Biological Activity

Description Dexmedetomidine is a sedative medication used by intensive care units and anesthetists.
α2 receptor [1]
1.08 nM(Ki )
In vitro

Dexmedetomidine has a relatively high ratio of α2/α1-activity (1620:1 as compared with 220:1 for clonidine) and, therefore, is considered a full agonist of the α2 receptor. This may result in more potent effects of sedation without unwanted cardiovascular effects from α1 receptor activation. The 2-h half-life of dexmedetomidine is nearly 4-fold shorter than that of clonidine, which increases the likelihood that a continuous infusion of dexmedetomidine might be useful for sedation. Dexmedetomidine also has minimum alveolar anesthetic concentration (MAC)-sparing properties, but its use as an anesthetic adjuvant has been complicated by persistent hypotension that has mandated IV fluid administration and vasopressor administration. In addition, its use in large doses is complicated by hypertension from α2 receptor-mediated vascular constriction.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
