At a Glance

A synthetic ACTH(1-24) fragment used as the diagnostic agent cosyntropin to help evaluate adrenal cortisol response.

Plain English

Cosyntropin is the diagnostic ACTH(1-24) product used to help clinicians assess adrenal response. It is not the same product or evidence base as full-length ACTH(1-39) preparations.

Overview

ACTH 1-24, also called cosyntropin or tetracosactide, is the N-terminal 24-amino-acid fragment of ACTH. This record is limited to CORTROSYN cosyntropin, a diagnostic agent used in screening and evaluation of adrenocortical insufficiency in adults and pediatric patients. It is not a record for full-length ACTH(1-39), HP Acthar Gel, or their therapeutic indications.

Research Summary

CORTROSYN labeling supports cosyntropin (ACTH 1-24) as a diagnostic agent for screening and evaluation of adrenocortical insufficiency, with product-specific IV or IM administration. This evidence framing does not extend to therapeutic use of full-length ACTH(1-39), HP Acthar Gel, or ACTH(1-39)-specific indications.
