Biological Activity

Description Xylazine is an α2-Adrenergic receptor agonist, used as a sedative and muscle relaxant.
α2-adrenergic receptor [1]
In vivo Xylazine dose-dependently inhibits norepinephrine release and lipolysis in beagle dogs. Xylazine also tends to decrease epinephrine levels dose-dependently. [1] Xylazine hydrochloride dose- and time-dependently reduces amount of minimum alveolar concentration (MAC) in horse.  Xylazine hydrochloride dose- and time-dependently increases blood glucose concentration in horse. [2] Xylazine induces variable bilateral caudal analgesia extending from coccyx to S3, with minimal sedation, ataxia, and cardiovascular and respiratory depression in standing mares. Xylazine significantly decreases heart and respiratory rates, systolic, diastolic, and mean arterial blood pressure, PCV, hemoglobin concentration, arterial oxygen content, and oxygen transport. [3] Xylazine results in significantly decreased heart rate, increased incidence of atrioventricular block, and decreased cardiac output and cardiac index in horse. [4] Xylazine induces sedation and selective (S3 to Co) analgesia for at least 2 hours in cows. Xylazine significantly decreases heart rate, respiratory rate, rate of ruminal contractions, arterial blood pressure, PaO2, PCV, and total solids concentration, and significantly increases PaCO2, base excess, and bicarbonate concentration in cows. [5] Xylazine severely depresses the N3 field (-75%) and completely abolishes the climbing fiber field (-100%) in the nonanesthetized, decerebrated rat. Xylazine- ketamine injections also severely depresses the N3 field (-75%) and nearly completely abolishes theclimbing fiber field (-90%) in the nonanesthetized, decerebrated rat.[6]

Step 1: Enter information below (Recommended: An additional animal making an allowance for loss during the experiment)

mg/kg g μL

Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)

Calculation results:

Working concentration: mg/ml;

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.
