腹腔注射卡巴拉汀(S-卡巴拉汀;0.5-2.5 mg/kg;在测试前 60 分钟给药)可显着且剂量依赖性地减轻铝引起的行为异常[4]。在患有急性结肠炎、体重为 200-250 克的 BALB/c OlaHsd 雄性 8-9 周龄小鼠中,卡巴拉汀(0.5、1 mg/kg/天;皮下注射;持续 8 天)可使 IL-6 浓度降低约 50% 和 60%分别是,但不是 TNF-α 和 IL-1β 浓度 [3]。 1 mg/kg 的卡巴拉汀可完全止血并抑制结肠收缩,但 0.5 mg/kg 的剂量则不然。虽然卡巴拉汀 (1 mg/kg) 可减少粘膜下水肿和细胞浸润,但卡巴拉汀 (0.5 mg/kg) 治疗显示这些病理结果的变化最小。此外,还观察到了地穴结构的部分恢复。试验结束时,卡巴拉汀 (1 mg/kg) 使体重减轻了 4.7% [3]。

药代性质 (ADME/PK) |
Absorption, Distribution and Excretion
Rivastigmine is extensively metabolized primarily via cholinesterase-mediated hydrolysis to the decarbamylated metabolite NAP226-90. Renal excretion of the metabolites is the major route of elimination. Less than 1% of the administered dose is excreted in the feces. 1.8 to 2.7 L/kg renal cl=2.1-2.8 L/hr Metabolism / Metabolites Rivastigmine is rapidly metabolized by cholinesterase-mediated hydrolysis. Biological Half-Life 1.5 hours |
毒性/毒理 (Toxicokinetics/TK) |
Hepatotoxicity
In large placebo controlled trials, rivastigmine therapy was not associated with an increased rate of serum enzyme elevations compared to placebo treatment and no instances of clinically apparent liver injury with jaundice were reported. Nevertheless, since its introduction into clinical use, rivastigmine (administered by transdermal patch) has been implicated in at least one report of clinically apparent hepatotoxicity with mild jaundice. The time to onset was 2 months and the serum enzyme elevations had a mildly hepatocellular pattern. Mild rash and eosinophilia were also present, but autoimmune features were not. Recovery was complete within 5 weeks of drug discontinuation. Likelihood score: D (possible, rare cause of clinically apparent drug-induced liver injury). Protein Binding 40% |

其他信息 |
Rivastigmine is a carbamate ester obtained by formal condensation of the carboxy group of ethyl(methyl)carbamic acid with the phenolic OH group of 3-[(1S)-1-(dimethylamino)ethyl]phenol. A reversible cholinesterase inhibitor. It has a role as an EC 3.1.1.8 (cholinesterase) inhibitor, a neuroprotective agent and a cholinergic drug. It is a carbamate ester and a tertiary amino compound. It is a conjugate base of a rivastigmine(1+).
Rivastigmine is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of the Alzheimer's type. Rivastigmine is a cholinesterase inhibitor that inhibits both butyrylcholinesterase and acetylcholinesterase. Rivastigmine is a Cholinesterase Inhibitor. The mechanism of action of rivastigmine is as a Cholinesterase Inhibitor. Rivastigmine is an oral acetylcholinesterase inhibitor used for therapy of Alzheimer disease. Rivastigmine is associated with a minimal rate of serum enzyme elevations during therapy and is a rare cause of clinically apparent liver injury. A carbamate-derived reversible CHOLINESTERASE INHIBITOR that is selective for the CENTRAL NERVOUS SYSTEM and is used for the treatment of DEMENTIA in ALZHEIMER DISEASE and PARKINSON DISEASE.

Treatment of dementia Treatment of dementia Mechanism of Action Rivastigmine is a carbamate derivative that is structurally related to physostigmine, but not to donepezil and tacrine. The precise mechanism of rivastigmine has not been fully determined, but it is suggested that rivastigmine binds reversibly with and inactivates chlolinesterase (eg. acetylcholinesterase, butyrylcholinesterase), preventing the hydrolysis of acetycholine, and thus leading to an increased concentration of acetylcholine at cholinergic synapses. The anticholinesterase activity of rivastigmine is relatively specific for brain acetylcholinesterase and butyrylcholinesterase compared with those in peripheral tissues. Pharmacodynamics Rivastigmine is a parasympathomimetic and a reversible cholinesterase inhibitor. An early pathophysiological feature of Alzheimer's disease that is associated with memory loss and cognitive deficits is a deficiency of acetylcholine as a result of selective loss of cholinergic neurons in the cerebral cortex, nucleus basalis, and hippocampus. Tacrine is postulated to exert its therapeutic effect by enhancing cholinergic function. While the precise mechanism of rivastigmine's action is unknown, it is postulated to exert its therapeutic effect by enhancing cholinergic function. This is accomplished by increasing the concentration of acetylcholine through reversible inhibition of its hydrolysis by cholinesterase. If this proposed mechanism is correct, rivastigmine's effect may lessen as the disease progresses and fewer cholinergic neurons remain functionally intact. |
