    Sildenafil


    Sildenafil is a vasoactive agent used to treat erectile dysfunction and reduce symptoms in patients with pulmonary arterial hypertension (PAH). Sildenafil elevates levels of the second messenger, c GMP, by inhibiting its breakdown via phosphodiesterase type 5 (PDE5). PDE5 is found in particularly high concentrations in the corpus cavernosum, erectile tissue of the penis. It is also found in the retina and vascular endothelium. Increased c GMP results in vasodilation which facilitates generation and maintenance of an erection. The vasodilatory effects of sildenafil also help reduce symptoms of PAH. 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.

    When a man is sexually excited, the penis rapidly fills with more blood than usual. With this extra flow of blood, the penis then expands and hardens. After the man is done having sex, this extra blood flows out of the penis back into the body. In an opposite extreme situation, if an erection lasts for a long time (more than 6 hours), it can permanently damage your penis. You should call a doctor immediately if you ever have a prolonged erection that lasts more than 4 hours. Therefore sexual activity may not be advisable for people who have heart problems. Before you start any treatment for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pains, dizziness or nausea during sex, stop having sex and immediately tell your doctor you have had this problem. This is called erectile dysfunction if it becomes a frequent problem. Erectile dysfunction is a serious problem that can affect both the young and the old, involving psychological causes in some cases. Among other treatments that are nowadays available for erectile dysfunction, Viagra was the first. Some conditions and medicines interfere with the natural erection process. Erectile dysfunction, defined today as the inability to attain and maintain an erect penis with sufficient rigidity for sexual intercourse, has become an increasingly common complaint that affects 140 million men worldwide. So Viagra stands out as the pioneer of drugs that treat erectile dysfunction, for twenty years. Sildenafil citrate was the first oral agent to be introduced for the treatment of erectile dysfunction, thanks to the researchers from Pfizer. Sildenafil is the active substance of Viagra, while Viagra is the commercial name. Teva’s generic Viagra has launched already in December 2017 in the United States. Risk factors for developing erectile dysfunction include age, diabetes, hypertension, obesity, lack of exercise, dyslipidemia, smoking, depression, lower urinary tract symptoms, and pelvic surgery. Sildenafil is a highly selective inhibitor of PDE type 5 and enhances NO-mediated relaxation of human corpus cavernosum. Pfizer recently started to sell the new generic version of Viagra. Sildenafil is a common medication used to stimulate erections in men with erectile dysfunction (ED) and treat certain heart conditions. Many factors can influence how long Viagra takes to start working. In general, Viagra takes about 30 minutes to produce noticeable effects. But your diet, your overall health, the medications you’re taking, underlying conditions, and much more can all affect the amount of time Viagra takes to work in your body and how long it lasts. An erection happens when nerves in your penis are stimulated. Then, muscles around two cylinder-shaped chambers of spongy material along your penis, known as the corpus cavernosa, relax and allow blood to flow in, causing an erection. With ED, your nerves don’t communicate properly with your brain and blood doesn’t flow properly into the corpus cavernosa. Taking Viagra relaxes the walls of your blood vessels and lets blood flow more easily into the parts of your penis that cause an erection. You’ll still need to feel sexually aroused to get an erection.

    DD takes it for travel sickness and we are going away tomorrow and i have just checked the bottle and it is out of date by a few months. Obviously too late to get any on prescription, so wondered if I could get it in the chemist in the station over the counter. TIA Unless something has changed recently then it's not under prescription. HOwever be prepared for a grilling as some people use it for getting their dc to sleep, so make sure you tell them it's for travel sickness. Hmm, our train is at 7.30am and the pharmacy in the chemist opens at 7, so that is really the only one we will have a chance to go to. She is 9, so should be fine with a tablet if they have those. If not, hopefully i will be able to at least get some for the return journey!
