    A Woman’s Guide to Reviving Sex Drive

    erectile dysfunction drugs

    Has the “free love” generation lost its mojo?

    If you talk to baby boomer gals, it seems the answer is yes. Indeed, as
    millions of women enter sildenafil citrate india and then
    transgress to menopause and beyond,
    many say they check their sex drive at the door and most are not happy about
    it.

    “I don’t think a day goes by when at least one patient and usually
    more complain that their sex drive is dropping off and want to know what they
    can do about it,” says Laura Corio, MD, a gynecologist and clinical
    instructor at Mt. Sinai Medical Center in New York City.

    Clinically known as HSDD (hypoactive sexual desire disorder) Corio says she
    doesn’t think more women are affected now than in the past, but she does
    believe more are coming forward — prompted, at least in part, by the success
    male potency drugs like Viagra.

    “The man gets a prescription for Viagra and he’s ready to rock and roll
    while she’s thinking ‘Hey, where’s my pill?’ If she’s not ready to jump in the
    old van and join him for a ride, there can be real problems,” says
    Corio.

    What’s Wrong

    While male sex drive is easy to define — and relatively easy to restore –
    that’s often not the case for women. Because the female sex drive is
    ed tabs
    , the desire to make love is not only influenced by physical
    issues, but emotional ones as well.

    “Part of the desire to make love is clearly physical, but part is also
    emotional depression can make a
    difference, so can any emotional issue in a woman’s life; female sex drive is
    very multidimensional,” says Glenn D. Article drug dysfunction erectile from internal medicine news rx update, MD, an endocrinologist
    and chair of the department of medicine at Cedars Sinai Medical Center in Los
    Angeles.

    While emotions are frequently behind a loss of sex drive in younger women,
    doctors say it is frequently the agingprocess itself that’s at
    when desire changes in women over age 45.

    “The very fact that a woman is no longer ovulating regularly, or not
    ovulating at all, automatically takes her sex drive down a few notches,”
    says Steven Goldstein, MD, professor of ob-gyn and NYU Medical Center in New
    York City.

    Nature’s Design for Sex

    Indeed, as many women are aware, Mother Nature built in a natural increase
    in the desire for sex beginning just prior to ovulation, and lasting several
    days afterwards — not coincidentally, the only time of the month conception is
    possible.

    Stop ovulating, says Goldstein, and you automatically lose that regularly
    scheduled boost in your sex drive that has been present since puberty — and
    you’re probably going to notice.

    “There’s nothing wrong with you; it’s just the way nature works,”
    says Goldstein.

    Moreover, around menopause, when there
    is also less estrogen circulating in your body, that too can bring your sex
    drive down for the count.

    “Estrogen is a mood elevator, it works in the brain to maintain interest
    in sex, but it also works at the level of the genitals, helping to increase
    sensation and just making sex more herbal erectile dysfunction treatment,” says Corio.

    Without it, she says, not only can desire take a dive, vaginal tissue begins
    to dry and shrink. As a result, intercourse can become uncomfortable, or even
    painful. Problems with desire, say experts, are easy to understand.

    “Who wants to make love when making love hurts?” asks Goldstein.

    Moreover, he says, avoiding sex because of pain only leads to more pain. The
    old “use or lose it” theory really does apply.

    “From a strictly physical standpoint, the less sex you have the more
    painful it is when you try to have it,” he says.

    Clinical Trials About ED

    erectile dysfunction drugs

    There are currently several clinical trials under way for treating erectile
    dysfunction (ED) caused by prostate cancer.

    Trial 1

    In this trial, the brand generic online viagra
    of nerve-sparing prostatectomy (surgical
    removal of the entire prostate while preserving the erection-controlling
    nerves), with and without nerve grafting, followed by standard therapy is being
    examined. Participants will be in one of two groups: the first group will have
    nerve-sparing prostatectomy with nerve grafting, then will use a standard
    therapy such as Viagra, a vacuum ed tabs
    device, injection therapy, or
    MUSE (suppository in urethra for erections) therapy. Participants in the second
    group will have the nerve-sparing surgery without nerve grafting, and will use
    the same standard therapy as the first group. The objectives of the study are
    to compare the two types of surgery for effectiveness and their effects on
    potency rates and erection quality in men with prostate cancer.

