Guideline Consensus for Cholinesterase Inhibs :
1. Modest benefit for ___ in mild -severe AD
2. Does not alter what ?
3. Higher doses dont necesarily offer?
4. Discontinuation may

3. Discontinuation is not associated with ?
4. ORAL IR TAB DOSE? ER TAB?
5. DOse adjust for CrCL < 30 ?
6. IR doses > 5 mg/day often ?
7. Food considerations
- Stop excess NMDA receptor activation –> less glutamate
- Dizzy, HA, Confusion and GI upset
- Signif worsening of cognition
- IR 5mg everyday for a week –> titrate by 5mg to max 10mg BID , ER 7mg everyday , max 28mg qdaily
- IR target 5mg BID , ER target 14mg everyday

- 2024
- meaningful , 18 months
