Galantamine is a prescribed drug that is also traded under the names of Razadyne, Razadyne ER and Razadyne IR. Galantamine is available in an oral solution, an extended release capsule or a tablet form.
Patients suffering from early onset Alzheimer's disease will benefit from Galantamine therapy as it is proven to elevate acetylcholine levels in the brain, slowing down the impairment to cognitive function that many patients experience. Galantamine is not a cure for Alzheimer's and may not work for long term therapy.
Galantamine works by stopping the brain from consuming a chemical called acetylcholine or ACh by limiting the production of acetylcholinesterase. Acetylcholinesterase is an enzyme that breaks down acetylcholine, which is responsible for many functions in the brain and is one of the first brain chemicals to diminish when a patient experiences the decline from Alzheimer's.
Galantamine has been used for hundreds of years to affect the memory function of the brain. It is a natural substance found in plant life such as various species of the snowdrop plant, the daffodil and certain species of lily. Galantamine is now primarily created in a laboratory for use in humans.
ACh or acetylcholine is a neurotransmitter responsible for many brain functions including memory, movement and bodily functions such as sweating as well as biological functions such as fat consumption. It is one of the first chemicals to diminish when a patient experiences the onset of Alzheimer's disease.
By inhibiting the body from consuming ACh, elevating the level to a more normal status, some of the symptoms of Alzheimer's disease can be diminished with the use of Galantamine.
Alzheimer's is a neurodegenerative disease that gradually worsens over time. One of the earliest signs is the inability to remember things that have happened recently, also known as short term loss of memory. As the chronic condition progresses, it can lead to patients becoming lost in familiar surroundings, mood alterations, deterioration of hygiene and communication problems. Patients often withdraw from loved ones and the outside world. Eventually the patient experiences physical symptoms as their body functions deteriorate and they eventually die of the disease.
Not to be confused with normal age-related memory issues, Alzheimer's can only be detected with extensive testing and medical history evaluation. It is a complicated disease that has no known cure, including Galantamine.
Galantamine works directly on a chemical that is vital to the function of the entire body. In doing so, it may have adverse effects on health that are possibly severe and require attention from professional medical care staff. If you experience the following side effects, get in touch with your doctor right away:
Due to the high rate of memory issues in patients taking Galantamine, it is wise to be aware of the symptoms of overdose in case of double dosing. Both patient and care-giver should be aware of these symptoms and seek immediate emergency medical help as soon as possible:
Other adverse health effects may occur when patients are new to Galantamine and typically disappear with time and adjustment. Your physician may be able to advise you on preventive measures that can be taken to ease these symptoms, so communicate the following if you are experiencing them:
Other adverse effects may be experienced by some patients. If your health changes after being treated with Galantamine, communicate these changes to your physician.
Depending on your overall health and the progression of your condition, your dosage of Galantamine may differ from the general information provided below. Follow your doctor's prescription exactly and do not increase your dosage unless instructed specifically by your health care provider. Do not change the frequency or time of day that you take your dose or doses and do not lengthen the treatment period.
Alzheimer's patients will typically be instructed to take 4 milligrams twice daily, increasing to 8 milligrams for each of two daily doses after a 4 week period, followed by 12 milligrams twice daily after another 4 weeks. Children will have their dosage determined by their physician based on several body and health factors.
Adult Alzheimer's patients are normally instructed to take one 8 milligram capsule with food once per day. This dosage will increase to 16 milligrams daily after 4 weeks followed by 24 milligrams another 4 weeks after that. Use of Galantamine in pediatric patients will be specifically addressed on a case by case basis.
Missing a dose of Galantamine should not cause you to double dose as this will risk overdose symptoms and your overall good health. If you are far enough away from your next dosage, take the missed dose as soon as you remember. If you are close to your next dosage time by the time you realize you've missed a dose, skip it in favor of resuming your regular schedule as soon as possible.
Patients taking capsules that have an extended release mechanism should take them with their breakfast in the morning, taking the capsule whole without breaking, crushing or chewing.
Oral liquid should be taken with the measuring cup, syringe or spoon that was provided with the prescription. Do not use household utensils to measure a dosage, as these items vary greatly.
Your doctor will most likely instruct you to hydrate yourself more with use of this medication, which assists the body in flushing the kidneys by passing more urine, thus avoiding any complications with this medication remaining in your system too long.
Inform your physician if you have ever experienced sensitivity to any other prescription drugs. You will also need to remember to disclose any sensitive reactions you've had to foods, animals, preservatives, dyes or perfumes prior to being treated with Galantamine.

Never share this medication with other people even if they have the same condition as you.
Galantamine is a parasympathomimetic drug that inhibits the production of an enzyme in the brain known as acetylcholinesterase. This enzyme consumes another chemical found in the brain called acetylcholine or ACh, which is important to numerous biological functions including motor skills, memory and digestion. One of the earliest chemicals to diminish in the brain in Alzheimer's sufferers is ACh. By elevating the level of this chemical, Galantamine holds off the dementia symptoms associated with this disease for a period of time. Galantamine is not a cure for dementia or Alzheimer's.
Taken in a gradually increasing dosage that is ramped up every four weeks, Galantamine is available in oral liquid, tablet and time release capsule forms. By taking this medication with the morning meal, patients can better remember their dosage as well as keep a continuous amount of the drug in their system, which helps Galantamine be more effective against symptoms.
Adverse effects on health may include stomach upsets including gas, bloating, nausea, or diarrhea and vomiting. Fainting spells, sluggish heart rhythm or trouble urinating are more serious effects as are showing signs of blood in stool, vomit or urine. Any symptoms such as these should be reported to your physician right away. Seek emergency assistance if you or the patient under your care shows any signs of overdose or shock while taking Galantamine.
Pediatric patients, women who are pregnant and women who are breastfeeding should not be prescribed this drug for safety reasons unless their physician has discussed the possible risks faced to these groups prior to prescribing Galantamine.
Avoid taking any other medications when you are on a prescription dose of Galantamine including those found over the counter and at the health food store. Inform your physician of all medications you are taking, any hypersensitive reactions you've experienced in the past and your health history. Patients with diseases of the heart, kidney or liver or those who have stomach or bowel conditions may not be safe in taking Galantamine. Inform all health professionals who have care of you that you are on this medication for your own safety.
