Diabetes Drugs: Metformin

Diabetes Drugs: Metformin

Editor’s Note: This is the second post in our miniseries about diabetes drugs. Tune in on August 21 for the next installment. Metformin (brand names Glucophage, Glucophage XR, Riomet, Fortamet, Glumetza) is a member of a class of medicines known as biguanides. This type of medicine was first introduced into clinical practice in the 1950’s with a drug called phenformin. Unfortunately, phenformin was found to be associated with lactic acidosis, a serious and often fatal condition, and was removed from the U.S. market in 1977. This situation most likely slowed the approval of metformin, which was not used in the U.S. until 1995. (By comparison, metformin has been used in Europe since the 1960’s.) The U.S. Food and Drug Administration (FDA) required large safety studies of metformin, the results of which demonstrated that the development of lactic acidosis as a result of metformin therapy is very rare. (A finding that has been confirmed in many other clinical trials to date.) Of note, the FDA officer involved in removing phenformin from the market recently wrote an article highlighting the safety of metformin. Metformin works primarily by decreasing the amount of glucose made by the liver. It does this by activating a protein known as AMP-activated protein kinase, or AMPK. This protein acts much like an “energy sensor,” setting off cellular activities that result in glucose storage, enhanced entry of glucose into cells, and decreased creation of fatty acids and cholesterol. A secondary effect of the enhanced entry of glucose into cells is improved glucose uptake and increased storage of glycogen (a form of glucose) by the muscles. Additionally, the decrease in fatty acid levels brought about by metformin may indirectly improve insulin resistance and beta cell func Continue reading >>

Study Compares Long-term Effectiveness Of Diabetes Drugs

Study Compares Long-term Effectiveness Of Diabetes Drugs

Study compares long-term effectiveness of diabetes drugs Researchers at Washington University School of Medicine in St. Louis are seeking volunteers for a study that compares the long-term benefits and risks of four widely used diabetes drugs. The drugs will be given in combination with metformin (Gulcophage), the most commonly prescribed medication for treating type 2 diabetes. Over a period of five years, the researchers will evaluate how the drugs affect blood-sugar levels, diabetes complications and quality of life, as well as the medications side effects. In addition to determining which medications control sugar most effectively over time, we will examine individual factors associated with better or worse response to different drugs, said Janet B. McGill, MD, professor of medicine and principal investigator at the Washington University study site. This is a long-term study that will provide targeted diabetes care at no cost to participants. Although short-term studies have shown that drugs to lower blood sugar can be effective when used with metformin, no long-term studies have been conducted to determine which combinations work best to keep diabetes under control. The nationwide study is called the Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness (GRADE) study. It is expected to involve 5,000 patients across the country and 300 locally who have been diagnosed with type 2 diabetes within the past 10 years. Type 2 diabetes progresses slowly, over a long period of time, said Barbara Linder, MD, PhD, the GRADE project officer at the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health (NIH). This study will help us understand how different combinations of medications affect the disease over Continue reading >>

Therapeutic Use Of Metformin In Prediabetes And Diabetes Prevention

Therapeutic Use Of Metformin In Prediabetes And Diabetes Prevention

Go to: Pathophysiology and Diagnosis of Prediabetes The defects in glucose metabolism that underlie type 2 diabetes begin many years before the diagnosis of diabetes is made [6, 7]. The development of insulin resistance, in which the action of insulin on glucose metabolism is blunted, occurs early in the pathogenesis of dysglycaemia. Increased secretion of insulin initially compensates for the presence of insulin resistance; however, a simultaneous and progressive loss of β-cell mass and β-cell function limits the ability of the pancreas to maintain euglycaemia by increasing insulin secretion [8]. The early manifestations of prediabetic dysglycaemia represent one or both of [9]: impaired glucose tolerance (IGT), in which postprandial glucose control is impaired but fasting plasma glucose (FPG) is normal; impaired fasting glucose (IFG), in which a chronic elevation of FPG occurs in the absence of a deterioration in postprandial glucose control. Table 1 shows the usually accepted diagnostic criteria for the diagnosis of prediabetes based on measurements of glycaemia [4, 8–10]. A simple blood test is sufficient to diagnose IFG, while a 75 g oral glucose tolerance test (OGTT) is required for the diagnosis of IGT. The originally used cutoff level for IFG (110 mg/dL [6.1 mmol/L]) was reduced to that shown in Table 1 (100 mg/dL [5.6 mmol/L]) by an Expert Committee of the American Diabetes Association in 2003, in order to equalise the prognostic impact of diagnosis of IFG or IGT, in terms of the future risk of diabetes in a subject with either condition [11]. It should be noted that the World Health Organization (WHO) diagnostic criteria for IFG retains the 110 mg/dL (6.1 mmol/L) cutoff value for diagnosing IFG [12]. Diagnostic criteria from the American Diabetes Associatio Continue reading >>

