Do not use anticholinergic drugs to treat the motor symptoms of drug-induced parkinsonisms.

Type of practice


Topic Area


Although anticholinergic drugs have been widely used in the control of parkinsonian symptoms in Parkinson’s disease and in parkinsonisms (including drug-induced parkinsonism), the current evidence shows that such drugs have a limited benefit on tremor and are asscociated with cognitive and neuropsychiatric side effects.Thus, the use of anticholinergics should be limited in patients with comorbidities as cognitive impairment or clinically significant psychiatric illness. Therefore, the use of anticholinergic drugs is not recommended for the treatment of motor symptoms in drug-induced parkinsonisms.
