The diagnosis and treatment of acquired Myasthenia Gravis in two adult dogs using oral neostigmine bromide

Two adult dogs aged 3.5 and 9 years were diagnosed with acquired Myasthenia Gravis (MG) based on clinical signs and positive response to oral neostigmine bromide (0.25mg/Kg BW) within 4 hours of oral administration. Both patients were successfully treated using neostigmine (1mg/Kg BW daily) alone or with neostigmine (1mg/Kg BW daily) and prednisolone (1mg/Kg BW, q12h) combination. Serum alkaline phosphatase and albumin/ globulin ratio monitored in one of the above patients starting from one month prior to development of generalized clinical signs until complete recovery, showed significant alterations which can be used in diagnosing MG and in monitoring the response to treatment.
