Diabetes: Management and Pharmacotherapy01:15

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...
Insulin: Dosing Regimen and Adverse Effects01:16

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 Glitazones01:26

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...
Glucagon-like Receptor Agonists01:24

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...
Oral Hypoglycemic Agents: Glinides01:06

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...
Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Summary

Adding newer antidiabetes medications like GLP-1 receptor agonists, DPP-4 inhibitors, and SGLT2 inhibitors to insulin therapy can improve glycemic control in type 2 diabetes mellitus (T2DM) patients, while reducing weight gain and hypoglycemia risks.

Area of Science:

  • Endocrinology
  • Pharmacology
  • Metabolic Diseases

Background:

  • Type 2 diabetes mellitus (T2DM) often requires escalating treatment complexity.
  • Insulin therapy is effective for hyperglycemia but carries risks of weight gain and hypoglycemia.
  • Combining insulin with other agents can enhance glycemic control and mitigate insulin-related adverse effects.

Purpose of the Study:

  • To review the benefits and drawbacks of various antidiabetes agents as add-on therapy to insulin in T2DM.
  • To focus on newer drug classes for patients with suboptimal glycemic control on insulin.

Main Methods:

  • Conducted a PubMed search (2003-2013) for clinical and review articles on insulin combination therapy in T2DM.
  • Included search terms for specific drug classes like DPP-4 inhibitors, GLP-1 receptor agonists, and SGLT2 inhibitors.
  • Analyzed study design, clinical relevance, and effects on insulin combination therapy.

Main Results:

  • Traditional agents (sulfonylureas, thiazolidinediones) can worsen weight gain and hypoglycemia risks.
  • Newer agents (GLP-1 receptor agonists, DPP-4 inhibitors, SGLT2 inhibitors) improve glycemic control when added to insulin.
  • These newer agents have a low risk of hypoglycemia and promote weight reduction or neutrality.

Conclusions:

  • GLP-1 receptor agonists, DPP-4 inhibitors, and SGLT2 inhibitors are effective add-on therapies to insulin in T2DM.
  • These newer classes offer advantages over traditional agents due to lower risks of weight gain and hypoglycemia.
  • Consideration of these agents may lead to preferred insulin combination strategies.
