Dexdomitor can also be used in veterinary medicine to manage dogs and cats who display anxious, painful or dysphoric behaviors As a guide, the onset of maximal sedation following IM administration is ACP up to 45 minutes, medetomidine 15-20 minutes, methadone/morphine 20-30 minutes, butorphanol 10-20 minutes. Be aware of how long the opioid you have used at premedication will last. If not using any additional intra-operative analgesia you may have to repeat the opioid dose during surgery to ensure the dog has adequate. Ideally use an opioid alone as ACP or medetomidine may produce sedation and relaxation of upper respiratory tract that precipitate airway obstruction. However, if the dog is very distressed/anxious addition of ACP 0.01 - .02mg/kg IM/IV may be required as stress can also lead to airway obstruction. Place these dogs unde Medetomidine is a relatively new sedative analgesic in dogs and cats but some precautions are required when using it. It is a potent alpha 2-adrenoceptor agonist and stimulates receptors centrally to produce dose-dependent sedation and analgesia and receptors centrally and peripherally to cause mark
Medetomidine provides better sedation and analgesia than xylazine and has a longer duration of action (Tyner et al., 1997). Vomiting occurs in about 20% of dogs receiving medetomidine, but is more frequent and prolonged after xylazine. Both xylazine and medetomidine decrease gut motility Medetomidine, commonly known by the brand name Dormitor, is an injectable drug used for sedation in dogs and cats. Medetomidine belongs to a class of drugs known as alpha 2 adrenergic agonists and is similar to clonidine and xylazine. It is a sedative that provides pain relief as well as muscle relaxation The pharmacological restraint and pain relief provided by medetomidine facilitates handling dogs and aids in the conduct of diagnostic or therapeutic procedures. It also facilitates minor surgical procedures (with or without local anesthesia) and dental care where intubation is not required.

Medetomidine Hydrochloride is indicated for use as a sedative and analgesic in dogs over 12 weeks of age to facilitate clinical examinations, clinical procedures, minor surgical procedures not requiring muscle relaxation, and minor dental procedures where intubation is not required In veterinary anesthesia, medetomidine is often used in combinations with opioids (butorphanol, buprenorphine etc.) as premedication (before a general anesthetic) in healthy cats and dogs. It can be given by intramuscular injection (IM), subcutaneous injection (SC) or intravenous injection (IV) 3. Murell JC, Hellebrekers LJ.

The pharmacological restraint and pain relief provided by medetomidine facilitates handling dogs and aids in the conduct of diagnostic or therapeutic procedures. It also facilitates minor surgical procedures (with or without local anesthesia) and dental care where intubation is not required. Spontaneous muscle contractions (twitching) can be expected in some dogs sedate Dogs For premedication one can choose between a combination of an opiate (methadone, Palfium®, oxycodon, fentanyl) with a sedative (acepromazine or droperidol) or an ot2-agonist, such as xylazine or medetomidine (Domitore). In this way, seda-tion is accompanied by (a certain degree of ) an analgesia Medetomidine and dexmedetomidine are mainly used in dogs to facilitate short, noninvasive procedures or as part of a preanesthetic protocol prior to induction of general anesthesia with halothane, isoflurane or sevoflurane.. This drug is an α 2-adrenergic receptor agonist, often used in combination with acepromazine and buprenorphine.. It is a racemic mixture of 2 optical enantiomers. . Medetomidine administered alone caused severe bradycardia, but hypertension was mild and transient. Medetomidine and atropine administered together caused an initial bradycardia, but within 15 minutes there was tachycardia accompanied by a mean.
While xylazine still enjoys popularity in equine and food animal medicine, medetomidine and dexmedetomidine have replaced xylazine in dogs and cats as the alpha-2 of choice, due to their greater alpha-2:alpha-1 affinity (approximately 1620:1 for medetomidine, vs. 160:1 for xylazine). This increased selectivity results in more predictable and effective sedation and analgesia and fewer side effects This prospective crossover study compared the effects of intramuscular administration of medetomidine for sedation on parameters of the abdominal vascular system, measured by enhancement computed tomography (CT), to those of propofol-induced sevoflurane maintenance anesthesia, as a control, in five clinically healthy adult male beagle dogs (11.4-12.8 kg) Atipamezole (brand name Antisedan, also available in generic forms as Revertidine, is a synthetic α 2 adrenergic receptor antagonist indicated for the reversal of the sedative and analgesic effects of dexmedetomidine and medetomidine in dogs. Its reversal effect works by competing with the sedative for α 2-adrenergic receptors and displacing them. . It is mainly used in veterinary medicine.

