Levitra (Vardenafil) is an effective medication used to treat erectile dysfunction. The drug is only useful with sexual desire and stimulation. Vardenafil releases nitric oxide from the nerves endings of the cavernous bodies of the penis and activates enzyme guanylate cyclase, which in its turn produces cyclic guanosine monophosphate, which results in an intensified blood flow to the penis.
Dosage and direction
The recommended initial dose of Levitra is 10 mg per day. Take 1 tablet 1 hour prior to sexual intercourse. If you have no side effects, the dosage can be increased up to 20 mg per day. If you have adverse effects, the dose should be reduced to 5 mg per day. Do not take more than 1 tablet per day.
