20mg Sildenafil: The World’s First Successful Drug in Treating Erectile Dysfunction

Sildenafil is the world’s first successful drug in treating Erectile Dysfunction. Pfizer released the iconic brand Viagra back in ’97 and the way people perceive ED has changed forever ever since then. Sildenafil is also used in treating Pulmonary Arterial Hypertension (PAH) and for that, Pfizer released Revatio, their second Sildenafil product line after Viagra. For ED, Sildenafil medication is only taken when needed, strictly once every 24 hours. For Pulmonary Hypertension, 20mg Sildenafil is taken three times a day with 4 hours interval in between intakes, to keep the ailment at bay.

But how does this drug work and how does it function in the body? Is it safe, does it have negative effects as consequences of use? In this brief article, we will learn about the workings of Sildenafil and other important things concerning this drug.

Revatio 20 Mg

Sildenafil is an inhibitor-type drug that works in the body by inhibiting the enzyme called Phosphodiesterase 5 or PDE5, causing the dilation of the blood vessels and other blood passageways resulting in an improved blood circulation. The muscles surrounding the blood vessels are relaxed, reducing the pressure and allowing a more fluid blood flow inside the body. This action of Sildenafil works in ED by supplying the formerly limp penis with an increased and constant blood flow, making sustained and stronger erections possible. This effect of Sildenafil to the male reproductive organ is much better than the normal erections since its length of effect lasts 5 to 7 hours.

Pulmonary Arterial Hypertension is dealt by Sildenafil in the same way. After the patient’s ingestion of the drug, Sildenafil works by enlarging the diameter of the arteries temporarily making the blood circulation easier and reducing the dangerous levels of blood pressure to normal.

This drug should only be taken upon the advice of a physician or a healthcare professional as wrong use of this medication carries tremendous risks to the health. The doctor should know the patient’s complete medical history before starting them on this medication as there are certain health conditions where this drug can be dangerous if used. Other blood pressure lowering medicines such as nitrates should also be avoided when taking this drug since it causes a significant decrease in the user’s blood pressure that could prove fatal. Sildenafil itself is 100% safe as guaranteed by the United States Food and Drug Administration but its use should strictly be under the recommendation of a physician.
