Decelerating gastric emptying: therapeutic possibilities in type 2 diabetes

Area of Science:

• Endocrinology
• Gastroenterology
• Metabolic Diseases

Background:

• A positive correlation exists between carbohydrate absorption, plasma glucose concentration, and gastric emptying rate.
• Clinical manipulation of gastric emptying may offer therapeutic potential for glycemic control.
• Cholecystokinin (CCK-8) delays gastric emptying in type 2 diabetes but requires intravenous administration.

Purpose of the Study:

• To explore therapeutic strategies for glycemic control in type 2 diabetes by manipulating gastric emptying.
• To investigate alternative administration routes for CCK-8 or agents that enhance its endogenous release.

Main Methods:

• Review of existing evidence on the relationship between gastric emptying and glucose metabolism.
• Discussion of potential therapeutic agents targeting CCK pathways.
• Consideration of different administration routes for CCK-based therapies.

Main Results:

• Cholecystokinin (CCK-8) effectively delays gastric emptying in individuals with type 2 diabetes.
• Intravenous administration of CCK-8 is a limitation; alternative routes like intramuscular injections, intranasal sprays, or oral CCK analogues are preferred.
• Oral administration of agents enhancing endogenous CCK release, such as POT II, is a potential therapeutic approach.

Conclusions:

• Modulating gastric emptying represents a viable strategy for managing type 2 diabetes.
• Enhancing endogenous cholecystokinin (CCK) release via oral administration offers a promising therapeutic avenue for type 2 diabetes treatment.
• Agents like POT II may be indicated for patients with recently diagnosed type 2 diabetes.
