Abstract

Insights

Adding inhaled insulin (INH) to oral antihyperglycemic agents (OHAs) significantly improved glycemic control in type 2 diabetes patients. This injectable-free approach offers a new option for those not achieving targets with OHAs alone.

Area of Science:

  • Endocrinology
  • Metabolic Diseases
  • Pharmacology

Background:

  • Good glycemic control is crucial for managing type 2 diabetes mellitus (T2DM).
  • Many patients struggle to achieve target glycemic control with oral antihyperglycemic agents (OHAs) alone.
  • Suboptimal glycemic control necessitates exploring alternative or add-on therapies.

Purpose of the Study:

  • To evaluate the efficacy of adding preprandial inhaled insulin (INH) to existing OHA therapy.
  • To determine if INH can improve glycemic control in T2DM patients with suboptimal control.
  • To assess INH as an injectable-free treatment option.

Main Methods:

  • A 12-week, randomized, proof-of-concept study.
  • Sixty-eight T2DM patients with HbA1c 8.1%-11.9% were randomized.
  • Groups received either INH + OHA or OHA alone.

Main Results:

  • The INH + OHA group showed a significantly greater reduction in HbA1c (-2.3%) vs. OHA alone (-0.1%).
  • 34% of patients on INH + OHA achieved HbA1c <7%, compared to none in the OHA-only group.
  • Significant improvements in fasting and postprandial glucose were observed with INH + OHA.

Conclusions:

  • Preprandial INH addition to OHAs effectively improves glycemic control in T2DM.
  • This strategy offers an injectable-free alternative for patients with inadequately controlled T2DM.
  • INH demonstrates potential for enhancing diabetes management without injections.

Insulin: Dosing Regimen and Adverse Effects

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Oral Hypoglycemic Agents: Biguanides and Glitazones

Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood glucose levels...

Insulin Formulations: Types and Delivery

Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into rapid-acting...

Oral Hypoglycemic Agents: Glinides

Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively manages...

Diabetes: Management and Pharmacotherapy

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...
Oral Hypoglycemic Agents: Sulfonylureas01:17

Oral Hypoglycemic Agents: Sulfonylureas

Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide (Glucotrol),...
