the cognitive changes addressed through medication include memory, communication, ability to perform daily activities, and awareness.
donepezil (aricept)
donepezil is a cholinesterase inhibitor. these drugs work by preventing the breakdown of the neurotransmitters acetylcholine and butyrylcholine. these neurotransmitters play a role in cognitive ability, such as memory, learning, attention and arousal, and increase communication between nerve cells. the drug is used in alzheimer’s to help slow cognitive decline.
donepezil is available as oral tablets and should be taken daily. depending on the type prescribed, the tablets can be swallowed whole or placed under the tongue to dissolve.
the dosage will depend on the person, but people typically start off at a low dosage of 5 mg per day, with increases happening after four to six weeks and then again in three or more months.
the drug can be increased in increments starting at 5 mg per day, then 10 mg per day, and then again to a maximum dosage of 23 mg per day. those with mild to moderate alzheimer’s disease will likely be kept at the lower dosage of 10 mg per day, whereas those with severe alzheimer’s disease will be given the higher dosage of 23 mg per day. donepezil should be taken at night before bedtime, with or without food.
