Patients with primary adrenal insufficiency require replacement of both mineralocorticoid, in the form of fludrocortisone, and glucocorticoid. All healthcare professionals should know how to manage patients with hypocortisolaemia, some of whom will be at risk of life threatening adrenal crises.1
In the United Kingdom, hydrocortisone is the most commonly prescribed glucocorticoid for replacement therapy in both primary and secondary hypocortisolaemia. Other glucocorticoids are more often used for other conditions. Dexamethasone is the most potent and is mainly used in intracranial and oncological conditions. Prednisolone is the standard treatment for most inflammatory conditions. Prednisone is also available as a delayed release preparation and is converted to active prednisolone by first pass metabolism in the liver.
In healthy humans, cortisol is secreted …
