Rivastigmine tartrate Chemical Properties,Uses,Production
Pharmacological effects
Rivastigmine tartrate is rivastigmine Alzheimer's disease drugs, rivastigmine is physostigmine derivative by Novartis for the first time successfully developed the trade name Exelon (exelon), a molecule with there carbamate structure, is a kind of amino acid of selective cerebral cholinesterase inhibitor, can also inhibit the acetylcholinesterase and butyrylcholinesterase, cholinergic neurons by delaying the release of acetylcholine degradation and energy promoting cholinergic nerve conduction, can improve cognitive function disorders mediated by cholinergic, thereby improving the cognitive function of Alzheimer's disease patients. Rivastigmine plasma protein binding is weak, easily through the blood-brain barrier, which has a high degree of brain selectivity. It not only selectively acts on the most easily affected cerebral cortex and hippocampus, but also preferentially inhibits the dominant subtype of AChE in the brain, resulting in a reduction in the efficacy of peripheral cholinergic side effects. Rivastigmine in vivo half-life is short and long duration of action. Unlike tacrine, this product in the hippocampus and cortex of G1 enzyme inhibitory effect is stronger. Clinic for the treatment of mild to moderate Alzheimer-type dementia, or Alzheimer's disease can be suspected Alzheimer's disease clinically.
Alzheimerdisease
Alzheimer's disease (Alzheimerdisease, AD) is a kind of onset hidden attack the development of dementia, clinical with memory disorders, aphasia, apraxia, agnosia, executive function and cognitive impairment features. At the same time, that is accompanied by the psychological and behavioral abnormalities and obvious function of social life decline. AD duration course is 3 to 7 years, after the onset of a small number of patients can survive for more than 10 years or longer. In 1906, German neurologist Alzheimer first reported one case of 51-year-old female patient, brain autopsy found that age spots, he added that the disease has been reported neurofibrillary changes. Kraepelin (1913) would be named the disease of Alzheimer's disease. Thought that the disease is only found in pre-elderly, it is also known as Alzheimer's (preseniledementia). Later found brain senile dementia (seniledementia) and even the health of the elderly also have the same AD pathology, only a difference in degree. In the 1970s, the US National Institute of Gerontology Research Institute (NIA), the National neurology, language barriers and Stroke Research Institute (NINCDS) and the National Institute of Mental Health (NIMH) unified on senile dementia and AD mutual understanding of the relationship, in addition to age sooner than thought, both clinical symptoms and pathological brain changes were not significantly different, the Department of the same disease. Although the incidence of pre-elderly has been proposed, said AD2 type, is equivalent to the previous Alzheimer's disease, old age of AD1 type, the equivalent to senile dementia, but in the new diagnostic classification of literature in general, the onset before the age of 65 said early-onset AD, after 65 years, the onset of said late onset AD; in families predisposed called familial AD (FAD), said that no family predisposed sporadic AD.
Pharmacokinetics
Absorption: Rivastigmine completely absorbed quickly. About 1 hour to reach the peak plasma concentration. Because interacts with the target enzyme, biological drugs increase using more than the increased dose is expected values of about 1.5 times. The absolute bioavailability of taking 3 mg is about 36%. Rivastigmine with food can be allowed to absorb Tmax an extra 90 minutes to reduce the Cmax, AUC increased nearly 30%.
Distribution: the binding capacity of Rivastigmine with plasma protein is weak (approximately 40%). It easily passes the blood-brain barrier, surface volume of distribution is 1.8~2.7L/kg.
Metabolism: Rivastigmine mainly goes through cholinesterase mediated hydrolysis and rapid, extensive metabolism (plasma half-life of about 1 hour). In vitro experiment results show that this metabolite only a weak cholinesterase inhibition (<10%). In vitro and animal experimental results show that the majority of the cytochrome P450 isoenzymes are rarely involved in rivastigmine hydrogen tartrate metabolism. In vivo experiments also confirmed the bitartrate.
Excretion: In urine, it is not found rivastigmine hydrogen tartrate prototype drug. The main metabolites excreted through the kidneys. 14C isotope labeled rivastigmine hydrogen tartrate administered within 24 hours, most rapidly excreted by the kidneys (> 90%) and only <1% of the drug excreted in the faeces. Alzheimer's disease patients have no body weight Rivastigmine or a metabolite accumulation.
Elderly subjects: Despite the elderly Rivastigmine biological utilization degree is higher than that of healthy young volunteers, but after 50 to 92 years in patients with Alzheimer test results showed that the bioavailability does not change with increasing age.

Indications
Used to treat the symptoms of mild to moderate Alzheimer's disease dementia symptoms.
Side effects
The most commonly reported adverse drug reactions were gastrointestinal reactions,, including nausea (38%), vomiting (23%), especially in the dosage of the more obvious. In clinical trials,it found that women were more prone to gastrointestinal reactions and weight loss.
The following table lists the adverse reactions of this product, including clinical trials and post-marketing reports of all cumulative.

Above Pictured: The common adverse reactions of Rivastigmine in various body systems table.
The frequency of adverse reactions were follows conversion: very common (>=1/10), common (>=1/100, <1/10), occasionally (>=1/1 000, <1/100), rare (>=1/10000, <1/1 000), very rare (<1/10000), including case reports.
In addition, the following side effects in patients taking Exelon in patients with the occurrence rate of at least a given placebo 2%, increased sweating, general malaise, weight loss, tremor. Female patients with nausea, vomiting, loss of appetite and weight loss are more sensitive. Exelon does not cause changes in any laboratory examinations, including liver function, or electrocardiogram, and there is no need special care.
There is a case of patients taking this product, while the joint use of several other drugs, the emergence of Stevense-Johnson syndrome.
