M. Rotella, Email: [email protected] . Received 2014 Jan 20; Accepted 2014 Feb 27. This article has been cited by other articles in PMC. A new formulation of metformin: metformin extended-release (ER) is now available, with different formulations in each country and it appears relevant to discuss the management of this drug in clinical practice. Metformin, an oral biguanide hypoglycemic agent, is an efficacious tool in the treatment of type 2 diabetes mellitus. Metformin’s efficacy, security profile, benefic cardiovascular and metabolic effects make this drug as the first agent of choice in the treatment of type 2 diabetes, together with lifestyle modifications [ 1 ]. Type 2 diabetes is characterized by impaired insulin secretion and insulin resistance. Insulin resistance in the fasting state induces an increase in hepatic gluconeogenesis and induces hyperglycemia in the early morning. Metformin, as its major effect, decreases hepatic glucose output lowering fasting glycaemia and, secondarily, it increases glucose uptake in peripheral tissues. It is generally well tolerated, despite the fact that the most common adverse effects are gastrointestinal ones, which may be tampered by dose titration. In monotherapy metformin decreases HbA1c levels by 0.6–1.0 % and this is not accompanied by hypoglycemia in the large majority of patients. Metformin is neutral with respect to weight or, possibly, induces a modest weight loss. The UKPDS has demonstrated a beneficial effect of metformin therapy on CVD outcomes [ 2 ].

Janumet Xr (sitagliptin And Metformin Hcl): Side Effects, Interactions, Warning, Dosage & Uses

(sitagliptin and metformin HCl) Extended-Release Tablets Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The onset of metformin-associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Metformin-associated lactic acidosis was characterized by elevated blood lactate levels (>5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio, and metformin plasma levels generally >5 mcg/mL [see Use In Specific Populations ]. Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (e.g., carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, and hepatic impairment. Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the full prescribing information [see DOSAGE AND ADMINISTRATION , CONTRAINDICATIONS , WARNINGS AND PRECAUTIONS , DRUG INTERACTIONS , and Use In Specific Populations ]. If metformin-associated lactic acidosis is suspected, immediately discontinue JANUMET XR and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended [see Use In Specific Populations ]. JANUMET XR tablets contain two oral antidiabetic medications used in the management of type 2 diabetes : sitagliptin and metformin hydrochloride extended-release. Sitagliptin is an orally-active inhibitor of the dipeptidyl peptidas Continue reading >>

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 >>

Commonly Used Brand Name(s)Fortamet, Glucophage, Glucophage XR, Glumetza, Riomet Therapeutic ClassificationsHypoglycemic QUICK LINKS Oral route (Tablet;Tablet, Extended Release;Solution) Death, hypothermia, hypotension, and resistant bradyarrhythmias have been reported due to metformin-associated lactic acidosis. Onset may be subtle and include nonspecific symptoms such as malaise, myalgia, respiratory distress, somnolence, and abdominal distress; laboratory abnormalities include low pH, increased anion gap and elevated blood lactate. The risk of lactic acidosis increases with renal or hepatic impairment, aged 65 years or older, having a radiological study with contrast, surgery, or other procedures, hypoxic states, and excessive alcohol intake.

With this type of diabetes, insulin produced by the pancreas is not able to get sugar into the cells of the body where it can work properly. Using metformin alone, with a type of oral antidiabetic medicine called a sulfonylurea, or with insulin, will help to lower blood sugar when it is too high and help restore the way you use food to make energy. Many people can control type 2 diabetes with diet and exercise. Following a specially planned diet and exercise will always be important when you have diabetes, even when you are taking medicines.

Metformin Vs Metformin Er

Metformin Vs Metformin Er

I'm seeing quite a few posts on BBSes from people who are having problems with metformin because of side effects that could be eliminated if they were taking the extended release form of this drug. For some reason, many family doctors don't seem to be aware that there is a ER version of this drug that has such benefits. This is probably because metformin is a cheap generic and isn't promoted by herds of beautiful ex-cheerleaders turned drug company salespushers who "educate" doctors about far more expensive--and less effective--newer drugs. Here are the facts: Metformin (also sold under the brand name Glucophage) comes in a regular version which is taken at meal time, three times a day, and an extended release form (marketed as ER or XR) which is taken once a day. Almost always, when people report diarrhea or intense heartburn with metformin, they are taking regular version. I experienced the heartburn on the regular drug. It was very disturbing because the pain was localized over my heart and felt just like the description of a heart attack you read in articles. My doctor assured me it was coming from the metformin, but that didn't make it any easier to live with because I kept wondering how, if I were having a real heart attack, I'd know it wasn't a pain from the drug? The ER version releases the drug more slowly and this usually eliminates the gastrointestinal problems. The trade off with taking the ER form is that the amount of blood sugar lowering you see might be a bit less than with the regular form as the drug acts in a slower smoother fashion rather than hitting all at once. But if you can't take the regular at all drug because of the side effects, the slight weakening in effect is a reasonable trade off. Plus, you only have to remember to take one dose rather Continue reading >>

Uses Metformin is used with a proper diet and exercise program and possibly with other medications to control high blood sugar. It is used in patients with type 2 diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Metformin works by helping to restore your body's proper response to the insulin you naturally produce. It also decreases the amount of sugar that your liver makes and that your stomach/intestines absorb. How to use Metformin HCL ER Read the Patient Information Leaflet if available from your pharmacist before you start taking metformin and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth as directed by your doctor, usually once daily with the evening meal. Drink plenty of fluids while taking this medication unless otherwise directed by your doctor. Do not crush or chew this medication. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). To reduce your risk of side effects (such as upset stomach), your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully. Take this medication regula Continue reading >>
