Galantamine
About Galantamine
Galantamine belongs to a group of medicines called 'anti-dementia agents' used to treat mild to moderate dementia caused by Alzheimer's disease. Alzheimer's disease is a neurological disorder, which causes dementia (memory loss), and slowly destroys the ability to think, learn, communicate, and handling daily activities. Dementia is a condition associated with impairment in memory, communication and thinking.
Galantamine contains 'Galantamine' that belongs to the class of 'Acetylcholinesterase Inhibitors'. Galantamine blocks the action of the enzyme cholinesterase, an enzyme that breaks down acetylcholine. Acetylcholine is a neurotransmitter or a chemical messenger that transmits the message from one nerve cell to another nerve cell, muscle cell, or gland cell. Galantamine thus increases acetylcholine levels allowing the nerve cells to communicate. It restores the balance of neurotransmitters and thus improves mental function, such as memory and thinking.
Your doctor will decide the dose and duration based on your disease's severity and response to treatment. Common side effects of Galantamine include nausea, vomiting, diarrhoea, headache, dizziness, drowsiness, shakiness (tremor), weakness, depression, and loss of appetite. These side effects are not familiar to everyone and vary individually. If you notice any side effects that are not manageable, please consult your doctor.
Please tell your doctor if you are allergic to Galantamine or its components. If you are using any prescription and non-prescription medications, let your doctor know before starting Galantamine. Inform your doctor beforehand if you have a history of liver or kidney diseases, heart problems, electrolyte imbalance, stomach ulcer, fits, Parkinson’s disease, breathing disorders, and urination problems. If you had recent surgery on the stomach, intestines or bladder, tell your doctor. If you are pregnant, planning to conceive or a breastfeeding mother, inform your doctor before starting Galantamine. Avoid consuming alcohol along with Galantamine as it can make you dizzy or drowsy.
Uses of Galantamine
Medicinal Benefits
Galantamine treats mild to moderate dementia caused by Alzheimer's disease. It contains 'Galantamine', an acetylcholinesterase inhibitor. Galantamine increases acetylcholine (a brain chemical) levels in the central nervous system by blocking the action of the cholinesterase enzyme. This process helps in transmitting nerve signals that play an essential role in memory. Galantamine is not a cure for Alzheimer's disease but improves memory, thinking awareness and the ability to perform daily functions.

Disease/Condition Glossary
Alzheimer's disease: The disease is named after Dr Alois Alzheimer, who was the first to discover the disease. Alzheimer's disease is a neurological disorder that causes dementia (memory loss), and slowly destroys the ability to think, learn, communicate, and eventually, the ability to handle daily activities. It is the most common cause of dementia (memory loss) in adults.
Dementia is the loss of cognitive functioning, such as remembering, thinking, and reasoning. The causes of this disease are abnormal functioning of brain cells which cause a disturbance in communication between them. The risk factors are age, family history and genetics of a person. Alzheimer's disease symptoms include memory loss, trouble with familiar tasks, difficulties with problem-solving, trouble with writing or talking, disorientation, problems with reasoning or judgment, mood and personality changes. In most people, the symptoms of Alzheimer's appear in their mid-60's.
