毒理性
苯海索是一种选择性的M1毒蕈碱型乙酰胆碱受体拮抗剂。它能够区分M1(皮层或神经元)和周围毒蕈碱亚型(心脏和腺体)。苯海索部分阻断中枢神经系统中的胆碱能活动,这种活动是帕金森病症状的原因。它还被认为能够增加多巴胺的可用性,多巴胺是一种在大脑中至关重要的化学物质,对于自主肌肉运动的发起和顺畅控制非常重要。
Benztropine is a selective M1 muscarinic acetylcholine receptor antagonist. It is able to discriminate between the M1 (cortical or neuronal) and the peripheral muscarinic subtypes (cardiac and glandular). Benztropine partially blocks cholinergic activity in the CNS, which is responsible for the symptoms of Parkinson's disease. It is also thought to increase the availability of dopamine, a brain chemical that is critical in the initiation and smooth control of voluntary muscle movement.
