Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methylprednisolone is a corticosteroid that inhibits phospholipase A2, reducing prostaglandin and leukotriene synthesis, and suppresses immune cell activity.
Competitively inhibits dihydropteroate synthase, blocking folic acid synthesis in susceptible bacteria.
Oral methotrexate 7.5-25 mg once weekly; subcutaneous methotrexate 7.5-25 mg once weekly; intravenous methotrexate 50-200 mg/m² every 2-3 weeks for oncology indications.
1-2 drops of 10-30% solution into the conjunctival sac every 2-3 hours initially, tapering as infection resolves. Ointment: 0.5-inch ribbon into conjunctival sac every 3-4 hours and at bedtime.
