From the Guidelines

For post-meal hyperglycemia, rapid-acting insulin analogs like insulin lispro (Humalog), insulin aspart (NovoLog), or insulin glulisine (Apidra) are the most effective medications, as they quickly enter the bloodstream to process carbohydrates from meals, mimicking normal pancreatic insulin secretion 1.

Key Considerations

  • These medications should be taken 15 minutes before meals, with dosing typically starting at 4-6 units and adjusted based on blood glucose monitoring.
  • The dose depends on carbohydrate intake, pre-meal glucose levels, and anticipated physical activity.
  • Alternatively, non-insulin options include GLP-1 receptor agonists such as semaglutide (Ozempic) or SGLT-2 inhibitors like empagliflozin (Jardiance), which can help reduce post-meal glucose spikes.

Mechanism of Action

  • Rapid-acting insulins work by quickly entering the bloodstream to process carbohydrates from meals, closely matching meal digestion timing.
  • They peak within 1-2 hours and have a duration of 3-4 hours.

Monitoring and Adjustment

  • Regular blood glucose monitoring 1-2 hours after meals is essential to evaluate effectiveness and adjust dosing appropriately.
  • Patients should also consider consistent carbohydrate counting and timing of meals to optimize medication effectiveness.

Additional Options

  • GLP-1 receptor agonists, such as semaglutide, have high glucose-lowering efficacy and minimal risk for hypoglycemia, but may increase the hypoglycemic potential of insulin and sulfonylureas when combined with those medications 1.

DOSAGE AND ADMINISTRATION There is no fixed dosage regimen for the management of diabetes mellitus with acarbose tablets or any other pharmacologic agent. During treatment initiation and dose titration (see below), one-hour postprandial plasma glucose may be used to determine the therapeutic response to acarbose tablets and identify the minimum effective dose for the patient.

Acarbose can be used to manage post meal hyperglycemia. The dosage of acarbose should be individualized and started at a low dose, with gradual dose escalation.

  • The recommended starting dosage is 25 mg given orally three times daily at the start of each main meal.
  • The dosage can be increased from 25 mg t.i.d. to 50 mg t.i.d. and some patients may benefit from further increasing the dosage to 100 mg t.i.d.
  • One-hour postprandial plasma glucose can be used to determine the therapeutic response to acarbose and identify the minimum effective dose for the patient 2.
  1. 2 Pharmacodynamics VICTOZA’s pharmacodynamic profile is consistent with its pharmacokinetic profile observed after single subcutaneous administration as VICTOZA lowered fasting, premeal and postprandial glucose throughout the day Compared to placebo, the postprandial plasma glucose AUC0-300min was 35% lower after VICTOZA 1.2 mg and 38% lower after VICTOZA 1.8 mg.

Liraglutide can also be used to manage post meal hyperglycemia.

  • Liraglutide lowers postprandial glucose by stimulating insulin secretion and lowering glucagon secretion in a glucose-dependent manner.
  • It also causes a delay of gastric emptying, reducing the rate at which postprandial glucose appears in the circulation 3.

From the Research

Medication Options for Post Meal Hyperglycemia

  • Repaglinide is a rapidly absorbed, short-acting insulin secretagogue that targets postprandial glucose excursions, making it a suitable option for managing post meal hyperglycemia 4, 5, 6.
  • The combination of repaglinide and metformin has been shown to improve glycemic control and is a rational second-line therapy for patients with type 2 diabetes who are not achieving adequate control with metformin alone 4.
  • Other medications that can help control postprandial hyperglycemia include alpha-glucosidase inhibitors, such as acarbose and miglitol, and rapid-acting insulin analogs 7.
  • Nateglinide is another short-acting insulin secretagogue that has been shown to be effective in controlling postprandial hyperglycemia, although it may have a shorter duration of action compared to glipizide 8.

Key Characteristics of Repaglinide

  • Repaglinide has a rapid onset of action and a short duration of action, making it suitable for controlling postprandial glucose excursions 5, 6.
  • It is generally well tolerated and has a tolerability profile similar to that of sulfonylurea drugs and nateglinide 6.
  • Repaglinide can be used as monotherapy or in combination with other oral antihyperglycemic drugs, and is at least as effective as other oral antihyperglycemic drugs at improving or maintaining glycemic control 6.

Clinical Evidence

  • Studies have consistently shown that repaglinide is effective in improving glycemic control and reducing postprandial glucose excursions in patients with type 2 diabetes 4, 5, 6.
  • The combination of repaglinide and metformin has been shown to be effective in improving glycemic control and is a rational second-line therapy for patients with type 2 diabetes who are not achieving adequate control with metformin alone 4.
  • Repaglinide has been compared to other short-acting insulin secretagogues, such as nateglinide, and has been shown to have a similar efficacy in controlling postprandial hyperglycemia 8.
