But secondary Raynaud's can complicate collagen-vascular diseases or certain other conditions. It's not common, but secondary Raynaud's can be very painful and difficult to treat. Many medications have cialis or viagra for women been used without consistent success. But a 2005 study of 16 patients with severe Raynaud's phenomenon that had not responded to other medications reported benefit from sildenafil in a dose of 50 mg twice a day. And a 2006 study of 40 Raynaud's patients reported similar benefits from vardenafil in a dose of 10 mg twice a day.
Viagra and foods
Sildenafil was discovered by scientists looking for a new medication to dilate coronary arteries. It does that, but because it widens healthy coronary arteries more than diseased vessels, it has not been successful in treating angina. But it may have other benefits for cardiac patients. In the first years of the Viagra era, research on sildenafil and the heart was devoted to making sure the drug was safe for the circulation. In most men with heart disease, it is.
Drug details
But several studies of patients with congestive heart failure also reported that the medication improves oxygen consumption, pulmonary artery pressure, and exercise capacity in these patients. Research shows that sildenafil helps the heart muscle relax properly, which could help patients with heart failure due to diastolic dysfunction. Another interesting property is sildenafil's ability to protect the heart from excessive stimulation by adrenaline. Clinical trials will be needed to see which patients might benefit. It's the most speculative use for sildenafil, and it's far from clinical application.

Report Problems to the Food and Drug Administration
Viagra® (sildenafil) is an oral medication taken as needed to treat erectile dysfunction. Viagra® (sildenafil citrate), a phosphodiesterase type 5 (PDE5) inhibitor, is an oral medication used to treat erectile dysfunction (ED) by increasing blood flow to the penis. It is taken only as needed, usually about an hour before sexual activity, though it can be effective if taken between 30 minutes to four hours prior. It is very important not to take Viagra more than once a day, as exceeding this frequency increases the risk of serious side effects, including vision loss and significant drops in blood pressure. Viagra (sildenafil citrate) is indicated to treat: The cost of Viagra® may vary depending on factors such as your insurance plan, the dosage, quantity, and where you buy it. Viagra and sildenafil are virtually the same.
2.1 Dosage Information
And the FDA has approved sildenafil (Revatio) in a dose of 20 mg three times a day for men and women with pulmonary hypertension. Clinical trials have demonstrated improved exercise tolerance with few side effects. Pulmonary hypertension is a feature of acute mountain sickness. High altitudes produce low blood-oxygen levels. In turn, low oxygen produces a narrowing of the pulmonary arteries.
What is sildenafil used for?
The heart must therefore work harder, reducing the capacity to exercise. To find out if it might improve exercise capacity in low oxygen conditions, scientists tested 14 healthy mountain climbers in a lab in Germany and again at a Mount Everest base camp. In the lab, the volunteers breathed 10% oxygen through a mask; on the mountain, they breathed natural air. Under both conditions, a 50-mg sildenafil tablet decreased pressures in the lungs' blood vessels and increased the maximum exercise capacity. It's a small study, and it's too soon to say if sildenafil will help prevent or treat acute mountain sickness.
Typical dosages
Still, a study of 29 climbers reported that tadalafil can also reduce pulmonary artery pressure at a high altitude. In affected individuals, exposure to the cold triggers spasm of the small arteries that supply blood to the fingers, toes, or both. Temporarily deprived of adequate blood flow, the involved digits become pale, cold, and very painful. It's a common condition, affecting up to 8% of men and 17% of women. In the vast majority, there are no underlying diseases (primary Raynaud's), and patients do well simply by minimizing their exposure to cold. Research shows both to be effective treatments for ED, but Viagra is more expensive and may look different in terms of its pills and packaging appearance. It’s possible to take Viagra daily, but it may not be right for everyone.
What are the generic options for erectile dysfunction (ED)?
Still, it's an interesting area of new research. A European study of 25 men who had erectile dysfunction but no other circulatory disorders found that blood vessels in the brain responded to stress better after a 50-mg dose of sildenafil. More interesting results were reported by scientists in Michigan, who produced ischemic strokes in rats by temporarily blocking blood vessels. During their recovery, the animals were divided into three groups. One received no treatment, another low-dose sildenafil, and the third high-dose sildenafil.

The animals who got sildenafil recovered better, with the highest doses producing the best results. The scientists concluded that the medication actually stimulated the growth of new nerve cells in the brain tissue next to the stroke damage. It's far too dapoxetine viagra early to know whether sildenafil may someday help people with strokes. If you get your information about sildenafil from Super Bowl commercials or e-mail spam, you might dismiss it as a lifestyle drug of little real medical importance. In fact, it's a serious prescription medication that has helped millions of men who are distressed by an entirely legitimate medical problem.
Is Viagra a blood thinner?
Because the drug acts on arteries beyond the penis, it can produce various side effects. That means it should only be prescribed by a personal physician who really knows you. And it also means that scientists are investigating uses for the drug in patients with an array of vascular disorders having nothing to do with sexual function. They have nearly identical effects on ED as well as similar side effects. Because they are newer drugs, scientists are just beginning to study them for problems that don't involve sexuality. You should never take more Viagra than has been prescribed by your healthcare provider.
