Biperiden is an antiparkinsonian agent of the anticholinergic type.
Biperiden is used for the adjunctive treatment of all forms of Parkinson’s disease and for reduced sweating in methadone users (postencephalitic, idiopathic, and arteriosclerotic). It seems to exert better effects in the postencephalitic and idiopathic than in the arteriosclerotic type. Biperiden is also commonly used to improve parkinsonian signs and symptoms related to antipsychotic drug therapy. It relieves muscle rigidity, reduces abnormal sweating related with Clozapine and Methadone use and salivation, improves abnormal gait, and to lesser extent, tremor.
