Chlordiazepoxide is a benzodiazepine that enhances GABA-A receptor activity, increasing chloride ion conductance and causing CNS depression. Clidinium is an anticholinergic that blocks muscarinic acetylcholine receptors, reducing gastrointestinal motility and secretions.
100 mg orally once daily with or without food.
1-2 capsules orally 3-4 times daily (each capsule contains chlordiazepoxide 5 mg and clidinium 2.5 mg).

Terminal elimination half-life is 12–15 hours in patients with normal renal function; prolonged to 24–40 hours in moderate to severe renal impairment (CrCl <30 mL/min).
Chlordiazepoxide: 5-30 hours (terminal half-life; increases with age, liver disease; active metabolite desmethyldiazepam has half-life 30-200 hours). Clidinium: 3-4 hours.
Approximately 70% of the dose is excreted renally as unchanged drug, 20% via biliary/fecal elimination, and 10% as oxidative metabolites in urine.
Chlordiazepoxide (CDX): Renal (1-2% unchanged, 4-6% as metabolites), biliary/fecal (minor). Clidinium bromide: Fecal (50-60% as unchanged drug), renal (40-50% as metabolites and unchanged).