Metformin: An Old But Still The Best Treatment For Type 2 Diabetes

Metformin: An Old But Still The Best Treatment For Type 2 Diabetes

Abstract The management of T2DM requires aggressive treatment to achieve glycemic and cardiovascular risk factor goals. In this setting, metformin, an old and widely accepted first line agent, stands out not only for its antihyperglycemic properties but also for its effects beyond glycemic control such as improvements in endothelial dysfunction, hemostasis and oxidative stress, insulin resistance, lipid profiles, and fat redistribution. These properties may have contributed to the decrease of adverse cardiovascular outcomes otherwise not attributable to metformin’s mere antihyperglycemic effects. Several other classes of oral antidiabetic agents have been recently launched, introducing the need to evaluate the role of metformin as initial therapy and in combination with these newer drugs. There is increasing evidence from in vivo and in vitro studies supporting its anti-proliferative role in cancer and possibly a neuroprotective effect. Metformin’s negligible risk of hypoglycemia in monotherapy and few drug interactions of clinical relevance give this drug a high safety profile. The tolerability of metformin may be improved by using an appropiate dose titration, starting with low doses, so that side-effects can be minimized or by switching to an extended release form. We reviewed the role of metformin in the treatment of patients with type 2 diabetes and describe the additional benefits beyond its glycemic effect. We also discuss its potential role for a variety of insulin resistant and pre-diabetic states, obesity, metabolic abnormalities associated with HIV disease, gestational diabetes, cancer, and neuroprotection. Introduction The discovery of metformin began with the synthesis of galegine-like compounds derived from Gallega officinalis, a plant traditionally em Continue reading >>

Stopping Metformin: When Is It Ok?

Stopping Metformin: When Is It Ok?

The most common medication worldwide for treating diabetes is metformin (Glumetza, Riomet, Glucophage, Fortamet). It can help control high blood sugar in people with type 2 diabetes. It’s available in tablet form or a clear liquid you take by mouth before meals. Metformin doesn’t treat the underlying cause of diabetes. It treats the symptoms of diabetes by lowering blood sugar. It also increases the use of glucose in peripheral muscles and the liver. Metformin also helps with other things in addition to improving blood sugar. These include: lowering lipids, resulting in a decrease in blood triglyceride levels decreasing “bad” cholesterol, or low-density lipoprotein (LDL) increasing “good” cholesterol, or high-density lipoprotein (HDL) If you’re taking metformin for the treatment of type 2 diabetes, it may be possible to stop. Instead, you may be able to manage your condition by making certain lifestyle changes, like losing weight and getting more exercise. Read on to learn more about metformin and whether or not it’s possible to stop taking it. However, before you stop taking metformin consult your doctor to ensure this is the right step to take in managing your diabetes. Before you start taking metformin, your doctor will want to discuss your medical history. You won’t be able to take this medication if you have a history of any of the following: alcohol abuse liver disease kidney issues certain heart problems If you are currently taking metformin, you may have encountered some side effects. If you’ve just started treatment with this drug, it’s important to know some of the side effects you may encounter. Most common side effects The most common side effects are digestive issues and may include: diarrhea vomiting nausea heartburn abdominal cramps Continue reading >>

