Review Metformin-associated Lactic Acidosis: Current Perspectives On Causes And Risk

Review Metformin-associated Lactic Acidosis: Current Perspectives On Causes And Risk

Abstract Although metformin has become a drug of choice for the treatment of type 2 diabetes mellitus, some patients may not receive it owing to the risk of lactic acidosis. Metformin, along with other drugs in the biguanide class, increases plasma lactate levels in a plasma concentration-dependent manner by inhibiting mitochondrial respiration predominantly in the liver. Elevated plasma metformin concentrations (as occur in individuals with renal impairment) and a secondary event or condition that further disrupts lactate production or clearance (e.g., cirrhosis, sepsis, or hypoperfusion), are typically necessary to cause metformin-associated lactic acidosis (MALA). As these secondary events may be unpredictable and the mortality rate for MALA approaches 50%, metformin has been contraindicated in moderate and severe renal impairment since its FDA approval in patients with normal renal function or mild renal insufficiency to minimize the potential for toxic metformin levels and MALA. However, the reported incidence of lactic acidosis in clinical practice has proved to be very low (< 10 cases per 100,000 patient-years). Several groups have suggested that current renal function cutoffs for metformin are too conservative, thus depriving a substantial number of type 2 diabetes patients from the potential benefit of metformin therapy. On the other hand, the success of metformin as the first-line diabetes therapy may be a direct consequence of conservative labeling, the absence of which could have led to excess patient risk and eventual withdrawal from the market, as happened with earlier biguanide therapies. An investigational delayed-release metformin currently under development could potentially provide a treatment option for patients with renal impairment pending the resu Continue reading >>

Metformin, FDA-approved in 1994, is an antidiabetic agent used in type 2 diabetes mellitus. Metformin comes in both immediate-release and extended-release and is used in several combination products with other antidiabetic agents [1] . Typically at diagnosis of type 2 diabetes, lifestyle management such as diet and exercise are recommended. Metformin is often used as monotherapy or in combination when diet and exercise are not effective at lowering hyperglycemia. According to the American Diabetes Association (ADA), metformin is the preferred first-line agent in type 2 diabetics in adults and children ten years and older. Per Standards of Medical Care in Diabetes 2018, if a patients A1c is less than 9% at diagnosis, then metformin monotherapy is recommended. If the A1c is greater than 9%, then metformin is recommended for use in combination therapy. Metformin is not indicated in type 1 diabetes mellitus [2] . Metformin also has several non-FDA approved indications including gestational diabetes, management of antipsychotic-induced weight gain, type 2 diabetes prevention, and both the treatment and prevention of polycystic ovary syndrome (PCOS). Currently, metformin is the only ADA-recommended antidiabetic for pre-diabetes [2] . As for potential indications, metformin is being studied for its possible antiaging, anticancer, and neuroprotective effects [3] . Classified as a biguanide, metformin reduces blood glucose levels by decreasing the production of glucose in the liver, decreasing intestinal absorption and increasing insulin sensitivity. Metformin decreases both the basal and postprandial blood glucose. In PCOS, Metformin decreases insulin levels, which then decreases luteinizing hormone and androgen levels. Thus acting to normalize the menstruation cycle. It is im Continue reading >>

Provider Decisions And Patient Outcomes After Premature Metformin Discontinuation

Provider Decisions And Patient Outcomes After Premature Metformin Discontinuation

The purpose of this study was to evaluate the effects of alternative antihyperglycemic therapy after discontinuation of metformin due to documented declining renal function. This retrospective, single-site study evaluated patients who had metformin discontinued between 1 January 1999 and 30 September 2013. Medical records were evaluated for documented adverse events, subsequent glycemic control, and costs associated with the alternative therapy. Patients served as their own controls. A total of 179 patients met study entry criteria, and their peak A1C was significantly higher within the year after metformin discontinuation (P <0.001). After the provider added new medications to control patients' blood glucose, their A1C by the end of the first year after discontinuing metformin was similar to their A1C while taking metformin. Significant weight gain accompanied the use of the medications added to replace metformin, with an average increase of 3.81 kg (P <0.001). Additionally, after discontinuing metformin, more patients experienced hypoglycemia with the addition of other medications to control their blood glucose (P <0.001). As expected, the cost of therapy was significantly higher (P <0.0001) after metformin was discontinued because metformin was generically available, whereas the replacement medications frequently were not. Providers should consider the expanded recommendations for the use of metformin in patients with mild to moderate stable renal dysfunction to help such patients avoid weight gain, hypoglycemia, loss of blood glucose control, and increased costs.

