Before the sale, a chemical formula is worked out for each drug, laboratory and clinical tests are carried out, manufacturing technology is worked out, and the patent is obtained. This way takes a lot of time and a lot of money. Therefore, the drug manufacturing company sets a high price to cover all work related to the preparation and manufacture of a new product and to get the profit.
After the expiry of the patent, the right to manufacture this drug can be given to any pharmaceutical company. She does not spend the money on the entire previous procedure and produces it according to the finished formula. The prices are much lower. These drugs are called generics.
As a result, generics Stendra are not only not worse than original erectile dysfunction, but also have a significant advantage - a lower price that is affordable for most buyers. As in the original, it belongs to the composition Avanafil. It ensures the same effect and properties as in the original. Generic Stendra can be bought in many countries in Europe and America. Now you can do that in Russia on our website.
Effect and benefits of avanafil
The mechanism of action of Avanafil is just like other active substances with similar effects. It enlarges the vessels of the penis, strengthens the blood circulation, promotes a stronger erection. It also inhibits the production in the organism of the chemical substance PDE-5, which constricts the vessels and pushes the blood out of them after ejaculation. As a result, the erection not only becomes strong, but also permanent. All of this happens only with sexual stimulation. But most of the already recognized erectile dysfunction drugs should be taken long before the sexual act and there is always a concern that their effects will start in time. The Stendra generics relieve the man of such worries.
The effect arises as soon as 15 minutes after ingestion. The sexual enhancer works for 4-6 hours. Another important advantage - the possibility of combining the sexual enhancer with alcohol (but not more than three glasses of wine or 300 mg vodka) and with fatty food. Not all previous sexual enhancers allow this. And this advantage is really quite substantial. Because sex is often preceded by a romantic dinner with tasty dishes and alcoholic beverages.
Dosage forms and dosages of Stendra generics
There are tablets with 20 mg of the active ingredient. The optimal dose for maximum effect is 200 mg. But for those who want to try the sexual enhancer for the first time, 100 mg or 200 mg of the active ingredient is better suited. 100 mg is optimal for older men and for those who have chronic illnesses. You can buy Stendra generics in any dosage and split the tablet or drink some parts at once.
