Clorazepate is a water-soluble benzodiazepine derivative effective in the treatment of anxiety. It has also muscle relaxant and anticonvulsant actions. Studies in healthy men have shown that clorazepate dipotassium has depressant effects on the central nervous system. clorazepate is a prodrug since orally administered it is rapidly decarboxylated to form nordiazepam, there is essentially no circulating parent drug. Nordiazepam positively modulates GABAA receptors to produce anxiolytic and anticonvulsant effects.

TRANXENE

Approved Use

TRANXENE is indicated for the management of anxiety disorders or for the short-term relief of the symptoms of anxiety. Anxiety or tension associated with the stress of everyday life usually does not require treatment with an anxiolytic. TRANXENE tablets are indicated as adjunctive therapy in the management of partial seizures. The effectiveness of TRANXENE tablets in long-term management of anxiety, that is, more than 4 months, has not been assessed by systematic clinical studies. Long-term studies in epileptic patients, however, have shown continued therapeutic activity. The physician should reassess periodically the usefulness of the drug for the individual patient. TRANXENE tablets are indicated for the symptomatic relief of acute alcohol withdrawal. CONTRAINDICATIONS TRANXENE tablets are contraindicated in patients with a known hypersensitivity to the drug and in those with acute narrow angle glaucoma.

Sample Use Guides

For the symptomatic relief of anxiety: TRANXENE T-TAB tablets are administered orally in divided doses. The usual daily dose is 30 mg. The dose should be adjusted gradually within the range of 15 to 60 mg daily in accordance with the response of the patient. In elderly or debilitated patients it is advisable to initiate treatment at a daily dose of 7.5 to 15 mg. TRANXENE tablets may also be administered in a single dose daily at bedtime; the recommended initial dose is 15 mg. After the initial dose, the response of the patient may require adjustment of subsequent dosage. Lower doses may be indicated in the elderly patient. Drowsiness may occur at the initiation of treatment and with dosage increment. As an Adjunct to Antiepileptic Drugs: In order to minimize drowsiness, the recommended initial dosages and dosage increments should not be exceeded. Adults: The maximum recommended initial dose in patients over 12 years old is 7.5 mg three times a day. Dosage should be increased by no more than 7.5 mg every week and should not exceed 90 mg/day. Children (9-12 years): The maximum recommended initial dose is 7.5 mg two times a day. Dosage should be increased by no more than 7.5 mg every week and should not exceed 60 mg/day
