Abstract

Oral prednisone (1)might be a convenient, inexpensive alternative to IV methylprednisolone (IVMP) if the bioequivalent dose was known. We compared the total amount of steroid absorbed after 1250 mg oral prednisone vs 1 gram IVMP in 16 patients with multiple sclerosis (MS). At 24 hours, the mean area under the concentration-time curve (AUC), the main component of bioavailability, did not differ between groups (p = 0.122). This suggests that the amount of absorbed corticosteroid is similar after either steroid at these doses.
