| Description | A muscarinic antagonist that has effects in both the central and peripheral nervous systems. It has been used in the treatment of arteriosclerotic, idiopathic, and postencephalitic parkinsonism. It has also been used to alleviate extrapyramidal symptoms induced by phenothiazine derivatives and reserpine. [PubChem] |

| Indication | For use as an adjunct in the therapy of all forms of parkinsonism and control of extrapyramidal disorders secondary to neuroleptic drug therapy. | ||||||||||||||||||||||||||||||||||||
| Pharmacodynamics | Biperiden is a weak peripheral anticholinergic agent. It has, therefore, some antisecretory, antispasmodic and mydriatic effects. In addition, biperiden possesses nicotinolytic activity. The parenteral form of biperiden is an effective and reliable agent for the treatment of acute episodes of extrapyramidal disturbances sometimes seen during treatment with neuroleptic agents. Akathisia, akinesia, dyskinetic tremors, rigor, oculogyric crisis, spasmodic torticollis, and profuse sweating are markedly reduced or eliminated. With parenteral biperiden, these drug-induced disturbances are rapidly brought under control. | ||||||||||||||||||||||||||||||||||||
| Mechanism of action | Parkinsonism is thought to result from an imbalance between the excitatory (cholinergic) and inhibitory (dopaminergic) systems in the corpus striatum. The mechanism of action of centrally active anticholinergic drugs such as biperiden is considered to relate to competitive antagonism of acetylcholine at cholinergic receptors in the corpus striatum, which then restores the balance. | ||||||||||||||||||||||||||||||||||||

1. Muscarinic acetylcholine receptor M1 Pharmacological action: yesActions: antagonist The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover Organism class: humanUniProt ID: P11229 ![]() Gene: CHRM1 ![]() Protein Sequence: FASTA Gene Sequence: FASTA SNPs: SNPJam Report ![]() References:
2. Neuronal acetylcholine receptor subunit alpha-2 Pharmacological action: yesActions: antagonist After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane Organism class: humanUniProt ID: Q15822 ![]() Gene: CHRNA2 ![]() Protein Sequence: FASTA Gene Sequence: FASTA SNPs: SNPJam Report ![]() References: |
