News Story Article Report:
This is what The UKMedix medical team had to report:
We truly do live in an age of medical miracles. Modern medicine has
evolved to the point at which it is finally possible to remedy health
challenges that have plagued Mankind, literally since our earliest days as
a species. One of the most significant of these achievements has been
the discovery of a treatment for sexual impotence in males, clinically
referred to as Erectile Dysfunction (ED). In 1998, after extensive
research and clinical testing, the Federal Drug Administration approved the
Pfizer company's application to market an ED treatment drug named
Viagra (sildenafil citrate).

To understand how Viagra works, one first has to understand the mechanics of how an erection develops. The process starts when specific hormones cause the body to release Nitric Oxide (chemical symbol - NO) into an area on the underside of the penis called the corpus cavernosum. The Nitrous Oxide activates an enzyme named Guanylate Cyclase, which then creates locally increased levels of Cyclic Guanosine Monophosphate (cGMP) producing smooth-muscle relaxation. This process allows blood to fill the corpus cavernosum with blood and the penis then becomes erect. Viagra acts to specifically inhibit the enzyme phosphodiesterase type 5 (PDE5), which enhances the normal interaction of NO/cGMP. In short, Viagra simply facilitates normal processes in the bodies of men whose bodies are either producing too much PDE5 or too little NO. Viagra is available in 25mg, 50mg and 100mg dosages by prescription only. It is unlikely to be available over-the-counter (OTC), meaning without a doctor's prescription, at any time in the foreseeable future because of the dangers of possible side-effects. Known minor side-effects include headache, flushing, nausea, stuffy or runny nose, urinary tract infection and diarrhea. A small number of men, about 3%, have reported the loss of sight in one eye (non-arteritic anterior ischemic optic neuropathy, acronym - NAION), caused by the sudden loss of blood supply to the optic nerve. A similar number of men reported the "seeing blue" phenomenon, in which they said they saw everything with a blue tint and sometimes experienced an accompanying sensitivity to light. Men who are at increased risks for these side-effects include those who have heart disease, are over 50 years old, have diabetes, have high blood pressure, have high cholesterol, smoke and or have certain eye problems. It is especially important that patients have extended and frank discussions with the prescribing physician to review ALL of the other medications the patient may be taking and any recreational drugs that may be involved, especially Amyl Nitrate (aka "poppers").
