The most famous drug for the treatment of erectile dysfunction in men is called Viagra Pfizer. Its manufacturer and the owner of expired patent is the company “Pfizer”. The legendary original Viagra was based on Sildenafil, and its action lasted up to 4 hours after the intake. The initial dose for most men is 50 mg of Viagra. It must be taken 30-60 minutes before the beginning of sexual act.
It is not recommended to mix Viagra with fat food and alcohol. Otherwise, the drug absorption will be worse, its action will be delayed, and its effect won’t be so impressive. You can buy Viagra online and be sure that the use of Viagra will allow you to achieve stable erection (provided that you have sexual stimulation).
When considering the difference between the generic Viagra and original Viagra, we should note that a distinct feature of Viagra Pfizer is its popularity, publicity and therefore price. Viagra is a first drug for the treatment of impotence that appeared on the market before the other similar drugs.
It is easy to distinguish the original drug. Cheap Viagra comes in the diamond-shaped blue pills. On the one side, they contain 3 capital letters — VGR and the quantity of the main substance in mg. On the other side, it has the name of manufacturer– Pfizer.
When you buy Viagra online, you should pay attention to the right lower corner of the box. It must contain the hologram. Depending on view angle, here you can read “VIAGRA”or “Pfizer”.
Creation of viagra sildenafil citrate
Viagra can increase the blood flow to the penis, providing natural erection in the presence of sexual arousal. After the sexual act, penis returns to its normal state. The drug for the treatment of erectile dysfunction was developed by accident. The pharmaceutical company “Pfizer”was testing Sildenafil citrate. This drug was intended for the treatment of cardiovascular diseases.
They expected that Sildenafil would reduce the blood pressure due to the increase of blood flow to the cardiac muscle. However, there was no such effect. Instead, the medicine improved erection. The new drug was called after the large waterfall of the North America “Niagara” and the word “vigor”, which means power and energy. Viagra sildenafil citrate passed the numerous tests and showed high effectiveness and safety.
Patent infringement
In 1998, Sildenafil citrate was patented by the company “Pfizer” (the patent was valid until 2012). In 2002, “Pfizer” got the new patent for the use of Sildenafil as an active substance of Viagra, valid until 2019. The company has author’s rights for Sildenafil citrate and doesn’t allow to use this substance in the drugs for potency problems with different names based on Sildenafil.
Viagra Generics
Viagra Generics are different medications for increasing the potency. They all have the same main active component as cheap Viagra- Sildenafil citrate. Apart from Sildenafil, all generics contain the other components, improving the drug effect.
Actually, Viagra is the drug, allowing you to get rid of some psychological complexes and fears of sexual failures. The one-time use of the drug (or several uses) after you order viagra without prescription, provides the successful sexual activity, but you shouldn’t abuse the drug. The real reason of sexual dysfunction must be clarified by the qualified specialist (urologist or sexologist).
It is undesirable to mix generic Viagra with alcohol, as it is able to decrease the drug effect. The erection can be weak or not appear at all. However, clinical pharmacologists helped the men by creating the drug formulation that dissolves under the tongue. Therefore, Viagra sildenafil citrate is not mixed in the stomach with ethyl alcohol, which allows combining it with the alcoholic drinks and fat food, which also prevents the proper absorption of the drug.
