Klonopin, known generically as clonazepam, is a benzodiazepine that has been extensively studied and used for various medical conditions, including panic disorder, seizure disorders, and other neurological and psychiatric conditions.
Clinical Trials for Panic Disorder
The efficacy of Klonopin in treating panic disorder was demonstrated in two double-blind, placebo-controlled studies involving adult outpatients with a primary diagnosis of panic disorder, with or without agoraphobia, as defined by the DSM-IIIR and later DSM-V criteria.
-
Study 1: This was a 9-week, fixed-dose study that included Klonopin doses of 0.5, 1, 2, 3, or 4 mg/day or placebo. The study consisted of four phases: a 1-week placebo lead-in, a 3-week upward titration, a 6-week fixed dose, and a 7-week discontinuance phase. The 1 mg/day group showed a significant difference from the placebo group, with a reduction of approximately 1 panic attack per week from baseline. At the endpoint, 74% of patients receiving 1 mg/day of clonazepam were free of full panic attacks, compared to 56% of placebo-treated patients[1][3].
-
Study 2: This was a 6-week, flexible-dose study involving Klonopin in a dose range of 0.5 to 4 mg/day or placebo. The study included a 1-week placebo lead-in, a 6-week optimal-dose phase, and a 6-week discontinuance phase. The mean clonazepam dose during the optimal dosing period was 2.3 mg/day. Similar to Study 1, there was a reduction of approximately 1 panic attack per week from baseline. At the endpoint, 62% of patients receiving clonazepam were free of full panic attacks, compared to 37% of placebo-treated patients[1][3].
Long-Term Use
The effectiveness of Klonopin in long-term use, beyond 9 weeks, has not been systematically studied in controlled clinical trials. Therefore, physicians are advised to periodically reevaluate the long-term usefulness of the drug for individual patients[1][3].
Other Clinical Uses
While Klonopin is FDA-approved primarily for the treatment of specific seizure disorders, such as the Lennox-Gastaut syndrome, it has also been used off-label for various other conditions, including chronic pain syndromes like myofascial pain syndrome. An open clinical treatment trial involving 46 patients with chronic pain associated with myofascial pain syndrome showed that clonazepam could provide partial pain relief, although this use is not FDA-approved[4].
