Tiapride. A review of its pharmacodynamic and pharmacokinetic properties, and therapeutic potential in geriatric agitation.

Abstract

Tiapride is a substituted benzamide derivative with selective dopamine D2-receptor antagonist properties which appears to have preferential affinity for extrastriatal dopamine receptors. Animal and clinical studies show that tiapride has anxiolytic properties but the mechanism of action is uncertain. Results from limited studies indicate that the clinical efficacy of tiapride in the treatment of agitation, aggressiveness, anxiety and sleep disorders in the elderly appears superior to that of placebo, chlorpromazine, lorazepam and meprobamate. Tiapride also exerts a beneficial effect on vigilance and alertness in elderly patients and causes less sedation than chlorpromazine. Tiapride is well tolerated at the dosages recommended for elderly patients. Further well designed comparative studies with newer drugs are needed to determine the relative place of tiapride in the treatment of geriatric agitation, and such studies should also address the quality-of-life benefits for the patient. Additional clinical experience to determine the efficacy of tiapride in elderly patients with more than one disease condition, receiving concomitant medications, and/or with renal impairment is also required. However, despite these current limitations, tiapride may have potentially important applications in this difficult area of clinical medicine.
