Prednisone and prednisolone have been found to be approximately four times as potent as cortisone and hydrocortisone in suppressing the inflammatory manifestations of rheumatoid arthritis.1 Since administration of these two synthetic steroids in moderate doses does not cause sodium retention or edema, they offer important advantages over previously used steroids. Cortisone and hydrocortisone have been employed in the treatment of systemic lupus erythematosus with considerable effectiveness in controlling many of the manifestations of this disease. These drugs, however, tend to intensify fluid retention and hypertension in patients with renal and cardiac involvement.