Metformin

Metformin, marketed under the trade name Glucophage among others, is the first-line medication for the treatment of type 2 diabetes,[4][5] particularly in people who are overweight.[6] It is also used in the treatment of polycystic ovary syndrome.[4] Limited evidence suggests metformin may prevent the cardiovascular disease and cancer complications of diabetes.[7][8] It is not associated with weight gain.[8] It is taken by mouth.[4] Metformin is generally well tolerated.[9] Common side effects include diarrhea, nausea and abdominal pain.[4] It has a low risk of causing low blood sugar.[4] High blood lactic acid level is a concern if the medication is prescribed inappropriately and in overly large doses.[10] It should not be used in those with significant liver disease or kidney problems.[4] While no clear harm comes from use during pregnancy, insulin is generally preferred for gestational diabetes.[4][11] Metformin is in the biguanide class.[4] It works by decreasing glucose production by the liver and increasing the insulin sensitivity of body tissues.[4] Metformin was discovered in 1922.[12] French physician Jean Sterne began study in humans in the 1950s.[12] It was introduced as a medication in France in 1957 and the United States in 1995.[4][13] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[14] Metformin is believed to be the most widely used medication for diabetes which is taken by mouth.[12] It is available as a generic medication.[4] The wholesale price in the developed world is between 0.21 and 5.55 USD per month as of 2014.[15] In the United States, it costs 5 to 25 USD per month.[4] Medical uses[edit] Metformin is primarily used for type 2 diabetes, but is increasingly be Continue reading >>

A New Dual Drug Pill Aims To Boost The Effectiveness Of Metformin

A New Dual Drug Pill Aims To Boost The Effectiveness Of Metformin

Joslin does not endorse specific products or companies. This post is meant to be informational only. This October the FDA approved a new two-in-one pill to treat type 2 diabetes. The drug, marketed as Xigduo© by the British pharmaceutical company AstraZeneca, contains both metformin and a newer compound called dapagliflozin. When prescribed alongside healthy diet and exercise, this new dual-drug lowers blood glucose levels and helps patients lose weight. “Metformin, which has been available in the US for the past twenty years, works by inhibiting glucose production in the liver and improving the ability of the body to react to insulin,” says Robert Gabbay, MD, PhD, the Chief Medical Officer and Senior Vice President of the Joslin Diabetes Center. Since Metformin is the first line of drug of choice for the treatment of type 2 diabetes as well as pre-diabetes, many patients are prescribed metformin. But sometimes high doses of metformin can cause gastrointestinal distress including diarrhea, cramps, nausea, vomiting, and increased flatulence. If these side effects are particularly troubling or if patients are resistant to the drug the highest dose of metformin isn’t lowering blood glucose levels enough, that’s where the dapagliflozin steps in. Metformin and dapagliflozin are complementary. Dapagliflozin does the same job of lowing blood glucose levels but it works elsewhere in the body so it doesn’t interfere with the metformin. When prescribed together, patients can lower their blood glucose levels more successfully. Dapagliflozin works by blocking a protein in the kidneys called sodium-glucose co-transporter 2 (SGLT2). Normally, SGLT2 absorbs glucose from the urine and pushes it into the bloodstream as blood filters through the kidneys. But the dapagliflozin Continue reading >>

Been running high the last two three months. Always high in mornings no matter what I eat night before(140-170) My body does not respond anymore to excercise. ie was 156 this morning at wake up. Had a coffee and bowl of cereal. Special K cimmanon pecan and a banana as usual. Went to gym and had good workout. Came home and tested myself about and was at 228!!! Last A1c in Oct was 6.7 Doctor has been very happy with me but last two months everything is high. Go again to Docs mid Jan. I have been taking metformin 2000 a day. 1000 morning and 1000 again at bedtime....Does this usually mean I will have to change meds or go on insulin?? Have been on Metformin almost two years. Thanks Can you tell us what type of things you are eating? If could be that you can help the metformin but watching your carbs. Diabetes can be progressive and so yes it is possible the the metformin you are taking needs help, from another oral med or insulin, however it's also possible that by making some changes to your diet that it would help the metformin. For example instead of having cereal for breakfast go for a lower carb alternative such as bacon and eggs. How long after exercising (and eating) did you test. I find that if I test immediately after exercise my levels have risen. Continue reading >>

