Chlordiazepoxide-Clidinium
Librax is a brand-name combination medication containing chlordiazepoxide (a benzodiazepine anxiolytic) and clidinium (an anticholinergic agent). It is primarily prescribed for adults with functional gastrointestinal disorders, such as irritable bowel syndrome and peptic ulcers, where anxiety contributes to gastrointestinal symptoms like cramping and spasms. The dual-action formula addresses both the anxiety and the physical GI symptoms.
Librax combines an anti-anxiety medication with an antispasmodic to treat GI disorders where anxiety exacerbates symptoms.

Treats functional gastrointestinal conditions including irritable bowel syndrome, peptic ulcers, and gastric ulcers, particularly when anxiety accompanies GI symptoms such as abdominal cramps, spasms, and hypermotility.
Chlordiazepoxide enhances GABAergic neurotransmission to reduce anxiety, while clidinium blocks acetylcholine receptors in smooth muscle to decrease GI spasms, secretions, and motility.
Due to benzodiazepine content, carries risks of dependence, sedation, and withdrawal with prolonged use. Anticholinergic effects may cause dry mouth, constipation, and urinary retention. Should be used cautiously in elderly patients and avoided in narrow-angle glaucoma or urinary retention. Use is typically short-term; sudden discontinuation should be avoided.
