How Pfizer’s Viagra Works And Erectile Dysfunction Side Effects

Viagra or Revatio or Sildenafil Citrate is a drug from the class of phosphodiesterase type 5 PDE5 inhibitors which was developed by the pharmaceutical company Pfizer in 1996. The Brand name Viagra can be taken orally and in the form of intravenous injection. Normally, this drug is indicated for disorders of pulmonary, hepatic, renal hypertension, and mainly for erectile dysfunction.

Dosage

The tablets are sold in doses of 20 mg (Revatio), 25 mg, 50 mg, and 100 mg (Viagra). Men and women who are pregnant or breastfeeding can take Viagra without threatening their unborn child, but sildenafil (Generic Viagra) is contraindicated in infants or children, and of course, in people with allergies to Revatio. It should be noted that Viagra has side effects. They include, but are not limited to, headaches, epistaxis, insomnia, high blood pressure, erythema, and dyspepsia.
