MAXIDEX vs SERVISONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
MAXIDEX (dexamethasone) is a potent glucocorticoid that binds to the glucocorticoid receptor (GR), leading to modulation of gene expression and inhibition of inflammatory mediators such as prostaglandins and leukotrienes. It suppresses immune response through inhibition of cytokine production (e.g., IL-1, IL-2, TNF-alpha) and reduces vasodilation and vascular permeability.
SERVISONE is a corticosteroid that exerts anti-inflammatory and immunosuppressive effects by binding to glucocorticoid receptors, modulating gene transcription, and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
One to two drops of the 0.1% ophthalmic suspension into the conjunctival sac every hour during the day and every two hours at night initially; after improvement, reduce to one drop every four hours, then one drop three to four times daily.
10-20 mg orally once daily in the morning; higher doses up to 40 mg daily for severe cases.

Terminal elimination half-life is approximately 2-3 hours for dexamethasone; in ocular tissues, half-life may be prolonged due to local retention, but systemic half-life is short with minimal accumulation.
Terminal elimination half-life is 3-4 hours. Clinically, this supports twice-daily dosing for sustained effect.
Primarily hepatic metabolism via CYP3A4; renal excretion of metabolites accounts for <15% unchanged drug; biliary/fecal elimination of metabolites predominates.
Renal (70-80% as metabolites, 5-10% unchanged); fecal/biliary (15-20%)
