Aricept is the trade name for donepezil, a drug indicated to treat Alzheimer's disease. It is an acetylcholinesterase inhibitor that works by preventing the breakdown of a neurotransmitter called acetylcholine, found in the brain. Aricept is only suitable for people with mild-to-moderate Alzheimer's disease. According to the Alzheimer's Society, Alzheimer's drugs can not cure the disease. However, drugs can improve symptoms and slow down disease progression. The Alzheimer's Society notes that 40 to 60 percent of Alzheimer's patients may benefit from treatment with acetylcholinesterase inhibitor treatment. There are several other drug treatments for Alzheimer's disease.
Exelon
Exelon, also known by the generic name, rivastigmine, is an acetylcholinesterase inhibitor indicated to treat Alzheimer's disease. It works in the same way as Aricept. Exelon is only suitable for people with mild-to-moderate Alzheimer's disease. It is supplied as a dermal patch, in capsules and as a liquid. According to the Fisher Center for Alzheimer's Research Foundation, approximately 50 percent of patients who try Exelon experience a slight improvement in their condition. Exelon may not be suitable for patients with sick sinus syndrome, an enlarged prostate, asthma or epilepsy. Side effects may include an upset stomach, weight loss and joint pain, according to Drugs.com.
Razadyne
Razadyne is the trade name for galantamine, an acetylcholinesterase inhibitor. According to the Alzheimer's Society, it was originally derived from snowdrops and narcissi flowers. It is supplied in extended-release capsules, immediate-release tablets and as a liquid to be taken orally. Razadyne may not be suitable for patients with heart disease, asthma, epilepsy and kidney or liver disease. Razadyne may impair reaction times so care should be taken if driving. Common side effects may include weight loss, headche, nausea and dizziness, according to RxList.
Namenda
Namenda, also known by the generic name, memantine, is amN-methyl D-aspartate receptor antagonist. It is indicated to treat moderate-to-severe Alzheimer's disease. According to the National Institute on Aging, it works by regulating levels of the brain chemical known as gluatamate. Namenda is not a cure for Alzheimer's disease but it may help a patient to cope with certain daily activities such as using the bathroom, for longer. Common side effects may include confusion, dizziness, constipation and headache, notes the National Institute on Aging.
