<Li> Tardive dyskinesia: involuntary muscle movements in the lower face and distal extremities; this can be a chronic condition associated with long - term use of antipsychotics . </Li> <P> Anticholinergic drugs are used to control neuroleptic - induced EPS, although akathisia may require beta blockers or even benzodiazepines . If the EPS are induced by an antipsychotic, EPS may be reduced by dose titration or by switching to an atypical antipsychotic, such as aripiprazole, ziprasidone, quetiapine, olanzapine, risperidone, or clozapine . These medications possess an additional mode of action that is believed to negate their effect on the nigrostriatal pathway, which means they are associated with fewer extrapyramidal side - effects than "conventional" antipsychotics (chlorpromazine, haloperidol, etc .), although some research has shown that second generation neuroleptics cause EPS at the same rate as the first generation drugs . </P> <P> Commonly used medications for EPS are anticholinergic agents such as benztropine (Cogentin), diphenhydramine (Benadryl), and trihexyphenidyl (Artane). Another common course of treatment includes dopamine agonist agents such as pramipexole . These medications reverse the symptoms of extrapyramidal side effects caused by antipsychotics or other drugs that either directly or indirectly inhibit dopaminergic neurotransmission . </P> <P> Studies are yet to be undertaken on the optimum dosage of the causative drugs to reduce their side effects (extrapyramidal symptoms (EPS)). </P>
