The pharmaceutical industry has products of similar substances that work for different causes and has different effects on the human body. Revatio and Viagra are made of the same ingredient: Sildenafil. They are manufactured by the same company – Pfizer. They also come under the same family of drugs – Phosphodiesterase-5 (PDE type 5) inhibitors. Revatio and Viagra are simply administered at unique doses as they treat different conditions, although via the same route.
Revatio is used to treat Pulmonary Arterial Hypertension (PAH), whereas Viagra is widely used to Erectile Dysfunction (ED). Viagra has been the original brand name of Sildenafil that is used to increase blood flow in the penis and other parts of the body.
Revatio is available as tablets, injections, and oral suspension. The tablets usually have a 20 mg dosage that is administered 3 times a day at a lower dose. The injection has a 10 mg / 12.5 ml dosage. The oral suspension is taken with a combination of 1.57 g of sildenafil citrate, 90 ml of water and a 2 ml oral syringe, giving a total of 112 ml. It stays in the body for up to 4 hours and reaches its peak effects within one or two hours of consumption.
Viagra is taken 30 minutes to four hours before sexual activity. It is taken in a relatively higher dosage starting from 25 mg to 50 mg up to 100 mg. It should be taken only once per day. Stays in the body for four to six hours. Ideally, consume Viagra 30 minutes to an hour before sexual activity to ensure you are hard only when it matters most.
Revatio can have some adverse effects such as diarrhea and nasal congestion. Whereas Viagra may contribute to back pain, abdominal pain, and rashes.
Revatio and Viagra are used to treat different conditions. But the primary ingredient Sildenafil is processed by the liver. Therefore, Revatio and Viagra are processed by the same CYP3A4 enzymes. They should not be used with other drugs without proper consultation with the doctor.
Sildenafil’s primary function is to relax and widen the blood vessels, which results in increasing the blood movement to the particular part of the body depending on whether it is Revatio or Viagra.
Revatio works by relaxing the muscles and opening up the blood vessels in the lungs which decrease the blood pressure in the lungs. Arteries become wider and the clogged plaque begins to clear up and normalize blood pressure to the heart. It increases the ability of the body to exercise itself.
Viagra works to attain and maintain an erection of the penis by increasing the blood flow to the penile structure. Keep in mind, Viagra works for erectile dysfunction only if sexually aroused.
Revatio and Viagra cannot be used for alternate purposes as the dosage and constituents vary. Interactions of other medicines, drugs, and vitamins might change the way the drug works. Hence, a medical professional must be consulted before you consume either of these medicines.
Taking these drugs along with Sildenafil will cause the blood pressure to drop to a fatally low and unsafe level, leading to possible coma or cardiac arrest.
The consumption of alcohol while on medication of Sildenafil might increase the risk of low blood pressure. More than 2 small drinks will also reduce the effects of the medicine. Therefore, alcohol consumption (while consuming Viagra or Revatio) without the doctor’s approval should not be done.
Depending on the medical condition, Revatio and Viagra are used as generic medicines. It is important to consult the doctor before the intake of any of these two drugs as they can lead to adverse health risks. These drugs should not be used for treating alternative medical conditions. The dosage must also be provided with precautions, especially in the case of an oral suspension of Revatio. Another point that is good for your knowledge of such blood pressure tablets is the pricing – Viagra is more expensive as compared to Revatio. But these are amongst the top 3 medicines for treating clogged arteries and erectile dysfunction.
