The sildenafil injection is prescribed to treat signs of pulmonary arterial hypertension in healthy adults. This kind of high blood pressure takes place in the middle of the lungs and the heart. When the lungs go through hypertension, the heart must increase its workload to pump an adequate amount of blood. This medication is currently manufactured under the US brand name Revatio.
The sildenafil injection can also aid patients who have erectile dysfunction, but patients interested in this must take the oral route of this medication.
This medication aids the ability of adults with high blood pressure to exercise. Children typically are not prescribed sildenafil.
Sildenafil is a phosphodiesterase 5 inhibitor (PDE5), which is a name for several medications that diminish stress on the blood vessels by working on the PDE5 enzyme within the lungs. This means that the sildenafil injection is highly effective for decreasing the total amount of work for the heart.
The sildenafil injection can only be obtained with a prescription from your doctor.
This medication is only available in the solution form to be injected.
In addition to the desired benefits, medications can occasionally also trigger undesired side effects. While not every side effect may take place, they could warrant medical attention if they do take place.

The sildenafil injection treats symptoms of pulmonary arterial hypertension, the type of high blood pressure that occurs in the middle of the heart and the lungs. When the lungs undergo hypertension, the heart must, therefore, increase its total expended workload to pump an even greater amount of blood. Sildenafil helps adults with high blood pressure in their ability to exercise, as it takes pressure off of the heart. Exercise is highly important for adults, and those with high blood pressure may benefit from considering sildenafil for this purpose. You should consult with your physician to determine if this drug is the most optimal form of treatment for you.
