Recovery scores following dexmedetomidine were better compared to medetomidine. Horses administered dexmedetomidine required more than 50% of the medetomidine dose to reach equivalent sedation. During isoflurane anaesthesia, cardiopulmonary function was comparable between the two groups Combined mean end-tidal isoflurane concentration for all dose levels was higher in dogs that received medetomidine, compared with dexmedetomidine. Recovery time was significantly prolonged in dogs treated at the M40/D20 dose level, compared with the other dose levels. After induction, blood pressure decreased below reference range and heart rate increased in dogs treated at the M0.4/D0.2 dose level, whereas blood pressure was preserved in dogs treated at the M40/D20 dose level. However, dogs. Medetomidine, an alpha2-adrenoceptor agonist, is a racemic mixture of two optical stereoisomers: dexmedetomidine (the active enantiomer) and levomedetomidine. Both medetomidine and dexmedetomidine.. MEDETOMIDINE (Domitor) * * The information contained herein also applies to dexmedetomidine (Dexdomitor). When referring to dose recommendations, use 1/2 of the mg/kg medetomidine dose if you are administering dexmedetomidine. This will amount to the same volume since the Dexdomitor solution is 1/2 the strength of Domitor The objective of this study was to evaluate dexmedetomidine as a premedicant in dogs prior to propofol-desflurane anaesthesia, and to compare it with medetomidine. Six healthy dogs were anaesthetized. Each dog received intravenously (i.v.) five preanaesthetic protocols: D1 (dexmedetomidine, 1 microg/kg, i.v.), D2 (dexmedetomidine, 2 microg/kg, i.v.), M1 (medetomidine, 1 microg/kg, i.v.), M2 (medetomidine, 2 microg/kg, i.v.), or M4 (medetomidine, 4 microg/kg, i.v.). Anaesthesia was induced.
Medetomidine and dexmedetomidine: a review of cardiovascular effects and antinociceptive properties in the dog Joanna C Murrell BVSc, PhD, Diploma ECVA Department of Clinical Sciences of Companion Animals, Faculty of Veterinary Medicine, University of Utrecht, Utrecht, the Netherland . The present trial aimed at elucidating these uncertainties using the nociceptive withdrawal reflex model. This model allows for quantification of analgesia by measuring specific. Because dexmedetomidine was identified as the active enantiomer of medetomidine, the dose of dexmedetomidine administered is normally half that of the medetomidine; this is due to the absence of levomedetomidine that comprises 50% of the medetomidine racemate. Three studies in other species administered equal amounts of ketamine combined with doses of medetomidine or dexmedetomidine assumed by the researchers to be equipotent. A study of the golden-headed lion tamari
Rankin, 2015). Medetomidine is an alpha-2 adrenoceptor that is used to create relaxation and pain relief. It is more specific to re-ceptors than xylazine and has a greater pharmacological tendency to alpha-2 receptors (Sawyer, 2008). Dexmedetomidine is a 2A- adrenoceptor and is actually an isomer of Medetomidine, whic Medetomidine had a greater influence on the increase in glucose concentration than DEX. The developed models demonstrate the use of mechanistic and mPBPK/PD models for the analysis of clinically obtainable in vivo data Medetomidine vs Dexmedetomidine: What is the difference? Medetomidine and Dexmedetomidine are both alpha-2 adrenergic receptor agonists that may be used in small animal practice. This webinar provides an overview of both agents, and utilizes an evidence-based approach to outline the differences between them Medetomidine is an equal mixture of two optical enantiomers: dexmedetomidine (see previous discussion) and levomedetomidine. Dexmedetomidine is the active component, whereas levomedetomidine is considered pharmacologically inactive (although it may play a role in drug interactions). 2 Dexmedetomidine decreased the incidence of intraoperative (2 vs. 13 patients) and postoperative (5 vs. 16 patients) tachycardia. Dexmedetomidine also decreased the need for additional doses of fentanyl (3.1 vs. 5.4), the increments of enflurane (4.4 vs. 5.6), the need for beta blockers (3 vs. 11 patients), and the incidence of fentanyl-induced muscle rigidity (15 vs. 33 patients) and postoperative shivering (13 vs. 23 patients)

The stimulation of these receptors leads to a decrease in norepinephrine release from presynapti The marketed product is a racemic mixture of two stereoisomers; dexmedetomidine is the isomer with more useful effects, and is now marketed as Dexdomitor. The free base form of medetomidine is sold as Selektope for use as an antifouling substance in marine paints Medetomidine is the racemic mixture of the active D-enantiomer (dexmedetomidine) and the inactive L-enantiomer. Medetomidine is no longer commercially available and has been replaced by its racemic isomer dexmedetomidine (Dexdomitor®) . 160:1 for xylazine). This increased selectivity results in more predictable and effective sedation and analgesia and fewer side.

Introduction. The alpha2-adrenergic agonist dexmedetomidine is the active optical enantiomer isolated from the racemic compound medetomidine. Although alpha2-adrenergic agonists have been used in veterinary anesthesia since the late 1960s, the development of dexmedetomidine in the 1990s has led to a renewed interest in the perioperative use of alpha2-agonists in human beings. 1 In dogs and. dexmedetomidine and midazolam in patients that are critically ill.

Dexmedetomidine, sold under the trade name Precedex among others, is an anxiolytic, sedative, and pain medication. Dexmedetomidine is notable for its ability to provide sedation without risk of respiratory depression (unlike other commonly used drugs such as propofol and fentanyl) and can provide cooperative or semi-rousable sedation. Similar to clonidine, it is a sympatholytic drug that acts. This review compares the effects of peripheral dexamethasone and dexmedetomidine on postoperative analgesia. We included six randomized controlled trials (354 patients) through a systematic literature search. We found that analgesia duration was comparable between dexamethasone and dexmedetomidine (58.59 min, 95% CI (confidence interval), − 66.13, 183.31 min) with extreme heterogeneity

Dexmedetomidine has characteristics suggesting it may substitute for intra-operative remifentanil during general anaesthesia, but existing literature has reported conflicting results. We undertook this meta-analysis to investigate whether general anaesthesia including dexmedetomidine would result in less postoperative pain than general anaesthesia including remifentanil.
