Intramuscularly administered methylprednisolone sodium phosphate (Medrol Stabisol) in single doses of 40, 80, or 160 mg (methylprednisolone equivalents) had a similar effect as the same doses of methylprednisolone sodium succinate (Solu-Medrol) with regard to eosinophil suppression, elevation of glucose, white blood count differential shifts (lympholytic effect), urinary excretion of sodium and potassium, and localized (pain) and systemic side effects. The average plasma methylprednisolone concentration was approximately 20% higher after the intramuscular administration of methylprednisolone sodium phosphate than after methylprednisolone sodium succinate. The differences in plasma methylprednisolone levels produced by the two esters suggest that either hydrolysis of the succinate ester occurs more slowly or the succinate ester distributes more extensively. This difference in plasma level, however, is not reflected in any other pharmacologic evaluation of the two esters, e.g., both eosinophil depression and hyperglycemic response were identical. No clinically significant changes in the vital signs, standard hematology, and clinical chemistry parameters evaluated were noted after 21 successive doses (q.i.d. for five days with one dose in the morning of day 6) of 80 mg methylprednisolone sodium phosphate. An increase was noted in the systolic blood pressure from a pretreatment mean of 113 mm Hg to a posttreatment mean of 123 mm Hg and an increase in the body weight from a pretreatment mean of 177 pounds to a posttreatment mean of 183 pounds. No signs of adrenal suppression were found as judged by plasma cortisol and ACTH levels. Six (6/12) subjects of the methylprednisolone sodium phosphate group, one (1/12) subject of the vehicle group, and one (1/12) subject of the placebo (sterile saline) group reported the following systemic side effects: gas in stomach, headaches, anorectal itching, and dryness of itching of the skin. No trend was observed for any side effect reported. In these double-blind, randomized studies, single (40, 80, and 160 mg) and multiple (80 mg) intramuscular doses of methylprednisolone sodium phosphate were tolerated in healthy volunteers as well as the same doses of methylprednisolone sodium succinate and similar volumes of vehicle or placebo.
