(2-Hydroxyethyl) methyldiethylammonium iodide (diethylcholine; DEC) was tested against trihexyphenidyl for its ability to block tremors in two animal models of Parkinsonism tremors. Both DEC (75 mg/kg) and trihexyphenidyl (10 mg/kg) antagonized physostigmine tremors in mice. Both drugs also blocked tremors in rats which received intracaudate injections of carbachol. DEC was more efficacious than trihexyphenidyl in the rat model. No dose-related inhibition of tremors was seen for trihexyphenidyl (5--20 mg/kg) but inhibition by DEC was dose-related (25--50 mg/kg). The ED50 for tremor inhibition in the rat model by DEC was 33 mg/kg. DEC was also shown to cross the blood-brain barrier in mice. The probable mechanism of action of DEC is discussed.
