Levitra is a phosphodiesterase type 5 inhibitor, which is widely used for erectile dysfunction treatment (inability of achieving and keeping up an erection, required for sexual intercourse).
The drug is considered to be alcohol-compatible.
This medicine not only is a decent rival to Viagra and Cialis, but also has excelled its competitors in some aspects. It is possible to find the drug without prescription.
Even though the brand is quite expensive and can hit a man in his wallet, there is an economical alternative of high quality: generic drugs. Generic Levitra, or vardenafil, has absolute bioequivalence, comparing to the original medication. It is also used to treat male erectile disorder and impotence. It may differ in taste, color of tablets, or their shape, but it is the same pharmaceutical on a large scale, which has successfully undergone numerous clinical trials.
This medicine does not cause an erection by itself. Just as usual, the key factor still is sexual arousal, without stirring up the libido. The drug does not bring about hormonal imbalance or change nervous or cardiovascular system regular functioning. It is harmless for those who are planning for pregnancy. There is no way in which this pharmaceutical could have an impact on future baby.
How vardenafil works
Healthy men achieve an erection as the result of blood supply to penis tissue, induced by sexual arousal. Abnormalities in vessels functioning in and around the small pelvis are capable of blocking the blood supply, which is the main reason for male erectile disorder. Vardenafil functions as a relaxant for penis nonstriated muscles, which leads to the relaxation of arteries and its dilating capacity increase.
As a result, a man has healthy and completely natural erection. This generic drug restores erectile function for approximately 12 hours, and the maximal effect occurs in the first hour after taking the medicine.
Women and children should not use this medication. The use of this drug is also contraindicated for those who have susceptibility towards any of its components.
Levitra should be taken carefully and under the medical control if a patient suffers:
- Penis deformation
- End stage renal diseases
- Severely compromised liver function
- Inherently prolonged QT interval
- Priapism predisposition (diseases like leukemia, multiple myeloma, sickle-cell disease)
- Pigmented retinitis and other degenerative hereditary retina diseases
- Low blood pressure
- Instable angina pectoris
- Ulcer exacerbation or inclination for bleeding
It may be risky to take the medicine during the renewal period after the stroke or myocardial infarction.
Side effects of Levitra
As a rule, this medication causes no apparent adverse effects. These are some typical body responses to the drug:
- Headaches and periodical giddiness
- Low back pain
- Arterial tension increase
These effects mostly happen when organism adapts to the drug; they become weaker with subsequent usage, and then completely disappear with time.
There were cases when Levitra was taken in dose of 80 mg once per day and 40 mg once per day during 4 weeks without serious adverse reactions. However, when taking 40 mg twice per day, there could be evident low back pain without signs of toxic influence upon muscle and nervous system.
Symptomatic and supporting therapy is a good treatment in this case. The efficiency of hemodialysis is unlikely since the kidneys excrete only insignificant quantity of the medication.
