Biperiden, sold under the brandname Akineton among others, is a medication used to treat Parkinson disease and certain drug-induced movement disorders.[1] It is not recommended for tardive dyskinesias.[2] It is taken by mouth, injection into a vein, or muscle.[1][2]

Common side effects include blurred vision, dry mouth, sleepiness, constipation, and confusion. It should not be used in people with a bowel obstruction or glaucoma.[1] It is unclear if use in pregnancy or breastfeeding is safe.[3] Biperiden is in the anticholinergic family of medication.[1]

Biperiden was approved for medical use in the United States in 1959.[1] It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.[4] The wholesale cost in the developing world is about 1.52 to 12.92 USD per month.[5] In the United States it costs about 50 to 100 USD per month.[6]

Medical uses

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, such as akathisia.

It relieves muscle rigidity, reduces abnormal sweating related with clozapine and methadone use[7][8] and salivation, improves abnormal gait, and to lesser extent, tremor.

In its role as a synthetic acetylcholine antagonist, biperiden has been analyzed as an alternative anticonvulsant for usage in the treatment of intoxication by organophosphorus nerve agents, such as sarin.[9]

Pregnancy and lactation

Children

Children and adolescents aged 1 year and older may be treated. The clinical experience is mainly on the short-term treatment of acute drug induced dystonic reactions. Doses should be reduced according to the weight of the patients.

Contraindications

Side effects

Dose-dependent side effects are frequent. Particularly geriatric patients may react with confusional states or develop delirium.

Interactions

Overdose

Biperiden mimics an atropine intoxication with mydriasis, dryness of mucous membranes, red face, atonic states of bowels and bladder, and hyperthermia in high doses. Central consequences are agitation, confusion, and hallucinations. An untreated overdose may be fatal, particular in children. Premortal signs are respiratory depression and cardiac arrest. A specific antagonist is physostigmine which combines a peripheral and a central action. Carbachol can be used to treat atonic bowels and bladder. The vital functions should be monitored and stabilized. It may be necessary to treat hyperthermia with cooling blankets.

Pharmacokinetics

The oral bioavailability is only 33 ± 5% due to extensive first-pass metabolism. In young, healthy volunteers, peak plasma concentrations following a single oral 4 mg immediate-release dose are reached after 1.5 hours. The elimination half-life has been determined as 18.4 hours, and may be prolonged in geriatric patients. After a 4 mg intravenous dose, the elimination half-life is approximately 24 hours.

Pharmacology

Biperiden has an atropine-like blocking effect on all peripheral structures which are parasympathetic-innervated (e.g. cardiovascular and visceral organs). It also has a prominent central blocking effect on M1 receptors. Biperiden does also act as FIASMA (functional inhibitor of acid sphingomyelinase).[11]

History

Biperiden was synthesized by the German chemist W. Klavehn from Knoll AG, Germany. In March 1953 a patent was applied for in Germany[12] and subsequently in many other countries. A US patent application was filed in March 1954 and granted in April 1957.[13]

One website reported that it was not commercially available in the United States as of 2017.[14]
