Viagra vs Revatio – What Is the Difference?

Viagra and Revatio are both highly potent health remedies. Sildenafil as an active ingredient is used to treat erectile dysfunction (ED) in men and pulmonary arterial hypertension (PAH).

What’s your health condition? What should you know before taking any of the drugs? Can you mix certain medications? This is the case of Revatio vs Viagra. Although they have the same active ingredient, some precautions must be adhered to.

This guide contains pointers on how to safely take sildenafil for ED and PAH as well as a summary of the best online vendors selling these medications. Let’s acquaint ourselves with what’s necessary for the use of Viagra and Revatio.

What Exactly Is Revatio?

Pfizer is the maker of sildenafil. It discovered that this active ingredient could be used as a potent remedy for PAH. After numerous clinical trials, it showed a higher success rate in treating chest-pain related conditions.

It was approved by the FDA in 2005 as Revatio, marketed as a potent treatment for pulmonary arterial hypertension. It effectively improves exercise capacity in men and women and delays the worsening of the disease.

PAH is a rare, progressive disease that affects the lungs. It is characterized by high blood pressure in the lungs and causes symptoms such as dizziness and shortness of breath. This condition generally affects young and otherwise healthy individuals and normally strikes women twice as frequently as men. Also, every year, between 10 and 15 people per million population are diagnosed with PAH conditions. With improved treatments and survival, the number of U.S. patients living with the disease has increased to between 10,000 and 20,000 [1].

Revatio is a phosphodiesterase-5 (PDE5) inhibitor. PDE5 is an enzyme in the human body that is present in the smooth muscle of the arterial wall within the lungs. When hypertension occurs in the lungs, the heart’s mechanisms must work harder to pump enough blood through the lungs for adequate circulation in the body. As a remedy for PAH, sildenafil in Revatio works on the PDE5 enzyme in the lungs. It acts to dilate (or widen) the walls of the arteries, increasing blood flow and reducing the strain on the heart. Decreasing high blood pressure in the lungs allows the patient’s heart and lungs to work better and consistently improves the individual’s ability to exercise.

I'd had a few unsatisfactory sexual experiences of late. "I'm too young/healthy/horny to be having these problems", I'd said to myself. So after browsing the internet for options. "Free Trial Pack" sounded like just the thing for me. So I placed my order. Normally on first sexual encounters, I am nervous and tentative (knowing I have had troubles before), but this time I was locked and loaded and extra confident. The pill worked. I was as "ready" as I'd ever been. We had a great time, a few times, and she calls me up for a visit quite often now. If you think you could use a boost, give it a try. No complaints here.

Full Information About Viagra

Was this medication a discovery? Certainly! Pfizer researchers en route to testing the most potent PAH remedy – sildenafil (the brand name Viagra), in clinical trials discovered that it could also be used to treat ED.

Those enrolled were getting a quality erection during sexual stimulation compared to their usual erection. Pfizer realized that Viagra could be a breakthrough medication and headed on to patent it.

In 1998, the FDA approved Viagra’s efficacy and safety as a potent remedy for ED. It also became the first treatment to be approved before its approval for PAH. Since then, millions of men have been prescribed with Viagra, thus making it the first, famous, and popular ED remedy.

Difference Between These Pills

It can be easy to confuse the active ingredient found in Viagra and Revatio. Although these drugs are marketed to treat different health conditions, they both contain the same primary ingredient — sildenafil. Both meds are also produced by the same approved manufacturer, Pfizer.

Viagra and Revatio are part of a family of drugs called PDE5 inhibitors. They work by increasing an important body substance called cGMP in the blood. This causes blood vessels to dilate, which results in different effects depending on the dose of the drug and treatment.

How can you compare Viagra vs Revatio? Here is a comprehensive table depicted the main similarities and differences between these pills:

	Viagra	Revatio
Drug class	PDE5 inhibitor	PDE5 inhibitor
Brand/generic status	Brand and the generic version available	Brand and the generic version available
What form does the drug come in?	Oral tablet	Oral tablet, injection, oral suspension
What is the generic name?	Sildenafil citrate	Sildenafil citrate

Sildenafil (as generic Viagra) has also been shown to help treat women who experience female sexual arousal disorder (or FSAD). This disorder is common in up to 26 percent of American women [2].

Depending on your health condition, Revatio or Viagra may be prescribed after a doctor assess your health. Talk to your medical specialist to find out which remedy may work better for you. Since they both contain the same ingredient, you may be prescribed generic sildenafil in most cases.

Where to Buy Viagra and Revatio?

PureRxPills.com

PureRxPills is another excellent e-pharmacy, but it doesn’t offer Revatio and stands out from the mentioned ones. As stated on its website, it isn’t exactly an online drugstore.

To get drugs from this vendor, it requires its buyers to fill in some medical information. It’s necessary – especially if you haven’t visited a doctor. This information will be forwarded to a licensed physician to review and make informed decisions. Once your order is reviewed and approved, it will then be dispatched to your shipping address. If your parcel is shipped but doesn’t arrive or is damaged, this pharmaceutical intermediary will either offer you a refund or reship the order, depending on your preference.

Revatio vs Viagra: Dosage

For the treatment of heart conditions such as PAH, the recommended dose of Revatio Oral is 5 mg or 20 mg to be taken three times a day. It is administered 4–6 hours apart. In the clinical trial, no greater efficacy is achieved with the use of higher doses. Treatment with doses higher than 20 mg 3 times a day is not recommended [4].
The standard recommended dose of sildenafil used in Viagra or generics for treating ED is 50 mg, but your medical specialist can prescribe anywhere from 25 mg to 100 mg depending on your ED severity, tolerability, and response to medication.

When anticipating sexual activity, it should be taken 30–60 minutes earlier. Its peak effects are felt in an hour and last for 4–5 hours depending on your metabolism. Taking Viagra with fatty meals may delay the onset of action.

What Side Effects Do These Tablets Have?

Viagra and Revatio cause similar negative effects due to sildenafil contained in both drugs. Although not all of these symptoms may occur. Check with your medical specialist if any of the following common negative effects occur while taking sildenafil:

• bladder pain;
• burning, itching, crawling, numbness, prickling, “pins and needles”, or tingling feelings;
• burning in the stomach or chest;
• dizziness;
• cloudy or bloody urine;
• indigestion;
• pain on urination;
• increased frequency of urination;
• tenderness in the stomach area;
• stomach upset.

This is not a complete list [5]. If treating ED, Viagra has been studied comprehensively in regards to side effects and what you should follow before initiating dosage including important safety information and indication [6].

Interaction with Other Medicines

Sildenafil is mainly processed by the liver. Therefore, both of these drugs interact with many of the same medicines. Since Viagra and Revatio are processed by CYP3A4 enzymes, they should not be used with other meds that affect how these enzymes work. CYP3A4 inhibitors can increase the level of sildenafil in the blood and cause adverse negative effects.

Other drug interactions include:

• nitrates;
• antihypertensives;
• HIV protease inhibitors;
• alpha-blockers;
• medicines that treat high blood pressure;
• other drugs containing sildenafil or any other PDE5 inhibitors.

Do not take these meds together as this can increase the risk of hypotension or dangerously low blood pressure. This is not a comprehensive list of all possible drug interactions. Consult a medical specialist with all the medications you may be taking as well as to assess your health. It’s not good to take sildenafil if you have certain health problems.

Resume

Revatio, as a PAH remedy, contains the same active ingredient as Viagra for ED. Both medications can help treat different conditions depending on the dose given. Revatio by Pfizer comes with sildenafil at a lower dose, while Viagra tablets contain this component in higher doses. Both drugs should not be taken at once.
