Application


  • Zaleplon in Toxicological Analysis: The development of an LC-MS-MS method to detect Zaleplon along with other benzodiazepines highlights its application in forensic and clinical toxicology, providing essential data for the analysis of Z-drugs in biological samples (Sofalvi et al., 2020).

  • Study of Zaleplon′s Solvent Effects: Research on the solvent effects on Zaleplon′s absorption and fluorescence spectra aids in understanding its chemical behavior in different environments, crucial for its use in pharmaceutical formulations and biochemical studies (Divac et al., 2019).

  • Zaleplon for Insomnia Treatment via Novel Delivery Systems: The development of orodispersible film and tablets for Zaleplon delivery targets improved patient compliance and rapid onset of action in insomnia treatment, emphasizing its role in sleep disorder management (Manda et al., 2018).
