or psychological causes, or a mixture of both, so why not fight back with this Erectile dysfunction treatment medicine. Regardless of the cause, muscle and blood vessel abnormalities mean that there is not enough blood in the penis to get and keep an erection. Levitra will only work when you are sexually stimulated. This medicine reduces the action of a natural substance in the body that prevents an erection. The benefits of Levitra tablets allow you to get an erection long enough to maintain a satisfactory sexual relationship.

The way Levitra works is simple. When a man becomes sexually aroused, a series of reactions take place in the body. A chemical, cyclic guanosine monophosphate (or cGMP), causes the blood vessels in the penis to relax, widen, and allow more blood flow, leading to an erection. An enzyme called phosphodiesterase-5 (PDE5) can cause cGMP to dissolve, resulting in erectile dysfunction. Levitra inhibits the action of PDE5, making it easier to maintain an erection.

Now, depending on the person, Levitra can have some side effects. The most common side effect of Levitra (seen in one patient in ten) is pain. In addition, Levitra should not be used in people who are hypersensitive (allergic) to vardenafil or any other component of the drug. It should not be used when sexual activity is inadvisable, for example, in men with severe heart disease. Neither should patients who have ever suffered a loss of vision due to a problem with blood flow to the nerve optic, called non-arteritic anterior ischemic optic neuropathy. Levitra should not be taken together with nitrates (a group of medicines used to treat angina pectoris). If you’re looking to purchase Levitra tablets online, look no further than Pharmacy planet.
