CLARITIN-D vs CORPHEDRA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Loratadine is a long-acting tricyclic antihistamine with selective peripheral H1 receptor antagonism. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction.
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.
One tablet (5 mg loratadine/120 mg pseudoephedrine sulfate) orally every 12 hours; do not exceed 2 tablets in 24 hours.
10-20 mg orally every 8 hours as needed for nasal congestion.

Loratadine: 8-14 h (mean 11 h); desloratadine: 17-24 h (mean 21 h). Pseudoephedrine: 4-8 h (mean 6 h), prolonged in alkaline urine.
8-12 hours (terminal); clinical context: requires dosing every 12 hours; reduced clearance in elderly and renal impairment
Loratadine: 40% renal (metabolites), ~40% fecal; desloratadine: 33% renal, 66% fecal. Pseudoephedrine: 70-90% renal unchanged, 1-2% biliary.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
