Medical drug with the active ingredient Vardenafil is an advanced analogue of the widely known Sildenafil and is designed to treat erectile dysfunction in adult men of any age.
Let’s speak simply. What is erectile dysfunction? It is the inability to achieve a stable erection and/or maintain it for sexual intercourse during the sexual excretion. Very often men often confuse this problem with a number of other diseases or individual peculiarities. You should consult a doctor and undergo examination before taking Sildenafil in order not to harm your body by uncontrolled drugs taking for erection dysfunction treatment.
It will be useful to know the mechanism of action of Levitra if Levitra or other PDE-5 inhibitors are prescribed. PDE-5 inhibitor is a means that blocks emitting isoenzyme phosphodiesterase. Actually an enzyme prevents the relaxation of smooth muscles of the penis in order to have blood flow and erection. Slowing the action of the enzyme, Levitra restores natural and normal process that occurs at sexual arousal.
Thus, Vardenafil helps to fortify healthy male reaction.
Vardenafil, as other analogues, absorbed rapidly. In comparison with Viagra its advantage is that the effect of tablets begins in 15-20 minutes after taking. Peak concentration occurs within an hour. Ordinary food does not affect absorption of the drug; fatty food should be excluded, because it reduces the pharmacokinetics.
The drug is intended to treat dysfunction and is not itself the stimulant, an aphrodisiac or something similar. Its main function is to maintain normal blood flow in the pelvic organs. Therefore, to provoke spontaneous and furthermore very long erection by itself it can't.
This is one of the rare side effects and it was registered in less than 0.1% cases. Leukemia, multiple myeloma, sickle cell anemia can be the risk factors in this case. It is undesirable to use Levitra in the case of these diseases.
In all other cases a man needs to be aroused in order the drug to have effect.
Pills are available in dosages of 5, 10, 20 mg. They can be taken orally regardless of the time and without regard to food intake, for half an hour before intimacy. A healthy man between 22 and 45 years of age needs 10 mg (initially) and if necessary, after the consultation with the physician, the dose may be increased to 20 mg. As usual, the maximum daily dose is prescribed to patients suffering from prostatectomy, who suffer from severe dysfunction of pelvic organs blood supply.
The recommended dose for the elderly 65 and older is 5 mg per day. If it is necessary, the doctor may increase the dose to 10 mg in the absence of side effects. The same applies to those who have a history with mild and moderate forms of hepatic or renal failure.
In some cases, it is contraindicated to use the tablets:
Levitra is strictly contraindicated to children under 18 and women.
The cases of 2 times and 4 times overdose were registered; the overdosage invoked the negative side effect in the form of back pain. Overall, Vardenafil can cause such feelings:
10% of the subjects of experiment observed mild headache, slight visual impairment, and namely, turbidity, color mix, dizziness, drowsiness. Less than 1% noted cases of dyspepsia, rhinitis, swelling and redness of the face, pain in the back muscles or feet.
There is a risk of adverse reactions or complications during the use of Levitra in case of any chronic cardiovascular diseases, so you need to consult a physician. You can drive a car after vardenafil use, but because of possible visual disturbances you should wait about half an hour.
Vardenafil should not be combined with other drugs for the treatment of erectile dysfunction because their combined effect has not been studied and undesirable side effects may be revealed.
In the case of co-administration Levitra and erythromycin, ketoconazole, the dose of Levitra should be reduced to 5 mg. Levitra should not be combined with alpha- adrenoceptor blocking drugs to avoid the risk of arterial hypotension.
