General description
A Certified Solution Standard for use in LC or GC applications from forensic and forensic toxicology analysis to urine drug testing. N-Desmethylclobazam, found in urine, serum, and plasma, is the pharmacologically active, major metabolite of clobazam.
Application
- Impact on bioavailability in epilepsy treatment: A study discussed the implications of N-Desmethylclobazam on drug to drug interactions and neuropsychological impact when used as add-on therapy in drug-resistant epilepsies, highlighting its role in enhancing therapeutic bioavailability (Pietrafusa et al., 2023).
- Research on pharmacokinetic variability: Research explored the pharmacokinetic variability of N-Desmethylclobazam, emphasizing its influence by age, drug interactions, and biochemical markers of toxicity in patients with epilepsy, contributing to a deeper understanding of its pharmacological properties (Heger et al., 2024).
- Evaluation of drug-drug interactions: A comprehensive analysis investigated potential drug-drug interactions between N-Desmethylclobazam and anti-seizure medications, providing insights into its safe and effective use in clinical settings (Gaston et al., 2023).
- Synergistic effects in epilepsy management: A multicenter study on the cenobamate-clobazam interaction revealed both pharmacokinetic interactions and evidence of synergy, underscoring N-Desmethylclobazam′s potential to enhance treatment outcomes in epilepsy (Osborn and Abou-Khalil, 2023).
- Analysis of metabolites in forensic science: Research on the measurement of benzodiazepine receptor agonists′ metabolites, including N-Desmethylclobazam, outlined its detection and concentration levels in urine, offering applications in forensic toxicology (Volkova et al., 2023).

The effect of cimetidine on the single dose pharmacokinetics of orally administered clobazam and N-desmethylclobazam (NDMC) was studied in volunteers. Cimetidine inhibited the elimination of both clobazam and NDMC and inhibited the rate of formation of NDMC from clobazam. The

A four-year-old male with symptomatic generalized epilepsy presented with ataxia, eye rolling, and episodes of back arching which were of non-epileptic origin following the introduction of clobazam at 0.75mg/kg/day. Concurrent antiepileptic medication was lamotrigine at 13mg/kg/day. Clobazam plasma levels were
