Levitra does not stimulate libido, but only enhances natural sexual arousal. The action of the drug begins 30-50 minutes after ingestion. The exposure time is 5-10 hours. In patients with liver or kidney disease, the elimination of drug components may take longer.
According to statistics, 52% of men aged 40 to 70 suffer from erectile dysfunction of varying degrees. The pharmaceutical industry offers a wide range of drugs to restore their effectiveness. The first of the so-called “PDE-5 inhibitors” on the world market is Viagra, a drug containing the active ingredient sildenafil citrate. The second, first in the US, and then around the world, was Levitra, and the third was Cialis.
The medicine is taken orally, regardless of the meal. The recommended starting dose is 10 mg 25-60 minutes before sexual intercourse. Levitra can also be taken 4-5 hours before sex.
