Rivastigmin er en acetyl - og butyrylkolinesterasehæmmer af carbamattypen, som menes at lette kolinerg neurotransmission ved at nedsætte nedbrydningen af acetylkolin, som er frigjort af funktionelt intakte kolinerge neuroner.
Rivastigmine is an acetyl- and butyrylcholinesterase inhibitor of the carbamate type, thought to facilitate cholinergic neurotransmission by slowing the degradation of acetylcholine released by functionally intact cholinergic neurones.
