Klonopin (Clonazepam) - Summary

 
 



KLONOPIN SUMMARY

Klonopin, a benzodiazepine, is available as scored tablets with a K-shaped perforation containing 0.5 mg of clonazepam and unscored tablets with a K-shaped perforation containing 1 mg or 2 mg of clonazepam.

Seizure Disorders

Klonopin is useful alone or as an adjunct in the treatment of the Lennox-Gastaut syndrome (petit mal variant), akinetic and myoclonic seizures. In patients with absence seizures (petit mal) who have failed to respond to succinimides, Klonopin may be useful.

In some studies, up to 30% of patients have shown a loss of anticonvulsant activity, often within 3 months of administration. In some cases, dosage adjustment may reestablish efficacy.

Panic Disorder

Klonopin is indicated for the treatment of panic disorder, with or without agoraphobia, as defined in DSM-IV. Panic disorder is characterized by the occurrence of unexpected panic attacks and associated concern about having additional attacks, worry about the implications or consequences of the attacks, and/or a significant change in behavior related to the attacks.

The efficacy of Klonopin was established in two 6- to 9-week trials in panic disorder patients whose diagnoses corresponded to the DSM-IIIR category of panic disorder (see CLINICAL PHARMACOLOGY: Clinical Trials).

Panic disorder (DSM-IV) is characterized by recurrent unexpected panic attacks, ie, a discrete period of intense fear or discomfort in which four (or more) of the following symptoms develop abruptly and reach a peak within 10 minutes: (1) palpitations, pounding heart or accelerated heart rate; (2) sweating; (3) trembling or shaking; (4) sensations of shortness of breath or smothering; (5) feeling of choking; (6) chest pain or discomfort; (7) nausea or abdominal distress; (8) feeling dizzy, unsteady, lightheaded or faint; (9) derealization (feelings of unreality) or depersonalization (being detached from oneself); (10) fear of losing control; (11) fear of dying; (12) paresthesias (numbness or tingling sensations); (13) chills or hot flushes.

The effectiveness of Klonopin in long-term use, that is, for more than 9 weeks, has not been systematically studied in controlled clinical trials. The physician who elects to use Klonopin for extended periods should periodically reevaluate the long-term usefulness of the drug for the individual patient (see DOSAGE AND ADMINISTRATION).

Acupuncture Versus Clonazepam in Burning Mouth Syndrome [Completed]
Objective: Burning mouth syndrome (BMS) is chronic oral condition characterized with burning symptoms which affects perimenopausal and postmenopausal women. It seems that neuropathy might be the underlying cause of the condition. There are still insufficient data regarding successful therapy. The aim of this study was to compare efficacy of acupuncture and clonazepam in 42 BMS patients (38 women, 4 men), age range 66. 712 years. Methods: Patients were randomly divided into two groups. Acupuncture was performed in group I during four weeks, 3 times per week on the points ST 8, GB 2, TB 21, SI 19, SI 18, LI 4 on both sides of the body as well as GV 20, each session lasted half an hour. Group II patients took clonazepam two times a day (0. 5 mg) in the morning and after two weeks two tablets (0. 5 mg) in the morning and in the evening during the next two weeks. Prior to and one month after either therapy, participants fulfilled questionnaires: visual analogue scale, Beck depression inventory, LANSS pain scale, 36-item short form Health Survey (SF-36) and Montreal Cognitive Assessment (MoCA). Statistical analysis was performed by use of Student t test and Pearson's correlation test. P values lower than 0. 05 were considered significant.
