Management: Supportive treatment. Gastric lavage or emesis may be considered. May give acetylcholinesterase inhibitor as an antidote. Artificial ventilation, reduction of fever and application of a bladder emptying catheter may be necessary. May administer a cardiac stimulant (e.g. dobutamine) if cardiac depression occurs.
Drug Interactions
Increased CNS and peripheral side effects w/ anticholinergic psychotropic drugs, antihistamines, other antiparkinsonian drugs and antispasmodics. May potentiate dyskinesia w/ levodopa.

Action
Description: Biperiden is an anticholinergic agent w/ marked effect on the CNS which is important for its therapeutic application and has weak peripheral vegetative effects. The mechanism of action is considered to relate to competitive antagonism of acetylcholine at cholinergic receptors in the corpus striatum, which then restores the balance.
