    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. April 10, 2000 (Mill Valley, Calif.) -- In his early 40s, Ron Hanson was too young to be having trouble getting and sustaining erections. But like many men, he was too embarrassed at first to talk about the problem. Hanson (not his real name) waited seven years to see a urologist. By the time he spoke up, erectile dysfunction had become a household word, thanks to the popularity of the drug Viagra. But the widely touted drug, Hanson soon learned, doesn't work for everyone. When Viagra (sildenafil) hit the market in 1998, some men thought it was the long-awaited answer to their problems. According to the Grey Clinic in Indianapolis, which specializes in erectile dysfunction, 17% of men between 18 and 55 experience occasional impotence, while 6% have regular erectile difficulties. For men over 55, that number jumps to about one in three.

    The length of time Viagra lasts for will vary from person to person, but it can work for up to 5 hours at a time. This doesn’t mean you will have an erection for 5 hours, it means you will be able to get them easier during this time. Most men will find, that the effects of the pill will start to wear off 2 to 3 hours after first taking it. There are some things that will affect how long Viagra will last for in your case. These are listed in the “What will affect how long Viagra lasts for? To make sure Viagra lasts as long as it’s supposed to, you should always give correct information about your current and past health, and details of any medications you are currently taking when starting a course of treatment with Viagra. One study showed that an hour after taking Viagra for erectile dysfunction, men were able to get erections that lasted 33 mins on average. This dropped to 23 mins if they’d taken it 8 hours beforehand and 16 mins if they took it 12 hours beforehand. Getting an erection involves your heart, blood vessels, hormones, nerves, and even your mood to be in harmony. But essentially erections mostly boil down to increasing blood flow to the penis and trapping that blood flow in special erectile tissues in the penis. Eventually, this trapped blood gets released, the erection ends, and blood flow returns to normal. Viagra works by interfering with the process that lets blood leave an erect penis. PDE5 is the enzyme that’s responsible for “turning off” erections. It works by relaxing muscles and veins in the penis enough to let blood flow return to normal. If an erection lasts more than a few hours it can damage the penis. (That’s why ED medication has a warning about erections “lasting longer than 4 hours”).

    No — it just prevents you from knowing that you have it, says Patrick C. D., who worries that men taking this drug might be dealing with bad information. Even worse, he adds, taking finasteride might mask the signs of aggressive curable prostate cancer until much later. “Many of my patients have asked me about an article that was in the New York Times,” says Walsh, University Distinguished Service Professor of Urology. The article appeared on the newspaper’s front page on Sunday, June 15, 2008, and the spin on finasteride — that it somehow helps men by preventing them from knowing they have prostate cancer, so they can avoid the potential side effects of treatment — was, in Walsh’s opinion, a disaster. The trouble with finasteride, he says, actually dates back to 2003, when the original article was published in the New England Journal of Medicine. The authors of that article studied 18,000 men who randomly were assigned to receive either 5 mg of finasteride (then used mainly to treat benign enlargement of the prostate; men also use it under the trade name Propecia as a treatment for hair loss) or a placebo. The men in the finasteride group had a 25-percent lower risk of being diagnosed with prostate cancer — but a 68-percent higher risk of being diagnosed with high-grade disease (a Gleason score of 7 to 10; this kind of cancer is generally more difficult to cure).

    Phenergan tablets and elixir contain the active ingredient promethazine hydrochloride, which is a type of medicine called a sedating antihistamine. Histamine is a substance produced by the body as part of its defence mechanisms. These can include inflammation in the nose or airways, rashes, and itching of the skin, eyes, nose or throat. Promethazine blocks histamine from binding to its receptors in various parts of the body and this stops it causing the symptoms of an allergic reaction. Promethazine also blocks histamine receptors in an area of the brain called the vomiting centre, which is responsible for causing feelings of sickness and for the vomiting reflex. It is activated when it receives nerve messages from the vestibular apparatus in the middle ear. The vestibular apparatus provides constant feedback to the brain about our body position. When something disturbs the vestibular apparatus, such as movements of the head when travelling by boat or car, nerve signals are sent from the vestibular apparatus to the vomiting centre. This can cause the symptoms of motion sickness, such as nausea, dizziness or spinning sensations (vertigo) and vomiting. Can i buy phenergan over the counter uk 2013 - How can i buy.
