2. How Does raw Sildenafil powder Works?

Sildenafil is a prescribed medicine commonly used treat erectile dysfunction (ED). In the in the 1990s, a drug manufacturer brought this medicine to the market as a treatment for men who experience ED. However, it was not initially created to treat such condition but to treat pulmonary arterial hypertension, a serious heart and lung condition.


Sildenafil , an active ingredient used to increase blood flow in particular parts of the body, in case of men with ED, in the penis.For men to get and sustain erection during sexual activity, the penis needs nitric oxide (NO). But men of certain age and condition do not naturally and normally produce enough nitric oxide, thus slowing down the blood flow. 

When this happens, the penis softens during the activity. Sildenafil  which is the main ingredient of Revatio helps the body regulate blood flow and assists you in producing nitric oxide to keep you going.


After you have used Sildenafil, and after you have had sexual relations while using Sildenafil - your erection will go away normally. You will not have to worry about ‘what will I do with this now?’ or ‘how can I tell her I am happy if this won’t go away!’. Sildenafil works with your body to give you the balance you need in your chemistry to allow you to have an erection when you are sexually aroused. Giving your body the chance to absorb the chemical that is lacking in your body to gain an erection is an easy choice! - Just do it.

Sildenafil comes as a tablet and suspension (liquid; Revatio only) to take by mouth.How should this medicine be used?This is a question that everyone concerns,Now let's take Revatio for example:


If you are taking sildenafil to treat erectile dysfunction, follow your doctor's directions and the guidelines in this paragraph. Take sildenafil as needed before sexual activity. The best time to take sildenafil is about 1 hour before sexual activity, but you can take the medication any time from 4 hours to 30 minutes before sexual activity. 

Sildenafil usually should not be taken more than once every 24 hours. If you have certain health conditions or are taking certain medications, your doctor may tell you to take sildenafil less often. You can take sildenafil with or without food. However, if you take sildenafil with a high-fat meal, it will take longer for the medication to start to work.


If you are taking sildenafil to treat PAH, follow your doctor's directions and the guidelines in this paragraph. You will probably take sildenafil three times a day with or without food. Take sildenafil at around the same times every day, and space your doses about 4 to 6 hours apart.Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take sildenafil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Follow the manufacturer's directions to use and clean the oral syringe. Do not mix the liquid with other medications or add anything to flavor the medication.


If you are taking sildenafil for erectile dysfunction, your doctor will probably start you on an average dose of sildenafil and increase or decrease your dose depending on your response to the medication. Tell your doctor if sildenafil is not working well or if you are experiencing side effects.
