Donepezil is used to treat dementia (memory loss and mental changes) associated with mild, moderate, or severe Alzheimer's disease. Donepezil will not cure Alzheimer's disease, and it will not stop the disease from getting worse. However, it can improve thinking ability in some patients.
Trifluoperazine is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions).
