Stendra (Avana): General information

Avanafil.svgStendra refers to PDE5 inhibitors that are tailored to the treatment of erectile dysfunction. It was approved by FDA in 2012. In 2013 the drug was announced to enter European, Australian and New Zealand markets.

Stendra’s main active ingredient is Avanafil, the new-generation PDE5 inhibitor that can meet the competition of such market leaders as Sildenafil, Tadalafil or Vardenafil. Avanafil’s competitive advantages include fast adsorption in the human body (within 30-45 minutes) and response: more than two thirds of the customers prove their ability to start sexual intercourse in 15 minutes after the intake of Avanafil. The medical action lasts for up to 6 hours usually.

Stendra is produced in the form of pills containing 50 or 100 mg of Avanafil.

What does Stendra do?

What does Stendra doThe major therapeutic indication of Stendra (Avanafil) is erectile dysfunction treatment.

Erectile dysfunction is connected with an inability to reach and maintain erection for the period needed to start and finish coitus. In most cases ED problems are caused by the age-related factors. However, the reasons of ED can also involve such factors as bad habits, professional stresses, hard working conditions, suffered health disorders, bad eating habits and so on. As a result, men, often even younger than 40 years old, are not able to conduct healthy sexual life.

Stendra does not treat the reason of erectile dysfunction, but it effectively improves the symptoms. The major distinctive feature of Avanafil is that it influences only natural mechanisms of erection. In order to get rid of the ED reason additional therapy or changes of lifestyle and habits are required.

Avanafil relaxes plain muscles and widens the blood vessels. More intense blood flow provides more stable and stronger erection. Avanafil is effective only if there is a sexual excitement as the excitement is responsible for the emission of cGMP (cyclic guanosine monophosphate) that works in penis. Avanafil starts acting after the emission takes place and prevents cGMP from fast degradation. As a result, a man is able to maintain erection and to conduct full sexual intercourse.

Stendra is available only with the prescription and is not tailored to children under 18 years old and women.

What is the difference between Stendra and other ED drugs such as Viagra?

Stendra is a new medication that appeared at the market several years ago. Like any other ED treatment drugs it refers to the group of PDE5 inhibitors that cure the ED symptoms by influencing natural mechanisms of erection. Manufacturers of Stendra claim that the medication has rare side effects which usually disappear in the course of treatment. Like other PDE5 inhibitors Stendra is available with prescription and should be taken once a day. Stendra has the same contraindications as most of branded ED treatment medications and their generics have.

Do I have side effects if I overdose?

If you decide to take larger dosage without consulting your health care expert you may certainly suffer from side effects. The dosage your doctor recommends is prescribed according to your current health state. If you have any health problems increased dosage of Avanafil will intensify side effects related to your troubled area. That is why it is important to follow the doctor’s recommendations and not to increase the dosage without visiting the doctor.

What should I do if I forget to take the daily dosage?

Stendra is taken on demand and does not require regular intake. If you want to have sex you just need to take the prescribed dosage half an hour before the sexual intercourse. Do not split the dosage or take two dosages within 24 hours. In the first case you will not have the desired effect, in the second case you may suffer from the unwanted deterioration of the health state.