    Trial 2

    This study will be evaluating the effectiveness of Prograf, a medication
    known to suppress the immune system, in the prevention of erectile dysfunction
    in men who have had a nerve-sparing prostatectomy. Participants will be in one
    of two groups: the first group will receive the active medication and the
    second group will be given a placebo (sugar pill). The study will look at the
    percentage of people who can achieve buy online prescription viagra
    erectile function.

    Trial 3

    In the third trial, researchers are examining the effectiveness of erectile
    dysfunction treatment with Viagra versus a placebo for men with prostate cancer
    who have undergone radiation therapy and total androgen drug sample search viagra
    . The
    studies are attempting to determine if there is a difference in overall sexual
    function and satisfaction between Viagra and placebo.

    Trial 4

    This study will be looking at the effects of radiation therapy, high energy
    X-rays to destroy cancer cells, on erectile dysfunction. It will investigate
    whether reducing the dose of radiation helps to prevent ED. Participants will
    be placed into one of two groups: the first one will receive the standard
    radiation therapy while the second one will receive a restricted dose of
    radiation.

    ED Drugs May Treat Urinary Problems

    erectile dysfunction

    May 22, 2007 — Medications commonly used to treat erection problems in men
    may also relieve the bothersome urinary symptoms associated with an enlarged
    prostate gland, researchers say.

    Studies on the topic were presented this week at the annual meeting of the
    American Urological Pills
    in Anaheim, Calif.

    “Before, we looked at these two conditions as two different
    diseases,” says Kevin McVary, MD, professor of urology at Dysfunction erectile pill

    University Feinberg School of Medicine in Chicago, who moderated a press
    briefing.

    But in the past three or four years, he says, the thinking among urologists
    has changed.

    Sexual performance in men seems to decline as their prostate enlargement
    becomes more severe, experts have begun to notice. Doctors also notice
    that men with milder prostate problems often have less erectile erectile dysfunction treatment

    (ED) than do those with moderate or severely enlarged prostates and urinary
    symptoms.

    “These two diseases — erectile dysfunction and the lower urinary tract
    symptoms associated with benign prostatic hyperplasia — are probably
    linked,” McVary says.

    Conditions Increase With Age

    Prostate problems and ED problems both tend to increase with age. About 31%
    of men aged 50 to 59 have an enlarged prostate (also known as benign prostatic
    hyperplasia or BPH); 44% of those 70 and older have an enlarged prostate,
    according to the National Institutes of Health. As the gland enlarges, it
    constricts the urine-carrying tube called the urethra, making it difficult to
    empty the bladder.

    Common symptoms of BPH include weak urine stream, leaking or dribbling,
    feeling that the bladder hasn’t emptied completely after voiding, and more
    frequent urination.

    Medications are prescribed to relieve the symptoms. Some medications work by
    relaxing the muscles at the neck of the bladder and prostate; others inhibit a
    hormone that contributes to the growth of the gland.

    Erectile dysfunction, defined as an inability to get or keep an erection, is
    experienced by 20% to 46% of men aged 40 to 69, according to the NIH.
    Medications to treat erection problems help increase blood flow to the penis
    when a man is sexually stimulated.

    Cialis Study

    A once-a-day dose of Cialis helped men with erectile dysfunction and
    moderate to severe urinary tract symptoms due to an enlarged prostate improve
    sexual functioning, says Marc Gittelman, MD, a urologist in Aventura, Fla., and
    a study researcher.

    Of the 281 men who enrolled in the study, “81% were sexually active, and
    they were in their low 60s,” he says. All had moderate to severely enlarged
    prostates and urinary problems; 68% of the sexually active men had a medical
    history of erectile dysfunction. Gittelman’s team assigned about half to take
    placebo and half to take Cialis.

