COLOCORT vs VALISONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Colocort (hydrocortisone acetate) is a corticosteroid that binds to the glucocorticoid receptor, leading to inhibition of inflammatory mediators such as prostaglandins and leukotrienes, and suppression of immune responses.
Betamethasone valerate is a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), which control the release of arachidonic acid from membrane phospholipids, thereby inhibiting prostaglandin and leukotriene synthesis. It has anti-inflammatory, antipruritic, and vasoconstrictive effects.
10 mg rectally administered once daily, preferably at bedtime, as a retention enema.
Topical: Apply a thin layer to affected skin once or twice daily. Maximum duration: 2 weeks.

Terminal elimination half-life: 2.5–3.5 hours (mean ~3 hours). No active metabolites, so duration of action correlates with half-life.
Approximately 1.7 hours after topical application; systemic half-life is short due to rapid metabolism.
Renal: ~30% as metabolites; fecal/biliary: ~20% as metabolites; remainder metabolized with minimal unchanged drug excreted.
Renal (primarily as metabolites, <5% unchanged); biliary/fecal elimination accounts for <10%.
