How does Sildenafil work against High Blood Pressure?

Sildenafil is a phosphodiesterase (PDE5) inhibitor, which means that it stops the activity of the enzyme phosphodiesterase. This enzyme breaks down substances called cAMP and cGMP. 

Cyclic GMP causes the blood vessels or arteries, to relax and widen. Sildenafil decreases the activity of PDE5 so that more cyclic GMP is available for the blood vessels inside the lungs. This leads to the relaxation or widening, of those vessels. 

Relaxing and widening of the blood vessels in the lungs decreases the pulmonary blood pressure to the heart and improves its function. This reduces blood pressure in the lungs which generally results in the ability to be more active. 

What is the usual daily high blood pressure or pulmonary hypertension dosage intake for Sildenafil?  

A medication like Sildenafil should always be taken as per a doctor’s advice after a thorough diagnosis of the patient. 

However, FDA recommended a Sildenafil 20 mg tablet to be taken by a hypertension patient, about three times a day; keeping a 4 to 6 hours gap in between each dose. 

In case this dose fails to reap desired results, doctors might suggest taking it to a maximum of 80 mg three times per day.
