Sildenafil Patent

Sometime ago, before the unexpected advent of Sildenafil as a significant solution to Erectile dysfunction (a condition in which a man cannot achieve or maintain an erection more commonly known as ‘ED’), the ED riddle had remained unsolved. Although, since the ‘accidental discovery’ of Sildenafil as a drug that could be used in the management of erectile dysfunction, different pieces of the erectile dysfunction puzzle have been pieced together and other drugs have been developed that perform a similar function.

In 1989, a pair of Pfizer research scientists in the UK developed a drug compound known as Sildenafil Citrate originally intended for use as a medication in the treatment of hypertension (high blood pressure) and angina, a chest pain that is caused by coronary heart disease. In the progress of carrying out clinical trials to have a better grasp of the drug compound, the researchers made a discovery that forever changed history in the medical and pharmaceutical world, they discovered the drug was more effective at enabling the subjects to achieve an erection than even the purpose for which it was intended, at the time, there was no known drug that could perform the same function and this became a business opportunity for Pfizer, hence in the early nineties, it acquired patents in the United States and United Kingdom to the little blue pill it discovered- Viagra. Although Pfizer struggled to acquire patents for its discovery of Sildenafil as a treatment for erectile dysfunction in several other countries like China, Australia and some European countries and lost, that didn’t stop it from making waves in the worldwide market for several years.

Teva Generic Viagra

In 2012, Viagra generated about $1.14 billion in U.S. sales and more than $2 billion worldwide and this market success of the drug opened the eyes of Teva Pharmaceuticals to the opportunity presented by Sildenafil. Since the year 2010, Teva Pharmaceutical Industries Ltd had plans to introduce a generic version of Viagra into the United States market but this move was blocked by Pfizer Incorporated as it sued Teva. Although Pfizer’s rights to patents on Viagra is set to expire in April 2020, Pfizer Inc reached an agreement with Teva Pharmaceuticals USA in 2013 that allows Teva to launch its generic version of the blue pill in December 2017, this is because Teva agreed to pay an undisclosed royalty sum to Pfizer for the license to produce a generic version of the blue pill.

Sildenafil is a phosphodiesterase-5 (PDE5) inhibitor meant for the treatment of erectile dysfunction (ED). Recently, when Teva Pharmaceutical Industries Ltd exclusively launched its generic Sildenafil product in the United States on December 11, 2017, its Executive Vice President, Brendan O’Grady, said that there is an estimated number of about 18 million men in the US. diagnosed with ED and the launch of Teva’s sildenafil tablets affords them a generic treatment option for ED. He also said the company’s team ensured that patients are able to access the medicine—through both traditional and more innovative channels. Teva has also made certain services available for patient support, one of such is the sildenafil savings card for those who meet set requirements to be eligible to take advantage of the program and may pay a few bucks or $0 with the most benefit of up to a hundred dollars per filling, for up to 6 sildenafil tabs prescriptions.
