Summary
Using concentrated U200 insulin in automated insulin delivery (AID) systems can overcome cartridge volume limitations for people with high insulin needs. This approach supports wider AID adoption for managing diabetes effectively.
Area of Science:
- Endocrinology and Diabetes Technology
- Pharmacology
Background:
- Automated insulin delivery (AID) systems are standard for type 1 diabetes management.
- Limited insulin pump cartridge capacity poses a barrier for individuals with high total daily insulin (TDI) requirements.
- Increasing obesity and AID expansion to type 2 diabetes necessitate solutions for high TDI needs.
Purpose of the Study:
- To provide practical considerations for implementing U200 concentrated insulin in AID systems.
- To address barriers to AID use for individuals with high TDI.
- To guide clinicians on using U200 insulin with AID technology.
Main Methods:
- This perspective piece outlines practical implementation strategies.
- It covers candidate identification, pump filling considerations, and AID algorithm programming.
- Patient education and electronic health record documentation are also discussed.
Main Results:
- U200 insulin offers the same insulin dose in half the volume compared to U100 insulin.
- It has similar pharmacokinetic and pharmacodynamic profiles to U100 insulin.
- Off-label use of U200 insulin has facilitated AID use for high TDI needs.
Conclusions:
- U200 concentrated insulin is a viable strategy to overcome cartridge volume limitations in AID systems.
- Clinical implementation requires careful planning regarding patient selection, device programming, and education.
- Standardized approaches are recommended for successful integration into diabetes care.

01:27Insulin Formulations: Types and Delivery
632
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.

01:16Insulin: Dosing Regimen and Adverse Effects
665
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...

01:19One-Compartment Open Model for IV Bolus Administration: General Considerations
659
The one-compartment model is a pharmacokinetic tool that models the body as a single, uniform compartment, facilitating the understanding of drug distribution and elimination. This model is particularly beneficial for intravenous (IV) bolus administration, where the drug rapidly circulates throughout the body.
The drug's presence in the body is defined by an equation representing the difference between the rates of drug entry and exit. Key parameters—elimination rate constant,...

01:25Insulin: Biosynthesis, Chemistry, and Preparation
1.2K
The endoplasmic reticulum (ER) of pancreatic β-cells synthesizes preproinsulin, which consists of a signal peptide, A and B chains, and a C-peptide. Preproinsulin is then cleaved and folded into proinsulin, which translocates to the Golgi apparatus for sorting and packaging into secretory granules. In these granules, enzymatic clipping generates insulin and C-peptide.

01:25Routes of Drug Administration: Parenteral
2.8K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
225
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