This study compared anesthetic and cardiorespiratory effects of tiletamine-zolazepam-butorphanol (TT), tiletamine-zolazepam-butorphanol-medetomidine (TTD), and tiletamine-zolazepam-butorphanol-medetomidine with atipamezole reversal 1 hour after TTD administration in dogs. All dogs received glycopyrrolate. All drug combinations effectively induced anesthesia within 5 minutes after IM injection It is unlikely that a dog would require a bolus dose of this magnitude (19.5 mg/kg), under typical clinical conditions. Consistent with other reports, heart rate was lowest in medetomidine-treated groups . In all but the medetomidine premedicated dogs (group 6), average S, D and M blood pressure tended to decrease following MDP induction
The goal of this study was to establish the metabolic stability and determine the metabolic pathway of medetomidine in dog liver microsomes. Consequently, Michaelis-Menten parameters (V max, K m), T 1/2 and CL i were determined.

Allowing dogs to rest quietly for 10 to 15 minutes after injection may improve the response to Medetomidine Hydrochloride. In dogs not responding satisfactorily to treatment with Medetomidine Hydrochloride, repeat dosing is not recommended. Caution should be exercised when handling sedated animals. Handling or any other sudden stimuli may cause a defense reaction in an animal that is sedated. A quick approach for medetomidine enantiomer determination in dog plasma by chiral liquid chromatography-tandem mass spectrometry and application to a pharmacokinetic study. Anisa Bardhi, Department of Veterinary Medical Sciences, Alma Mater Studiorum - University of Bologna, Bologna, Italy. Search for more papers by this author . Anna Zaghini, Department of Veterinary Medical Sciences, Alma. A total of 10 laboratory beagles was used to determine the cardiovascular and respiratory effects of medetomidine. The effects of atropine sulphate and glycopyr-rolate on heart rate were also observed. Xylazine was included as a positive control. Medetomidine induced initial hypertension followed by a longer lasting hypotensive period The volume of reversal agent in the dog is equal to that of sedative administered and, in the cat, half the initial volume (of medetomidine) is used. It should be remembered that while it may be useful to reverse sedation and cardiovascular effects, analgesia is also reversed. If ketamine has been used as part of the anaesthetic protocol, at least 40 minutes should elapse before atipamezole is. Medetomidine, a new sedative‐analgesic for use in the dog and its reversal with atipamezole Medetomidine, a new sedative‐analgesic for use in the dog and its reversal with atipamezole Clarke, K. W.; England, G. C. W. 1989-06-01 00:00:00 ABSTRACT The sedative and physiological effects of intramuscular medetomidine (20 and 40 μg/kg) in dogs were compared with those of xylazine (2 mg/kg)
The purpose of this study was to evaluate the effects of medetomidine administration on the Doppler variables of abdominal arteries. The study population consisted of 20 healthy dogs. The haemodynamic effects of the medetomidine were defined using Doppler variables of the abdominal aorta, renal arteries, cranial mesenteric artery and celiac artery Example protocols - aggressive dogs •medetomidine 5 g/kg + methadone 0.5 mg/kg IM •medetomidine 5 g/kg + methadone 0.5 mg/kg + ketamine 0.5 mg/kg IM •medetomidine 10 g/kg + methadone 0.5 mg/kg ketamine 0.5-1 mg/kg IM •or dexmedetomidine at half the above medetomidine doses ketamine is off-licence when used in these protocol Medetomidine is a relatively new sedative analgesic in dogs and cats but some precautions are required when using it. It is a potent α2-adrenoceptor agonist and stimulates receptors centrally to produce dose-dependent sedation and analgesia and receptors centrally and peripherally to cause marked bradycardia and decrease the cardiac output Medetomidine-ketamine (MK) and dexmedetomidine-ketamine (DK) are widely used to provide general anaesthesia in laboratory animals, but have not been compared directly in many of these species, including rodents. This study aimed to compare the onset and depth of anaesthesia, and changes in vital signs, after intraperitoneal (IP) or subcutaneous (SC) administration of ketamine (75 mg kg-1.
Medetomidine. DrugBank Accession Number. DB11428. Background. Medetomidine is a synthetic compound used as a surgical anesthetic and analgesic. It is normally found as its hydrochloride salt, medetomidine hydrochloride. Medetomidine is an intravenously available alpha-2 adrenergic agonist. The drug has been developed by Orion Pharma Opinions vary on the use of alpha-2 agonists (medetomidine and dexmedetomidine) 5ml/kg/hr in dogs). 10 Avoid hypothermia by providing heat support through warm IV fluids; a fluid line warmer; insulation on the patient's feet (e.g., baby socks or bubble wrap); circulating warm-water blankets; a warm-air circulation system; or dispersive electric heating pad or surgical table. Do not use. Conclusions Medetomidine significantly prolongs the implicit time and lowers the amplitude response of both the a‐ and b‐waves in normal dogs at all flash intensities examined. Clinically, however, medetomidine only minimally affects the retinal responses and is a viable choice for use in dog ERGs
One hundred and nine dogs received atipamezole in the field study (55 dogs received the reversal agent following dexmedetomidine; 54 following medetomidine). The mean age was 5.9 years and ranged between 17 weeks and 16 years. The mean weight was 45.5 lbs (20.7 kg), ranging from 4.8 lbs to 117 lbs (2.2 kg to 53.2 kg). Atipamezole was administered by the IM route of administration, within a. Medetomidine, a potent α2-adrenoceptor agonist, was investigated in open, multicenter clinical trials with patients of various canine and feline breeds (1736 dogs and 678 cats). The purpose of the study was to find an optimal dose of medetomidine for sedation and analgesia in clinical practice and to study how well the intended procedure could be performed under the influence of the drug
Medetomidine Hydrochloride should be administered at the rate of 750 mcg IV or 1000 mcg IM per square meter of body surface. Use the table below to determine the correct dosage on the basis of body weight. Following injection of Medetomidine Hydrochloride, the dog should be allowed to rest quietly for 15 minutes Medetomidine has been reported to decrease tear flow significantly in dogs, cats, and pigs when used as a sedative or analgesic; however, there are no such reports when it comes to rats. The present study aimed to investigate the effect of medetomidine on tear flow in rats. Medetomidine in doses of 50, 100, or 200 µg/kg or a physiological saline solution as the control, were administered.

