Chemical Analysis and Molecular Modelling of Cyclodextrin-Formulated Propofol and Its Sodium Salt to Improve Drug Solubility, Stability and Pharmacokinetics (Cytogenotoxicity)

Today's cyclodextrin,

today’s cyclodextrin:
Propofol is a widely used general anesthetic in clinical practice, but its use is limited by its water-insoluble nature and associated pharmacokinetic and pharmacodynamic limitations. Therefore, researchers have been searching for alternative formulations to lipid emulsion to address the remaining side effects. In this study, novel formulations for propofol and its sodium salt Na-propofolat were designed and tested using hydroxypropyl-β-cyclodextrin (HPβCD). The formulated compounds showed no cytotoxicity and genotoxicity compared to the reference. The CD-based formulations of propofol and its sodium salt may be a promising option and a plausible alternative to conventional lipid emulsions.

Comparison of the Efficacy and Safety of Adamgammadex with Sugammadex for Reversal of Rocuronium-Induced Neuromuscular Block: Results of a Phase II Clinical Trial

drug development, drug discovery, , ,

The success of Sugammadex inspired several further cyclodextrin research, including the development of other antidotes and discovering “follow-up” compounds for the same indication. The most advanced candidate in this field is Adamgammadex (developed by Adamerck) with its efficacy recently compared to SGM in a Phase II trial lead by Sichuan University. Although it was used in 2-3 times higher concentrations, the previously reported adverse effects were not observed in this study, including anaphylaxis, haemorrhage, recurarization, abnormal basic vital signs, or lengthened QRS intervals and QT intervals. Adamgammadex was found to be effective for reversing rocuronium-induced neuromuscular block as sugammadex.
