Donepezil

Donepezil is a medication that helps treat dementia (memory loss and mental changes) as a result of mild, moderate or severe Alzheimer’s disease. It’s approved by Food and Drug Administration for medical use in the US since 1996.  It’s one of the most prescribed medications in the US. However, Donepezil won’t cure Alzheimer’s disease. It only helps slows down the progression of the disease. This drug helps improve awareness, memory and the ability of patients with Alzheimer’s disease to function.

Alzheimer’s disease is a progressive disorder that causes the brain cells to degenerate and eventually die. It’s the most common type of dementia- a continuous decline in behavior, thinking and social skills that disrupts the patient’s ability to function well.  Alzheimer’s disease affects over half of all patients with dementia. It tends to progress, deteriorate and lead to death within 7 to 10 years. The progress of this disease varies from individual. It may progress slowly over many years for some patients while it may progress rapidly for others. Early signs of this disease includes forgetting recent conversations or events. As it progresses, patients with this disease will develop severe memory impairment and lose the ability to carry out the daily task. There is no current cure for Alzheimer’s disease but there are medications available to help slow down its progression.

Donepezil is a type of acetylcholinesterase inhibitor.  It is an enzyme blocker that works by breaking down the neurotransmitter in the brain called acetylcholine. Neurotransmitters are involved in transmitting messages between nerve cells. The nerve cells in the brain continuously release acetylcholine. In Alzheimer’s disease, the level of acetylcholine is lower than the normal due to the degeneration of the brain cells.  

Donepezil increases the acetylcholine level in the brain by preventing the action of acetylcholinesterase. Preventing the action of this enzyme slows down the breakdown of acetylcholine that is being released from the remaining undamaged nerve cells in the brain. As a result, the level of acetylcholine is increased which helps improve the cognitive process of learning, thinking , memory and also improving dementia symptoms and every function of patients with Alzheimer’s disease.

How to Use It

Your dose is based on your condition and the severity of your condition. Donepezil comes in a tablet form that you need to take by mouth.

Mild to moderate Alzheimer’s disease: The typical starting dose is 5 mg tablet once a day. Take it before bedtime to reduce the risk of side effects such as nausea and diarrhea. After four to six weeks, your doctor will increase your dose to 10 mg a day taken before bedtime.

Take your medication exactly as prescribed by your physician. You may take it with or without food. Swallow the tablet whole with plenty of water. For a missed dose, leave out that dose and take your next dose the following bedtime. If you failed to take the tablet for a week or more, contact your physician before you take any more medication.
