Why You Should Use Sildenafil Tab 20mg

Sildenafil is a drug known by its brand name as ‘’Revatio or Viagra”. It’s medically proven to be effective and reliable in the treatment of erectile dysfunction (ED) in men and in the treatment of high blood pressure in the lungs (pulmonary hypertension) in both men and women. Sildenafil is also a prescription medication which belongs to drug group phosphodiesterase (PDE5) inhibitors.

In men, Sildenafil helps in treatments of erectile dysfunction (sexual impotence). Erectile dysfunction is the inability to harden or expand penis when a man is sexually stimulated or excited. With Sildenafil, it helps to increase blood flow to the penis which leads to an erection.

Pulmonary hypertension occurs in the heart and lungs. When it occurs in lungs, the heart has to enhance pumping of the blood into the lungs. Sildenafil boost the flow of blood by widening and relaxing blood vessels in the lungs where the blood flows through, thus reducing the workload of the heart.
