What is Viagra?

Let’s start with the basics. Viagra (sildenafil citrate) is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. It works by increasing blood flow to particular areas of the body.

The Beginning

Back in 1989, Pfizer began clinical trials for a drug called UK-92480 which was intended as a treatment for angina pectoris (chest pain caused by insufficient blood flow to the heart muscle). Surprisingly enough, during these trials, researchers noticed something peculiar: Many male patients experienced improved erections after taking UK-92480!

Being scientists and all, Pfizer didn’t just brush this off; instead they decided to pivot from developing an angina medication and focus solely on treating ED.

Creation

Nonetheless perseverance paid off when FDA approved blue diamond shaped pill hit market shelves on March 27th 1998.

It rapidly garnered attention and praise from couples worldwide struggling with bedroom issues. Despite waning effects within four hours post consumption along with side effects; including dizziness, headaches or pink eye ‘poppers’ remained popular due its serious reputation blurring street usage line between recreational & pharmacological use. In 2003, the FDA approved it to treat pulmonary hypertension too.

Patent Laws

Now you might be thinking: If everyone loved it so much then why did Viagra come off patent? Great question!

Pfizer’s patent for Viagra was granted in 1996 and would have expired in 2012. Generally speaking, when a company creates a new product they are allowed exclusive rights to produce and sell that product for a certain amount of time – typically twenty years from the date of application (1).
