26
AChE Inhibitors: ADRs
- GI: n/v/d - Anorexia and weight loss: - Bradycardia and hypotension - Sleep disturbances: insomnia, vivid dreams - Other cholinergic ADRs as we’ve previously discussed
27
AChE Inhibitors should be avoided in patients that have issues with what things?
should be avoided in patients with baseline issues or known cardiac conduction system disease (meds that can be problematic with this: BB, CCB, anti arrhythmics)
28
Which neurons degenerate to cause AD?
Acetylcholine and glutamate
29
What is the hallmark of dementia? a. Psychosis b. depression c. cognitive decline d. CNS excitation
c. cognitive decline
30
what is most common ADR with AChE inhibitors?
N/V/D
31
If a patient is tolerating an AChE inhibitor, how long would you wait to see if it is effective? a. 1 week b. 1 month c. 2 months d. 6 months
c. 2 MONTHS
32
what is recommended to reserve use for more moderate to severe dementia? a. Memantine b. Donepezil c. Rivastigmine d. Galantamine
Memantine
33
if you are wanting to prescribe AChE Inhibitors, you should Avoid concurrent use of ______.
anticholinergic medications
34
AChE Inhibitors Gradual dose titration should be over _____.
months
35
Factors influencing drug choice for AChE Inhibitors
``` o Cost o Ease of use o Patient tolerability o Safety issues such as DDIs o Provider experience ```
36
what AChE Inhibitors is typically used first line due to fewer DDIs
Rivastigmine: fewer DDIs due to no CYP450 metabolism -->commonly used first line
37
how can you monitor AChE Inhibitors effectiveness?
Use MoCA as well as caregiver impressions of change o Also can use recall of four-word list at 30 seconds and 5 minute along with semantic fluency (e.g., naming as many animals as possible in one minute) o MMSE is not specific enough
38
when pts are on AChE Inhibitors you should have patient Follow-up at ______to assess tolerance and response

this drug blocks nearly all NMDA receptors and is severely psychotoxic
phencyclidine (PCP)
43
Memantine ADRs
o Confusion, agitation, restlessness, hallucinations- May be indistinguishable from AD symptoms o HTN, constipation, HA, cough
44
Recommendations support the management of vascular brain disease and its associated risk factors as part of AD treatment. if vascular brain disease is present, recommend _______ therapy
