Use of olanzapine for elderly patients with psychotic disorders: a review

The number of elderly persons with psychosis will increase with the increasing geriatric population. Olanzapine is one of the newer atypical antipsychotics with efficacy for positive and negative symptoms and safer side effect profile compared to conventional antipsychotics. The manuscript describes the pharmacology, efficacy and tolerability studies, adverse effects and dosing considerations in the elderly. Further studies are needed to fully assess the efficacy and safety of olanzapine in the elderly. Current research supports a role for olanzapine in treating elderly patients with schizophrenia, schizoaffective disorder and behavioral and psychological symptoms of dementia.
