As men age there are many changes to their body. Things often don’t work like they used to when they were younger. A common fact for many men is that as they age, they suffer from Erectile Dysfunction (ED) – that is – the inability to have and/or maintain an erection. This condition can have many effects on men both physically and psychologically. Physicians offer various types of treatment – one of these being medication. Probably the most commonly known for of drug treatment for ED is Viagra.
Viagra is the most popular brand name for the drug sildenafil citrate. It is marketed today by the pharmaceutical company Pfizer, and is also sold under the name Ravatio and Caverta in certain parts of the world. Viagra is designed to treat erectile dysfunction, or ED. It comes in the form of a blue pill in 25mg, 50mg, and 100mg dosages. Many websites have Viagra for sale after filing out a short questionnaire, although it is available mainly through ones physician. The drug Viagra was designed in the 1990s with the intention of treating a form of cardiovascular disease known as angina pectoris. Though it was not found effective for its original intention, researches of the drug remarked on its ability to induce erections in male study participants. It was then patented in 1996 with the intention of development as a treatment for ED. By 1998 it had passed the necessary tests for FDA approval, and hit the market with immediate and large-scale success. Many men – not only the aged – suffer from Erectile Dysfunction at some stage of their lives. Whilst many of the main causes are psychologically caused, a few are caused by physical injuries or irregularities. For men who suffer from ED but are otherwise in good health, medication such as Viagra may be very effective. For others, whose ED is caused by damage or injury, they may find that medication has no effect. Viagra is classified as a PDE5 inhibitor. PDE5 causes a compound called cyclic GMP or cGMP to degrade. Since cGMP causes the arterial smooth muscles in the penis to relax, allowing the penis to fill with blood and become erect, inhibiting the action of PDE5 will lead to penile erections so long as the individual is otherwise healthy. Some other PDE5 inhibitors available today include Levitra, and Cialis. There may well be side effects of Viagra, the most common include headache, stomach upset, flushing, and sweating. Occasionally, users of Viagra experience blurred vision, and in some rare cases have reported temporary lose of sight in one or both eyes. Viagra should not be taken in conjunction with drugs designed for angina pectoris, as together they can induce a dangerous drop in blood pressure. People who use the internet and email will be all too aware of the number of spam emails that are received from all around the world from people selling Viagra over the internet. It is always sound advice to seek medical opinions from you medical provider before taking any medication. |
