Sildenafil Citrate Side Effects

Sildenafil Citrate Side Effects

What is Sildenafil Citrate?

Both Viagra and sildenafil are widely used to treat erectile dysfunction. In fact, they contain the same active ingredient. Viagra is a brand name for the sildenafil produced and sold by the company Pfizer. Sildenafil is also sold as a generic drug, which is medically identical to Viagra.

History of sildenafil as Viagra

Sildenafil citrate was created in 1989 by British scientists Albert Wood and Peter Dunn as a possible treatment for hypertension and angina; conditions associated with coronary heart disease. In 1991 Dr. Nicholas Terrett, now often referred to as the father of Viagra, was named in the British patent for the drug as a heart medication. And though Pfizer’s early trials of the drug in the 1990s did not prove its efficacy as a heart medication, patients who took part in the clinical trials reported increased erections after taking sildenafil. Separate studies provided more information on the biochemical process that causes erections, which helped scientists understand how sildenafil could enhance the effects of sexual stimulation and open up blood vessels in the penis. Sildenafil was then studied in men with erectile dysfunction, and in 1998 it was approved by the FDA specifically for treatment of ED.

Sildenafil (generic Viagra) becomes available

When Pfizer lost its UK patent for the drug in June 2013 it made way for generic manufacturers to produce sildenafil, or ‘generic Viagra’. It costs a fraction of the price of Viagra, and has made the treatment more accessible to a wider range of patients. You can now choose to buy Viagra, Pfizer’s branded drug, or sildenafil, the generic version.

Is one preferable to the other?

Viagra and sildenafil are medically the same. It is a requirement for the generic version to contain the same levels of the active ingredient in the body as its branded alternative, which is known as bioequivalence. Before generic drugs are licensed for sale the manufacturer must demonstrate bioequivalence to the licensing authorities (the European Medicines Agency).

If you have a private prescription for Viagra, the branded drug must be dispensed; but you may ask for sildenafil at the time that the prescription is made. They are considered equally effective, however patients must follow proper protocol for optimum results. Also note that if the condition does not respond to the initial dose of Viagra or generic sildenafil, a higher dose may be required (after several unsuccessful attempts).

In cases of recreational drug or excessive alcohol use

The level at which you drink alcohol and whether or not you use recreational drugs can impede on your ability to obtain an erection. In order to minimise the potential health risks associated with alcohol consumption, the NHS advises that adults should not drink more than 14 units over the course of one week. It is also pertinent to mention that sustained alcohol misuse can permanently damage the arteries that supply blood to the penis. Drinking alcohol or taking drugs when using Viagra can reduce its efficacy. In order to get the best possible response from the medication you should avoid drinking alcohol in excessive amounts and refrain from taking recreational drugs.
