Michiel G. Wulffele, Adriaan Kooy, Philippe Lehert, Daniel Bets, Jeles C. Ogterop, Bob Borger van der Burg, Ab J.M. Donker, Coen D.A. Stehouwer Combination of Insulin and Metformin in the Treatment of Type 2 Diabetes. Diabetes Care 1 December 2002 25 : 21332140.
OBJECTIVETo investigate the metabolic effects of metformin, as compared with placebo, in type 2 diabetic patients intensively treated with insulin.
RESEARCH DESIGN AND METHODSMetformin improves glycemic control in poorly controlled type 2 diabetic patients. Its effect in type 2 diabetic patients who are intensively treated with insulin has not been studied. A total of 390 patients whose type 2 diabetes was controlled with insulin therapy completed a randomized controlled double-blind trial with a planned interim analysis after 16 weeks of treatment.The subjects were selected from three outpatient clinics in regional hospitals and were randomly assigned to either the placebo or metformin group, in addition to insulin therapy. Intensive glucose monitoring with immediate insulin adjustments according to strict guidelines was conducted. Indexes of glycemic control, insulin requirements, body weight, blood pressure, plasma lipids, hypoglycemic events, and other adverse events were measured.

Recommended Inpatient Insulin Regimens
The selection of an insulin regimen depends on whether the patient is insulin naïve, has good or poor baseline diabetes control, or has renal impairment. Dosage considerations include the patient’s current oral intake, comorbidities, other medications, and experience with and adherence to prior outpatient insulin therapy.20,24
The first step in prescribing inpatient insulin is to determine the total daily dose . Lower doses are appropriate when initiating therapy in insulin-naïve patients. In hospitalized patients who have type 2 diabetes and renal impairment that does not require hemodialysis, initiation of insulin therapy using a lower dose of 0.25 units per kg per day compared with 0.5 units per kg per day has been shown to provide a similar glucose-lowering effect while reducing the incidence of hypoglycemia from 30% to 15.8%.9,22,30

Stage IV chronic kidney disease not on dialysis
Underweight, older age, or hemodialysis
Obese, insulin resistant, or taking systemic glucocorticoids
note: Glargine and detemir are the preferred agents, and glargine is favored because of its longer duration and once-per-day administration.30

Effects On Blood Pressure
The hypertension associated with diabetes has an unclear pathogenesis that may involve insulin resistance. Insulin resistance is related to hypertension in both diabetic and non-diabetic individuals and may contribute to hypertension by increasing sympathetic activity, peripheral vascular resistance, renal sodium retention , and vascular smooth muscle tone and proliferation .
Data of the effects of metformin on BP are variable, with neutral effects or small decreases in SBP and DBP . In the BIGPRO1 trial carried out in upper-body obese non-diabetic subjects with no cardiovascular diseases or contraindications to metformin, blood pressure decreased significantly more in the IFG/IGT subgroup treated with metformin compared to the placebo group .

Blood Pressure And Plasma Lipids
Data are shown in . There was a small but nonsignificant increase in blood pressure in both groups that did not differ between the groups . In the placebo group, plasma total and LDL cholesterol concentrations decreased by 0.04 mmol/l and 0.02 mmol/l , respectively. In the metformin group, plasma total cholesterol and LDL cholesterol concentrations decreased by 0.25 and 0.21 mmol/l , respectively . The differences between the metformin and the placebo group were 0.21 mmol/l for total cholesterol and 0.19 mmol/l for LDL cholesterol. LDL cholesterol concentrations were not calculated in patients with triglyceride values > 4.5 mmol/l at baseline and/or at follow-up . Adjustment for GHb change did not importantly change on the effect estimate of metformin treatment on plasma LDL cholesterol . There were no significant changes in plasma HDL cholesterol and triglyceride concentrations in either group .

What Is Metformin What Is Insulin
Metformin is an oral medication that lowers blood glucose by influencing the body’s sensitivity to insulin and is used for treating type 2 diabetes. Metformin increases the sensitivity of liver, muscle, fat, and other tissues to the uptake and effects of insulin, which lowers the blood sugar levels. Metformin does not increase the concentration of insulin in the blood and does not cause low blood glucose levels when used alone. Metformin can reduce complications of diabetes such as heart disease, blindness, and kidney disease. Metformin is also used to treat polycystic ovaries and weight gain due to medications used for treating psychoses.
Insulin is a naturally-occurring hormone secreted by the pancreas and used by the cells of the body to remove and use glucose from the blood. People with diabetes mellitus have a reduced ability to take up and use glucose from the blood and the glucose level in the blood rises. In type 1 diabetes, the pancreas cannot produce enough insulin. In type 2 diabetes, patients produce insulin, but cells throughout the body do not respond normally to the insulin. By increasing the uptake of glucose by cells and reducing the concentration of glucose in the blood, insulin prevents or reduces the long-term complications of diabetes, including damage to the blood vessels, eyes, kidneys, and nerves. Insulin is administered by injection under the skin .

Metformin In The Management Of Adult Diabetic Patients
Current guidelines from the American Diabetes Association/European Association for the Study of Diabetes and the American Association of Clinical Endocrinologists/American College of Endocrinology recommend early initiation of metformin as a first-line drug for monotherapy and combination therapy for patients with T2DM. This recommendation is based primarily on metformins glucose-lowering effects, relatively low cost, and generally low level of side effects, including the absence of weight gain .
Metformins first-line position was strengthened by the United Kingdom Prospective Diabetes Study observation that the metformin-treated group had risk reductions of 32% for any diabetes-related endpoint, 42% for diabetes-related death , and 36% for all-cause mortality compared with the control group. The UKPDS demonstrated that metformin is as effective as sulfonylurea in controlling blood glucose levels of obese patients with type 2 diabetes mellitus . Metformin has been also been shown to be effective in normal weight patients .

