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.
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.
