Drug dosing in the elderly patients

The geriatric population is often arbitrarily

defined as patients who are older than 65 years,

and many of these people live active and healthy

lives.

 The aging process is more often associated with

physiologic changes during aging rather than

purely chronological age.

Classification of Elderly

1. Young Old (Aged 65-75 years old)

2. Old (Aged 75-85 Years old)

3. Old Old (Age >85 Years old)

 Performance capacity and the loss of homeostatic

reserve decrease with advanced age but occur to

a different degree in each organ and in each

patient.

 Decreased cognitive function in some geriatric

patients, complicated drug dosage schedules,

and/or the high cost of drug therapy may result

in poor drug compliance, lack of drug efficacy,

drug interactions, and/or drug intoxication.