Metformin Interactions: What Should I Avoid While Taking Metformin
When taken at the same time, some drugs may interfere with metformin. Make sure your healthcare team is aware of any medications that you take before you start on metformin, especially certain types of diuretics and antibiotics. Remember, insulin and insulin releasing medications can increase your risk of hypoglycemia, so it is particularly important to carefully monitor your glucose levels.
You should also avoid drinking excessive amounts of alcohol while taking metformin aim for no more than one glass per day for women, and two per day for men. Alcohol can contribute to lactic acidosis.

What Are The Most Common Side Effects Of Metformin
Metformin does cause side effects in some people, but many of these are mild, and are associated with taking the medicine for the first time. Nausea and gastric distress such as stomach pain, gas, bloating, and diarrhea are somewhat common among people starting up on metformin.
For some people, taking large doses of metformin right away causes gastric distress, so its common for doctors to start small and build the dosage up over time. Many people start with a small metformin dose 500 milligrams once a day and build up over a few weeks until the dosage reaches least 1,500 milligrams daily. This means theres less chance of getting an upset stomach from the medicine, but also means it may take a bit longer to experience the full benefit when getting started on metformin.
I experienced some mild side effects when I started taking metformin, and I found that the symptoms correlated with how many carbs I had in my diet. Once I dropped my carbs to 30-50 grams per day something that took me weeks to do any symptoms of gastric upset went away.
Asking your doctor for the extended-release version of metformin can keep these symptoms at bay, and so can tracking your diet.
Metformin And Heart Failure
The risk of developing cardiac heart failure in diabetic individuals nearly doubles as the population ages . DM and hyperglycemia are strongly implicated as a cause for the progression from asymptomatic left ventricular dysfunction to symptomatic HF, increased hospitalizations for HF, and an overall increased mortality risk in patients with chronic HF . Despite all its benefits, metformin is contraindicated in patients with heart failure due to the potential risk of developing lactic acidosis, a rare but potentially fatal metabolic condition resulting from severe tissue hypoperfusion . The US Food and Drug Administration removed the heart failure contraindication from the packaging of metformin although a strong warning for the cautious use of metformin in this population still exists .
Several retrospective studies in patients with CHF and diabetes reported lower risk of death from any cause , lower hospital readmissions for CHF , and hospitalizations for any cause . A recent review concluded that CHF could not be considered an absolute contraindication for metformin use and also suggest its protective effect in reducing the incidence of CHF and mortality in T2DM . This protective effect may due to AMPK activation and decrease in cardiac fibrosis .

Does Metformin Cause Cancer
In 2019 the FDA investigated whether some forms of metformin contain high levels of a carcinogenic chemical called N-nitrosodimethylamine . In 2020, the FDA recommended the recall of several versions of extended-release metformin, and more than a dozen companies have since voluntarily recalled certain lots of the medication. While low levels of NDMA are commonly found in foods and drinking water, high levels of the substance are toxic and can cause cancer.
You can check to see if your metformin has been recalled here. For people taking extended-release metformin, the FDA recommends that you continue to take your medication until you talk to your healthcare professional.
Data Extraction And Risk Of Bias Assessment
Two authors independently extracted data from the included trials using standard forms, and assessed the risk of bias according to the Cochrane Collaboration.14 They assessed the following risk of bias domains: generation of the allocation sequence, allocation concealment, blinding of investigators and participants, blinding of outcome assessors, incomplete outcome data, selective outcome reporting, and other sources of bias.15 Each item was classified as low, unclear, or high risk of bias.15 The involvement of a third author resolved any discrepancies. Data extraction and assessment for all relevant non-English articles were obtained through translated texts.
The primary outcomes in this review were all cause mortality and cardiovascular mortality.15 The secondary outcomes were macrovascular and microvascular diseases assessed as composite outcomes and in separate adverse events, cancer, quality of life, costs of intervention, insulin dose, glycaemic control, weight, and blood pressure.15

Mean GHb levels decreased 0.6% point more in the metformin than in the placebo group . The difference in GHb levels between the metformin and placebo groups was similar in each of the three centers . The daily dose of insulin increased 1.4 IU in the placebo group and decreased 7.2 IU in the metformin group .
Ask Questions Seek Answers For More Personalized Care
First and foremost, you should know what diabetes-related complications you may be facing as these risks will determine which medications are best for you.
In addition, when doctors consider which medications to prescribe to youfrom among the standard and newer types of drugsthey should also consider your personal preferences, such as the timing of the medications in coordination with drugs you are already taking and the formulation of the drug .
They will also consider any drug intolerances, your overall health status, and any risk factors for developing diabetes-related complications.
Most importantly, doctors need to be sure that the benefits of taking a particular medication outweigh any harm to the patient from possible risk of side effects, and lastly, they should consider the affordability of any medication they are going to add to your treatment plan.
If the cost is too high or you cannot afford the co-pay, there is no reason to write you a prescription for a drug you wont be taking. Instead, the doctor must be sure that you are willing and able to take the medications as recommended.
Although doctors are advised to consider the practice guidelines of care developed by professional organizations, they must also consider how these treatment recommendations may affect you, and then tailor the general treatment to adjust for your specific needs.5
