Chlordiazepoxidum - General Information
An anxiolytic benzodiazepine derivative with anticonvulsant, sedative, and amnesic properties. It has also been used in the symptomatic treatment of alcohol withdrawal.
Pharmacology of Chlordiazepoxidum
Chlordiazepoxidum has antianxiety, sedative, appetite-stimulating and weak analgesic actions. The precise mechanism of action is not known. The drug blocks EEG arousal from stimulation of the brain stem reticular formation. The drug has been studied extensively in many species of animals and these studies are suggestive of action on the limbic system of the brain, which recent evidence indicates is involved in emotional responses. Hostile monkeys were made tame by oral drug doses which did not cause sedation. Chlordiazepoxidum revealed a "taming" action with the elimination of fear and aggression. The taming effect of chlordiazepoxide was further demonstrated in rats made vicious by lesions in the septal area of the brain. The drug dosage which effectively blocked the vicious reaction was well below the dose which caused sedation in these animals.
Chlordiazepoxidum for patients
To assure the safe and effective use of benzodiazepines, patients should be informed that, since benzodiazepines may produce psychological and physical dependence, it is advisable that they consult with their physician before either increasing the dose or abruptly discontinuing the drug.
Although clinical studies have not established a cause and effect relationship, physicians should be aware that variable effects an blood coagulation have been reported very rarely in patients receiving oral anticoagulants and chlordiazepoxide.
The concomitant use of alcohol or other central nervous system depressants may have an additive effect.
Chlordiazepoxide HCl Capsules are contraindicated in patients with known hypersensitivity to the drug.
Additional information about Chlordiazepoxidum
Chlordiazepoxidum Indication: For the management of anxiety disorders or for the short-term relief of symptoms of anxiety, withdrawal symptoms of acute alcoholism, and preoperative apprehension and anxiety.
Mechanism Of Action: Chlordiazepoxidum binds to stereospecific benzodiazepine (BZD) binding sites on GABA (A) receptor complexes at several sites within the central nervous system, including the limbic system and reticular formation. BZDs enhance GABA-mediated chloride influx through GABA receptor channels, causing membrane hyperpolarization. The net neuro-inhibitory effects result in the observed sedative, hypnotic, anxiolytic, and muscle relaxant properties.
