And the drug may have potential for treating several other conditions, according to a recent report.

The three ED medications currently on the market—Viagra, Levitra, and Cialis—all work by the same means, and they have similar side effects.

The most common are headaches and facial flushing, which occur in 15% of men. Other reactions include nasal congestion, indigestion, and back pain.

The most important worry about ED pills is their ability to widen arteries enough to lower blood pressure. And men who are taking nitrates should never use any of the ED pills.

Although some of the drugs’ side effects may be troublesome, others may be helpful, and scientists are studying whether ED pills might help treat a variety of nonsexual problems. Viagra (sildenafil) has been on the market longest and is most studied.

It’s yet not clear if the other ED pills offer similar benefits, but Viagra, at least, may prove useful for some other conditions, including these: Pulmonary hypertension.

Viagra is now marketed under the name Revatio for this uncommon but serious disorder of high pressure in the blood vessels leading to the lungs.

Viagra can reduce pulmonary artery pressure at high altitude and improve the ability to exercise in low oxygen conditions.

In affected individuals, exposure to the cold triggers spasm of the small arteries that supply blood to the fingers, toes, or both, which become pale, cold, and painful.

Both Viagra and Levitra have been helpful in clinical trials.

Studies suggest Viagra might help patients with congestive heart failure or diastolic dysfunction. Further details are published in the August 2007 issue of Harvard Men’s Health Watch. Give guidance, not just Viagra, to men with diabetes and related impotence.

Diabetic men with erectile dysfunction might consider a prescription for a drug like Viagra to be a permanent cure for a temporary issue: Take a pill, problem solved. But the truth, a leading urologist says, is entirely different. “If a diabetic patient has erectile dysfunction, it’s not enough to provide Viagra [sildenafil] or cialis soft generico 20 mg Cialis [tadalafil] and then send him on his merry way,” J. Francois Eid, MD, a New York City urologist, said at the annual meeting of the American Association of Diabetes Educators. “It’s important to let individuals know the drug has not cured the erectile dysfunction.

If patients don’t take care of the diabetes, the erectile dysfunction progresses.” In an interview, Dr. Eid shared several messages for medical professionals who treat men with diabetes and related erectile dysfunction: • Diabetes has “devastating” effects on the penis, and may even cause it to shrink.

• Long-term uncontrolled diabetes can make ED permanent.

• While ED drugs often fail in men with diabetes, several other options exist; and penis implants may provide significant relief. An estimated 50%-75% of men with diabetes experience from some degree of ED, which is thought to be three times more common in diabetic men than other men, according to Dr.

“Diabetes has a devastating effect on the muscle tissue inside the penis,” he said. “All the tiny little arteries that feed blood to the muscle get occluded. Little by little, the muscle inside the penis shrinks.” Indeed, some diabetics with ED complain that their penises have shrunk, he said.

Diabetic damage doesn’t stop with these small vessels, he said.

“You really have two parallel situations: You need blood flow that feeds the muscle of the penis, and you need an artery dedicated to bringing blood rapidly when a man becomes aroused and wants to be sexually active,” he said.

They’ll say ‘I can get a partial erection, but I can’t maintain it.’ ” What comes after an ED diagnosis in diabetic patients? Eid will instantly refer these men to a cardiologist. “If a patient has diabetes and is newly diagnosed, a significant portion of these men are going to develop coronary artery disease in the next 2-3 years,” he said.

“One of the things we do is recommend is that they see a cardiologist and perhaps have a stress test or some sort of evaluation.” Dr.

Eid also urges these patients to treat their diabetes in order to avoid developing ED for life.

“They need to manage their diabetes and make sure they control it so the ED will not progress and will stabilize, as a result,” he said. “If the diabetes is controlled after the patient is first diagnosed, then the erections will come back.

But if the patient has diabetes for many years, and suddenly decides it’s time to control it, they cannot prevent the damage that’s already been done.” As for treatments, patients with diabetes and related ED should begin with medications like sildenafil and tadalafil, he recommended. But research findings suggest that the drugs will fail in half of men with type 2 diabetes, he said.

Other options include penile self-injections, vacuum devices, and penile implants.

The injections “can work well and are painless, but men detest having to inject themselves before sexual activity,” Dr. And he said men rarely have success using vacuum devices, which are available over the counter.

By contrast, penis implants can successfully treat erectile dysfunction in many cases, Dr. Men trigger erections by squeezing a pump that is implanted into the scrotum.

Fluid then flows from an implanted reservoir into a cylinder implanted in the penis. Men are often pleased by penis implants because they can have sex spontaneously without having to plan for it ahead of time, as required by medications.

Sildenafil Treats Urinary Symptoms of BPH as well as ED.

