Cholinesterase Inhibitors


The Aricept-type drugs (including Razadyne and Excelon) are not memory enhancement medications. Their improvement in memory function is modest, about 1.5%. However, these drugs appear to help folks better retain Activities of Daily Living (ADLs). The average patient on Razadyne stays our of a nursing home for 20 months longer than an untreated patient. Here's a Table for Razadyne (formerly called Reminyl) showing a brief improvement on testing with a slowed decline over a year; in effect the moderate dementia measured on this test stabilized for a year:

These drugs are expensive, running about $375 per month, although Aricept is now available as a generic–donepezil which can be found at $16 on for a month’s supply online. There are side effects, most often dizziness and lower GI distress in about 10-20% of patients. These side effects are often eliminated by switching among the three drugs. Excelon comes in a patch application which often alleviates all side effects.



Glutamate Inhibition
Namenda, previously described, costs around $400 per month, but is now available as a generic–memantine is used twice per day and costs about $45 for a month’s supply. It's used as an anti-inflammatory agent that is, hopefully, neuroprotective. This is still theoretical, but as it has few side effects the drug is thought worthwhile.
