Research Overview

Ziconotide

Clinical studies and post-marketing data support ziconotide as an analgesic for severe chronic pain that does not respond to conventional therapy. Research focuses on balancing analgesic efficacy with neuropsychiatric tolerability and careful dose titration.

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.
