The existing evidence suggests an association between depression and memory impairment. The objective of present study was to assess the effect of low dose caffeine with duloxetine and bupropion on memory.
Materials and Methods:

Mice were divided randomly into seven groups. Intra-peritoneal treatment of normal saline (10 ml/kg), caffeine (10 mg/kg), duloxetine (10 mg/kg), bupropion alone (10 mg/kg), caffeine + duloxetine (5 mg/kg, each), caffeine + bupropion (5 mg/kg, each), and bupropion + duloxetine (5 mg/kg, each) were given to groups I-VII, respectively. Elevated plus maze was used to evaluate transfer latency (TL) and Morris water maze was used to estimate the time spent in target quadrant.
Results:

Caffeine with duloxetine treated group was better than other combination treated groups in terms of a significant decrease in TL and increase in the time spent in target quadrant recorded.
Conclusion:

Combining lower dose of caffeine with duloxetine may enhance cognitive benefits than respective monotherapies.
