Viagra 150 mg

Normally a Viagra 150 mg tablet contains the ingredient Sildenafil Citrate which relaxes the muscles present in the walls of the blood vessels. It works by increasing blood circulation to specific body parts, including the penis. When an individual is sexually stimulated, Nitric Oxide is released which is responsible for the production of cGMP that controls the dilation and contraction of blood vessels.

An enzyme known as PDE 5 destroys the cGMP. Viagra 150 mg blocks the action of PDE 5 and allows cGMP to be produced properly. Hence, Viagra (sildenafil) is a PDE 5 inhibitor drug. A few other drugs categorized in the same group are vardenafil (Levitra), tadalafil (Cialis), avanafil (Stendra), etc. These drugs allow the blood to flow easily to the penis. As more and more blood flows to the penis, an erection is much easier to be achieved and maintained further.

The recommended dosage of Viagra (sildenafil) for erectile dysfunction (ED) treatment is 50 mg, taken as needed about 1 hour before sexual activity. And you should only take one dose a day. After using the Viagra 50 mg dose, you should inform your doctor about how your body responded to the medication. This includes whether your erectile function improved or not. Depending on how Viagra medicine worked, your concerned doctor may suggest optimizing by decreasing your dose to Viagra 25 mg or increasing it to Viagra 100 mg.
