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.
Selectively inhibits type 5 phosphodiesterase (PDE5), enhancing cyclic guanosine monophosphate (cGMP) accumulation, leading to smooth muscle relaxation and vasodilation in the corpus cavernosum.
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 to 2 tablets (10-20 mg) orally once daily, preferably in the morning.

3.5 hours (terminal); prolonged to 8-12 hours in renal impairment.
Terminal elimination half-life is 12-15 hours; clinically, this supports once-daily dosing with steady state achieved in 3-5 days.
Renal: 90% unchanged; biliary/fecal: 10% as metabolites.
Primarily renal excretion of unchanged drug (approx. 70-80%) with the remainder as inactive metabolites (10-15% fecal, 5-10% biliary).
