KERLEDEX vs SYNALAR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Kerledex is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the CNS by inhibiting the reuptake of serotonin at the presynaptic neuronal membrane.
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.
Intravenous: 500 mg every 6 hours; Oral: 250 mg every 8 hours.
Apply a thin layer to affected area twice daily. Max 60 g/week.

Terminal half-life 12 hours (range 10–14) in normal renal function; extended to 30–50 hours in severe renal impairment (CrCl <30 mL/min); 6–8 hours in hepatic cirrhosis.
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: 70% unchanged; fecal/biliary: 20% as metabolites; 10% as minor metabolites. Total renal clearance 180 mL/min, active tubular secretion accounts for 60% of renal elimination.
Renal: <1% as unchanged drug; biliary/fecal: minimal; primarily hepatic metabolism with metabolites excreted renally.
