Levitra helps to treat erection dysfunction

Pharmaceutical companies became interested in the development of the drugs aimed at the treatment of erectile dysfunction after the production of Viagra in 90’s years. They reached some success, using as a basis the same enzyme, but slightly improved it. As a result they developed such a drug as Vardenafil, the trade name – Levitra. This is a natural medicine that allows achieving considerable success in the treatment of sexual dysfunction. Vardenafil helps to strengthen potency, prolong the time of sexual intimacy, restores normal operation of the genitourinary system. A drug does not cause addiction, they are fully harmless for any ages, if you follow the instructions and do not use them at some severe diseases associated with the cardiovascular system.

Drug for male strength

Due to Levitra you may solve a number of physiological problems connected with a man's health:

  • to cure the symptoms of erectile dysfunction, including in older patients
  • improve endurance during sexual intercourse
  • prolong the time of intimacy
  • cure low sexual activity
  • get a more vivid feeling
  • recover before the next erection about half an hour

Main pharmacokinetic functions

After taking the pill orally Vardenafil is absorbed from the gastrointestinal tract. If taken on an empty stomach, it takes 15 minutes for the action of the concentration of the drug. However, such optimistic indicators should not be the basis, the results of the studies show that the peak concentration occurs between 30 to 120 minutes. On the other hand, the clinical effect comes earlier than a sufficient amount of the drug reaches the blood plasma.

The duration of action of Vardenafil varies individually from 4 to 8 hours. In any case, it is much longer than the effect of Viagra. More than 50% of patients reported action within 25 minutes after taking. An erection was quite sufficient for sexual intercourse and orgasm in half of the patients with mild to moderate erectile dysfunction. All patients may feel Levitra effect in one hour after taking. According to statistics, successful sexual acts with this drug account for more than 90% of the total.

Note, Vardenafil is absorbed at a slower rate with fatty meal, and the effect of the drug will come no earlier than an hour. One of the benefits of medication is the lack of its influence on the activity and quality of sperm. Measurements of seminal fluid 1,5 hours after taking the medicine have identified no more than 0, 00012% of dose Levitra.

The drug is excreted by excrement (up to 95%) and urine (up to 6%). It is worth noting the studies of different age groups showed that Levitra has the same efficacy as for men older than 65 years and for patients of 40 to 65. Vardenafil can be administrated in patients with mild and moderate pathology of the kidneys and the liver, because it almost has no effect on the body.

How many sexual acts can be made after taking Levitra?

Young people who lead an active sexual life (under 45 years) are concerned by this question. During the action of vardenafil the number of erections varies from 4 to 10, each of which lasts from 15 to 60 minutes.
