Viagra is the trade name for a drug called Sildenafil. Viagra is one of a class of drugs known as PDE-5 (Phosphodiesterase type 5) inhibitors. Viagra and the other PDE-5 inhibitors can help men with erectile dysfunction (male impotence) by enhancing the erectile response when a man is sexually stimulated. Aside from Viagra, the other drugs in this class are Cialis (Tadalafil) and Levitra (Vardenafil). Viagra does not cause a man to be sexually aroused. Viagra is only effective if you are sexually aroused. To understand how it works you need to understand the mechanics of how a man gets an erection. It’s important to learn how Viagra works for a number of reasons — not least of which is that if you don’t learn how it works, you could actually make yourself sick (or worse) by taking it. That’s one of the theories behind why Viagra remains ‘prescription only’ in America; although sadly there are probably more commercially- orientated reasons. All in all, Viagra and its competitors are pretty safe drugs to take; and some people even think that the heart health benefits it provides (remember, sildenafil was originally researched as a drug to treat high blood pressure and angina) mean that we’ll all be taking small, daily doses in a few years, like some people do with Aspirin. In the human body, one of the most important triggers of an erection is c GMP, or Cyclic guanosine monophosphate. This is a cyclic nucleotide which triggers the body to relax smooth muscle tissue, widen blood vessels and increase blood flow. In a suitably aroused man, this provides an erection. The enemy of erections is an enzyme called c GMP-specific phosphodiesterase type 5.

Traveling with prescription drugs is a simple process, provided you pack them properly and keep them safe. Here are some things to consider when traveling with prescription drugs. You will need enough doses of each of your prescription drugs to last for your entire trip, plus several extra doses in case you are delayed while traveling. Talk with your doctor if your insurance provider will not issue extra doses to you. Your doctor should be able to work with your insurance company to get you the extra medications you need. If you take any over-the-counter medications, be sure you have enough of them on hand, too. Certain types of prescription drugs are illegal in some countries. For example, you cannot bring amphetamines or methamphetamines into Japan, even in prescription form. Sildenafil is a medicine used to treat erectile dysfunction. It increases blood flow to the penis to help men get an erection. At least two-thirds of men have improved erections after taking it. Sildenafil is also sometimes used to treat pulmonary hypertension (high blood pressure in the blood vessels that supply the lungs). This medicine is available on prescription and can also be bought from most pharmacies. It comes as tablets that you swallow, chewable tablets, and as a liquid that you drink. Sildenafil for erectile dysfunction (Viagra) can be taken by men aged 18 and over. Sildenafil for pulmonary hypertension (Revatio) can be taken by adults and children aged 1 and over. Do not take sildenafil if you: You can get sildenafil on the NHS if you have erectile dysfunction or pulmonary hypertension.
