Influence of MK-467, a peripherally acting α2-adrenoceptor antagonist on the disposition of intravenous dexmedetomidine in dogs.
Growing evidence supports the use of (2R-trans)-N-(2-(1,3,4,7,12b-hexahydro-2'-oxo-spiro(2H-benzofuro(2,3-a)quinolizine-2,4'-imidazolidin)-3'-yl)ethyl) methanesulfonamide (MK-467), a peripherally acting α(2)-adrenoceptor antagonist, in conjunction with the sedative-anesthetic agent dexmedetomidine in animals to avoid hemodynamic compromise. We evaluated the possible effects of different doses o...
متن کاملEffects of alpha 2-adrenoceptor agonists dexmedetomidine and guanfacine on morphine analgesia and tolerance in rats
BACKGROUND Alpha 2 (α(2))-adrenoceptor agonists may be useful for their potential to increase or prolong opioid analgesia while attenuating the development of opioid tolerance. The purpose of this study was to investigate the effects of dexmedetomidine and guanfacine (α(2)-adrenoceptor agonists) on morphine analgesia and tolerance in rats. METHODS Adult male Wistar albino rats weighing 195-20...
متن کاملThe haemodynamic and pharmacologic interaction of medetomidine and peripheral antagonist MK-467 and their dose-dependency in dogs
The alpha-2 agonist, medetomidine (MED), and its pure active enantiomer dexmedetomidine (DMED), are used clinically in small animal practice as potent sedatives, analgesic agents, muscle relaxants, and as adjunct agents for balanced anaesthesia. However, their cardiovascular effects limit their use. The use of constant rate infusion (CRI) for administration of MED was studied in order to provid...
متن کاملBidirectional effects of dexmedetomidine on human platelet functions in vitro.
Platelets express the imidazoline (I)-receptor, I1 and I2, as well as the α2-adrenoceptor. Although dexmedetomidine, a selective α2-adrenoceptor agonist with some affinity for the I-receptor is expected to affect platelet function, the effects of dexmedetomidine on platelet functions remain unclear. In the present study, we investigated the effects of dexmedetomidine on human platelet functions...
متن کاملActivation of α2 adrenoceptor attenuates lipopolysaccharide-induced hepatic injury.
Sepsis induces hepatic injury but whether alpha-2 adrenoceptor (α2-AR) modulates the severity of sepsis-induced liver damage remains unclear. The present study used lipopolysaccharide (LPS) to induce hepatic injury and applied α2-AR agonist dexmedetomidine (DEX) and/or antagonist yohimbine to investigate the contribution of α2-AR in LPS-induced liver injury. Our results showed that LPS resulted...
