Bornaprine (brand name Sormodrem) is a synthetic anticholinergic medication that is primarily used to treat Parkinson's disease.

[4][5][6] Additional tests revealed that bornaprine was significantly more effective than nicotine at antagonizing choline.

[7] Early clinical trials with Parkinsonian patients (completed in Germany), showed that bornaprine was successful at treating many of the key side-effects of Parkinson's including akinesia, language, tremors, and psychological symptoms.

[8] Bornaprine has been characterized as a very potent anticholinergic medication and further clinical trials have indicated its effectiveness at treating parkinsonian tremors.

[13] Single oral doses of bornaprine were successfully excreted in urine and feces in rats, dogs, and humans.

Bornaprine most effectively treats the tremors associated with Parkinson's and also helps bradykinesia, hypokinesia, and posture and facial expression.

[11] LD50 tests performed on rodents revealed that 26 mg/kg intravenously and 112 mg/kg subcutaneously administered amounts of bornaprine were toxic.
