Original abstract
We report sinus bradycardia induced by talipexole hydrochloride in a 65-year-old man with Parkinson disease. Approximately four hours after he had taken 0.8 mg of talipexole hydrochloride, he acutely developed sleepiness, delusion, akinesia, and faintness associated with hypotension and sinus bradycardia. Another similar episode occurred when he had taken talipexole hydrochloride 1.2 mg/day in combination with a daily dose of 200 mg of levodopa and 20 mg of carbidopa. These symptoms persisted for 12 hours and diminished gradually without any specific treatments. Talipexole hydrochloride, a stimulator of both the D2 and alpha 2 receptors probably induced bradycardia and hypotension in the present case.