Fda Drug Safety Communication: Fda Revises Warnings Regarding Use Of The Diabetes Medicine Metformin In Certain Patients With Reduced Kidney Function

Fda Drug Safety Communication: Fda Revises Warnings Regarding Use Of The Diabetes Medicine Metformin In Certain Patients With Reduced Kidney Function

[ 4-8-2016 ] The U.S. Food and Drug Administration (FDA) is requiring labeling changes regarding the recommendations for metformin-containing medicines for diabetes to expand metformin’s use in certain patients with reduced kidney function. The current labeling strongly recommends against use of metformin in some patients whose kidneys do not work normally. We were asked1,2 to review numerous medical studies regarding the safety of metformin use in patients with mild to moderate impairment in kidney function,3-14 and to change the measure of kidney function in the metformin drug labeling that is used to determine whether a patient can receive metformin. We have concluded our review, and are requiring changes to the labeling of all metformin-containing medicines to reflect this new information. Health care professionals should follow the latest recommendations when prescribing metformin-containing medicines to patients with impaired kidney function. Patients should talk to their health care professionals if they have any questions or concerns about taking metformin. Metformin-containing medicines are available by prescription only and are used along with diet and exercise to lower blood sugar levels in patients with type 2 diabetes. When untreated, type 2 diabetes can lead to serious problems, including blindness, nerve and kidney damage, and heart disease. Metformin-containing medicines are available as single-ingredient products and also in combination with other drugs used to treat diabetes (see FDA Approved metformin-containing Medicines). The current drug labeling strongly recommends against metformin use in some patients whose kidneys do not work normally because use of metformin in these patients can increase the risk of developing a serious and potentially dead Continue reading >>

Use Of Metformin In The Setting Of Mild-to-moderate Renal Insufficiency

Use Of Metformin In The Setting Of Mild-to-moderate Renal Insufficiency

Go to: HISTORICAL PERSPECTIVE Despite these proven benefits, metformin remains contraindicated in a large segment of the type 2 diabetic population, largely because of concerns over the rare adverse effect of lactic acidosis. For these reasons, the drug has been restricted to individuals with normal creatinine levels as a surrogate for renal competence. Other contraindications (e.g., any significant hypoxemia, alcoholism, cirrhosis, a recent radiocontrast study) also increase the risk for or the consequences of lactic acidosis, but these are not the topic of this review. Metformin belongs to the biguanide drug class (previous members include phenformin and buformin), developed for lowering glucose in the 1950s. Initial enthusiasm for biguanides was tempered over the next two decades by the growing recognition of their risk of lactic acidosis. A marked reduction in biguanide use occurred in the mid-1970s because phenformin, extensively adopted in clinical practice, was implicated in a number of fatal cases of this severe metabolic decompensation (17). The association with lactic acidosis eventually led to its withdrawal from the market. Importantly, lactic acidosis with phenformin seems to occur ~10–20 times more frequently than with metformin (18). In contrast to metformin, modestly raised phenformin concentrations may reduce peripheral glucose oxidation and enhance peripheral lactate production, which can increase circulating lactate levels. In fact, phenformin levels correlate with lactate concentration, whereas metformin levels do not (19). In addition, ~10% of European Caucasians have an inherent defect in phenformin hydroxylation, which may lead to drug accumulation and, as a result, elevated lactate levels (20). The experience with phenformin resulted in cautiou Continue reading >>

Fda Issues Guidance For Metformin Use In Renal Impairment

Fda Issues Guidance For Metformin Use In Renal Impairment

FDA Issues Guidance for Metformin Use in Renal Impairment The FDA has issued new guidance for the use of the first-line diabetes drug metformin in patients with renal impairment. Metformin was approved by the FDA in 1994 for the management of type 2 diabetes. Since its approval, its labeling has warned of a contraindication in elevated serum creatinine (>1.5 mg/dL for males, >1.4 mg/dL for females) due to a risk of lactic acidosis secondary to metformin accumulation.1 Other risk factors for lactic acidosis include contrast dye exposure within 48 hours, chronic or excessive alcohol intake, dehydration, sepsis, acute congestive heart failure, and age. This absolute contraindication was based on clinical trials of an older biguanide called phenformin, which showed a greater risk of lactic acidosis associated with significant mortality and was subsequently pulled off the market in 1977.2 Although phenformin is no longer available in the United States, its still available in European and South American markets. Notably, the incidence of lactic acidosis associated with metformin is as low as 0.03 cases per 1000 patient-years. The FDA reviewed several studies to determine whether patients with mild to moderate renal impairment could safely continue on metformin to manage their type 2 diabetes. One of the larger trials reviewed was an observational study of 51,675 type 2 diabetes patients to determine the effect metformin would have on primary outcomes of cardiovascular disease (CVD), all-cause mortality, and acidosis or serious infections with varying degrees of renal function.3 Based on subgroup analyses of patients with varying degrees of renal impairment, the investigators determined that patients with an estimated glomerular filtration rate (eGFR) >45 mL/min/m2 showed no Continue reading >>

(2017) Management of type 2 Diabetes in patients with Chronic Kidney Disease. Arch Clin Nephrol 3(1): 053-056. DOI: 10.17352/acn.000026 About 30-40% of patients with chronic kidney disease (CKD) patients also have concomitant diabetes (1). Diabetes has been shown to have significantly stronger association with CKD in patients with younger age (2). Diabetes management in CKD poses significant challenge because of the increased risk of hypoglycaemia, renal excretion of most oral antidiabetics, variable appetite of patients with CKD and the effects of hemodialysis and peritoneal dialysis on glycemic control. Management of diabetes after renal transplantation is a separate entity with different challenges due to the effect of immunosuppressants especially steroids on carbohydrate metabolism and will not be discussed in this review. There are several factors which predispose patients with CKD to an increased risk of hypoglycaemia: Patients with decreased GFR (<60 ml/min per 1.73 m2) due to diabetes and CKD have decreased insulin requirement as insulin is cleared by kidneys.

