Alzheimer's patients may need dosing changes in medicines prescribed for other conditions

Patients with Alzheimer's disease (AD) are often prescribed drugs for other conditions -- including diabetes or high blood pressure -- at the same doses as those without dementia. That practice might need to be reexamined in the wake of new mouse studies. The findings suggest that AD could alter absorption of medications from the digestive tract, so dosages might need to be adjusted for these patients.
