From the Guidelines

Type 2 diabetes mellitus management should prioritize an individualized approach, starting with lifestyle modifications and metformin as the first-line medication, with subsequent additions of SGLT-2 inhibitors, GLP-1 receptor agonists, or other agents based on patient-specific factors, as recommended by the most recent guidelines 1.

Key Considerations

  • Lifestyle modifications, including a balanced diet, regular physical activity (150 minutes of moderate exercise weekly), and weight loss of 5-10% if overweight, are essential for managing type 2 diabetes mellitus.
  • Metformin is the preferred initial pharmacologic agent, usually starting at 500 mg once or twice daily and gradually increasing to 1000 mg twice daily as tolerated, due to its efficacy, safety, and potential to reduce cardiovascular events and death 2, 3.
  • For patients not reaching glycemic targets (typically HbA1c <7%), additional medications may be added, considering individual factors such as cardiovascular disease, kidney disease, and patient preferences.
  • SGLT-2 inhibitors (empagliflozin, dapagliflozin) and GLP-1 receptor agonists (semaglutide, dulaglutide) are recommended for patients with established cardiovascular disease or kidney disease, as they have been shown to reduce all-cause mortality, major adverse cardiovascular events (MACE), and chronic kidney disease (CKD) progression 4.

Monitoring and Treatment Goals

  • Regular monitoring is essential, including HbA1c every 3-6 months, annual kidney function tests, and regular eye and foot examinations.
  • Treatment goals should consider the patient's age, comorbidities, hypoglycemia risk, and personal preferences, with a focus on achieving individualized glycemic and weight targets.
  • A person-centered shared decision-making approach should guide the choice of pharmacologic agents, taking into account the effects on cardiovascular and renal comorbidities, effectiveness, hypoglycemia risk, impact on weight, cost, and patient preferences 1.

From the FDA Drug Label

The management of antidiabetic therapy should be individualized. Ideally, the response to therapy should be evaluated using HbA1c which is a better indicator of long-term glycemic control than FPG alone. For patients who respond inadequately to the initial dose of ACTOS, the dose can be increased in increments up to 45 mg once daily. For patients not responding adequately to monotherapy, combination therapy should be considered The dose of ACTOS should not exceed 45 mg once daily in monotherapy or in combination with sulfonylurea, metformin, or insulin

Individual Treatment for Type 2 Diabetes Mellitus Management:

  • The management of antidiabetic therapy should be individualized.
  • The initial dose of pioglitazone (ACTOS) can be 15 mg or 30 mg once daily, and can be increased up to 45 mg once daily if necessary.
  • Combination therapy with other antidiabetic medications such as sulfonylurea, metformin, or insulin may be considered if monotherapy is not effective.
  • The dose of pioglitazone should not exceed 45 mg once daily in monotherapy or in combination with other medications.
  • HbA1c is a better indicator of long-term glycemic control than FPG alone, and should be used to evaluate the response to therapy 5.

From the Research

Individual Treatment for Type 2 Diabetes Mellitus

The management of type 2 diabetes mellitus (T2DM) involves various treatment strategies, with metformin being the most commonly recommended first-line therapy. The following points highlight the key aspects of individual treatment for T2DM:

  • Metformin is generally considered the first-line treatment for T2DM due to its efficacy, safety, and affordability 6, 7, 8.
  • However, metformin may not be suitable for all patients, particularly those with renal insufficiency or severe liver disease, and may cause gastrointestinal side effects in some individuals 6, 7.
  • Other treatment options, such as sulphonylureas, thiazolidinediones, and insulin, may be considered as add-on therapies or alternatives to metformin, but they also have their own set of limitations and potential side effects 6, 9.
  • Incretin-based therapies, including glucagon-like peptide-1 (GLP-1) receptor agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors, have shown promise in achieving glycaemic targets and providing cardiovascular benefits 6, 7, 10.
  • The choice of treatment should be individualized based on patient characteristics, such as disease severity, comorbidities, and risk factors, as well as considerations of cost and accessibility 8, 10.

Treatment Strategies and Options

The following treatment strategies and options are available for T2DM:

  • Monotherapy with metformin or other oral agents 6, 7.
  • Combination therapy with metformin and other oral agents or injectables, such as GLP-1 receptor agonists or insulin 6, 7, 9.
  • Early introduction of incretin-based therapies or other add-on agents to improve glycaemic control and reduce cardiovascular risk 6, 7, 10.
  • Consideration of newer glycemic-lowering medications with cardiovascular benefits, such as SGLT2 inhibitors, in high-risk patients 8, 10.
