Who invented the Viagra?

Viagra, a drug for erectile dysfunction treatment, was developed about 20 years ago, but many men still wonder “Who invented Viagra?”.

The permanent interest in this issue stems is explained by the fact that almost 20 years have passed since Viagra was launched, but this drug is still in the top 5 of the most prescribed medications worldwide.

The main active ingredient in Viagra pills – Sildenafil, was invented by Pfizer pharmaceutical company employees. Initially, the research laboratory employees investigated Sildenafil as a pharmaceutical agent for treatment of cardiovascular diseases such as angina or hypertension.

The first trial of a prototype of Viagra pills was conducted in 1991. The results of this study showed that Viagra provided just a minimal effect on the cardiovascular system. However, one of its side reactions was positive effect on erection.

In 1994, Pfizer’s leading specialists began to study the effect of Viagra on the male erectile function. During laboratory tests, they revealed that the mechanism of drug action was in PDE5 enzyme inhibition in the penile cavernous tissues.

Then, for three years, Pfizer conducted over 20 clinical trials of Viagra, with 4500 male participators of reproductive age. The results of these studies demonstrated Viagra to significantly improve male sexual function and to treat successfully erectile dysfunction of different types and varying severity.

In 1996, Pfizer patented Viagra as the first oral drug for erectile dysfunction treatment, and in a just few years, this drug appeared on the drugstore shelves.

Many Pfizer employees were involved into Viagra development. However, the patent application could not mention all their names. Therefore, as the authors who invented Viagra, the document listed the names of several company employees, including:

  • Peter Dunn – Researcher;
  • Albert Wood – Researcher;
  • Peter Ellis – Executive Director;
  • Nicholas Terrett – Head of the Chemical department.

In 1998, the FDA recognized Viagra as the best oral drug for erectile dysfunction treatment, with proven efficacy and a high safety profile.

Right once Viagra was launched, “little blue pills” were recognized by a large number of men and specialists involved in treatment of male sexual dysfunction.

Despite that hundreds of different medications for ED treatment are currently available, of Viagra, invented at the end of the last century, is still considered to be the most popular drug which changed forever an idea about efficacy of ED treatment.

How long does it take for Viagra to work?

If you want to learn how long does it take for Viagra start acting, please, read this review. More information about Viagra pills allow to understand better the mechanism of drug action and to get the maximum benefit in erectile dysfunction treatment.

The start time for Viagra or any drug depends on the following factors:

  • Pharmacokinetic properties of the active substance.
  • Individual’s features.

Viagra starts acting right upon the active ingredient (Sildenafil Citrate) gets into the blood. However, the optimal effect of Viagra is achieved at maximum Sildenafil (Generic Viagra) plasma concentration (Cmax).

Clinical trials have revealed that Cmax Sildenafil is observed in plasma for 30 minutes to 2 hours after one Viagra pill of 25mg, 50mg or 100mg.

If you’ve never treated your erectile dysfunction before, then one Viagra pill is recommended to take about 60 minutes before expected sexual activity. Also you can take Viagra within 4 hours prior to sexual intercourse.

Viagra pills start working only after sexual stimulation. If you take a pill of Viagra 25mg, 50mg or 100mg, without sexual arousal erection is not achieved.

Pharmacokinetic properties of Viagra depend on the dosage used. The higher recommended Viagra dose you take, the higher the Cmax value.

However, the maximum daily dose of Viagra 100mg is not mandatory for a good drug action. Most men with some difficulty in erection achieving or maintaining are recommended to use Viagra 50mg tablets.

Food affects Viagra pharmacokinetic properties. A Viagra pill taken on an empty stomach provides erection faster than used after breakfast, lunch, dinner or snack.

Too much saturated fats in your diet inhibit Viagra action. For example, if you take a Viagra pill after a few slices of pizza or hot dogs, the time to maximum Sildenafil blood concentration is increased by about 30%.

A men’s age may affect Viagra action. Older people have slower metabolism. Therefore, men above 65 years old experience longer Viagra effects.

If you want Viagra to act longer, effectively and safely, do not take it with alcohol. Ethanol decreases the blood flow to the penis and increases risk of Viagra side effects.
