Introduction: This review focuses on currently available injectable combination therapies (ICTs) for managing diabetes.Areas covered: References were identified through searches of PubMed, Medline, and Embase for articles published till July 2019 using terms 'insulin' [MeSH Terms] OR 'glucagon like peptide 1 analogue' [All Fields] OR 'combination therapy' [All Fields] 'combination insulin therapy' [All Fields] OR 'combination GLP1 analogue therapy' [All Fields] OR 'premixed insulin' [All Fields].Expert opinion: Currently, there are nine types of ICTs for diabetes available. ICTs are classified on the basis of whether they are combinations of conventional human insulin, human insulin analogs, insulin coformulations, and insulin glucagon-like peptide-1 receptor agonists (GLP-1RA) and have a subtle difference in pharmacokinetic and pharmacodynamic properties. ICTs have been consistently demonstrated to play a major role in improving glycemic control. In a different meta-analysis involving patients assessed for glycemic control as the primary endpoint, no significant difference was noted with regard to HbA1c reduction, hypoglycemia, weight change, and daily insulin dose in patients on basal-bolus regimen, as compared to ICTs. All international guidelines recommend ICTs for treatment intensification.ICTs provide more flexibility to the treating doctor in fine-tuning the insulin/GLP-1RA regimen and have the advantages of reducing daily needle-prick count and better long-term compliance.

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: 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...

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...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

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...
