Should doses exceeding 0.2 mg/kg of oral meloxicam be given to reduce surgical recovery time in rabbits and should twice daily administration be considered?

Abstract

PICO question \nIn reducing surgical recovery time in rabbits (Oryctolagus cuniculus), should doses exceeding 0.2 mg/kg of oral meloxicam be given and is twice daily administration more effective than a single daily dose? \n\xa0 \nClinical bottom line \nCategory of research question \nTreatment \nThe number and type of study designs reviewed \nNine papers were critically reviewed, yet no studies were found to directly investigate the effects of twice daily dosing with meloxicam postoperatively in rabbits. There were five descriptive, non-comparative case series; two nonblinded parallel group randomised control trials; one blinded, placebo-controlled parallel group randomised trial and one prospective, randomised crossover trial \nStrength of evidence \nWeak \nOutcomes reported \nThe current recommended oral dose of meloxicam in rabbits of 0.2–0.3 mg/kg once a day was consistently described as inadequate for postoperative analgesia following surgery (Delk et al., 2014). Instead, higher doses of 1–1.5 mg/kg were required to reach a similar peak plasma concentration as found to be clinically effective in other species, such as canines, and provide a better degree of analgesia in rabbits (Montoya et al., 2004; and Delk et al., 2014). Although no studies were found evaluating twice daily administration of meloxicam, the available evidence suggests a dose exceeding 0.2–0.3 mg/kg daily is required for adequate postoperative analgesia in rabbits. Whether this increased dose could be given twice daily should be investigated, providing scope for future research \nConclusion \nFurther studies are required to directly assess the benefits of twice daily oral meloxicam. However, it is possible that a dose exceeding 0.2–0.3 mg/kg is required and therefore higher doses should be considered in these studies \n\xa0 \nHow to apply this evidence in practice \nThe application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources. \nKnowledge Summaries are a resource to help reinforce or inform decision making.
