Sex is an indispensable aspect of any love relationship. The absence of satisfactory sex has been the cause of many a split relationships and an alarming number of suicide attempts and even deaths. The medical condition for failure to satisfy the female spouse is known as erectile dysfunction (ED). ED or impotence is a serious men's health concern and if left untreated, can have devastating effects on the lives of the sufferers.

Realizing the seriousness of the matter, many pharmaceutical companies are devoting millions and billions of dollars towards the R&D of specific drugs. The results of their efforts bore fruits when the US FDA approved Viagra as the first prescription oral drug for the treatment of ED in 1998. The public response towards Viagra was phenomenal. The men just lapped it up like a magic pill. The marketing people went overboard in their efforts to get men buy Viagra. The ED treatment just got better in 2003 with two more drugs - Levitra and Cialis - getting FDA approval.

Levitra (vardenafil HCl) follows Viagra in revolutionizing the ED treatment. Manufactured by Bayer Corporation of Germany and marketed globally by Glaxo Smith Kline, Levitra was approved by the US FDA in 2003 as prescription drug for the treatment of erectile dysfunction. It became second such drug only after Viagra.

The working of Levitra is similar to that of Viagra. It allows the muscles in penis to relax which allows the blood to flow in and induce a firm erection. But Levitra is equally effective in smaller dose where Viagra requires larger dose to achieve same level of effect. It shows the positive effects within 15 minutes of taking the pill and lasts for about 6 hours. Spells leisure and pleasure in a large measure!

The biochemical differences between the two drugs are that Levitra contains a more efficient enzyme inhibitor, so the person can take only a very small amount of the drug which is necessary.

Levitra is said be functional within 25 minutes of intake and may work up to 24 hours. Levitra increases the flow of blood to the penis and helps in achieving erection for sexual activity. Recent clinical studies reveal, Levitra to have treated erectile dysfunction in patients having related health factors like diabetes and prostrate surgery. So at a time when diabetes remains a threatening factor causing E.D., Levitra might be a boon to many.

No doubt, Levitra gives a tremendous boost to the sexual health of the partners. But there are a few cautions that must be observed before you buy Levitra . Being a prescription pill it must be bought only after proper diagnosis and prescription by a qualified GP. The knowledge of side effects of the drug must be obtained from your GP and the pharmacist.
