Vardenafil is intended for treating erectile dysfunction. This active substance is contained in Levitra. A man’s erection is a hemodynamic process, this means that relaxation of smooth muscles in cavernous bodies occurs. Thus blood flow to penis increases. Vardenafil, in its turn, strengthens the action of nitrogen oxide in cavernous bodies during sexual stimulation.
Vardenafil is taken orally. The substance’s absorption happens quite fast. In 15-20 minutes the medication starts acting. The effect lasts up to 5 hours. Vardenafil is used by those who cannot retain a lasting erection for successful completion of a sexual intercourse. It can happen for various reasons: age, high cholesterol, diabetes. It should be highlighted that the substance does not influence a man’s libido.
The medications’ main contraindications are hypersensitivity to any of its components and taking it jointly with nitrates. The men with penis deformation, leukemia or significant liver disorders should be careful while taking the medication. If a patient has minor liver disorders, then he should take no more than 5mg of vardenafil a day. The standard dosing is 10mg a day. It is not recommended to take more than 25mg of this medication a day. However, even if a major erectile dysfunction is observed, it’s recommended to start from taking 10 mg of vardenafil a day.
Speaking about alcohol and fatty foods, they do not influence the medication’s effect at all. Vardenafil starts acting only after sexual stimulation. The most widespread side effects of the medication are headache, backache, sleepiness, nasal bleeding. Still all of them occur quite rarely and are moderate. In case of overdosing the side effects do not aggravate in direct ratio but remain quite mild. Taking this medication with nitrates is counter-indicative.
