This document compares the potency and properties of various glucocorticosteroids. It lists cortisone, hydrocortisone, prednisone, prednisolone, and methylprednisolone as intermediate acting steroids with anti-inflammatory potencies ranging from 0.8 to 5 times that of hydrocortisone and sodium retaining effects from 0.6 to 1. Dexamethasone is categorized as long acting with the highest potency of 25 times hydrocortisone and lowest sodium retaining effect of 0.75. The document also notes that physiological cortisol secretion is equivalent to 7.5mg of prednisone per day.
