Cialis and Viagra – history of invention.

Oddly enough, but Viagra appeared by chance. In the late 90s of the last century, the US company Pfizer engaged in the invention of the angina treatment drug. However, clinical trials have shown that the main drug substance sildenafil was useless. However, experimental subjects enthusiastically argued on the pleasant side effect, namely a potency improvement. Obviously, still a cash cow.

The merger of two words “Vigor” and “Niagara Falls” gave the name of the new miraculous medication. Complex tests confirmed the unusual properties of Viagra. Efficacy and safety of the pills was proven and the release of the drug was authorized by the US Drug Control Department in 1998.

The history of Cialis invention is less interesting. The medicine development had been carried out deliberately since 1993. After several years of clinical studies, the pills were allowed to be sold in 2002.

Despite the fact that different companies worked on the drug development, the mechanism of action is very similar. And it’s quite simple: medications slow down the action of enzyme phosphodiesterase 5, which affects adversely the substance responsible for the nerve impulses transmission to the penis. It increases the amount of blood flow to the corpus cavernosum penis, which leads to a natural good erection. It makes it possible to sexual contact and prolongs its duration.

Nowadays they are successfully used as a possible treatment for erectile dysfunction and a relief of symptoms of ED.

When prescribing, physicians give attention to immediate causes of erectile dysfunction and what effects patients want. Viagra and Cialis are widely used as a mild way to maintain male potency after long sexual abstinence.

If the patient doesn’t have any serious health problems he is free to choose.

It often happens that patients after a successful drug application, ask their doctors to re-assign the medication. If there isn’t any positive effect, then they ask to prescribe them another drug.

Also, doctors note that the number of patients who prefer Cialis has increased in recent years. Many people like the fact that its action doesn’t occur immediately, and they may not be afraid of instant erections, which is not always convenient.

If talking about efficiency and price of Cialis versus Viagra, most men making a choice do not rely on these characteristics. Cialis and Viagra is effective in the majority of cases (about 70%). Their price range is also almost the same; Cialis can be a bit cheaper.