The study suggested that the reason that the dogs receiving acepromazine exhibited more muscle tremors than those given medetomidine was due to the medetomidine causing muscle relaxation, whereas the acepromazine is not as effective at counteracting the muscle effects of ketamine. Therefore, as ketamine is not often used by vets as a co-induction agent, muscle tremors are less likely to occur.

This thesis evaluated the effects of vatinoxan on the absorption and disposition of medetomidine and other selected drugs in laboratory and client-owned dogs following . intramuscular administration; when the drugs were . combined in the same syringe. The hypothesis was that vatinoxan. 13 dogs, the combination of medetomidine with butorphanol is widely reported in the literature 14 and this combination is licensed for canine sedation in the UK. Compared to medetomidine 15 alone, the addition of butorphanol provides a quicker onset, and more profound sedation 16 whilst using lower doses of medetomidine ( Muir et al., 1999; Girard et al., 2010). 17 Benzodiazepines may also be.
Cardiovascular and pulmonary effects of a new sedative/analgesic (medetomidine) as a preanaesthetic drug in the dog. A study was carried out to investigate the possible usefulness of medetomidine (Farmos Group, Turku, Finland) for premedication prior to general anaesthesia with thiopental sodium and halothane. The main emphasis was laid on the circulatory and respiratory effects of medetomidine Seventy-two healthy dogs required sedation and analgesia for a variety of procedures causing discomfort or pain. They were treated either with the α2-agonist medetomidine at 40 μg/kg (15 intravenou..
In the acepromazine group, systolic arterial pressure was decreased at T10. Within ten minutes after intravenous administration in healthy dogs, fentanyl significantly increased intraocular pressure and fentanyl, butorphanol and medetomidine decreased pupil size All dogs given Me-Mi or Me-B were smoothly and rapidly induced to more profound and longer sedation than those by medetomidine alone. Especially, Me-Mi produced desirable sedation with moderate reflex depression, analgesia, excellent muscle relaxation and immobilization without further side effects. This potent effect of this combination seemed to be induced by a synergistic interaction. The other 6 dogs were premedicated with medetomidine (10 µg/kg, i.m.), and anaesthesia was induced with etomidate (0.5 ± .3mg/kg) followed by i.v. continuous etomidate perfusion (70 ± 20 µg/kg/min), during 60 minutes. Immediately after anaesthesia induction a 18 GA polyethylene catheter was placed in the femoral artery to measure the arterial blood pressure and to extract blood samples.
