Bradycardia due to trihexyphenidyl hydrochloride
Drug Intelligence & Clinical Pharmacy
|October 1, 1986
Summary
A patient with chronic schizophrenia experienced paradoxical sinus bradycardia after treatment with trihexyphenidyl hydrochloride. This rare side effect highlights the need for physician awareness of anticholinergic drug reactions.
Area of Science:
- Psychiatry
- Pharmacology
- Cardiology
Background:
- Anticholinergic drugs, such as trihexyphenidyl hydrochloride, are commonly prescribed for managing symptoms in chronic schizophrenia.
- These medications are typically used to counteract extrapyramidal side effects associated with antipsychotic treatments.
Observation:
- A case study involving a patient with chronic schizophrenia revealed an unexpected adverse reaction during treatment.
- The patient was administered trihexyphenidyl hydrochloride, a widely used anticholinergic agent.
Findings:
- Paradoxical sinus bradycardia, a slowing of the heart rate, was observed in the patient.
- This cardiac side effect was specifically linked to trihexyphenidyl hydrochloride and not observed with other anticholinergic medications.
Implications:
- The findings underscore a rare but significant adverse effect of trihexyphenidyl hydrochloride.
- Clinical awareness among healthcare providers is crucial for identifying and managing this specific anticholinergic drug reaction in psychiatric patients.