    At the end of 12 weeks, men who took Cialis — first 5 milligrams a day and
    then up to 20 milligrams — had erectile pill
    higher scores on a standard index
    of erectile function, he says.

    He especially wanted to see if they were as likely to do well if their
    urinary problems were severe as opposed to moderate. “They are equally
    impotence viagra likely to respond to a dose of Cialis,” he says.

    The study was funded by Lilly, which is the maker of Cialis.

    In another study, 223 men aged 45 to 64 who had urinary symptoms due to an
    enlarged prostate were assigned either to a group given 10 milligrams of
    Levitra twice daily for eight weeks or a placebo for the same time period.

    Compared with placebo, treatment with the ED drug significantly improved the
    men’s quality-of- life scores and their reports of urinary obstruction and
    irritation, says Boris Schlenker, MD, a urologist at
    Ludwig-Maxmillians-Universitaet Hospital in Munich, Germany, who presented the
    data. Erectile function improved in those who took the ED drug.

    “Levitra is a promising new drug for men with lower urinary tract
    symptoms, but we need long-term data on how it might affect the progression of
    the disease,” he says.

    The Viagra Study

    In a third study, McVary assigned 369 men aged 45 and up who had both
    erectile dysfunction and lower urinary tract symptoms to take either 50
    milligrams of Viagra every night, 50 milligrams of Viagra an hour before
    planned sexual activity, or to take a placebo. The dose increased to 100
    milligrams after two weeks.

    When he evaluated their erectile function and urinary symptoms, he found 73%
    of the men with severe symptoms improved to having mild or moderate symptoms at
    the end of the study.

    “The changes in prostate symptom scores were dramatic,” he says.
    “They compete with alpha blockers.” Alpha blockers are one type of drug
    commonly prescribed to treat urinary symptoms associated with an enlarged
    prostate. The more severe the urinary symptoms, the greater the
    relief, he says.

    The study was funded by Pfizer, which is the maker of Viagra.

    “This really is cutting-edge,” says Gittelman.

    The experts aren’t sure if the ED drugs will eventually supplement or
    replace drugs used for urinary problems associated with an enlarged prostate,
    or if new formulations might be developed to deal with both conditions.

    Some men on the ED drugs did report side effects, says Schlenker, with the
    most common in his study being headache.

    It’s not known exactly why the ED drugs also help the urinary symptoms,
    McVary says. By increasing blood flow to the pelvic area, the ED drugs may help
    relax the bladder enough to relieve the urinary problems.

    Sexual Problems in Women - Medications

    erectile dysfunction

    sexual problems are often complex and interrelated.
    Medications may be used in treating certain conditions that contribute to
    sexual problems.

    Medication Choices

    Estrogen. If you only have vaginal
    dryness and irritation (and not other symptoms such as hot flashes), you can
    use a limited amount of
    estrogen in a cream, tablet, or ring in the vagina.
    The daily estrogen makes your tissue less thin and sensitive and more moist.
    Many women find that using a cream or tablet twice a week is enough. This may
    increase vaginal tone and lubrication, which will decrease
    vulvar dryness, irritation, and shrinkage (atrophy).

    If you also have other
    menopausal symptoms that affect physical and mental
    well-being, talk to your health professional about taking daily (systemic)
    estrogen therapy.
    Estrogen can increase the blood flow in the
    vagina, as well as reduce hot flashes and other
    symptoms of
    menopause.
    Estrogen therapy or
    estrogen-progestin therapy can be oral (pills),
    vaginal, or transdermal (with a patch). In a small number of women, hormone
    therapy causes heart disease, breast cancer, dangerous blood clots, stroke, and
    dementia. Talk to your health professional about whether this therapy is right
    for you.

    Testosterone. This hormone may play a part
    in a woman’s sex drive and satisfaction. The ovaries make
    testosterone throughout a woman’s lifetime. Women have
    the most testosterone in early adulthood; testosterone levels drop by half
    between the early 20s and the early 40s.

