Overview
Galanthamine Hydrobromide is a tertiary alkaloid derived from plants like Galanthus woronowii. It is widely recognized for its acetylcholinesterase inhibitory properties, making it a key compound in treating neurodegenerative diseases. The compound is synthesized or extracted for pharmaceutical use, often in tablet or injectable forms. Its discovery dates back to the 1950s, and it has since been approved by regulatory bodies like the FDA for Alzheimer's treatment. The drug works by increasing acetylcholine levels in the brain, thereby improving memory and cognitive functions.
Physical and Chemical Properties
Galanthamine Hydrobromide appears as a white to off-white crystalline powder with a molecular weight of 368.27 g/mol. It is soluble in water and slightly soluble in ethanol, with a melting point around 258-260°C, where it decomposes. The compound is stable under recommended storage conditions but should be protected from light and moisture. Its solubility profile makes it suitable for formulation into oral and injectable medications. The hydrobromide salt form enhances its stability and bioavailability compared to the free base.
Main Applications
The primary application of Galanthamine Hydrobromide is in the treatment of mild to moderate Alzheimer's disease. It is also used off-label for other cognitive impairments, such as vascular dementia and traumatic brain injury. In addition to its neurological benefits, research is exploring its potential in treating nicotine addiction and myasthenia gravis. The compound's ability to modulate cholinergic neurotransmission underpins its therapeutic effects, making it a versatile agent in neurology and psychiatry.
Safety and Storage
Galanthamine Hydrobromide should be handled with care to avoid inhalation or skin contact. Personal protective equipment, including gloves and goggles, is recommended during handling. The compound is generally safe when used as prescribed but may cause side effects like nausea or dizziness. Storage should be in a cool, dry place, preferably at room temperature, and protected from light. Bulk quantities should be sealed in airtight containers to prevent moisture absorption and degradation. Proper disposal methods should be followed to avoid environmental contamination.
B2B Procurement Guide
When procuring Galanthamine Hydrobromide, prioritize suppliers with certified Good Manufacturing Practice (GMP) compliance. Request a Certificate of Analysis (COA) to verify purity, typically ≥98% for pharmaceutical use. Batch testing for heavy metals and residual solvents is also critical. Price varies based on quantity and purity, with bulk purchases often discounted. Lead times can be significant due to stringent quality controls, so plan procurement well in advance. Consider suppliers with a track record in pharmaceutical raw materials to ensure reliability and regulatory adherence.
