The aim of the present study was to evaluate a marketed formulation against chemotherapy-induced cognitive dysfunction. The formulation, Mulmina™, contains natural compounds which are known to help in improving function as well as in preventing cognitive decline. All of the phytocon-stituents in the formulation have been tested individually but this is the first study where such a formulation has been evaluated against chemotherapy-induced cognitive decline (CICD) in a mouse model. CICD was induced by cyclophosphamide (50 mg/kg), methotrexate (5 mg/kg), and 5-fluorouracil (5 mg/kg) (CMF), administered intraperitonially. CMF was administered in three cycles, with one injection per week for three weeks. The decline in cognition of the mice was evaluated by a test of locomotor activity (Open Field Test) followed by a test for spatial memory (Morris Water Maze). Biochemical parameters evaluated include brain cytokine levels and BDNF levels via ELISA. Hematological counts were also performed to evaluate any changes in blood profile using a veterinary blood cell counter. Levels of oxidative stress markers with respect to catalase activity and lipid peroxidation were also evaluated in the brain using UV-spectrophotometric analysis. Mulmina™ was able to show significant improvement in cognitive function post chemotherapy when compared to the untreated animals. Apart from improvement in spatial memory, there was also an improvement in biochemical parameters. The particular combination of phytochemicals in Mulmina™ proved themselves successful in alleviating the CICD in this preliminary study and pave a path for future studies which can establish the solid grounds with respect to molecular and pharmacological basis for the mechanism of action of Mulmina™.
