Exelon is FDA-approved for treating mild to moderate dementia associated with Alzheimer's disease and dementia associated with Parkinson's disease. It helps manage symptoms such as memory loss, confusion, and reasoning difficulties, though it does not cure the underlying diseases.
Exelon belongs to a class of drugs called cholinesterase inhibitors. It works by blocking enzymes (acetylcholinesterase and butyrylcholinesterase) that break down acetylcholine in the brain. By preventing this breakdown, more acetylcholine remains available to help nerve cells communicate, potentially improving cognitive function and daily living abilities.
Exelon is typically started at a low dose and gradually increased to reduce side effects like nausea, vomiting, loss of appetite, and diarrhea. It should not be stopped abruptly, as this may worsen dementia symptoms. The transdermal patch may cause skin irritation. Patients should inform their doctor of any heart conditions, stomach ulcers, urinary problems, or seizures before starting treatment. Regular monitoring of weight is recommended during therapy.
