Repaglinide
Uses of Repaglinide
- Repaglinide is an antidiabetic medicine used to manage blood sugar levels in adults with type 2 diabetes.
Repaglinide is commonly used for:
1. Type 2 diabetes management: Helps lower blood sugar levels, particularly the rise in blood glucose that occurs after meals, by stimulating the pancreas to release insulin.
2. Postprandial (after-meal) blood sugar control: Specifically targets blood sugar spikes following food intake, as it is taken shortly before each meal.
3. Combination therapy: Used alongside diet, exercise, and sometimes other antidiabetic medicines such as Metformin to improve overall blood sugar control.- Repaglinide is typically taken before each main meal and should be skipped if a meal is skipped, as its action is closely tied to food intake.

How Repaglinide works
- Repaglinide is an antidiabetic medicine belonging to the meglitinide class, which works by stimulating the pancreas to release insulin in response to meals.
- It works by binding to and closing specific potassium channels (ATP-dependent potassium channels) on the surface of pancreatic beta cells - the cells responsible for producing and releasing insulin.
- When these potassium channels close, it causes the beta cell membrane to depolarise (change its electrical charge), which in turn opens calcium channels, allowing calcium to flow into the cell. This calcium influx triggers the beta cells to release stored insulin into the bloodstream.
- A key feature of Repaglinide is that its action is glucose-dependent: when blood glucose levels are higher, such as after a meal, more insulin is released. This insulin then helps cells throughout the body take up glucose from the blood and reduces the liver's own glucose production, lowering overall blood sugar levels.
- Because Repaglinide has a fast onset and short duration of action, it is taken shortly before meals to specifically target the after-meal rise in blood sugar.
