To help clarify the effectiveness, side effects and cost of weight loss drugs now available, Metabolism.com is providing this breakdown for consumers.
According to the CDC, the prevalence of obesity in the USA is ever-increasing and reached an all-time high of 42.4% of adults over the age of 20 in 2017 to 2018.
Despite the prevalence of obesity in the USA, only around 3% of sufferers take medication. Low uptake of obesity medication is partly due to patchy insurance coverage, as about 1/3rd of insurers don’t cover obesity drugs at all, including Medicare and Medicaid in around half of all states. (more…)
As a culture we don’t plan for a sudden halt in scientific advancements. Our tendency is to expect progress to be rapid and continuous. My prediction is that in certain areas of medical science we are likely to see not only a halt in progress but a slipping backward. In particular, the realm of medical weight management is in complete disarray at this time. Two new drugs designed to induce weight loss have been shot down by the FDA in the last few months. The first is Qnexa, developed by Vivus Inc. Interestingly, Qnexa combines two drugs already approved for use in the U.S. One of the drugs is phentermine which is a medication used for decades as an appetite suppressant. The other is a common drug used to treat seizures with the brand name Topamax (topiramate) which also induces weight loss. The drug performed admirably in clinical trials with most participants losing over 10% of body mass. The FDA cited excessive risks of the drug in its statement of rejection. One wonders why the drugs are still being marketed separately if they are so dangerous.
The latest drug to be rejected by the FDA is Lorgess (lorcaserin), developed by Arena Pharmaceuticals. This drug, not as effective as Qnexa, produced 5% body mass loss in about half of participants in clinical trials. Lab animals showed a tendency to develop breast tumors when exposed to the medication, adding to the FDA’s decision to reject the drug application based on safety concerns.
I am a strong advocate of drug safety and regulation. On the other hand we know obesity, and with it Type 2 diabetes, is epidemic in the U.S. I regard weight loss as the “holy grail†when treating type 2 diabetes and yet it is the most difficult goal to achieve. Any drug which could assist in weight loss is highly desirable in the treatment of Type 2 diabetes. Not only does blood sugar improve with weight loss but also blood pressure and cholesterol readings show declines. All three of these parameters are known to be prime contributors to the main cause of death in diabetics, cardiovascular disease.
It has already been 10 years since the last drug was approved specifically for a weight loss indication. The failure of these two latest medications to achieve approval is certain to cause the pharmaceutical industry to severely curtail if not abandon further investment in this type of drug development.
Why is the FDA so reluctant to approve a weight loss pill? This is a complex issue but requires an answer. A new weight loss inducing medication is certain to be highly anticipated and widely prescribed. Therefore, from the very first day of approval the FDA must take responsibility for the well being of millions of people who are likely to take the medication. We are a society which demands our medications deliver miraculous cures with no side-effects. If someone perceives they have been injured by a medication our legal system is primed to unleash brutal retribution on everyone remotely involved in the approval process. Abuse and injury with a medication designed to cause weight loss is almost a certainty. This is a no-win situation for the administration of the FDA. I predict it will be at least another 10 years before a medication for weight loss is approved by the FDA. Unless there is a change in the climate of litigation in this country it will take longer than that. In the meantime the only new developments in weight loss drugs will be the result of exploiting appetite suppressant effects which are the “side-effect†of medications approved for other purposes.
The mission of the The Thyroid Project is to encourage sharing of information and experience between the public and the medical community about the treatment of hypothyroidism (low thyroid function). For at least the past few decades there is a growing awareness of “something missing†in the way suffers of hypothyroidism are treated for their disease.
Too many patients, as documented in an on-line study of 12,000 individuals conducted by the American Thyroid Association published in June 2018, (https://doi.org/10.1089/thy.2017.0681) , complain of persistent symptoms of hypothyroidism despite what their doctors believe is successful treatment with levothyroxine (brands include Synthroid, Unithroid, Tirosent, Levoxl). We believe something needs to be done to resolve this conflict between patients and their doctors.
By Gary M. Pepper, M.D. Ozempic, Rybelsus, Trulicity, Wegovy, Saxenda are the central players in the weight loss craze sweeping across the globe. Metabolisim.com has been monitoring this phenomenon from its beginnings in 2008 with its report “Lizard Spit Reduces Blood Sugar and Appetite”, regarding the first drug in this class, Byetta (exenatide). Caught In the middle of the current chaos are the medical experts who treat diabetes and have been prescribing these medications for more than a decade. Here is a brief commentary from one such board certified endocrinologist; “I started treating Type 2 diabetics with GLP-1 agonists more than 10 years ago. In some respects, these medications have revolutionized the treatment of diabetes by lowering blood sugar effectively and promoting weight loss at the same time, a unique combination of benefits. Not everyone benefits from these drugs to the same degree unfortunately, and I have seen lots of patients experience unacceptable side effects from them. Nothing though, has prepared me for what is happening now. Too often, I find myself confronting someone who expects me to prescribe one of these drugs just so they can lose weight. Sadly, one extreme example was someone who, despite battling a life threatening medical condition, was insistent on getting a prescription. At the same time my diabetic patients are scrambling to find a place to buy their medications if they can even afford it. It is disheartening, to say the least, and I dread the negative interactions with some of my patients I now face almost daily.”
