CORPHEDRA vs SUDAFED 12 HOUR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CorphEdra is a synthetic glucocorticoid that binds to the glucocorticoid receptor (GR), leading to transcriptional regulation of anti-inflammatory and immunosuppressive genes. It also activates the mineralocorticoid receptor (MR) with lower affinity, contributing to electrolyte and fluid balance effects.
Pseudoephedrine is a sympathomimetic amine that acts as an agonist at alpha-1 and alpha-2 adrenergic receptors, causing vasoconstriction of nasal mucosa and reducing nasal congestion.
10-20 mg orally every 8 hours as needed for nasal congestion.
120 mg orally every 12 hours, extended-release tablets. Maximum 240 mg per day.

8-12 hours (terminal); clinical context: requires dosing every 12 hours; reduced clearance in elderly and renal impairment
8-10 hours in adults with normal renal function; prolonged to 19-24 hours in renal impairment (CrCl <30 mL/min); shorter in children (3-4 hours)
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Renal: 74-95% as unchanged drug; 1-4% as active metabolite (norpsuedoephedrine); biliary/fecal: minimal (<1%)
