"So many women tell me they love their men but they would 'rather have a cup of tea'." In fact, low libido in women is a complex issue, with a wide range of potential causes. These can range from relationship problems to hormonal conditions, and should be addressed on a case-by-case basis. But to put it extremely simply, mental and physical arousal are

two

"Both men and women can be genitally aroused without any mental interest," says Patel. "It's a separate mechanism, which allows lubrication in

women

Many people experienced a drop in libido during lockdown and with restrictions still in place, m. What this means, then, is that a woman could take Viagra without seeing any real effect on her sexual functioning (depending on how this is defined).

All this said, there have been some studies in which female Viagra users have reported an increase in sexual pleasure.

The most famous of these, conducted by the UCLA Female Sexual Medical Center in 2003, involved 202 postmenopausal women with female sexual arousal disorder (FSAD). (Importantly, none of these women reported emotional difficulties or problems in their relationships.) Over the course of the 12-week trial, participants took either Viagra or a placebo prior to sexual

activity

However, follow-up studies have failed to replicate these

results

On a similar note, we can't say definitively how safe the drug is for women.

While it has been well tolerated in studies, there isn't much information out there about its long-term effects. What we do know for sure is that you shouldn't mix it with certain other drugs.

"It's generally a very safe drug, but if you're opening up blood vessels, that means your blood pressure drops," says Patel. "If you're taking certain other medications that could make your blood pressure drop even further, it could be risky as you could pass out or reduce the blood flow to your heart or brain." Viagra can be particularly dangerous if combined with poppers (amyl nitrate), another drug often used recreationally to enhance sexual sensation. In rare cases, combining these two drugs has proven fatal. The quest for a 'female Viagra' So for women experiencing arousal problems, are there any other drugs that might help where Viagra can't? The answer to this, says Morton, will depend on the nature of the problem.

"The most important thing to address is: 'Does it hurt?' There are many gynaecological conditions to consider so get expert advice," she says. “The majority of postmenopausal women should almost certainly be using oestrogen into the vagina plus good lubrication if they're experiencing vaginal dryness or painful sex." Research suggests that topical oestrogen is generally pretty safe, at least in the short term, but some doctors may be cautious about prescribing such a medication if a woman has a history of oestrogen-positive breast cancer.

In these cases, there are many hormone-free vaginal moisturisers and lubricants available that may provide relief.

Patel adds that some postmenopausal women may benefit from small amounts of testosterone in addition to hormone replacement therapy (HRT).

While this is not generally recommended, owing to limited evidence about its efficacy and concerns about side-effects, he says some doctors will prescribe it 'off licence'.

Another interesting candidate is Addyi (flibanserin), a medication licensed in the US but not the UK. Intended for women with hypoactive sexual desire disorder (HSDD), it is thought to work on certain chemicals in the brain (serotonin, dopamine and norepinephrine) to increase sexual motivation. This drug was widely dubbed 'female Viagra' when it hit the market in 2015. However, it was something of a commercial flop, with critics pointing to its frequent side-effects and underwhelming impact. There is still some controversy as to whether it should be available or not.

"In studies, the drug was found to increase the number of sexual events that would occur by one per month," says Patel. "Lots of people said this is rubbish - if it only increases sexual events by one per month, what's the point in taking it? But for some women with very severe HSDD, one per month could be the difference between never having sex and having a sexual relationship with their partner." To date, then, we don't have a true 'female Viagra' - or even a real definition of what this would mean. If you're experiencing arousal difficulties, it is worth seeing your GP as a starting point, and perhaps a psychosexual specialist further down the line.

There are various treatments that might

However, the answer probably doesn't lie in a little blue pill from Boots. Sildenafil (Revatio ® ) Treatments for Pulmonary Hypertension.

Information is based on the United States Food and Drug Administration drug labeling.

Sildenafil is an oral medication called a phosphodiesterase-5 (PDE5) inhibitor approved for the treatment of pulmonary arterial hypertension (PAH) in World Health Organization (WHO) Group 1 patients.

The goal of this therapy is to improve exercise ability and delay clinical worsening.

Research studies showing the effectiveness of the medication included mostly patients with symptoms that were rated as WHO Functional Class II-III.Sildenafil is marketed as Revatio® for PAH and was approved by the United States Food and Drug Administration (FDA) in 2005.

Sildenafil is also marketed as Viagra® which is FDA-approved for the treatment of erectile dysfunction but not for the treatment of PAH.