Off- Label Use
The FDA is the U.S. government’s department tasked with evaluating and approving drugs for specific medical conditions. When a new medication is approved for treating a medical condition by the FDA the agency will, at the same time, set strict guidelines for exactly which patients may use the newly approved drug. When a medication is used “off-label” it means that these limitations are being overridden by the provider for a potential benefit which outweighs the drugs risks. It is a general misconception that off-label means illegal; it does not. This practice has been going on for ages and more than 20% of prescriptions in the United States are prescribed off-label. A common example is the use of beta-blockers (approved for heart problems) for the treatment of performance anxiety.
GLP-1 agonist drugs, as discussed recently by metabolism.com. were originally approved for the treatment of Type 2 diabetes in adults. In the past few years most of these same medications have gained unprecedented popularity for their “off-label” weight loss benefit. Of the 5 GLP-1 agents presently in U.S. pharmacies only Wegovy (semaglutide) and Saxenda (liraglutide) are FDA approved for treating obesity. Of these two, Wegovy is the newer and had been much more popular that its sister drug Saxenda, probably due to being dosed only once weekly compared to daily for Saxenda and less likely to cause side effects. Due to Wegovy’s soaring popularity, its manufacturer, Novo Nordisk, increased the price of Wegovy two times since its initial release.
by Gary M. Pepper, M.D. and Sam Jeans, MSc The global anti-obesity drug market, in 2021was valued at over $2 billion. Within one year this figure had skyrocketed to $8 billion and is expected to climb to nearly $ 20 billion by 2027. This astounding growth is a reflection of soaring obesity rates, and the arrival of a new class of weight loss medication fueling a craze both in the USA and across the world.
The FDA and global health regulators, until very recently, had maintained a very tight ship when it comes to treating obesity with medication, placing the emphasis on diet and exercise rather than weight loss drugs. Since the 80s, anti-obesity drugs continued to be controversial, and a more stringent FDA implemented ongoing safety trials along with other precautions. There is some speculation that a shift in attitude toward approval of weight loss medication by the FDA , is underway
Weight loss drug controversies are far from over and, in fact, may soon rival the amphetamine crisis of the 70’s. For that reason, metabolism.com has felt it important to provide our guide to weight loss drug issues, past and present.
Anti-Obesity Drugs Timeline
Prescription drugs for lifestyle diseases such as obesity were marketed heavily throughout the 1950s to the 1970s. Amphetamines entered the public domain after the Second World War where they were used extensively in the military.
In the 50s, walk-in clinics prescribed diet pills with other medications almost at random, with or without genuine concern for one’s weight. These brightly colored pills became known as “rainbow pills”.
In the 1960s and 1970s, the so-called “rainbow pill diet” of pills was finally coming to an end as the FDA began to systematically ban many of the drugs involved. A high-profile expose by investigative journalist Susanna Mcbee, published in Life magazine, brought attention to this new modern public health crisis.
The rainbow pill diet combined amphetamines, laxatives, thyroid hormones, and even diuretics to produce extreme weight loss, combined with benzodiazepines, barbiturates, and steroids to reduce side effects, and antidepressants to suppress medication-induced insomnia and anxiety.
In 1968, rainbow pills were linked to over 60 deaths, with numerous accounts of their devastating impact surfacing in the news and media. Within just two months, 48 million pills were seized and destroyed. Nevertheless, amphetamine-based diet pills remained extremely popular throughout the 1970s. In 1978, some 3.3 million prescriptions for amphetamines were written each year, with some 50 million pills a year ending up in the black market.
In 1979, the FDA banned amphetamines as a weight loss aid, but that is hardly the end of the USA’s love affair with obesity medication.
Here’s a brief timeline of recent anti-obesity drugs:
Lack of energy and inability to lose weight are constant challenges for many people and are every day complaints encountered in the doctor’s office. Almost anyone can find some relief from these problems by accessing the healing properties of physical activity. Mentioning to a patient the need for ‘more exercise’ often causes rolling of the eyes, sighing, shrugging, snorting or worse yet, the hundred-yard stare. We all know exercise is important but who has the energy for that? It seems like a vicious cycle. Surprisingly, when done correctly, exercise can improve energy with the additional advantage of promoting weight loss and restoring tone and stamina. It is helpful to remember that the human body was designed for a lot more physical activity and a lot less food than we are privileged to experience in present day life. It therefore takes will power and knowledge to maintain the environment required for optimal health. Here are eight steps to get in the swing of regular exercise. Some suggestions may surprise you.
