Is There A Generic Form Of 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.

What Does the Term 'Generic' Mean Anyway?

Simply put, a generic medicine is a drug created to work like an existing, brand-name treatment.According to the FDA, generic medicines work the same way and provide identical benefits as brand-name drugs. In fact, generic drugs must meet rigorous standards to receive FDA approval.

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.

How Generic Pills May Be Different Than Brand-Name Pills

You should know there may be slight cosmetic differences between generic and brand-name drugs. The color, shape, packaging, and labeling of the medicine could vary. Also, generic medicines may have different inactive ingredients, so they might have a different flavoring.

Herati says the generic version of Viagra should be very similar to the brand-name medicine. “[We] will have to wait for pharmacologic studies to see how long it takes the medication to show effect, what its duration will be, and what restrictions will be placed with it,” he says.

Efficacy, Side Effects and Contraindications

The results of the products are clinically the same.As previously mentioned, Viagra and Sildenafil have the same active ingredient, and perform the same function in the body. This means that they have the same rate of efficacy, carry the same risks of side effects, and are subject to the same contraindicatory restrictions.Despite the fact that Sildenafil is available, there is a reason that Viagra continues to sell so well; because it is the most established and recognisable prescription medication available for impotence, and will perhaps remain to be for some time.

Appearance and Form

In addition to retaining the Viagra name, Pfizer also retained the trademark on the appearance of the drug; the blue diamond shape.

Subsequently, manufacturers of Sildenafil are unable to produce the drug with a similar appearance.

Usually, Sildenafil will be issued simply as a regular-shaped blue or white tablet; however in 2012, Nipatra, a chewable version of sildenafil was released by Mercury Pharma.

Whereas Viagra tablets have ‘VGR’ and the dosage amount inscribed on them, Sildenafil will normally have ‘SL’, followed by the dosage.

Blue or white pills?

Branded Viagra comes in small diamond-shaped blue pills – Pfizer has also patented this pill design and appearance. Sildenafil is sold as white or blue tablets, with different characteristics depending on the brand. Some have chalky finishes while others are smooth, and some are scored for easy division, while others are not. Both Viagra and the different brands of sildenafil can be purchased in 25mg, 50mg, and 100mg preparations, and there is no significant difference between them in terms of active ingredients.

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).
