Research Overview

Insulin Degludec

Studies highlight prolonged action and lower glycemic variability compared with many other basal insulins. It is frequently used in research on ultra-long basal coverage and hypoglycemia reduction.

Insulin Lispro

Clinical studies show faster onset and shorter duration than regular insulin, improving post-meal glucose control. It is a standard comparator in diabetes pharmacology and closed-loop insulin-delivery research.
