Viagra

Viagra is one of the most established erectile dysfunction treatments and it was the first one to go mass market. The medications that were available prior to Viagra were all rather inconvenient for patient self-administration as they involved injections directly into the penis. The most famous one was that devised by Dr Giles Brindley when he injected phentolamine into his penis in front of delegates at a urology conference in Las Vegas, this demonstrating that erectile dysfunction was not psychological but physical.

Viagra is the first in class PDE5 inhibitor and comes in a handy pill so there is no need for an injection into the penis. The medication works by inhibiting the production of an enzyme called PDE5. For an erection to form, the penis needs lots of blood to flow in and for that blood to be trapped there so the arteries expand and the veins constrict. PDE5 destroys the chemical cGMP, which causes the muscles to relax and allow blood to flow into the penis. By inhibiting the production of the enzyme that degrades cGMP, Viagra allows men to maintain an erection.

Erectile dysfunction affects a very large number of men – especially those aged over 40. The penile arteries can narrow with age and this can make it more difficult for erections to form. Erectile dysfunction can be a marker for other underlying conditions, such as cardiovascular disease. It is always good to have a check-up with your doctor rather than just diagnosing yourself and buying Viagra over the internet.

If you are going to buy Viagra or any other medication over the internet then we recommend that you do this after you have a GP check-up. It is possible to save money by buying Viagra over the internet but do you want to risk your health and well-being? We recommend this website that has a helpful comparison between the various websites in the UK that legitimately sell Viagra and its generic version, sildenafil. So long as the Sildenafil is bought from a UK-based company with a Care Quality Commission licence and dispensing from a regulated pharmacy then you will be getting a genuine product.

Please be aware that Viagra can cause side effects and it is not suitable for everyone – this is why it is on prescription.
