CLOBAZAM
|
Clobazam has been used to treat anxiety and epilepsy since 1970s. In the US clobazam was approved for marketing in October of 2011 for the adjunctive treatment of seizures associated with Lennox-Gastaut syndrome. It is also approved for adjunctive therapy for epilepsy in patients who have not responded to first-line drugs and in children who are refractory to first-line drugs. The mechanism of action for clobazam is not fully understood but is thought to involve what is known as potentiation of GABAergic neurotransmission resulting from binding at a benzodiazepine site at the GABA(A) receptor. Possible side effects: constipation, fever, drowsiness, sedation, ataxia, aggressive behavior, lethargy, drooling, and irritability. Other side effects include: urinary tract infection, pneumonia, cough, dysphagia, dysarthria, bronchitis, insomnia, fatigue, decreased appetite, and increased appetite.

Clobazam is a benzodiazepine which belongs to the same family of drugs that includes lorazepam (Ativan), diazepam (Valium), midazolam (Versed) and clonazepam (Klonopin). Clobazam is different from the other benzodiazepines because it is utilized for the long-term treatment of epilepsy due to its effectiveness and relatively low tendency to produce sedation.
The medication is indicated for use in patients as an add- on medication for seizures associated with Lennox-Gastaut syndrome. Patients must be 2 years of age or older.

Duration: A long acting benzodiazepine which focuses primarily on anxiolytic and anticonvulsant properties. It is used medically to treat epilepsy, and this along with its relatively many negative side-effects and contraindications in comparison with other benzodiazepines means it isn't frequently used recreationally. NOTE: 20mg of Clobazam is approximately equal to 10mg Diazepam. | |||

IMPORTANT WARNING:
Clobazam may increase the risk of serious or life-threatening breathing problems, sedation, or coma if used along with certain medications. Tell your doctor if you are taking or plan to take: antidepressants; medications for anxiety, mental illness, and seizures; sedatives; sleeping pills; opioids such as codeine, fentanyl (Duragesic, Subsys), morphine (Astramorph, Kadian), or oxycodone (in Percocet, in Roxicet, others); or tranquilizers. Your doctor may need to change the dosages of your medications and will monitor you carefully. If you take clobazam with any of these medications and you develop any of the following symptoms, call your doctor immediately or seek emergency medical care immediately: unusual dizziness, lightheadedness, extreme sleepiness, slowed or difficult breathing, or unresponsiveness. Be sure that your caregiver or family members know which symptoms may be serious so they can call the doctor or emergency medical care if you are unable to seek treatment on your own. Drinking alcohol or using street drugs during your treatment with clobazam also increases the risk that you will experience these serious, life-threatening side effects. Do not drink alcohol or use street drugs during your treatment.

Liver:
Therapy with clobazam has not been associated with serum aminotransferase elevations, and clinically apparent liver injury from clobazam has yet to be reported and must be rare, if it occurs at all.
Clobazam Hepatotoxicity:
Limited data are available on the hepatotoxicity of clobazam. In clinical trials, clobazam was not associated with an increased frequency of serum aminotransferase elevations as compared to placebo treatment, and there were no instances of clinically apparent liver injury. No individual case reports of clobazam hepatotoxicity have been published since its wide spread clinical availability. Liver injury from benzodiazepines is quite rare, but isolated instances of hepatotoxicity have been reported for clorazepate and clonazepam, two other benzodiazepines used predominantly in the therapy of epilepsy. Thus, clinically apparent liver injury due to clobazam must be rare, if it occurs at all.E Likelihood score: E (unlikely cause of clinically apparent liver injury).
