Abbreviation for adrenocorticotropic hormone (also called corticotropin).
Synonym(s): corticotropin (3)

ACTH

(ā′sē′tē′āch′)
n.
A hormone produced by the anterior lobe of the pituitary gland that stimulates the secretion of cortisol and other hormones by the adrenal cortex. Also called adrenocorticotropin, corticotropin.

ACTH

A 39-amino acid hormone produced by the anterior pituitary gland, which regulates adrenocortical activity, stimulating release of cortisol, mineralocorticoids, and adrenal androgens; pituitary ACTH is regulated by corticotropin-releasing hormone (CRH).
Daily pattern ACTH levels vary over the space of a 24-hour day, peaking at 6–8 am and evening 6–11 pm; ACTH suppression or stimulation testing may be required to confirm the diagnosis of changes in adrenal function.
ACTH increased in Addison’s disease, congenital adrenal hyperplasia, Cushing disease, pituitary-dependent Cushing syndrome, ectopic ACTH-producing tumours, Nelson syndrome.
ACTH decreased in Secondary adrenocortical insufficiency, adrenal carcinoma, adenoma. 
Ref range < 120 pg/mL

ACTH

Adrenocorticotrophic hormone Endocrinology A 39-amino acid hormone produced by the anterior pituitary gland, which regulates adrenocortical activity, stimulating release of cortisol, mineralocorticoids, and adrenal androgens; pituitary ACTH is in turn regulated by corticotropin-releasing hormone–CRH; ACTH is ↑ in pituitary-dependent Cushing syndrome Daily pattern ACTH levels vary over the space of a 24 hr day, peaking at 6–8 am and 6–11 pm; ACTH suppression or stimulation testing may be necessary to confirm the diagnosis of changes in adrenal function; ACTH is ↑ in Addison's disease, congenital adrenal hyperplasia, Cushing's disease, ectopic ACTH-producing tumors, Nelson syndrome; ACTH is ↓ in 2º adrenocortical insufficiency, adrenal carcinoma, adenoma. See Cushing syndrome.

ACTH

Abbreviation for adrenocorticotropic hormone.

ACTH

Adrenocorticotropic HORMONE. This hormone is produced by the pituitary gland, on instructions from the hypothalamus (the part of the brain immediately above the gland) when a stressful situation arises. ACTH is carried by the blood to the adrenal glands and prompts them to secrete the hormone cortisol into the bloodstream. ACTH is sometimes used as medication.

Adrenocorticotropic hormone, a hormone normally produced by the pituitary gland, sometimes taken as a treatment for arthritis and other disorders.