ATLANTA—For the first time, an oral phosphodiesterase type 5 (PDE-5) inhibitor has been shown to improve lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH) in men with concomitant erectile dysfunction (ED), according to data presented at the annual meeting of the American Urological Association. Results of this study in men (aged ?45 years) with ED and concomitant lower urinary tract symptoms showed that if taken daily, sildenafil (Viagra) was comparable to alpha-1 blockers in improving the International Prostate Symptom Score (IPSS) in these patients. “This is the first study of its kind,” said lead investigator Kevin McVary, MD, of Northwestern University Feinberg School of Medicine, Chicago.

“It is important, because it links the 2 diseases biologically. If you can affect a man’s erectile dysfunction simultaneously while trying to impact his lower urinary tract symptoms with 1 pill, it is very intriguing and exciting.”

In this 12-week, double-blind, placebo-controlled study, 366 men who scored ?25 on the erectile function domain of the International Index of Erectile Function, had an IPSS of ?12, and a prostate-specific antigen score.

April 28, 2003 -- A new study has found that the impotence drug Viagra could ramp up the sex lives of women who take it, just as it has done for men.

The 12-week study focused on 202 post-menopausal or post-hysterectomy women who complained of female sexual arousal disorder. The women in the group who took Sildenafil — the little blue pill commonly known as Viagra — took notes after each sexual experience, and reported better overall sexual satisfaction compared with those who took a placebo.

Their enhanced sex lives included better arousal, lubrication and orgasm. The study was conducted by Laura Berman, director of the Berman Center and a professor of OB-GYN and psychiatry at Northwestern cialis en linea University in Chicago, and Dr.

Jennifer Berman, director of the Female Sexual Medicine Center at UCLA Medical Center in Los Angeles.

The researchers say that the results are preliminary.

"In terms of ability to achieve orgasm, there was a statistically significant movement," Laura Berman said on ABCNEWS' Good Morning America. "It increases blood flow to the genital area, increases the sensation of warmth, tingling and fullness," she said. More than 50 million women experience some type of sexual dysfunction. Jennifer Berman said it's important for women to remember that this pill can't overcome mental and emotional barriers to a satisfying sex life.

"At this point, we can say that women with significant emotional or relationship problems and women that have desire problems related to their interest in being sexual might not be the best candidates," Jennifer Berman said. "It's for women who were satisfied with their sexual response at one point and now, for whatever medical reason, are no longer able to respond," she said.

Women who suffer from female sexual arousal disorder can experience a variety of symptoms, including lack of "excitement," vaginal dryness, loss of sensation and sensitivity in the genitals and nipples and low blood flow to the genitals.

Women in the study were screened to make sure that psychological or relationship issues were not the cause of the problem.

Since Viagra enhances sexual arousal in men by increasing the blood flow to the penis, the Bermans theorized that the drug could have a similar effect on women, increasing the blood flow to the female genitals and thereby producing better arousal, sensation and lubrication in the genital area. Women in the study were given doses of 50 milligrams, which was increased to 100 milligrams only once during the study based on how well the lower dose was working, and the women's tolerance to it.

The pill was to be taken prior to sexual activity but no more than once daily.

Each patient had to engage in sexual activity at least once a week and keep a personal log about it.

During the course of the study, neither the patients nor the doctors knew which patients were receiving the Viagra. Women taking Viagra reported mild to moderate side effects, including headache, flushing, nausea, and vision symptoms — the same side effects reported by men who take the drug. As drug development costs continue to rise and the level of attrition for new drug candidates remains intimidating, the search for new therapeutic agents within oncology has become increasingly challenging. Researchers both within and outside of the pharmaceutical industry will occasionally look at certain non-chemotherapeutic medications that have been in the market for a substantial amount of time for “off-label” indications within oncology. It is more typical for researchers to examine generic medications (as opposed to those still on-patent) based on the idea that there may be fewer potential legal blockades with generic therapies.

This type of strategy is sometimes called “repurposing” a medication. These medications typically have years of safety and efficacy data that helps reduce some of the financial burden associated with developing a new drug. One such medication that may have a role within oncology is the popular erectile dysfunction drug sildenafil.

Sildenafil works as a phosphodiesterase (PDE)-5 inhibitor, which increases levels of nitric oxide using cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP).

1 There is some preclinical evidence to support its antineoplastic properties, both in vitro and in vivo, with most of the data occurring within animal models.

2 There are several mechanisms by which PDE5 inhibitors could express antineoplastic effects.

PDE-5 inhibition has been shown to upregulate apoptosis in several different cell lines.

2,3 The apoptotic effect has been demonstrated within multiple cancers including prostate cancer, colorectal cancer (CRC), chronic lymphocytic leukemia (CLL), breast cancer, multiple myeloma, and melanoma.

In addition to apoptosis, PDE5 inhibition has also been associated with enhanced T-cell response against tumors and anti-inflammatory properties.

Recently, a study evaluated the effect of sildenafil and linaclotide (a guanylyl-cyclase C agonist) on intestinal tumorigenesis in mice.

4 When compared with water controls, the study found a significant reduction in the number of polyps per mouse by 50% and 67%, respectively ( P 5 Sildenafil was shown to lower serum immunoglobulin M (IgM) levels and induce apoptosis of certain B cells in these patients.

