General description

A Certified Snap-N-Spike® Solution appropriate for use as starting material in calibrators or controls for a variety of LC/MS or GC/MS applications from forensic analysis and clinical toxicology to urine drug testing and pharmaceutical research. Estazolam is a benzodiazepine prescribed for the short-term treatment of insomnia. Sold under trade names such as ProSom or Eurodin, estazolam is often abused recreationally to achieve a high or when long-term use is continued against physician advice.

Application


  • Estazolam in environmental trace analysis: A study employing ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) detailed the detection of Estazolam among other psychotropic medications in environmental samples, underscoring the method′s precision and application in monitoring environmental contamination by pharmaceutical residues (Wang et al., 2024).

  • Estazolam and insomnia post-coronavirus disease: Research analyzed insomnia prevalence among COVID-19 survivors, identifying Estazolam as part of the therapeutic regimen. This study highlights the ongoing relevance of Estazolam in addressing sleep disorders associated with long-term recovery from significant health events (Lu et al., 2024).

  • Comparative analysis of Estazolam for post-stroke insomnia: A network meta-analysis compared various treatments for post-stroke insomnia, including Estazolam, providing insights into its effectiveness relative to other therapeutic options. This study contributes to understanding optimal treatment strategies for insomnia in post-stroke patients (Song et al., 2023).
