Also Known As: Tacrine, Cognex

Tacrine was the prototypical cholinesterase inhibitor for the treatment of Alzheimer's disease. Studies found that it may have a small beneficial effect on cognition and other clinical measures, though study data was limited and the clinical relevance of these findings was unclear.[1][2]

The use of tacrine is limited by poor oral bioavailability, the necessity for four-times daily dosing, and considerable adverse drug reactions (including nausea, diarrhea, urinary incontinence and hepatotoxicity) such that few patients could tolerate therapeutic doses.[3]

Newer cholinesterase inhibitors, such as donepezil, are now preferred over tacrine.
