Is Metformin Associated With Lactic Acidosis?
Is Metformin Associated With Lactic Acidosis? The use of metformin in patients with renal impairment is associated with an increased risk for lactic acidosis. Why is this and what is the mechanism? Are sulfonylureas associated with lactic acidosis? Adjunct Faculty, Albany College of Pharmacy, Albany, New York; Clinical Pharmacy Specialist, VA Medical Center, Bath, New York Metformin is one of most commonly prescribed medications for the treatment of type 2 diabetes mellitus. Metformin exerts its activity by increasing peripheral glucose uptake and utilization, and decreasing hepatic gluconeogenesis. By decreasing pyruvate dehydrogenase activity and mitochondrial reducing agent transport, metformin enhances anaerobic metabolism and increased production of tricarboxylic acid cycle precursors. Inhibition of pyruvate dehydrogenase subsequently decreases the channeling of these precursors into aerobic metabolism and causes increased metabolism of pyruvate to lactate and ultimately lactic acid production.[ 1 ] In a patient with normal renal function, the excess lactic acid is simply cleared through the kidneys. However, in a patient with renal impairment, both metformin and lactic acid are cleared less effectively and may result in further accumulation of both.[ 1 ] The complication of lactic acidosis is serious and potentially fatal. Increased risk for lactic acidosis associated with metformin is controversial. A Cochrane Systematic Review of over 200 trials evaluated the incidence of lactic acidosis among patients prescribed metformin vs non-metformin antidiabetes medications. Of 100,000 people, the incidence of lactic acidosis was 5.1 cases in the metformin group and 5.8 cases in the non-metformin group. The authors concluded that metformin is not associated with an incre Continue reading >>

Click "Read More" to check out the answers : 1 : Increase in Insulin Resistance is the primary mechanism for DM II. Destruction of Cells (Amyloid Deposition) occurs at later stages. 2, 3 & 6 : Metformin is used as first line drug to control DM II especially in obese as in this case. It acts by inhibiting hepatic gluconeogenesis and increasing peripheral uptake of glucose. It is recommended because they do not cause hypoglycemia and weight gain unlike sulfonylureas. Most common side effect of this drug is Lactic Acidosis especially in patients with kidney damage ( because this will lead to drug accumulation) & thus Metformin is contraindicated in Renal Insufficiency. Other drugs that can be use in diabetes mellitus II are sulfonylureas (tolbutamide), Alpha-Glucosidase inhibitors (Acarbose), PPAR-Agonist (-Glitazones). Proper Diet and Exercise alone can control glucose in 25% of diabetics & is always the first choice to choose if no other pathology associated. In our case patient failed to maintain her glucose levels & LDL Level is High. Thus patient must be started on Statins along with Metformin. Some patientsmight get back to unhealthy life regime leaving their body totally on the mercy of drugs alone and so you must discuss all benefits of Diet & Excercise therapy with your patient. Niacin is Contraindicated in Diabetics. 3 : Nodular Glomerulosclerosis is most c ommonly associated with DM II & should be suspected in any DM II Patient. 4 : Only GLUT 4 is insulin dependend receptor out of these 5. GLUT 4 is present on Skeletal muscles and adispose tissue.

Metformin-associated Lactic Acidosis: Predisposing Factors And Outcome
Go to: Abstract Metformin is considered the first choice oral treatment for type 2 diabetes patients in the absence of contraindications. Rarely, life-threatening complications associated with metformin treatment are seen in some patients with underlying diseases. The aim of this study was to further investigate the clinical profiles and risk factors for metformin-associated lactic acidosis (MALA) and the treatment modalities according to survival. To identify MALA, we performed a retrospective study in seven diabetic patients who were taking metformin and had been diagnosed with lactic acidosis at Inha University Hospital between 1995 and 2012. For each patient, we recorded the age, sex, daily metformin dosage, laboratory test results, admission diagnosis, and risk factors. Also, concurrent conditions, treatment modalities, and outcomes were evaluated. Six patients had risk factors for lactic acidosis before admission. All patients had renal impairment on admission as a precipitating risk factor. Five patients survived and two patients died despite early renal replacement therapy. Older patients tended to have a poorer prognosis. Renal function must be monitored in elderly type 2 diabetes mellitus patients with underlying diseases and conditions causing renal impairment who begin metformin treatment. Accurate recognition of MALA and initiation of renal replacement are essential for treatment. Keywords: Metformin, Acidosis, lactic, Diabetes mellitus, type 2 Go to: INTRODUCTION Metformin is an oral antidiabetic drug in the biguanide class that is widely used, alone or in combination with a sulfonylurea or other drugs, in patients with type 2 diabetes. The drug's glucose-lowering effect results mainly from decreased hepatic glucose output with increased glucose utilizatio Continue reading >>

