Vidalista helps to achieve good erection during sexual intercourse and works improving blood flow in the penis relaxing arterial smooth muscles. It works only when sexual stimulation is present. The main component of Vidalista is Tadalafil.
Tadalafil is an effective, reversible, selective inhibitor of phosphodiesterase type 5 (PDE 5) specific to cyclic guanosine monophosphate (cGMP). When sexual stimulation causes local release of nitric oxide, inhibition of PDE 5 by Tadalafil leads to increase of cGMP levels in the cavernous body of penis. It results in relaxation of arterial smooth muscles and blood flow to the tissues of the penis that causes erections. Tadalafil has no effect when sexual stimulation is absent.
The recommended dose of Vidalista 20 is 20 mg it should be taken at least 16 minutes before the sexual activity. The effect persists during 36 hours. Take Vidalista once daily and do not exceed the recommended dose.
It is preferable not to use Vidalista with grapefruit juice, alcoholic beverages, tobacco. If you smoke tobacco and take Vidalista concomitantly this may lead to a condition called NAION (sudden optic nerve-related vision loss). Inform your doctor before to take Vidalista if you have abnormal penis, including curved penis and birth defects of the penis, had coronary artery disease, arrhythmia, angina, heart attack or heart failure, hypo- or hypertension, bleeding, stomach ulcers, diabetes, hyperlipidemia (excess of lipids in the blood), sickle-cell anemia, liver or kidney failure in history.
Vidalista is contraindicated in patients who are using any form of organic nitrate, either regularly and/ or intermittently as it is able to potentiate hypotensive effect of nitrates.
Most usual side effects of Vidalista are facial flushing (reddening), headaches, stomach upset, diarrhea, flu-like symptoms and nausea. In more rare cases low blood pressure, blurred vision and changes in color vision, and abnormal ejaculation may occur. Prolonged erections or priapism (painful erections lasting more than 6 hours) are also possible. If your erection is longer than 4 hours, seek for immediate medical help as it may permanently damage your penis. Aggravation of heart problems in patients with pre-existing heart disease using Vidalista was reported.
