Interaction Details
Rivastigmine is classified as belonging to the following category: Acetylcholinesterase (Ache) Inhibitors
Evidence from in vitro research suggests that clubmoss extract can inhibit acetylcholinesterase activity. Theoretically, concurrent use of clubmoss with other acetylcholinesterase (AChE) inhibitors might have additive effects and increase the risk of cholinergic side effects. AChE inhibitors and cholinergic drugs include bethanechol (Urecholine), donepezil (Aricept), echothiophate (Phospholine Iodide), edrophonium (Enlon, Reversol, Tensilon), neostigmine (Prostigmin), physostigmine (Antilirium), pyridostigmine (Mestinon, Regonol), succinylcholine (Anectine, Quelicin), and tacrine (Cognex).

Clubmoss Overview

Rivastigmine Overview
-
Rivastigmine is used to treat dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and may cause changes in mood and personality) in people with Alzheimer's disease (a brain disease that slowly destroys the memory and ability to think, learn, communicate and handle daily activities). Rivastigmine is also used to treat dementia in people with Parkinson's disease (a brain and nervous system disease with symptoms of slowing of movement, muscle weakness, shuffling walk, and loss of memory). Rivastigmine is in a class of medications called cholinesterase inhibitors. It improves mental function (such as memory and thinking) by increasing the amount of a certain natural substance in the brain.
