From the Guidelines
The recommended treatment for type 2 diabetes involves initiating lifestyle modifications and metformin as the first-line medication, with a starting dose of 500mg once daily and gradual increase to 1000mg twice daily as tolerated, based on the most recent and highest quality evidence from 2024 1.
Initial Management
Initial management should focus on:
- Diet changes, reducing refined carbohydrates and increasing fiber intake
- Regular physical activity, aiming for 150 minutes of moderate exercise weekly
- Weight loss of 5-10% if overweight
Medication Therapy
Metformin is the preferred initial glucose-lowering medication for most people with type 2 diabetes, due to its efficacy, safety, tolerability, low cost, and extensive clinical experience 1. If glycemic targets (typically HbA1c <7%) aren't achieved with metformin alone, additional medications may be added based on individual factors, such as:
- SGLT-2 inhibitors (like empagliflozin 10-25mg daily)
- GLP-1 receptor agonists (such as semaglutide 0.25-1mg weekly injection)
- DPP-4 inhibitors (sitagliptin 100mg daily)
- Sulfonylureas
- Insulin therapy for more advanced cases
Personalized Treatment
Treatment should be personalized considering:
- Cardiovascular risk
- Kidney function
- Hypoglycemia risk
- Cost
- Patient preferences Regular monitoring of blood glucose levels, quarterly or biannual HbA1c testing, and annual screening for complications are essential components of diabetes management, as recommended by the most recent guidelines 1. Key considerations in treatment decisions include a person-centered shared decision-making approach, addressing both glycemic and weight goals, and considering the effects on cardiovascular and renal comorbidities, as well as the risk of hypoglycemia and individual preferences 1.
From the FDA Drug Label
In a randomized, controlled clinical study (Study E) (n=570), LANTUS was evaluated for 52 weeks in combination with oral anti-diabetic medications (a sulfonylurea, metformin, acarbose, or combinations of these drugs) LANTUS administered once daily at bedtime was as effective as NPH insulin administered once daily at bedtime in reducing HbA1c and fasting glucose (Table 10). In a randomized, controlled clinical study (Study F), in patients with type 2 diabetes not using oral anti-diabetic medications (n=518), a basal-bolus regimen of LANTUS once daily at bedtime or NPH insulin administered once or twice daily was evaluated for 28 weeks. 5 mg, 15 mg, 30 mg, or 45 mg of pioglitazone hydrochloride, or placebo once daily. Therapy with any previous antidiabetic agent was discontinued eight weeks prior to the double-blind period Treatment with 15 mg, 30 mg, and 45 mg of pioglitazone hydrochloride produced statistically significant improvements in HbA1c and fasting plasma glucose (FPG) at endpoint compared to placebo
The recommended treatment for type 2 diabetes includes:
- LANTUS (glargine): administered once daily at bedtime, in combination with oral anti-diabetic medications or as a basal-bolus regimen 2
- Pioglitazone: 15 mg, 30 mg, or 45 mg once daily, as monotherapy or in combination with other antidiabetic agents 3 Key points:
- LANTUS and pioglitazone have been shown to be effective in reducing HbA1c and fasting glucose in patients with type 2 diabetes
- The choice of treatment should be individualized based on patient-specific factors, such as medical history, current medications, and lifestyle 2 3
From the Research
Type 2 Diabetes Treatment
The recommended treatment for type 2 diabetes involves a combination of lifestyle modifications and pharmacological interventions.
- Metformin as First-Line Treatment: Metformin is widely recommended as the first-line oral medication for glycemic control in patients with type 2 diabetes 4.
- Dual Therapy: For patients who do not achieve adequate glycemic control with metformin alone, dual therapy with the addition of another agent such as a sodium glucose co-transporter 2 inhibitor (SGLT-2) may be considered 5.
- Combination Therapy: Combination therapy with metformin and other agents such as sitagliptin, sulfonylureas, or thiazolidinediones may also be effective in achieving glycemic control 6, 7.
- Insulin Therapy: Insulin therapy may be considered for patients with severe hyperglycemia or those who have not responded to other treatments, although recent studies suggest that glucagon-like peptide-1 (GLP-1) receptor agonists may offer superior benefits in some cases 8.
Treatment Goals
The primary goal of type 2 diabetes treatment is to achieve and maintain adequate glycemic control, as measured by hemoglobin A1c (HbA1c) levels.
- HbA1c Targets: The American Association of Clinical Endocrinologists and the American Diabetes Association recommend HbA1c targets of ≤6.5% or ≤7%, respectively, although individualized targets may be appropriate for some patients.
- Weight Management: Weight management is also an important aspect of type 2 diabetes treatment, as many patients with type 2 diabetes are overweight or obese.
Emerging Therapies
Newer therapies, such as SGLT-2 inhibitors and GLP-1 receptor agonists, offer promising alternatives for the treatment of type 2 diabetes.
- SGLT-2 Inhibitors: SGLT-2 inhibitors have been shown to be effective in reducing HbA1c levels and promoting weight loss 5.
- GLP-1 Receptor Agonists: GLP-1 receptor agonists have been shown to offer superior benefits in terms of HbA1c reduction and weight loss compared to insulin therapy in some cases 8.
