Computed with the same four public criteria as every profile. The human-evidence grade on an indexed profile is set automatically and may change when it is hand-reviewed. It is not a safety score, not a purity rating, and not medical advice, and not a claim that this compound treats, cures, or prevents any condition.

What it is

Corticotropin, also called ACTH, is a peptide hormone normally made by the pituitary gland that signals the adrenal glands to release cortisol and related steroids. Prescription forms such as Acthar and Purified Cortrophin Gel are long-acting repository preparations, and ACTH is also thought to act on melanocortin receptors elsewhere in the body.

What the evidence shows

Automatic summaryHuman trials

Corticotropin gel products are FDA-approved prescription drugs, approved for conditions including infantile spasms (Acthar) and certain flares of multiple sclerosis, rheumatic, and other inflammatory disorders, with over 200 registered human trials. For several of its older labeled uses, modern comparative evidence against standard corticosteroids is limited and debated.
