Bruera, E., El Osta, B., Valero, V., Driver, L.C., Pei, B.L., Shen, L., . . . Palmer, J.L. (2007). Donepezil for cancer fatigue: A double-blind, randomized, placebo-controlled trial. Journal of Clinical Oncology, 25, 3475–3481.
Patients received either donepezil or placebo (5 mg) orally every morning for seven days. A research nurse contacted patients by daily telephone calls to assess symptoms and treatment toxicity. Patients were evaluated at the clinic on day 8. Patients returned for a final assessment on day 15, and those who chose to continue taking donepezil were provided with a two-week supply of the drug. Fatigue outcomes were assessed at baseline, day 8, and day 15.
The donepezil intervention did not show any improvement in fatigue in comparison to the placebo, as no significant difference was seen between groups at baseline and on day 8 for FACIT-F fatigue intensity scores.
