atypical antipsychotic-induced parkinsonism: a patient case with cyp enzyme implications

Objective: To report a case of Parkinsonism potentially caused by neuroleptic medications. Summary: The case analyzed is that of a 57-year-old male patient referred to a pharmacotherapy service by a neurologist after organic causes of tremor had been ruled out. Iatrogenic cause was suspected and referral expectation was to identify the offending agent or agents and propose alternative therapy. Conclusion: This case illustrates iatrogenic risk associated with neuroleptic medications while illustrating mechanisms of drug interaction via CYP enzymes that can lead to iatrogenic disease.
