Monitoring Parameters
Monitor IOP.
Symptoms: Mydriasis, dryness of mucous membranes, flushing, increased heart rate, decreased bowel motility, decreased ureter and bladder tone, increased temperature, excitation, confusion, clouding of consciousness and/or hallucinations. In severe cases, cardiac and respiratory depression may occur. Management: Supportive treatment. Gastric lavage or emesis may be considered. Acetylcholinesterase inhibitors may be given as antidote. Closely monitor vital signs. Fever reduction, application of catheter, and artificial ventilation may be needed. Cardiac stimulant (e.g. dobutamine) may be considered in case of cardiac depression.
Drug Interactions
Enhanced CNS and peripheral adverse effects with other anticholinergic psychotropic drugs, antihistamines, antispasmodics, and other antiparkinsonian agents. May potentiate anticholinergic effect (especially AV conduction) with quinidine. May enhance dyskinesia with levodopa. Reduced effect of metoclopramide and other compounds with similar activity on the gastrointestinal tract.
Food Interaction
Alcohol may enhance the adverse effects of biperiden.
Mechanism of Action: Biperiden is a predominantly central anticholinergic agent that helps balance cholinergic transmission in the basal ganglia. It has weak peripheral anticholinergic activity.
Absorption: Readily absorbed from the gastrointestinal tract. Bioavailability: Approx 30%. Time to peak plasma concentration: 0.8-1.6 hours.
Distribution: Plasma protein binding: 90-95%.
Metabolism: Undergoes extensive first-pass metabolism; metabolised via hydroxylation of bicycloheptene ring and piperidine ring.
Excretion: Elimination half-life: Approx 20 hours.
