タクリン·塩酸塩

説明Tacrine is the first therapeutic launched specifically for the treatment of Alzheimer's disease which affects four million people in the US alone. Clinically significant improvement in cognition has been demonstrated in the patients with Alzheimer's disease. Although the cause of Alzheimer's disease is not understood, degeneration of cholinergic neurons is thought to be a primary factor in the development and progression of the disease. Tacrine is a reversible acetylcholinesterase inhibitor that presumably acts centrally by elevating the acetylcholine level in the cerebral cortex and by slowing degradation of acetylcholine from intact cholinergic neurons. While tacrine improves the symptoms of Alzheimer's disease, the underlining cause of the dementing process is not altered. It has also been suggested that the beneficial effects of tacrine may be due to its multiple effects on several neurotransmitter systems.

使用A potent centrally acting anticholinesterase, for therapy of memory deficits in patients with Alzheimers disease. THA also selectively blocks potassium channels in the central nervous system, which results in an increased release of acetylcholi

一般的な説明Tacrine hydrochloride,1,2,3,4-tetrahydro-9-aminoacridine hydrochloride (THA,Cognex), is a reversible cholinesterase inhibitor that hasbeen used in the treatment of Alzheimer disease for severalyears. The drug has been used to increase the levels of AChin these patients on the basis of observations from autopsiesthat concentrations of ChAT and AChE are markedly reducedin the brain, whereas the number of muscarinic receptorsis almost normal. The use of the drug is not withoutcontroversy, as conflicting results on efficacy have been reported.The drug has been used in mild-to-moderateAlzheimer dementia.
