Tardive dyskinesia successfully treated with alprazolam.
Tardive dyskinesia is a disorder secondary to prolonged treatment (from 18 months to 3 years) with antipsychotic agents, affecting approximately 15% to 20% of patients. Tardive dyskinesia is characterized by difficulty controlling involuntary movements of the small muscle groups, producing tic-like reactions, muscle rigidity, and difficulty maintaining muscle tone. It is a chronic and unrelenting disorder which may be permanent if not successfully treated. The mechanism of action is thought to be secondary to dopamine hypersensitivity resulting from prolonged deprivation of dopamine on the part of dopamine-sensitive receptors. Theoretically, these receptors have been deprived of the neurotransmitter by chronic treatment with antipsychotic drugs, which are recognized as dopamine-blocking agents. We present a case in which alprazolam was successfully used in treating tardive dyskinesia.
