CARMOL HC vs CORDRAN N
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Carmol HC is a combination of urea (a keratolytic) and hydrocortisone (a corticosteroid). Urea softens and dissolves the intercellular matrix of the stratum corneum, promoting desquamation and enhancing penetration of hydrocortisone. Hydrocortisone suppresses inflammation by induction of phospholipase A2 inhibitory proteins, collectively called lipocortins, which control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes.
Cordran N contains flurandrenolide, a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive actions by inducing phospholipase A2 inhibitory proteins (lipocortins) and modulating gene expression; neomycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit.
Apply a thin film to affected area twice daily; topical, not for ophthalmic or oral use.
Apply sparingly to affected area 2-3 times daily. Use for no longer than 2 weeks.

1-2 hours (hydrocortisone acetate); clinical effects persist longer due to local anti-inflammatory action; tissue half-life not well defined.
Approximately 1-2 hours. Short half-life consistent with topical use; systemic exposure minimal with proper application.
Primarily renal excretion of metabolites (40-60%) as glucuronide and sulfate conjugates; <10% unchanged; biliary/fecal elimination accounts for <20%.
Primarily renal (biliary/fecal minimal). Unchanged drug and glucuronide metabolites excreted in urine.
