Levitra belongs to the group of drugs for the treatment of erectile dysfunction and increases male libido. Vardenafil, the main component of Levitra, was synthesized by the pharmaceutical company Bayer in 1994. Bayer patented the name Levitra on February 8, 2000. Vardenafil neutralizes the synthesis of specific phosphodiesterase and increases the production of sex hormones that naturally stimulate sexual intercourse. penis and increase blood flow to the penis. By blocking the enzyme phosphodiesterase, the muscles of the penis relax and increase blood flow to the genital area. Erection, as a physiological process, is a relaxation of the smooth muscles of the penis. The content of vardenafil in one tablet corresponds to 10 or 20 milligrams.
How does Levitra work?
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. The maximum frequency of administration is once a day. An adequate level of sexual stimulation is needed to be effective. If you do not have enough effectiveness from the initial dose, you can increase it to 20 mg – this is the maximum daily dose.
The dosage is prescribed by the attending physician, depending on the severity of the disease. The recommended starting daily dose is 10 mg. Taking the drug should be half an hour before intimacy. The effect of taking Levitra persists for a long time. Therefore, the pill can be drunk in advance (a few hours before sexual intercourse). The effect of the drug is noticeable after natural sexual stimulation.
Treatment with Levitra is not recommended for severe forms of liver dysfunction, as well as for patients on dialysis.
Levitra is also contraindicated for women. For women, there are other drugs – this is Cialis for women and Lavgra, Viagra for women.
If the patient has a history of pathologies of the heart or blood vessels, in which sexual activity is prohibited, the drug is contraindicated. The use of the drug dilates blood vessels, which can lead to jumps in blood pressure.
In case of sudden deterioration of vision, you should immediately stop using Levitra and consult a doctor. Alcohol does not affect the effectiveness of the drug. Fatty foods slow down the absorption of the active substance into the blood. Therefore, the desired result may come much later. Levitra is a drug in most countries, so it cannot be purchased without a prescription. In France, it is on the list of toxic substances (Group I, prescription only) and does not receive any compensation from the social security program. Vardenafil can be used in pulmonary arterial hypertension when it improves hemodynamic parameters.
Unlike other erectile dysfunction medications, vardenafil is suitable for men with diabetes, high blood pressure, or high cholesterol.
Who is Levitra contraindicated for?
Some medicines may reduce the recommended dose. Therefore, if you take medications regularly and decide to try Levitra, consult your doctor or pharmacist.
The most economical way to buy Levitra 20mg tablets. Divide the tablet into four 5 mg servings and divide. If 5 mg of the drug does not suit you or is not effective enough, increase the dose to 10 mg. The maximum dose of Levitra per day is 20 mg. This dose should not be exceeded, because, firstly, the effect of the drug on it will not increase, and secondly, it is unsafe for health.
Contraindicated simultaneous use with nitrates, as well as joint use with drugs indinavir or ritonavir. Levitra is not indicated for women and children under 16 years of age. Caution should be observed in patients:

- with anatomical deformation of the penis (curvature, cavernous fibrosis, Peyronie’s disease); in diseases predisposing to priapism (sickle cell anemia, multiple myeloma, leukemia);
- with severe liver failure.
The body of older people, especially those over 65 years of age, absorbs the active substance of Levitra much more slowly, so they fully feel the positive effect of the drug when taking its lower dose.
