Rivastigmine is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of the Alzheimer's type and dementia due to Parkinson's disease.
The drug can be administered orally or via a transdermal patch; the latter form reduces
the prevalence of side effects, which typically include nausea and vomiting. The drug is eliminated through the urine, and appears to have relatively few drug-drug interactions.
