BRYHALI vs CORTALONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BRYHALI (halobetasol propionate) is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive effects through the induction of phospholipase A2 inhibitory proteins (lipocortins), which inhibit the release of arachidonic acid and subsequent prostaglandin and leukotriene synthesis.
Cortisone is a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to suppress inflammation and immune response, and regulate metabolism.
Apply a thin layer to affected areas once daily. For psoriasis, maximum weekly dose of 60 g. Do not exceed 100 g per week. For atopic dermatitis, do not exceed 60 g per week.
10-40 mg orally once daily in the morning; for acute exacerbations, up to 60 mg/day divided into 2-4 doses.

Terminal elimination half-life is 1-4 hours in fast acetylators and 2-5 hours in slow acetylators (AUC significantly higher in slow acetylators). This influences dosing frequency; slow acetylators may require lower doses to avoid accumulation and toxicity.
Terminal elimination half-life is 3-5 hours in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment (CrCl <30 mL/min).
Primarily hepatic metabolism followed by renal excretion of metabolites. Unchanged BRYHALI (isoniazid) is excreted renally: 50-70% as parent drug and metabolites (acetylisoniazid, isonicotinic acid) within 24 hours. Less than 5% excreted unchanged in feces.
Primarily renal (60-70% as unchanged drug), with 10-20% biliary/fecal.