Please Stay Away From These Drugs For Type 2 Diabetes

Please Stay Away From These Drugs For Type 2 Diabetes

Introduction The research is quite clear – oral medications to treat type 2 diabetes do not alter the long-term progression of the disease. While these drugs can be quite effective in the short term, several different types are associated with an increased chance of mortality and in particular, an increased risk for dying due to cardiovascular disease. In addition, often the type 2 diabetic fails to make necessary lifestyle and dietary changes to improve/reverse their condition because these drugs also create a false sense of security. Ultimately all of these drugs lose their effectiveness over time and start a viscous cycle where they are prescribed at higher dosages or in combination with other drugs, all of which leads to an even greater rate of mortality. In fact, the long-term use of some of these drugs is actually associated with an earlier death compared to control groups with type 2 diabetes not being given the drugs. Background Data: The most widely prescribed drug for type 2 diabetes is metformin (Glucophage). While studies have shown that metformin alone has illustrated a decrease in heart attacks and all diabetes related deaths compared with other drugs, it does not work at all in about 25 percent of cases and tends to lose its effectiveness with time. When the latter happens it is usually combined with a sulfonylurea, which actually increases mortality risk. On their own, these sulfonylureas drugs are of limited value and there is some evidence to indicate that sulfonylureas actually produce harmful long-term side-effects. For example, in a famous study conducted by the University Group Diabetes Program (UDGP), it was shown that the rate of death due to a heart attack or stroke was 2.5 times greater in the group taking tolbutamide (a sulfonylurea), than t Continue reading >>

A Comprehensive Guide To Metformin

A Comprehensive Guide To Metformin

Metformin is the top of the line medication option for Pre-Diabetes and Type 2 Diabetes. If you must start taking medication for your newly diagnosed condition, it is then likely that your healthcare provider will prescribe this medication. Taking care of beta cells is an important thing. If you help to shield them from demise, they will keep your blood sugar down. This medication is important for your beta cell safety if you have Type 2 Diabetes. Not only does Metformin lower blood sugar and decrease resistance of insulin at the cellular level, it improves cell functioning, lipids, and how fat is distributed in our bodies. Increasing evidence in research points to Metformin’s effects on decreasing the replication of cancer cells, and providing a protective action for the neurological system. Let’s find out why Lori didn’t want to take Metformin. After learning about the benefits of going on Metformin, she changed her mind. Lori’s Story Lori came in worrying. Her doctor had placed her on Metformin, but she didn’t want to get the prescription filled. “I don’t want to go on diabetes medicine,” said Lori. “If I go on pills, next it will be shots. I don’t want to end up like my dad who took four shots a day.” “The doctor wants you on Metformin now to protect cells in your pancreas, so they can make more insulin. With diet and exercise, at your age, you can reverse the diagnosis. Would you like to talk about how we can work together to accomplish that?” “Reverse?” she asked. “What do you mean reverse? Will I not have Type 2 Diabetes anymore?” “You will always have it, but if you want to put it in remission, you are certainly young enough to do so. Your doctor wants to protect your beta cells in the pancreas. If you take the new medication, Continue reading >>

Metformin Forever

Metformin Forever

Metformin controls the insulin resistance of people who have type 2 diabetes so well that, if possible, all of us should be taking it. That’s what Roderic Crist, M.D., told me at the annual convention of the American Society of Bariatric Physicians in Denver this weekend. Dr. Crist specializes in family medicine in Cape Girardeau, Missouri. “Not everybody can take every drug,” he added, when I followed up our conversation by calling him at his office after he returned home. “But most of the time people can take metformin if they take it carefully.” Doctors increasingly prescribe it not only for type 2 diabetes but also for insulin resistance, polycystic ovary syndrome, and non-alcoholic fatty liver disease. Roughly one-third of Dr. Crist’s patients have diabetes. Well over half, if not two-thirds of the people he sees are insulin resistant. “I treat insulin resistance with that drug even if they aren’t fully diabetic.” he says. “If they have high triglyceride levels and low HDL levels, particularly if they are centrally obese, they should probably be on metformin. It helps slow the progression of the disease from one thing to the next.” But he goes further. He prescribes metformin to almost all of his patients who have type 2 diabetes — no matter how low their A1C level is. And he tells his patients that their levels should be 5.0 or less — not the American Diabetes Association’s less stringent recommendation of 7.0 or less. “If their A1C is at 5, their diabetes is in complete remission. So I have that as a goal.” And he still prescribes metformin to them after they reach that goal. “The two important issues are that it will prevent progression and it should be used in the earliest phases of insulin resistance. We vastly underutilize me Continue reading >>
