Sildenafil (Viagra®) Classification: Phosphodiesterase Inhibitor.

About: Sildenafil (Viagra®) Sildenafil is a medication that is taken before sexual activity and allows men with erectile dysfunction (ED) to achieve and maintain an erection.

ED or impotence is a condition in which a man is unable to achieve or maintain an erection long enough for sexual intercourse. This can be a result of medical conditions such as high blood pressure, diabetes, prostate problems, and heart disease, or a side effect of the medications typically taken for these conditions. Personal lifestyle factors such as stress, alcohol and/or tobacco use can also play a contributing role.

During surgery or radiation to the pelvic area (including prostate, bladder, and rectal procedures), damage can occur to the nerves that supply the penis.

This can result in either temporary or permanent impotence.

Some surgeons perform "nerve-sparing" surgeries in an attempt to preserve erectile function.

Even in these cases, however, the nerves will suffer some injury, and it can take 18-24 months or longer for erectile function to return. These men should be treated aggressively with oral or injectable medications for ED in order to speed recovery of the nerves and to prevent muscle wasting in the penis.

It should be taken around 60 minutes before sex, but can be taken as much as four hours or as few as 30 minutes before sex.

Your doctor will determine the dose that is best for you. Some men require dose adjustments to find the dose that works best for them.

Talk to your doctor, nurse or pharmacist if you have concerns about these side effects.

Do not take a higher dose of sildenafil than your provider orders for you. Headache, facial flushing, stuffy or runny nose, and upset stomach can occur. Less frequent side effects include blurry vision, a bluish hue to the field of vision, difficulty telling the difference between the colors blue and green, a sensitivity to light, or a sudden loss of vision or hearing.

If you experience any of the following while using sildenafil, you should seek immediate medical attention: An erection lasting more than 4 hours.

Chest, arm or neck pain, or nausea during sexual activity. Sudden loss of vision in one or both eyes, loss of hearing, ringing in the ears or dizziness.

Diabetic men with erectile dysfunction might consider a prescription for a drug like Viagra to be a permanent cure for a temporary issue: buy 10 viagra pills 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 [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.
