Glucocorticoids, naturally occurring and synthetic, are
adrenocortical steroids that are readily absorbed from the gastrointestinal
tract.
Naturally occurring glucocorticoids (hydrocortisone and cortisone), which also have salt-retaining properties, are used as replacement
therapy in adrenocortical deficiency states. Their synthetic analogs are
primarily used for their potent anti-inflammatory effects in disorders of many organ systems.
Glucocorticoids cause profound and varied metabolic effects.
In addition, they modify the body's immune responses to diverse stimuli.
Methylprednisolone is a potent anti-inflammatory steroid
with greater anti-inflammatory potency than prednisolone and even less tendency
than prednisolone to induce sodium and water retention.
Methylprednisolone sodium succinate has the same metabolic
and anti-inflammatory actions as methylprednisolone. When given parenterally
and in equimolar quantities, the two compounds are equivalent in biologic
activity. Following the intravenous injection of methylprednisolone sodium
succinate, demonstrable effects are evident within one hour and persist for a
variable period. Excretion of the administered dose is nearly complete within
12 hours. Thus, if constantly high blood levels are required, injections should
be made every 4 to 6 hours. This preparation is also rapidly absorbed when
administered intramuscularly and is excreted in a pattern similar to that
observed after intravenous injection.
