Levitra is the brand name for vardenafil, an oral medication used to treat men who have sexual impotence, also known as erectile dysfunction or ED.
Vardenafil (INN) is a PDE5 inhibitor used for treating erectile dysfunction.Vardenafil's indications and contra-indications are the same as with other PDE5 inhibitors.The difference between the vardenafil molecule citrate is a nitrogen atom's position and the change of sildenafil's piperazine ring methyl group to an ethyl group.Tadalafil is structurally different from both and vardenafil.Vardenafil's relatively short effective time is comparable to but somewhat longer than sildenafil's.
LEVITRA (vardenafil hydrochloride) is administered orally for the treatment of erectile dysfunction. This monohydrochloride salt of vardenafil is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5).
It is a highly selective PDE-5 inhibitor, playing a role in the treatment of the penile erection mainly through specific inhibition of PDE-5 activity. Compared with similar products of the drug, it has the characteristics of fast onset of action, efficacy reliable, high quality and erection of good security.
Levitra increases venous congestion in that area and helps a man get and keep an erection during sexual intercourse. By itself, Levitra does not cause an erection - there must also be physical stimulation of the penis to achieve an erection. Levitra is only for use in men. Women should never take it, especially if they are pregnant or breastfeeding.
Vardenafil has been licensed to treat erectile dysfunction. Erectile dysfunction (ED), also known as impotence, can be a total inability to achieve an erection, an inconsistent ability to do so, or a tendency to sustain only brief erections. Essentially, erectile dysfunction is the repeated inability to get or keep an erection firm enough for sexual intercourse.
