Research Overview
P11-4
P11-4 has been studied for its ability to penetrate initial carious lesions and self-assemble into a fibrillar matrix that nucleates hydroxyapatite. Human and preclinical studies support its role in non-invasive enamel repair.
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.