Changes In Metformin Use In Chronic Kidney Disease

Changes In Metformin Use In Chronic Kidney Disease

Go to: Fear of LA Metformin is chemically similar to phenformin, but has a different mechanism of action. Although the fear of LA remains, no absolute definitive causal relationship has been proven beyond doubt. Many reported cases of metformin-associated LA (MALA) did not measure metformin levels, whereas in others levels were not high, suggesting ‘metformin coincident lactic acidosis’ [9]. In 1998, Misbin et al. reported that after starting to use metformin, rates of LA in the USA were no different from prior to the approval of metformin [10]. Many reported cases of LA had multiple risk factors besides renal failure. Since DM2 is a risk factor, it is thought that many such cases may have been just from DM2. The putative risk factors for LA described in the literature include old age, decreased cardiac output, respiratory failure or hypoxic conditions, ethanol intoxication, fasting and decreased hepatic function. In a nested case–control analysis that included 50 048 patients, six patients were identified with active use of metformin and LA. Out of those, five patients had sepsis and signs of end-organ damage, suggesting that LA most frequently occurs in acutely worsening clinical scenarios [11]. Continue reading >>

Adherence To Metformin Contraindications As Shown By Population-based Studies And Retrospective Samples

Adherence To Metformin Contraindications As Shown By Population-based Studies And Retrospective Samples

... These cutoff thresholds were determined by the renal function with which 3 g of metformin could be removed over 24 to 48 h[5], and the United States Food and Drug Administration (FDA) approved the use of metformin with the above contraindication in 1994[6]. However, the incidence of lactic acidosis among metformin users was very low, with figures as low as 2.4 to 9.0 per 100,000 patient-years , whereas that of phenformin was 40 to 64 cases per 100,000 patient-years[8]. Moreover, some studies revealed that the incidences of the complication were not different among users of metformin and other OADs[9]. ... ... Most of the literature is based upon the historical relationship of metformin's more toxic precursor biguanide phenformin to lactic acidosis. Although subsequent observations with the use of metformin have suggested a lower incidence of such events than had been reported with phenformin, there has been no weakening of a proscription against its use by the USFDA for ''Renal disease or renal dysfunction (e.g., as suggested by serum creatinine levels !1.5 mg/dl [males], !1.4 mg/dl [females] or abnormal creatinine clearance)''38 40. Despite this ''contraindication'', metformin is still being used in patients with decreased renal function in North America as 28% of the biguanide use in our study occurred with eGFR < 35 ml/min compared to >40% in all other regions). ... ... Guidelines published in Western countries recommend measures be taken for patients receiving biguanides who are going to use iodinated contrast media. Although the recommended measures vary among guidelines, most guideline documents do not recommend the suspension of biguanides in patients with normal kidney function before the use of iodinated contrast media2930 (Table 2).

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 PRECAUTIONS). 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 (see DOSAGE AND ADMINISTRATION, CONTRAINDICATIONS, and PRECAUTIONS). If Metformin-associated lactic acidosis is suspected, immediately discontinue Metformin and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended (see PRECAUTIONS). Table 1: Select Mean (±S.D.)

Type 2 Diabetes Patients With Metformin Intolerance

Type 2 diabetes patients with metformin intolerance This article briefly reviews the strategies used to effectively treat type 2 diabetes patients that are unable to tolerate metformin Department of Pharmacy Practice Ambulatory Care Division, Texas Tech University Health Sciences Center, School of Pharmacy Dallas, Type 2 diabetes mellitus (T2DM) is a global disease that currently affects more than 300 million individuals worldwide and is projected to increase by 55% over the next 20 years.1 By and large most patients diagnosed with T2DM are initially started on metformin as it is considered the optimal first-line therapy by clinical guidelines and consensus recommendations.24 Additionally, it is widely accepted to continue metformin throughout the progression of this chronic disease, even when other therapies are added. With the increasing number of diabetic patients in the world, it can be expected that many patients, for various reasons might be unable to tolerate or have contraindications to metformin use. Major issues of intolerability are usually related to gastrointestinal (GI) side effects or the presence of chronic kidney disease (CKD). This brief review will recommend appropriate treatment options when metformin cannot be used in these two scenarios, taking into account efficacy, adverse effect profiles, comorbid conditions and patient preference. One common cause for metformin intolerability is the GI side effects experienced by many patients. According to the package insert for one brand of metformin commonly available in the US, one study showed that more than 25% of patients experienced nausea and vomiting, and more than 50% of patients experienced diarrhoea. Other less common GI side effects include flatulence, indigestion, and abdominal discomfort.5 Many Continue reading >>
