PENECORT vs SYNALAR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
PENECORT is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression and suppressing inflammation, immune responses, and adrenal function.
Corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of phospholipase A2, decreased release of arachidonic acid, and reduced synthesis of prostaglandins and leukotrienes. This results in anti-inflammatory, antipruritic, and vasoconstrictive effects.
2.5-5 mg orally once daily; maximum 10 mg/day. Intramuscular: 20-40 mg every 2-4 weeks.
Apply a thin layer to affected area twice daily. Max 60 g/week.

Terminal elimination half-life: 3-4 hours in adults; prolonged in hepatic impairment (up to 8 hours).
Terminal elimination half-life: 1-2 hours (topical use); 3-4 hours (systemic absorption after topical application to large areas or occluded skin). Clinical context: short half-life allows once- or twice-daily dosing.
Renal: 60-70% as metabolites, 5-10% unchanged; Biliary/fecal: 20-30% as metabolites.
Renal: <1% as unchanged drug; biliary/fecal: minimal; primarily hepatic metabolism with metabolites excreted renally.
