About Viagra

Viagra, an oral therapy for erectile dysfunction, is the citrate salt of Sildenafil, a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5). When the sexual stimulation causes local release of Nitric Oxide, inhibition of PDE5 by Sildenafil causes increased level of cGMP in the corpus cavernosum resulting in smooth muscle relaxation and inflow of blood to the corpus cavernosum.

Viagra is formulated as blue, film-coated rounded-diamond-shaped tablets and is one of the most commonly sold drug for treating male erectile dysfunction or impotence. It is also used for treating pulmonary arterial hypertension (PAH). The drug was developed by the pharmaceutical company Pfizer. Viagra is also informally known as “Vitamin V” or “the Blue Pill”.

Ingredients of Viagra

Viagra is contra-indicated in patients on nitrate therapy and with a known hypersensitivity to any ingredient of the tablet.

In addition to the active ingredient Sildenafil Citrate, each tablet contains the following inactive ingredients: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose, triacetin, and FD & C Blue #2 Aluminum Lake.

Sildenafil Citrate May be Linked to Vision Loss

David asked:

Viagra, Cialis, and Levitra have varying side effects, though they are rare and generally mild. However, a recent study found that sildenafil citrate (the active ingredient in the drugs Viagra, Cialis, and Levitra) has been linked to loss of eyesight in some users. Generally the loss of eyesight occurs in one eye, and is a condition called non-arteritic anterior ischemic optic neuropathy (NAION). Although numerous men suffering from NAION have taken sildenafil citrate for sexual dysfunction or erectile dysfunction, it has not been confirmed that there is a cause-and-effect relationship between taking the drug and the condition. People with a high risk of NAION include:

• Men with heart disease.

• Men over the age of 50.

• Those who have diabetes.

• Men who have high blood pressure.

• Those who have high cholesterol.

• Smokers.

• Those with other eye problems.

If you are taking Viagra, sildenafil citrate, Cialis, or Levitra and have experienced a loss of eyesight, stop taking the drug immediately and consult your physician. Only a licensed physician can be sure if the drug is qualified to assess your loss of sight. The FDA is not currently scheduled to print Viagra warning labels that include a statement about the possible correlation between sildenafil citrate and NAION.

This is another great reason why when buying Viagra or sildenafil citrate, your original prescription should be written by your physician. Only a physician can adequately assess an individual’s risk level for experiencing any undesired side effects from Viagra or similar drugs. Only after the original prescription should patients buy Viagra online. Although buying Viagra online can save a great deal of money and is more discreet, it sometimes means those beset by erectile dysfunction may further suffer from lack of a physician’s oversight.
