Sildenafil 20 Mg Vs Viagra

Sildenafil 20 Mg Vs Viagra

Description

Both Viagra and sildenafil are widely used to treat erectile dysfunction. In fact, they contain the same active ingredient. Viagra is a brand name for the sildenafil produced and sold by the company Pfizer. Sildenafil is also sold as a generic drug, which is medically identical to Viagra.

Why it's used

Sildenafil oral tablet is used to treat ED and PAH. Generic oral tablets are available for both conditions, but the brand-name drugs each treat only one of the conditions.

Viagra: This drug is used to treat ED. With ED, you’re unable to get or maintain an erection.

Revatio: This drug is used to treat PAH. With PAH, the blood pressure in your lungs is too high. Your heart has to work very hard to pump blood into your lungs.

How it works

Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Effectiveness

Viagra has been proven to be a very effective treatment for erectile dysfunction with over 80 percent of men finding it works for them. Sildenafil is produced by several manufacturers and contains the exact same medical ingredient and dosage as the branded Viagra counterpart. To receive market approval, a generic medicine must be ‘bioequivalent’ to the branded product which ensures that the generic product has the same effectiveness.

What drugs interact with Cialis and Viagra?

The breakdown and elimination of tadalafil from the body may be decreased by erythromycin, ketoconazole (Nizoral), itraconazole, indinavir (Crixivan) and ritonavir (Norvir). Therefore, these drugs may increase the levels of tadalafil in the blood. If these drugs are being used at the same time as tadalafil, the dose of tadalafil should be reduced to 10 mg every 72 hours when used as needed or 2.5 mg when used daily in order to avoid side effects from high levels of tadalafil.

Rifampin, carbamazepine phenytoin, and phenobarbital may decrease blood levels of tadalafil, possibly reducing the effect of tadalafil.
