Oxazepam

Brand Names: Oxazepam

Drug Class: Benzodiazepine

Overview

DESCRIPTION Oxazepam, USP is the first of a chemical series of compounds known as the 3-hydroxybenzodiazepinones. A therapeutic agent providing versatility and flexibility in control of common emotional disturbances, this product exerts prompt action in a wide variety of disorders associated with anxiety, tension, agitation, and irritability, and anxiety associated with depression.

Mechanism of Action

CLINICAL PHARMACOLOGY Pharmacokinetic testing in 12 volunteers demonstrated that a single 30 mg dose of a capsule, tablet or suspension will result in an equivalent extent of absorption. For the capsule and tablet, peak plasma levels averaged 450 mg/mL and were observed to occur about 3 hours after dosing. The mean elimination half-life for oxazepam was approximately 8.2 hours (range 5.7 to 10.9 hours). This product has a single, major inactive metabolite in man, a glucuronide excreted in the urine. Age (less than 80 years old) does not appear to have a clinically significant effect on oxazepam kinetics.

Indications

  • INDICATIONS Oxazepam capsules are 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. Anxiety associated with depression is also responsive to oxazepam therapy. This product has been found particularly useful in the management of anxiety, tension, agitation and irritability in older patients. Alcoholics with acute tremulousness, inebriation, or with anxiety associated with alcohol withdrawal are responsive to therapy.

Common Doses

  • 15 mg
  • 30 mg
  • 10 mg

Dosage

DOSAGE AND ADMINISTRATION Because of the flexibility of this product and the range of emotional disturbances responsive to it, dosage should be individualized for maximum beneficial effects.

Black Box Warning

WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS; ABUSE, MISUSE, AND ADDICTION; and DEPENDENCE AND WITHDRAWAL REACTIONS Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation [see WARNINGS and PRECAUTIONS ] .

Contraindications

  • CONTRAINDICATIONS History of previous hypersensitivity reaction to oxazepam. Oxazepam is not indicated in psychoses.

Side Effects

  • ADVERSE REACTIONS The necessity for discontinuation of therapy due to undesirable effects has been rare. Transient mild drowsiness is commonly seen in the first few days of therapy. If it persists, the dosage should be reduced. In few instances, dizziness, vertigo, headache and rarely syncope have occurred either alone or together with drowsiness. Mild paradoxical reactions; i.e., excitement, stimulation of affect, have been reported in psychiatric patients; these reactions may be secondary to relief of anxiety and usually appear in the first two weeks of therapy.

Interactions

  • No major interactions listed on the FDA label. Always consult a healthcare professional.
