A total of 34 subjects were enrolled and 29 subjects completed the study. Patients reported significant pain relief on NPRS by end of 4 weeks. Subjects also reported similar magnitude of improvements in fibromyalgia and its impact on daily life by the end of 4 weeks. MOS results showed subjects reporting improved sleep quantity (on average, 1.2 hours over baseline) with gradual and statistically significant improvement in quality. Improvements in primary and secondary measurements were reflected in PGIC, with significant improvement in patients’ impression of fibromyalgia by week 8.
Lack of research: The research analyzing the therapeutic effects of Gabapentin in dogs is severely lacking. The studies that have been published tend to include a very small number of canine participants. Follow-up research has been relatively unfocused and does not seem to expand off of previous findings (or lack thereof). Maybe researchers have thrown in the towel on Gabapentin in canines due to availability of more proven, effective treatments.
