Use of cannabidiol-dominant extract as co-adjuvant therapy for type 2 diabetes mellitus treatment in feline: case report

Abstract

Introduction: Diabetes mellitus (DM) is a common endocrinopathy in felines. Treatment is based on glycemic control and management of clinical signs by insulin administration coupled with a low-carbohydrate and high-protein content diet. However, achieving adequate remission or glycemia control is not always possible. Effects of cannabinoids on the regulation of glucose uptake and the incidence of diabetes have been observed in experimental models. Nevertheless, little is known about their possible relevance in controlling this condition in veterinary and human medicine. Case presentation: This is a case study of an 18-year-old, neutered, mixed-breed female domestic longhair cat diagnosed with type 2 diabetes mellitus. She was treated with long-acting glargine (3 to 5 IU/12 hs), and her diet changed to ultra-processed commercial food for diabetic cats. Three months after the start of the treatment with insulin, Cannabidiol (CBD)-enriched extract in handmade olive oil, THC: CBD ratio = 1:24, was incorporated. The route of administration was oromucosal. After three months, the glycemia was reduced. The patient decreased the polyuria/polydipsia, recovered sleep cycles, remained attentive to all movements, and increased her physical activity. Conclusion: This report provides evidence that using a CBD-rich extract was effective as a co-adjuvant in alleviating clinical signs of DM and concurrent disorders, allowing for the reduction of insulin intake.
