Although geriatric patients are the major recipients of drugs, most research during drug development is conducted in healthy younger adults. Safe and effective drug therapy in the elderly requires an understanding of both drug disposition and response in older individuals. One of the major issues in studying the elderly relates to the ability to study a large number of people in a minimally invasive way. ⋯ Population pharmacokinetics can be used to aid in designing large clinical trials by simulating virtual data based on the study design. It can also be used to assess consistency of drug exposure and evaluate its effect on clinical outcome. This article reviews the methods used in pharmacokinetic modeling, as well as providing examples of population pharmacokinetic modeling, highlighting its application to geriatric psychiatry.

Incidence and outcome of depressive symptoms in nursing home patients in the Netherlands.
To assess incidence and outcome of depressive symptoms among nursing home (NH) patients and to identify clinical characteristics predicting onset and persistence of depressive symptoms. ⋯ Pre-admission factors and transition may largely be responsible for depressive symptoms among nursing home patients. The observed substantial decrease in prevalence of depressive symptoms over six months is largely due to remission of depressive symptoms present at baseline. Adaptation of nursing home patients to pre-admission factors, facilitated by the nursing home environment, may explain this observed decrease of depressive symptoms. Future studies should evaluate interventions targeted at patients with higher GDS-scores (18-30).
