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.
Due to Levitra you may solve a number of physiological problems connected with a man's health:
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.
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.
About 10% of patients had complaints on headache, rush of blood to the face. Less than 10% felt discomfort in the epigastrium, rhinitis. From 0.1 to 1% of subjects complained of dizziness, attack of sleepiness, jumps of arterial pressure, increase of some indices of liver function, reduction of the brightness and clarity of vision, swelling of face, pain in back and loins, shortness of breath. Less than 0.1 % of men experienced such problems as: angina, swelling of the throat, muscle hypertonicity, prolonged erection, and visual impairment. You should immediately call your physician in case of occurrence of such symptoms. Some vision impairments were associated with diseases of vessels and had nothing to Levitra.
Despite the fact that the drug has no negative effect on the heart and blood vessels, there is a number of contraindications for its taking.
The pill can be taken at any time of the day with or without meals. According to the instructions it is recommended to start with a dose of 10 mg, but a doctor can prescribe an initial dosage of no more than 5 mg in the case of some complications (renal failure, age over 65 years).
Levitra is taken in 30 to 60 minutes before the expected sexual contact, but the term may be increased. However, it is necessary to limit taking once per day. The manufacturer recommends taking no more than 20 mg daily. After consulting a physician the same dosage is acceptable to older people and patients who have a mild form of liver failure and slightly expressed kidney dysfunction.
