Abstract:
The involvement of a drug must be suspected in each patient suffering from a movement disorder. Besides classical neuroleptics used as antipsychotics (butyrophénones, phenothiazines or benzamides), many drugs, mainly "hidden" neuroleptics (prescribed as antinausea, antivomiting, antivertigo, antispasmodic or antihypertensive drugs) or agents prescribed in psychiatric (antidepressants, lithium) or neurological (levodopa in Parkinson's disease, antiepileptics) diseases are known to be able to reveal or produce a movement disorder. Other drug prescribed in internal medicine can also be involved. This review discusses the main characteristics of drug-induced movement disorders as well as their pharmacological approach.
