Research Overview

Cosyntropin

Cosyntropin is not a standard pain drug, but it appears in headache literature because ACTH analogs can help some patients with difficult migraine attacks. The analgesic rationale is partly tied to steroidogenic and anti-inflammatory effects.

hGHRH(1-40)OH

Human GHRF(1-40)OH has been studied to understand how truncation of the native hormone changes biological potency and half-life. It is a common research tool for mapping minimal active sequences within the GHRH family.