A larger, follow-up study to this found that 63% (19/30) patients treated with sildenafil had lower serum IgM levels and lack of disease progression.

Sildenafil Use and the Risk of Melanoma Do Clinical Trials Overstate New Cancer Drugs' Survival Benefits?

ASTRO: Daily Sildenafil During RT Improves Sexual Function in Patients with Prostate Cancer. In addition to antineoplastic data, there have also been limited reports of a link between PDE5 inhibitors and an increased risk of certain types of cancer. An increased risk of melanoma (HR = 1.92, 95% CI 1.14-3.22) was reported in a large prospective cohort study conducted by Li and colleagues.

7 This increased risk was not seen in basal or

squamous

It was postulated that reduced expression of PDE5A could lead to increased invasiveness of melanoma cells.

7,8 Subsequent studies have showed lower hazard ratios and lack of dose response.

2 Therefore, much of the current opinion is that there is lack of evidence to support causality. In addition, there was initially some concern regarding biochemical recurrence of prostate cancer after radical prostatectomy and long-term PDE5 inhibitor use, however, more recent studies have actually shown a potential protective effect.

Viagra is the brand name for a medicine known as Sildenafil which has been proven to be effective for the treatment of erectile dysfunction. Sildenafil is the active ingredient and has also been available since 2013 as a generic drug. A generic drug contains the same active ingredient as a branded drug and is medically equivalent but can be produced by any generic manufacturer. History – Pfizer Loses Patent in 2013 on Viagra Allowing Generic Viagra (Sildenafil) Viagra was one of the first treatments to be approved for the treatment of erectile dysfunction and has been used by men across the world for over a decade with excellent results. Pfizer was the original manufacturer for Viagra and developed a patent on the product in 1996. Originally Viagra was used for the treatment of heart disease, but during clinical trials it was noticed that it also helped treat erectile dysfunction.

In 1998, Pfizer received FDA approval to license the product for the treatment of erectile dysfunction.

In 2013, the Pfizer patent on Viagra ended in the EU, allowing generic manufacturers to start producing their own version. The generic version of the drug is known as Sildenafil which is the active ingredient in Viagra. The name Viagra is still a brand name which only Pfizer can use. So effectively in the market the drug can be bought as either the branded Pfizer product Viagra, or the generic drug Sildenafil.

Pfizer, as well as holding the rights to use the brand name Viagra, has a patent on the unique blue diamond appearance of Viagra. For many people, Viagra is known as “the little blue pill” and this is still associated with only the branded Pfizer product. The appearance of the product is purely cosmetic and has no medical difference. Sildenafil is a generic drug which means that its price is not controlled by a single manufacturer.

As several manufacturers produce Sildenafil, the market is very competitive which has helped drive down the price substantially.

Viagra on the other hand is produced only by Pfizer who control the price without any competition. As Viagra is a well known brand name, Pfizer are able to charge a premium price.

However, as Sildenafil becomes more well established it is expected that demand for the branded Viagra product will decrease and the price for Viagra will drop as a consequence.

Sildenafil 50mg Viagra 50mg 4 tablets ?19.99 ?34.99 8 tablets ?29.99 ?69.99 12 tablets ?39.99 ?104.99 16 tablets ?49.99 ?139.99 24 tablets ?69.99 ?189.99 28 tablets ?79.99 ?209.99 32 tablets ?89.99 ?239.99 64 tablets ?139.99 ?479.99.

Viagra has been proven to be a very effective treatment for erectile dysfunction with over 80 percent of men finding it works for them. Sildenafil is produced by several manufacturers and contains the exact same medical ingredient and dosage as the branded Viagra counterpart. To receive market approval, a generic medicine must be ‘bioequivalent’ to the branded product which ensures that the generic product has the same effectiveness.

As a result you can be confident that the Sildenafil sold in the UK is as effective as the branded Viagra tablets.

Sildenafil citrate (Viagra; Pfizer US Pharmaceutical Group, New York, NY) is prescribed for millions of men with erectile dysfunction. There are well-known risks of cardiovascular events in patients taking sildenafil concomitantly with organic nitrates.

1,2 ? However, little is known about stroke risk in patients with previous cerebrovascular events who take sildenafil. In both placebo-controlled and open-label studies, sildenafil was not associated with an increased risk of stroke. 2 These studies, however, excluded patients who had had myocardial infarction, life-threatening arrhythmia, or stroke in the previous 6 months 2 —a population at very high risk for subsequent stroke.

We describe a patient who suffered a TIA followed by a stroke in the same distribution 6 days later, and each event was associated with sildenafil use. A 50-year-old, right-handed man ingested 50 mg of sildenafil without achieving an erection or participating in sexual intercourse. Two hours after taking the medication he developed right facial weakness, slurred speech, difficulty swallowing, altered right hemibody sensation, … Sildenafil vs.
