Effects of amodiaquine, artesunate and artesunate amodiaquine combination on open field novelty-induced behaviors and spatial memory in healthy mice were studied. Forty mice were used in the open field and fifty each in the radial arm maze and Y maze; mice were assigned into four or five groups of ten each, Group A served as control (distilled water), Groups B, C and D received artesunate (4 mg/kg), amodiaquine (10 mg/kg) and artesunate-amodiaquine combination (4 mg/kg and10 mg/kg) respectively, while Group E animals (for the cognition tests) were given scopolamine (2 mg/kg). Drugs and vehicle were administered orally for three days. Results were analysed by one way analysis of variance followed by a posthoc test. Results showed that artesunate and amodiaquine either in combination or administered singly caused a significant increase in open field novelty-induced horizontal locomotion and rearing. Grooming in the open field showed increments in the artesunate alone and artesunate amodiaquine groups while significant reductions in spatial memory were also seen in the cognition models used.
