Viagra Action

Viagra treats erectile dys function and works by relaxing muscles and increases blood flow to particular areas of the body (in this case, the penis, specifically). Its effects last up to four hours. The most common side effects of Viagra are headache, facial flushing, and upset stomach. Rarely, blurred vision, or sensitivity to light may briefly occur.

As well as treating impotence, Sildenafil Citrate can also be effective in treating Pulmonary Arterial Hypertension (PAH). Similarly to how it acts to relax muscles of the penis, it relaxes arterial walls; therefore, reducing resistance and pressure in the arteries.

Sildenafil Citrate is solely active in relaxing muscles and increasing blood flow to the heart, lungs and penis due to PDE-5, yet vasodilation is not increased in other parts of the body.



1. Erectile Dysfunction ( Viagra only)


PO 50 mg once, 0.5 to 4 h prior to sexual activity. Titration to a 25 or a 100 mg dose may be used based on tolerability or efficacy. The max recommended dosage is 100 mg per day and max recommended frequency is once daily.

2. Dosage Adjustments ( Viagra only)


PO Consider a starting dose of 25 mg in patients older than 65 yr of age, or in patients with hepatic impairment, severe renal impairment, or concurrent use of potent CYP3A4 inhibitors (eg, erythromycin, itraconazole, ketoconazole, saquinavir).

3. Alpha-blockers
Patients should be on stable alpha-blocker therapy prior to initiating treatment and should be initiated on sildenafil at the lowest dose.

4. Protease inhibitors

Do not exceed a max single dose of sildenafil 25 mg in a 48-h period.

Pulmonary Arterial Hypertension ( Revatio only)
PO 20 mg 3 times daily. IV 10 mg (12.5 mL) administered as a bolus injection 3 times daily.
