ANUSOL HC vs CARMOL HC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone, a corticosteroid, binds to glucocorticoid receptors, inhibiting phospholipase A2 activity and reducing prostaglandin and leukotriene synthesis. It also suppresses cytokine production and inflammatory cell migration, leading to decreased edema, erythema, and pruritus in anorectal tissues.
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.
Apply a thin layer to the affected area rectally 2 to 4 times daily, or after each bowel movement, for up to 7 days. Each application should not exceed 1 gram.
Apply a thin film to affected area twice daily; topical, not for ophthalmic or oral use.

Terminal elimination half-life of hydrocortisone is approximately 1.5-2 hours (range 1-3 h) in adults; clinical effect outlasts half-life due to intracellular receptor-mediated action.
1-2 hours (hydrocortisone acetate); clinical effects persist longer due to local anti-inflammatory action; tissue half-life not well defined.
Renal (primarily as metabolites) >80%; fecal ~15%; <2% unchanged in urine due to extensive hepatic metabolism. Biliary excretion is negligible.
Primarily renal excretion of metabolites (40-60%) as glucuronide and sulfate conjugates; <10% unchanged; biliary/fecal elimination accounts for <20%.
