LIBRAX® combines in a single capsule formulation the antianxiety action of chlordiazepoxide hydrochloride and the anticholinergic/spasmolytic effects of clidinium bromide. Chlordiazepoxide hydrochloride is a versatile, therapeutic agent of proven value for the relief of anxiety and tension. It is indicated when anxiety, tension or apprehension are significant components of the clinical profile. It is among the safer of the effective psychopharmacologic compounds. Clidinium bromide is a synthetic anticholinergic agent which has been shown in experimental and clinical studies to have a pronounced antispasmodic and antisecretory effect on the gastrointestinal tract. It inhibits muscarinic actions of acetylcholine at postganglionic parasympathetic neuroeffector sites. LIBRAX® is indicated to control emotional and somatic factors in gastrointestinal disorders. It may also be used as adjunctive therapy in the treatment of peptic ulcer and in the treatment of the irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and acute enterocolitis.

Sample Use Guides

In Vivo Use Guide

Because of the varied individual responses to tranquilizers and anticholinergics, the optimum dosage of LIBRAX® varies with the diagnosis and response of the individual patient. The dosage, therefore, should be individualized for maximum beneficial effects. The usual maintenance dose is 1 or 2 capsules, 3 or 4 times a day administered before meals and at bedtime.

Route of Administration: Oral

In Vitro Use Guide

Binding of [3H]-NMeQNB (clidinium) to crude membranes of freshly isolated bovine aortic endothelial cells was atropine-displaceable and of high affinity (Kd = 0.48 nM) to a single class of sites (maximum binding capacity: 14 +/- 3 fmol/mg protein). Stereospecificity of the binding sites was demonstrated in experiments in which [3H]-NMeQNB binding was inhibited by dexetimide in the nanomolar range (Ki = 0.63 nM) and by levetimide, its stereoisomer in the micromolar range (Ki = 3.2 uM) (selectivity factor: approximately 5000). Binding of [3H]-NMeQNB to freshly harvested intact cells was also atropine-displaceable, stereospecific (selectivity factor: approximately 3500) and of high affinity (Kd = 0.35 nM). The maximum binding capacity (9 +/- 2 fmol/mg total cell protein) was comparable to that of membranes and corresponded to approximately 900 binding sites per endothelial cell.