PDE5 is a substance produced in the lungs and other parts of the body that breaks down another substance called cyclic guanosine monophosphate (GMP).

Cyclic GMP causes the blood vessels (arteries) to relax and widen.

Sildenafil decreases the activity of PDE5, so that more cyclic GMP is available for the blood vessels inside the lungs. This leads to relaxation, or widening, of those vessels. Relaxing and widening of the blood vessels in the lungs decreases the pulmonary blood pressure to

the

This reduces blood pressure in the lungs which generally results in the ability to be more active.

Revatio® is only available as a round, white 20 mg pill, to distinguish it from Viagra®, which is a blue diamond-shaped pill. Revatio® injection is supplied as a single-use vial containing 10 mg (12.5 mL) of sildenafil.

Sildenafil must be prescribed by a physician, and insurance approval must be obtained prior to starting therapy.

It is carried by most retail and specialty pharmacies, including Accredo Health Inc., Aetna Specialty Pharmacy, CVS Caremark, Cigna Tel-Drug, CuraScript, Kaiser Permanente Specialty Pharmacy, Precision Rx, Walgreens Specialty Pharmacy (Medmark) and WellCare.

It is expected that most health insurance plans will pay part of the cost of this medication.

However, some plans still

Depending on your insurance type, you may be eligible for assistance from the company that manufactures your therapy or from a non-profit charitable assistance organization.

The most frequent side effects are: Nose bleeds Headache Upset stomach and heartburn Flushing of the skin Difficulty sleeping Worsening shortness of breath Nasal congestion. Other side effects include: Fluid retention Nausea and diarrhea Pain in the extremity (arm or leg) Temporary muscle aches Fever Numbness.

A reduction in blood pressure throughout the body may occur because sildenafil relaxes blood vessels (arteries) throughout the body. Caution must be used in patients with low blood pressure, less than 90/50 mmHg for example. Caution is also needed in patients with dehydration, left-sided heart diseases and certain abnormalities of the body’s nervous system function.

Taking certain medications such as nitrates, nitric oxide donors or alpha blockers along with sildenafil can cause a significant drop in blood pressure. This could result in loss of consciousness or even death. You should make certain that you are not taking these medications before starting sildenafil. Use of sildenafil with medications known as nitrates is CONTRAINDICATED. Prolonged erection (greater than four hours) in a male patient is a rare but very serious side effect; if this should happen to you, you should go to an emergency room or contact your doctor immediately. Sudden loss of vision in one or both eyes has occurred in patients on PDE5 inhibitors.

The safety and effectiveness of sildenafil in pediatric PAH patients has not been established. Sildenafil does not exhibit harm to the fetus in animal studies; however it has not been evaluated in pregnant women or women

Mild-to-moderate liver disease does not require a dose adjustment.

No dose adjustment is required in patients with kidney disease.

Sildenafil may be associated with a serious condition known as vaso-occlusive crisis in patients with PH and sickle cell disease.

The effectiveness of sildenafil in PH secondary to sickle cell anemia has not been established.

Sildenafil is not recommended in patients with either of two rare diseases often associated with PAH: pulmonary veno-occlusive disease and pulmonary capillary hemangiomatosis. What are important drug interactions with sildenafil? (Please see package insert for full details) Sildenafil should not be used in combination with nitrates or nitric oxide donors as an unsafe drop in systemic blood pressure may occur.

Caution should be used if sildenafil is to be used in combination with either alcohol or anti-hypertension or blood-pressure-lowering medications.

Sildenafil is broken down predominantly by an enzyme called CYP3A in the liver; therefore, order sildenafil citrate important interactions may occur with medications that affect this enzyme pathway.

Simultaneous use of bosentan and sildenafil may result in increased bosentan blood levels and decreased sildenafil blood levels.

It is not known if these changes are clinically significant. Although a drug interaction has been demonstrated with sildenafil and bosentan, dose adjustments are presently not recommended for either drug. Patients with human immunodeficiency virus (HIV or AIDS) who are taking medicines called antiretroviral agents should not use a phosphodiesterase inhibitor such as sildenafil since it can dramatically impair the efficacy of the antiretroviral.

Use of sildenafil with epoprostenol may reduce the blood level of sildenafil.

Use of sildenafil with beta blockers (another type of heart or blood pressure medicine) may increase the levels of sildenafil. Miscellaneous considerations: Is there any risk of blindness when using sildenafil?

