CARMOL HC vs PSORCON
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.
Psorcon (diflorasone diacetate) is a corticosteroid that acts by inducing phospholipase A2 inhibitory proteins, collectively called lipocortins. It inhibits the release of arachidonic acid, thereby decreasing the formation of prostaglandins and leukotrienes, leading to anti-inflammatory, antipruritic, and vasoconstrictive effects.
Apply a thin film to affected area twice daily; topical, not for ophthalmic or oral use.
Apply a thin layer to affected skin twice daily. For scalp conditions, use lotion or shampoo as directed.

1-2 hours (hydrocortisone acetate); clinical effects persist longer due to local anti-inflammatory action; tissue half-life not well defined.
Terminal elimination half-life is approximately 2 hours (range 1.5–3 hours) after topical application; clinical significance: short half-life allows twice-daily dosing.
Primarily renal excretion of metabolites (40-60%) as glucuronide and sulfate conjugates; <10% unchanged; biliary/fecal elimination accounts for <20%.
Primarily renal (about 70% as unchanged drug and metabolites); biliary/fecal elimination of approximately 30%.
