👩🏽⚕️ Additional questions (FAQs)
💬 Galantamine (Galantamine / Razadyne) tablets/capsules are a medicine for which disease?
This is a very important and important pill given to patients in the early and middle stages of Alzheimer's Disease, which occurs when they get older, where their memory is completely gone and they don't understand anything else around them! This cannot cure the patient immediately/rejuvenate the brain, but this medicine greatly reduces the rate of loss of memory (Cognitive function) and helps the patient do their job.
💬 How does this drug (Galantamine) help Alzheimer's patients maintain memory?
The chemical messenger 'Acetylcholine' is essential for our brain to maintain memory, learning, and thinking. In the brains of Alzheimer's patients, these are destroyed/depleted very quickly. After taking this medicine (Cholinesterase inhibitor), the enzyme that breaks down that chemical is blocked, allowing more acetylcholine to accumulate in the brain. Then, the nerves in the brain can communicate with each other/renew memories again.
💬 What are the possible side effects of taking this medicine?
Since this chemical attacks the brain as well as the intestines, drinking it can definitely cause 'severe nausea/vomiting, stomach cramps, anorexia, and persistent diarrhea' (so start with a small dose first). Also, in the elderly, it can cause sudden 'bradycardia' and dizziness, which can lead to falls.