There have been rare reports of blindness with use of all the currently available PDE5 inhibitors, including sildenafil.

This type of blindness, which may be permanent, is called non-arteritic anterior ischemic optic neuropathy (NAION). It is not yet clear whether this is related to the use of sildenafil or to the underlying cardiovascular diseases that place the persons at risk for this particular type of blindness, even in the absence of sildenafil use. There is no research to determine whether use of sildenafil is beneficial or safe in patients with retinitis pigmentosa, and use in these patients is not recommended.

As noted above, patients taking sildenafil should seek immediate medical attention in the event of sudden vision loss.

Yes, studies have evaluated sildenafil in both men and women with PAH, and no differences in side effects have been reported between genders.

Studies have not shown any effect on sexual function in women who have taken sildenafil. Older men like Playboy’s Hugh Hefner and actor Michael Douglas have sung the praises of Viagra, but now scientists say the erectile dysfunction pill is not only good for your sex life — it’s good for your heart.

In the bedroom, Viagra allows greater blood flow to the penis. But in the heart, the “little blue pill” can prevent heart muscle thickening and early-stage heart failure, according to research published today in the open access journal BMC Medicine. "Large clinical trials are now urgently needed to build on these buy sildenafil usa encouraging findings,” said lead author Dr. Isidori, associate professor of endocrinology at Sapienza University of Rome.

Dosages used for heart ailments are lower than those used for erectile dysfunction, and patients in the study showed few side effects. “Surprisingly, in over 1600 treated subjects, no increased risk of visual disturbance, photosensitivity and ‘blue haze,’ was observed,” he told NBC News. The active ingredient in Viagra is sildenafil citrate, which is a phosphodiesterase type 5 inhibitor (PDE5i).

The inhibitor blocks

the

Researchers analyzed randomized trials that had been published between January 2004 and May 2014, choosing 24 involving mixed populations of patients who were treated with PDE5i or a placebo.

PDE5i was given to men who had cardiovascular disorders, but who did not necessarily suffer from sexual impotence, according to Isidori.

The study found that the inhibitor prevented the heart from changing shape in patients suffering from left ventricular hypertrophy, a condition that causes thickening and enlargement of the heart muscle.

The drug also improved functioning of the heart in patients with a variety of cardiac conditions, with no effect on blood pressure. In fact, researchers found that the drug improved efficiency when the heart pumped blood purchase sildenafil into vessels, along with relaxation between beats. “Very few drugs used in cardiology can actually affect these parameters. For this reason their implications in the treatment and prevention of heart failure are huge.” However, Isidori notes that because these studies were conducted exclusively on men, the next step should be a larger trial on women.

"A significant number of subjects suffering from erectile dysfunction are much happier to take pills for heart failure or high blood pressure than to improve their erections." “I am not surprised and it’s good news,” said Dr. Kloner, professor of medicine in the cardiovascular division at the Keck School of Medicine at USC in California.

“We can always use a new drug for heart failure." Kloner co-authored the book, “Viagra: How the Miracle Drug Happened & What It Can Do for You.” He said this is not the first time, scientists have looked to Viagra for potential heart benefits.

In 1989, British scientists tested sildenafil citrate as a medication to treat high blood pressure and angina.

By the 1990s in early trials of the drug, researchers price of sildenafil 100mg noticed an interesting side effect — an increase in erections. In 1996, the pharmaceutical company Pfizer patented it as Viagra, and in just two years, doctors had ordered more than 40,000 prescriptions of the new wonder drug.

“When the drug first came out there was a big scare — is this going to kill people?” said Dr. Kociol, director of the heart failure program at the CardioVascular Institute at Beth Israel Deaconess Medical Center in Boston. “But in all studies, to the best of my knowledge, it’s not shown any increase in cardiac events in patients who take these drugs,” he said.

Past studies have suggested Viagra and other PDE5 inhibitors may have benefits for heart failure by decreasing pulmonary artery resistance and providing cardio-protective effects in settings with low blood flow, according to Kociol.

“They also improve exercise tolerance in patients with heart failure,” he said.

The drug may even reduce the size of a heart attack.

But Kociol said scientists have to “temper” their enthusiasm as more studies are necessary.

“As interesting as this paper is, there have been conflicting results,” he said.

“If there is a silver bullet, it remains to be seen.” Kociol added that researchers also need to “pay more attention” differences between men and women and between racial groups.