    In women who have their ovaries removed (oophorectomy),
    testosterone drops by 50%.10 If you have had an
    oophorectomy, your health professional may suggest trying
    testosterone therapy. But the U.S. Food and Drug
    Ed tabs
    (FDA) has not approved any testosterone therapy for women.

    What To Think About

    The card master sales viagra
    -estrogen formula called Estratest is
    not approved by the FDA. The company that makes it
    markets it for moderate to severe
    menopausal symptoms. It is also prescribed to some
    menopausal women to improve sexual desire and
    response. But Estratest is made with
    methyltestosterone, which the body uses differently than testosterone. It does
    not directly raise the amount of testosterone in your body. And, taking a
    testosterone by mouth does put you at risk for problems with your liver and
    possibly your heart. Using a patch or cream does not.

    At this time, there is no testosterone pill, patch, or cream
    approved for women-those made for men have too high a dose for women. Side
    effects of too much testosterone include acne, facial hair, and loss of hair
    and a deepening of the voice, which may be permanent.

    No studies have looked at the benefits and risks of taking
    testosterone for longer than 6 months. The long-term effects of testosterone
    therapy in women are not known.10

    Sildenafil (Viagra) is used to treat
    erectile dysfunction in men. The maker of this
    medicine has decided not to market it for improving women’s sexual desire and
    arousal. This was based on research showing that sildenafil was not effective
    for most women. The maker has commented that women’s sexuality is a complex mix
    of physical, emotional, and cure dysfunction erectile factors, and it is not as simple to
    treat with a medicine as male erectile dysfunction is.11

    Currently no medications are approved by the FDA to treat female
    sexual problems, although several paths are being studied, including
    stimulation of certain molecules (receptors) in the brain and increasing blood
    flow to the genitals. It is still too early in the process to know whether any
    of these medications will prove to be effective and safe treatment
    options.12

    Erection Problems (Erectile Dysfunction) - When To Call a Doctor

    erectile dysfunction

    erection problem (erectile dysfunction) and the

    Seek care immediately if you have taken
    erectile dysfunction advices
    5 inhibitors (such as Viagra,
    Levitra, or Cialis) in the past 24 hours and are having chest pain. Tell your
    health professional you are taking this medication. Do
    not
    use any form of pills
    if you have chest pain and have taken
    Viagra, Levitra, or Cialis in the past 24 hours.

    Call a health professional if erection problems occur with:

    • Any type of injury to the back, legs, buttocks,
      groin, penis, or testicles.
    • A loss of pubic or armpit hair and an
      enlargement of the breasts.

    Make an appointment to see a health professional within 1 to 2
    weeks if an erection problem occurs more than 25% of the time and the
    problem:

    • Occurs with a persistent
      backache.
    • Occurs after you start taking a new medication or change
      the dose of a medication.
    • Is affecting your self-image or sense of
      well-being.
    • Has not improved despite self-care.

    If your erection problem is occasional, there is no reason to call
    your health professional. If it occurs frequently but does not bother you or
    your partner, you may or may not choose to call your doctor. However, an
    erection problem that develops suddenly may be a sign of a disease; it is
    recommended that you see your doctor.

    Watchful Waiting

    Watchful waiting is a period of time during which you and your
    health professional observe your symptoms or condition without using medical
    treatment. A single episode of an erection problem is often a temporary and
    easily reversible problem. Do not assume it will happen again. If possible,
    forget about it and expect a more successful experience the next time. If you
    or your partner is concerned about it, talk about the problem and openly
    discuss your fears and anxieties.

    If self-care has not helped after 2 weeks and you are concerned
    about your inability to have an erection, see a health professional who has
    experience in dealing with erection problems.