Sketchy Pharm: Metformin, Thiazolidinediones, Pramlintide, Sglt2 Inhibitors Flashcards Preview
It decreases hepatic gluconeogenesis by inhibiting the mitochondrial enzyme glycerophosphate dehydrogenase (think of the girl whom the METaphOR-wielding boy is trying to woo who is biting a mitochondria-shaped candy). Also, it activates AMPK, an enzyme that also works to inhibit gluconeogenesis. (Think of the AMPKandy bag.) Lastly, it increases peripheral insulin sensitivity (like the open Valentine's mailbox on the bench by the metformin metaphor boy). Lactic acidosis from impaired gluconeogenesis (think of the spilled, spoiled milk). This needs to be thought of in patients with renal failure, because metformin is just excreted unmodified by the kidneys (think of the cracked, kidney-shaped tray that the lactic acid is on). Also, GI upset can be caused (like the green-faced girl about to barf at the metformin boy). Rosiglitazone and pioglitazone (think of the girl reading "ROSes are red" on the GLITter-covered card) What is the mechanism of thiazolidinediones? They act on peroxisome proliferator-activated receptor gamma (PPAR-gamma), an intracellular nuclear receptor that increases glucose uptake and decreases glucose production (like the "life of the PPARy" shirt that the thiazolidinedione boy is wearing). One of the proteins expressed is adiponectin (like his turtleneck). Another protein is GLUT4 (like the GLUT4 mailbox). Explain the unique relationship between the thiazolidinediones and weight gain. Thiazolidinediones lead to increased fatty-acid storage in adipocytes differentiation of adipocytes, leading to decreased triglyceride levels and weight gain. (Think of the boy eating doughnuts to represent fat storage.) True or false: thiazolidinediones take days to weeks to become effective. True. Because it works by increasing gene expression, it takes time. Which non Continue reading >>

They Are Available As Monotherapy Or Combination Therapies, With The Latter Involving Two (or, Less Commonly, Three) Antidiabetic Drugs And/or
Antidiabetic drugs (with the exception of insulin) are all pharmacological agents that have been approved for hypoglycemic treatment in type 2 diabetes mellitus (DM). If lifestyle modifications (weight loss, dietary modification, and exercise) do not sufficiently reduce A1C levels (target level: ∼ 7%), pharmacological treatment with antidiabetic drugs should be initiated. These drugs may be classified according to their mechanism of action as insulinotropic or non-insulinotropic. They are available as monotherapy or combination therapies, with the latter involving two (or, less commonly, three) antidiabetic drugs and/or insulin. The exact treatment algorithms are reviewed in the treatment section of diabetes mellitus. The drug of choice for all type 2 diabetic patients is metformin. This drug has beneficial effects on glucose metabolism and promotes weight loss or at least weight stabilization. In addition, numerous studies have demonstrated that metformin can reduce mortality and the risk of complications. If metformin is contraindicated, not tolerated, or does not sufficiently control blood glucose levels, another class of antidiabetic drug may be administered. Most antidiabetic drugs are not recommended or should be used with caution in patients with moderate or severe renal failure or other significant comorbidities. Oral antidiabetic drugs are not recommended during pregnancy or breastfeeding. Continue reading >>
