Excerpt

 

An acute dystonic reaction is characterized by involuntary contractions of muscles of the extremities, face, neck, abdomen, pelvis, or larynx in either sustained or intermittent patterns that lead to abnormal movements or postures. The symptoms may be reversible or irreversible and can occur after taking any dopamine receptor-blocking agents. The etiology of acute dystonic reaction is thought to be due to dopaminergic-cholinergic imbalance in the basal ganglia. Reactions usually occur shortly after initiation of an offending agent or an increased dose of a possible offending agent. Anticholinergic agents and benzodiazepines are the most commonly used agents to reverse or reduce symptoms in acute dystonic reaction. Acute dystonic reactions are often transient but can cause significant distress to the patient. Although rare, laryngeal dystonia can cause life-threatening airway obstruction.