    Who To See

    Some health erectile dysfunction drugs

    erection problems:

    • Family medicine
      doctor
    • Internist
    • Nurse
      practitioner
    • Physician assistant
    • Urologist

    If it is possible that a psychological problem is contributing to
    your erection problem, your doctor may refer you to a health professional such
    as a:

    • Psychiatrist.
    • Psychologist.
    • Certified licensed social
      worker.
    • Counselor with special training in sexuality or

    Drug May Ease Pulmonary Hypertension

    erectile dysfunction

    Nov. 16, 2005 — A drug called Revatio may help treat an aggressive condition called pulmonary arterial hypertension.

    Patients with pulmonary hypertension have elevated blood pressure in the pulmonary (lung) blood vessels. The condition often arises from lung problems, but some cases are without a known cause. It can result in heart failure and early death.

    Unfortunately, most of the lowest cost generic viagra
    that are used to treat this serious condition are not easy to take and are given by IV, injection, or inhalation — with real risks of unwanted side effects.

    Revatio has the same active ingredient — sildenafil — as Viagra. Revatio and Viagra are made by Pfizer.

    Pfizer funded the new study, which appears in The New England Journal of Medicine. Pfizer is a WebMD sponsor.

    The blindness causing citrate sildenafil included Nazzarene Galie, MD, of the cardiology institute at Italy’s University of Bologna.

    Walking Test

    The study lasted for 12 weeks. It included 278 patients with pulmonary hypertension. The patients lived in the U.S., Mexico, South America, Europe, Asia, Australia, South Africa, and Israel.

    Three times daily, the patients took Revatio (20, 40, or 80 milligrams) or an empty drug (placebo) orally. That was in addition to any other standard pulmonary hypertension medications.

    The big question was how far patients could walk in six minutes. That’s an important exercise test for patients with pulmonary hypertension. The farther patients can walk, the better.

    Walking Farther

    All of the patients taking Revatio walked farther at the end of the study:

    • 20Erectile dysfunction tablets
      group: Walked about 148 extra feet (a 13% increase).
    • 40-milligram group: Walked about 151 extra feet (a 13% increase).
    • 80-milligram group: Walked about 164 extra feet (nearly a 15% increase).

    Higher doses didn’t bring a notable increase in distance walked, the researchers report.

    Patients were then allowed to take Revatio for up to a year; 230 did so. The researchers looked at the walking tests of 222 of those who were only taking Revatio as treatment. After a year, they walked about 167 extra feet, on average, compared with the beginning of the study.

    How Patients Fared

    Most of the patients included in the study had milder stages of pulmonary hypertension. Few cases worsened, regardless of treatment type, the study shows.

    Patients taking Revatio weren’t any more or less likely to have their symptoms worsen during the trial.

    The study wasn’t designed to see if Revatio helped patients live longer. Four died during the study. No deaths were judged to be linked to the treatments, write the researchers.

    Side effects seen with Revatio were mild or moderate and included headache, flushing, muscle pain, and diarrhea, report Galie and colleagues.

    Heart Drug for Female Sexual Disorder?

    erectile dysfunction

    July 24, 2006 — Like Viagra before it, a drug once studied to treat heart problems may help treat sexual dysfunction. But this time it’s being tested exclusively for women.

    A new study shows that a modified version of the experimental heart drug Candoxatril was effective at dysfunction erectile pill
    blood flow to the vagina in animal tests.

    If further research confirms these results in humans, the drug may be used to treat female sexual arousal disorder (FSAD).

    Tadalafil vivanza sildenafil citrate vs
    say an estimated 40% of women suffer from FSAD or other forms of sexual dysfuction, such as low libido or pain during erectile dysfunction meds
    .

    Candoxatril went into clinical trials in the 1990s as a heart failureheart failure medication but has since become the focus of efforts to develop a medication to treat female sexual arousal disorder.

    How the Drug Works

    Candoxatril is one of several compounds that targets levels of vasoactive intestinal peptide (VIP), which controls blood flow to the vagina. Researchers say decreased blood flow to the vagina is thought to be a key factor in female sexual arousal disorder.

    An enzyme called NEP degrades VIP in the body, and Candoxatril works by blocking NEP.

