Although titrating up and tapering down dosage is very important in people (and maybe dogs), it doesn’t seem to matter as much in horses. Minimal side effects in horses, except low level sedation. To evaluate the analgesic effects of orally administered gabapentin on horses with chronic thoracic limb lameness. The repeated administration of high doses of gabapentin may provide better analgesia in horses than current clinical protocols. Objective: Administration of gabapentin at 40 and 120 mg/kg PO q 12 h for 14 days will not alter serum biochemistry findings or cause adverse effects. Our results suggest that horses tolerate gabapentin up to 120 mg/kg PO q 12 h for 14 days. The analgesic effect of the dosage regimens evaluated in our study warrants further research. Keywords: analgesia, equine, neuropathic pain, plasma disposition, safety. 1. INTRODUCTION. All horses tolerated the PO administration of gabapentin, and no evidence of side effect (e.g. somnolence, depression, sedation, or ataxia) of the drug at either dose (5 or 10 mg/kg bwt) was observed. This textbook includes basic principles of large animal surgery and anesthesia, how to apply those principles to cases and situations, and discover ways of finding answers when you don’t remember the information, are presented with cases that aren’t “textbook” and/or things don’t go as planned. In the study, gabapentin was administered at a dosage of 20 mg/kg, which is considered safe in horses. 3 At this dosage, gabapentin did not improve any measure of lameness in horses with chronic musculoskeletal pain in the thoracic limbs. However, Caldwell et al. (2015) reported no subjective improvement in lameness in horses administered gabapentin at oral doses of 5 and 10 mg kge 1 three times daily for 14 days. A pharmacokinetic study indicated poor oral bioavailability ( 16%) of gabapentin in horses (Terry et al. 2010) compared with reported values in humans (29 83%), e Six horses with chronic lameness referable to musculoskeletal pathology were randomly assigned to one of three treatments: 5 and 10 mg/kg body weight of gabapentin, and placebo administered PO three times daily for 14 days. All horses received each treatment separated by a 2-week interval. Animals: Six healthy adult mares. Methods: Horses received 40 and 120 mg/kg of gabapentin orally q 12 h for 14 days. Horses were examined and scored for ataxia and sedation daily. Serum bio- chemistry variables were analyzed before treatment and days 7 and 14 after gabapentin administration. Plasma disposition of gabapentin was evaluated after the Methods: Following baseline measurement of lameness, horses were administered each of four treatments orally in grain: treatment G, gabapentin (20 mg kg -1) twice daily for 13 doses; treatment F, firocoxib (171 mg once, then 57 mg once daily for six doses); treatment GF, gabapentin and firocoxib at previously stated doses and frequencies; or Discover the correct dosage of gabapentin for horses and learn how it can be used to treat various equine conditions. Gabapentin has a relatively low bioavailability, but no apparent adverse effects following oral administration in horses 75, 76. Further work is needed to assess the clinical effect of gabapentin more objectively in horses with clinical pain. Six horses with chronic lameness referable to musculoskeletal pathology were randomly assigned to one of three treatments: 5 and. 10 mg/kg body weight of gabapentin, and placebo administered PO three times daily for 14 days. All horses received each treatment separated by a 2-week interval. Gabapentin is an anticonvulsant drug effective in humans to control neuropathic pain. In veterinary medicine, is extra-label used in combination with other treatments to control seizures when other drugs are not effective, when drugs are toxic, or Conclusion and clinical importance: Our results suggest that horses tolerate gabapentin up to 120 mg/kg PO q 12 h for 14 days. The analgesic effect of the dosage regimens evaluated in our study warrants further research. Paracetamol and gabapentin are attractive for use in horses because they have an oral route of administration, low cost and few perceived side effects. This review discusses the published evidence regarding the likely efficacy of these drugs, and how best to maximise their use. Our results suggest that horses tolerate gabapentin up to 120 mg/kg PO q 12 h for 14 days. The analgesic effect of the dosage regimens evaluated in our study warrants further research. The apparent low bioavailability of oral gabapentin in horses suggests that gabapentin may need to be administered IV or at very large oral doses to see a positive effect on chronic musculoskeletal pain. Veterinarians have a limited amount of pharmaceutical medications to manage chronic pain in horses. Here are some of the options.
