Sildenafil 20 mg Review – Generic Sildenafil vs Viagra

Sildenafil 20 mg is also known as Revatio from Pfizer. It has the active ingredient Sildenafil Citrate, much like the active ingredient of the famous drug Viagra from the same company, Pfizer. These drugs have identical active ingredients but interestingly have different functions.

What Is Sildenafil 100 mg and How Is It Different from Sildenafil 20 mg?

Sildenafil 100 mg and Sildenafil 20 mg are identical in terms of active ingredients—Viagra and Revatio have the same active contents and they work similarly in the body. Revatio or Sildenafil 20 mg is indicated for the treatment of patients suffering from pulmonary arterial hypertension (PAH); on the other hand, the drug Sildenafil 100 mg or Viagra (also Sildenafil 25 mg or 50 mg) is indicated primarily for the treatment of erectile dysfunction in the patients.

Although pulmonary hypertension and impotence are two different medical conditions, Sildenafil Citrate—in varying amounts—is able to treat both medical conditions effectively. This is because both medical conditions involve the same phosphodiesterase type 5 enzyme responsible for both diseases. This same enzyme is also responsive to Sildenafil Citrate treatment, making both Revatio and Viagra effective for both medical concerns.

Here are some of the key traits of Revatio (Sildenafil 20 mg) and Viagra (Sildenafil 100 mg, 50 mg, or 25 mg):

Similarities:

  • Both drugs have the same active ingredient Sildenafil Citrate
  • Regardless of dosage, the Sildenafil Citrate in both drugs lasts an average of 4 hours in the body
  • Both Sildenafil 20 and 100 mg are prescription only products
  • Since they have the same active content, the mechanism of action of these drugs are the same – they encourage vasodilation and smooth muscle relaxation in tissues with the phosphodiesterase enzyme

Differences

  • These products are indicated for different medical conditions
  • Viagra does not have an intravenous form
  • Viagra is taken only once a day, while Revatio and its generic equivalents are taken three times a day
  • Sildenafil 20 mg dose for PAH in patients is weight-dependent – Viagra for impotence dose is not

Since these drugs are both prescription-only, make sure to take these products only under the advice of your physician/s.

How to take Sildenafil 20 mg: What are the dosage instructions for Sildenafil?

How should patients take Sildenafil 20 mg for pulmonary arterial hypertension? According to drug information for Revatio (Sildenafil 20 mg), the prescription recommendation for its tablet and oral suspension form is anywhere from 5 mg to 20 mg, three times a day, as directed by the doctors. On the other hand, its intravenous form is taken anywhere from 2.5 mg to 10 mg three times a day, since the IV form is equivalent to double the amount of the oral forms for the same drug.

As for patients with erectile dysfunction, the recommended dosage for Viagra and its generic alternatives is usually 25 mg to 100 mg; however, depending on the severity of the impotence or depending on the tolerance of the patients for the medication, doctors can advise doses lower than 25 mg or greater than 100 mg. Viagra and generic Viagra products are not taken daily—they are only advised as needed and only once in a day. Viagra is recommended to be taken at least 30 minutes before any sexual activity.

Special considerations:

  • Not all patients can take Sildenafil Citrate. In some cases (usually in patients with liver disease, kidney failure, and cancers), Sildenafil is ill-advised; however, doctors can give an optimized dose to patients with the aforementioned diseases if the benefits of Sildenafil Citrate exceed its risks.
  • Some groups of medicines should not be administered with Sildenafil, like nitrates, blood pressure lowering medicines, alpha blockers, some antifungal medicines, some antibiotics, and liver medicines.
  • Sildenafil should not be taken with alcohol or grapefruit juice.
  • According to most patients, Sildenafil Citrate is faster-acting when taken on an empty stomach.

Sildenafil 100 mg Side Effects: Are they the Same with Sildenafil 20 mg Side effects?