    In a new study, published in the Journal of Medicinal Chemistry, researchers altered the molecular structure of Candoxatril in order to focus the drug to treat female sexual arousal dysfunction.

    In animal tests, researchers at Pfizer Global Research and Development in the U.K., found the new compound effectively blocked NEP, took effect quickly, and the effect lasted for a relatively short time.

    They say the results suggest that the drug might have similar effects in humans, but further research is needed.

    Viagra May Treat Other Ailments

    erectile dysfunction

    Nov. 7, 2005 - The drug made famous for its treatment of erectile dysfunction appears to have another erectile dysfunction help use.

    A study in the journal Drug side effects viagra
    suggests Viagra could help treat a circulatory disorder called Raynaud’s phenomenon, which affects about 5% of the population. Raynaud’s phenomenon can be associated with other diseases such as lupus.

    Raynaud’s phenomenon causes episodes of numbness, tingling, and pain in the fingers and toes, as well as skin sores or gangrene in severe cases. The attacks are spawned by spasms in small blood vessels in response to cold temperatures or emotional stress.

    These spasms cause blood vessels to constrict and compromise blood flow to distal areas such as toes and fingers. The disorder is sometimes treated with medications to relax the blood vessels, but this is not always successful.

    The Viagra study involved 18 patients (mostly women) whose Raynaud’s symptoms were not responsive to conventional therapies. While taking Viagra twice a day for four weeks, the patients experienced improved blood flow in the cialis generic levitra viagra
    and fewer Raynaud’s attacks. Symptoms improved and the duration of attacks was also shorter. In those who had skin sores, the ulcers began to heal visibly.

    These effects did not occur while patients were taking a placebo. At the end of the study, 16 of the participants asked to continue taking Viagra off-label (that is, for a purpose other than its FDA-approved use).

    Viagra causes blood vessels to dilate in a different way from other erectile dysfunction
    drugs, which may explain why it helped Raynaud’s patients who didn’t respond to standard treatments. The researchers conclude that drugs like Viagra could offer “a promising new approach in patients with microcirculatory disorders.”

    Although Viagra has risk for serious side effects such as heart attack, stroke, and vision loss, none of the study participants reported any such adverse effect. The side effects reported by study participants included headache, muscle pain, flushing, mild nausea, dizziness, and nasal congestion.

    One of the researchers has served as a consultant and speaker for Viagra’s manufacturer, Pfizer. Pfizer is a WebMD sponsor.

    Viagra May Help Crohn’s Disease

    erectile dysfunction

    Feb. 23, 2006 — Researchers in the U.K. have a new theory to explain the cause of Crohn’s disease, and they say medications like the erectile dysfunction drug Viagra may prove useful for treating the bowel disorder if they are right.

    In Crohn’s disease, chronic ed meds
    causes ulcers within the digestive tract that can lead to severe gastrointestinal symptoms, including abdominal pain, persistent diarrhea, and rectal bleeding.

    The most widely accepted theory is that an overactive immune system causes the damaging inflammation. But researchers from the University College London say the opposite appears to be true.

    They believe a generic omnigen viagra
    immune response triggers the bowel inflammation that leads to Crohn’s disease. Their research appears in the Feb. 25 issue of The Lancet.

    1 Disease, 2 Theories

    The prevailing theory of Crohn’s disease is that the body’s immune system reacts abnormally in people with the disorder, producing chronic inflammation that leads to bowel injury.

    Tony Segal, professor of medicine at University College London, explains the weak immune system theory like this: “The wall of the bowel is normally an effective barrier against the bowel contents, but sometimes the barrier is broken by an infection or injury and the bowel contents, which include large numbers of bacteria, penetrate into the bowel wall.

    “Normally, an acute inflammatory response would kick in to remove the bacteria and return the condition of the bowel to normal. But in Crohn’s disease, we think that the acute inflammation fails to kick-start, leaving bacteria to fester in the bowel wall which, in turn, triggers chronic, secondary inflammations.”

