Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inverse agonist of peripheral histamine H1 receptors, inhibiting histamine release from mast cells and basophils.
Hydroxyzine pamoate is a piperazine derivative with antihistamine (H1 receptor antagonist) and anticholinergic properties. It also has sedative, anxiolytic, and antiemetic effects, likely mediated through suppression of subcortical regions of the central nervous system.
10 mg orally once daily
Oral: 50-100 mg every 6 hours as needed for pruritus or anxiety; maximum 600 mg/day. IM: 25-100 mg every 4-6 hours as needed.

Terminal elimination half-life of loratadine is 8.4 hours (range 3–20 hours); for its active metabolite descarboethoxyloratadine, it is 24.9 hours (range 8.8–45 hours). Clinical context: Steady-state concentrations are achieved by day 5.
Terminal elimination half-life is approximately 20 hours (range 14-25 hours) in adults; may be prolonged in elderly or hepatic impairment.
Primarily renal (approximately 40% as metabolites, <1% as unchanged drug) and fecal (approximately 40% as metabolites).
Primarily hepatic metabolism; <1% excreted unchanged in urine. Biliary/fecal elimination accounts for approximately 50% of metabolites.
