LEVITRA 60mg is an oral medicine for the treatment of Erectile Dysfunction (ED). ED is a familiar cause of impotency among the males of the age group of 30 to 60 years. It contains verdenafil which is a Phosphodiesterase 5 (PDE 5) inhibitor as the active constituent. It has a long lasting effect of 10 hours. LEVITRA tablets are available in various strengths. It should be administered 25 minutes before sexual activity. It is not having any aphrodisiac (sex stimulant) activity and also it does not provide any protection against sexually transmitted disease. It has to be taken only when required.
Erectile Dysfunction (ED) is the inability to retain rigidity of penis high enough for successful sexual intercourse.
MECHANISM OF ACTION
Verdenafil treats erectile dysfunction by acting as inhibitor of an enzyme named “Phosphodiesterase 5” (PDE5). PDE 5 degrades cGMP present in the erectile tissue of the penis, vascular endothelium (walls of blood vessels) and retina (eyes). When the man is sexually stimulated, nitric oxide is released by the nerve ending which in turn trigger production of cGMP resulting in relaxation of vascular smooth muscles and improved blood flow to various tissues of the body. LEVITRA augments the concentration of cGMP in tissues by inhibiting PDE5. Increased cGMP cause vasodilation of the blood vessels of the penis resulting in erection.
LEVITRA is used to treat impotency in males by treating the erectile dysfunction. It is a prescription drug. However it does not permanently treat erection problems.