    Segal and colleagues conducted a series of small experiments that measured white blood cell production in response to intestinal and skin trauma in both Crohn’s patients and healthy patients. With inflammation, white blood cell numbers are expected to rise. In one experiment, researchers injected a killed gut bacteria into the forearms of patients and healthy get viagra prescription
    to study blood flow and immune response.

    They found that the Crohn’s patients produced unexpectedly lower levels of white blood cells and proteins involved in inflammation, compared with people without the disorder.

    Segal tells WebMD that people who carry a gene that has been linked to Crohn’s disease may be especially vulnerable to getting the disease if they have weak immune systems.

    He added that drugs like Viagra, which open the blood vessels and increase blood flow, may help.

    The Viagra Response

    The researchers tested this theory by treating 10 Crohn’s patients with 50 milligrams of Viagra after injecting them with the killed gut bacteria. They found that blood flow to the infected area improved.

    “Increasing blood flow is an important part of the inflammatory response, and that is why this drug may work,” Segal says. “But we don’t yet know if this will give rise to successful treatment. We need to study this further to find out.”

    Segal and colleagues are among a growing number of researchers suggesting that a weak immune system, rather than an overactive one, is largely responsible for Crohn’s disease, says University of Chicago associate professor of medicine Sunanda Kane, MD.

    She adds that the new research adds credibility to the theory but does not prove it.

    “This is a little more evidence that maybe we have been barking up the wrong tree,” she tells WebMD. “The idea that we should be strengthening the immune system — rather than erectile dysfunction treatment
    it — sounded a little crazy at first, but the evidence continues to come in. But we still have a long way to go to really understand what causes Crohn’s.”

    Biologic agents that stimulate a specific part of the immune system are now being tested in Crohn’s patients. If such treatments prove effective, Kane says doctors would have an effective alternative to steroids, which work well for many patients but have many side effects.

    “For decades now suppressing the immune system with steroids has worked, and we will continue to do so until we find dysfunction pills
    that work for everybody and are risk-free,” she says.

    Viagra: Treatment for Lung Disease?

    erectile dysfunction

    Oct. 25, 2006 — Viagra may ease blood pressure in the lungs of people with chronic lowest prices cheap generic viagra
    pulmonary disease (COPD).

    That’s according to a small Dutch study presented in Salt Lake City at Chest 2006, held by the American College of Chest Physicians.

    COPD is the No. 4 cause of death in the U.S. and worldwide, according to the National Heart, Lung, and Blood Institute (NHLBI).

    COPD is a lung disease in which breathing is difficult. It’s usually caused by smoking from generic india viagra
    , but it can also be caused by other lung irritants.

    The disease develops slowly and may take years to show symptoms, which include:

    • Cough
    • Sputum (mucus) production
    • Shortness of breath (especially with exercise)
    • WheezingWheezing
    • Chest tightness

    Those symptoms may or may not indicate COPD, states the NHLBI’s web site.

    Viagra Study

    The Viagra study included 12 COPD patients, half of whom had high blood pressurehigh blood pressure in the pulmonary artery, which brings blood to the lungs. The board levitra link message optional order url
    of pulmonary hypertensionpulmonary hypertension is a complication of COPD, but not everyone with COPD will develop it.

    The erectile dysfunction meds
    included Sebastiaan Holverda, MSc, of Amsterdam’s University Medical Center.

    They tracked the patients’ pulmonary artery blood pressure before and after taking Viagra.

    Why Viagra? It relaxes (dilates) blood vessels, lowering blood pressure and helping blood to flow.

    First, the patients rested. Then they pedaled a stationary bike for three minutes at a mild pace.

    As expected, pulmonary artery blood pressure was higher during exercise, since the lungs were working harder.

    Next, the patients took a Viagra pill, waited 45 minutes, and repeated the rest and exercise tests.

    Their pulmonary artery blood pressure during exercise was lower after taking Viagra.

    “These data suggest that during daily activities some COPD patients may benefit” from drugs that dilate blood vessels, the researchers write.
