Sildenafil 20 mg: What Is This Drug?

Sildenafil is a life-saving drug. This medicine is also known as a vasodilator, a drug that works by dilating the blood vessels in the body enabling a better circulation of the blood. But how does it do that?

Inside our bodies is an enzyme called Phosphodiesterase type 5 or also known as PDE 5. This enzyme is responsible for the normal blood pressure in the body by making sure that the muscles surrounding the blood vessels have enough pressure so the blood can circulate back to the heart from the other parts of the body. While Sildenafil works to inhibit this enzyme, it is only for a temporary period of time. This action of Sildenafil relaxes the muscles and expands the blood vessels, allowing them to handle increased amounts of blood.

These functions that Sildenafil does in the body works perfectly for Pulmonary Arterial Hypertension and Erectile Dysfunction. Since Pulmonary Hypertension is a condition caused by the pulmonary arteries that have thickened, Sildenafil dilates these affected arteries so that the blood will flow easily from the heart to the lungs. If left unchecked, Pulmonary Hypertension could lead to heart failure and other fatal health conditions. Sildenafil works terrific as well for Erectile Dysfunction. Because of the dilated blood vessels in the body, the amount of blood flowing to the penis will also increase and become constant for the duration of Sildenafil’s efficacy. This will now aid the penis to attain sustained erections which are stronger than what the body can normally achieve.

Pfizer is the manufacturer of these drugs. Its Sildenafil brand for Erectile Dysfunction is Viagra and its brand Revatio is for Pulmonary Hypertension. Sildenafil intake is not the same for ED and Pulmonary Hypertension. Since ED uses Viagra which has larger dosages, it is only taken once every 24 hours and only when needed. Taking Viagra more than once a day comes with serious health risks that could be fatal. For Pulmonary Hypertension, in only requires smaller doses of Sildenafil by which Revatio is made for. Revatio’s largest dose is 20mg and it is taken 3 times a day with an interval of 4 hours in between each use. The intake of Revatio should not exceed the prescribed dosage of the patient’s physician and the interval lengths in doses should also be observed.

To get the best out of Sildenafil, it should be taken with one full glass of water before meals. Patients should also abstain from eating fatty foods with the medicine so the body will be able to absorb the drug a lot easier. Acidic foods should also be avoided as they decrease the drug’s effectiveness. Grapefruit and grapefruit juice also don’t go well with Sildenafil as it negates the effect of the drug. Consuming alcohol with the drug is also not recommended since it makes the blood thinner, decreasing the blood pressure even more and causing adverse results to the health. It also reduces the blood that stays in the penis so if Sildenafil is taken for ED, it will also lose its effectiveness.

Sildenafil 20mg Price

Sildenafil is still an expensive drug if we are talking about the branded ones. Viagra and Revatio are pretty expensive compared to their generic Sildenafil versions. Before, customers have no other options available since Viagra and Revatio are the only brands of Sildenafil that can be sold at local pharmacies. This is because Pfizer has managed to lock the US market out from any competition that may sell other Sildenafil brands. Pfizer was able to do this by securing their patent rights to Sildenafil through some legal process. But now that it has already run its course and expired, the generic brands are now available for customers to purchase all over the US.
