Background:
Hydrocortisone-d4is intended for use as an internal standard for the quantification of hydrocortisone/cortisol by GC- or LC-MS. Cortisol, known as hydrocortisone when used as a therapeutic, is a glucocorticoid produced by the adrenal cortex in response to adrenocorticotropic hormone (ACTH).1,2It is an agonist at the mineralocorticoid receptor (MR) and the glucocorticoid receptor (GR), with an approximately 6- to 10-fold greater affinity for MR. Cortisol production is increased during periods of stress, and it is a major effector molecule in the hypothalamic-pituitary-adrenal axis (HPA) stress response.2Cortisol levels increase with age and are often elevated in major depressive disorder, certain forms of hypertension, and Parkinson's disease.3,4,5
