What is the recommended dosage and administration of Admelog (insulin lispro) for patients with diabetes?

Admelog (Insulin Lispro) Dosage and Administration for Diabetes Patients

For patients with diabetes, Admelog (insulin lispro) should be dosed at 0.1-0.2 units/kg per meal or approximately 4 units per meal initially, with subsequent adjustments based on blood glucose monitoring. 1, 2

General Dosing Principles

Initial Dosing

• Type 1 Diabetes:

  • Total daily insulin: 0.4-1.0 units/kg/day 1
  • Typically 50% as basal insulin and 50% as prandial (mealtime) insulin 1, 2
  • Starting dose: approximately 0.5 units/kg/day for metabolically stable patients 1

• Type 2 Diabetes:

  • Higher doses often required (≥1 unit/kg) 1
  • Lower rates of hypoglycemia compared to type 1 diabetes 1
  • Can be used alone or in combination with oral agents 3

Administration Timing

• Administer 15-30 minutes before meals for optimal postprandial glucose control in hyperglycemic patients 4
• Can be administered immediately before meals, but pre-meal administration provides better postprandial control 5, 4

Dosage Adjustments

Prandial Insulin Titration

• Adjust doses based on:
  • Premeal blood glucose levels
  • Carbohydrate intake (carbohydrate counting)
  • Anticipated physical activity 1
  • Postprandial glucose monitoring (target <180 mg/dL) 2

Insulin-to-Carbohydrate Ratios

• Start with 1 unit of Admelog per 10-15g of carbohydrate 2
• Adjust based on postprandial glucose monitoring

Correction Doses

• Use the "1500 rule" to calculate correction doses:
  • Correction factor = 1500 ÷ Total daily insulin dose 2

Special Formulations

Concentrated Insulin

• Admelog is available as U-200 (200 units/mL) concentrated formulation 1
• Beneficial for patients requiring large doses of insulin
• Available only in prefilled pens to minimize dosing errors 1

Monitoring and Safety

Blood Glucose Monitoring

• Monitor blood glucose 1-2 hours after meals to assess postprandial control 2
• Measure HbA1c every 3 months to assess overall glycemic control 2

Hypoglycemia Prevention

• Proper injection technique is crucial to prevent variable absorption 1, 2
• Use the shortest needles available (4-mm pen or 6-mm syringe needles) 3
• Avoid intramuscular injections, especially with long-acting insulins 3
• Rotate injection sites to prevent lipohypertrophy 3

Clinical Pearls

• Admelog has a rapid onset (15-30 minutes), peak action at 1-3 hours, and duration of 3-5 hours 2
• Elderly patients may require lower doses and more frequent monitoring to reduce hypoglycemia risk 2
• Combining Admelog with metformin can result in decreased weight gain, lower insulin dose, and less hypoglycemia compared to insulin alone 3
• Studies show that rapid-acting insulin analogs like Admelog can improve HbA1c levels by 0.3-0.4% in type 1 diabetes and 1.5-2.5% in type 2 diabetes when properly dosed 6, 7

Common Pitfalls to Avoid

• Never abruptly discontinue oral medications when starting insulin therapy due to risk of rebound hyperglycemia 3
• Avoid confusing rapid-acting insulins with long-acting insulins to prevent dangerous dosing errors 2
• Don't use only rapid-acting insulin without basal insulin coverage, as this can result in periods of inadequate insulin coverage and hyperglycemia 2
• Avoid injecting into areas of lipohypertrophy as this distorts insulin absorption 3
