NCT02550665

Brief Summary

This study evaluates the side effects of dose escalation in the treatment of donepezil 23mg for patients with Alzheimer's disease. Investigators randomly divide participants into three groups according to the dose escalation method; no titration, 15mg of donepezil for a month before escalation to 23mg, and alternating of 10mg and 23mg for a month before escalation to 23mg.

Outcome Measures

Primary Outcomes (1)

  • Incidence of treatment-emergent adverse events (safety and tolerability)

    adverse events (nausea, vomiting, diarrhea, anorexia, abdominal pain, headache and other unpredicted adverse events)are asked and assessed using 3 grade scale (mild, moderate, severe)

    Change from baseline at 4 week

Secondary Outcomes (9)

  • blood WBC

    12 week

  • blood BUN

    12 week

  • blood Creatinine

    12 week

  • blood sodium

    12 week

  • blood potassium

  • +4 more secondary outcomes
