Donepezil is a medication commonly prescribed to treat symptoms of Alzheimer’s disease. It belongs to a class of drugs known as cholinesterase inhibitors, which work by increasing levels of acetylcholine in the brain, a key neurotransmitter involved in memory and cognition. Understanding the correct dosage is crucial for maximizing the therapeutic effects while minimizing potential side effects.
