COLOCORT vs DECADRON W/ XYLOCAINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colocort (hydrocortisone acetate) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, and suppression of immune responses.
Dexamethasone is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation and immune response. Lidocaine is a sodium channel blocker that stabilizes neuronal membranes, inhibiting nerve impulse initiation and conduction, producing local anesthesia.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
Not a standard pre-mixed combination; individual components dosed separately. Dexamethasone: 0.5-9 mg/day oral/IV divided every 6-12h. Lidocaine: 1-5 mg/kg IV bolus (max 300 mg), then 1-4 mg/min IV infusion; or local infiltration up to 4.5 mg/kg (max 300 mg) with epinephrine.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
Dexamethasone: 3-4 hours (short-acting steroid). Lidocaine: 1.5-2 hours (prolonged in heart failure/hepatic disease).
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Dexamethasone: Renal (~65% as metabolites, <10% unchanged); Biliary/Fecal (<35%). Lidocaine: Hepatic metabolism to MEGX; Renal (<10% unchanged).
