DESCRIPTION: The product is an alkaloid extracted from the tuberous plant Leucojum aestivum L. from the Amaryllidaceae family. It is manufactured as galanthamine hydrobromide. Galanthamine bromide substance is used in the manufacturing of the medication Nivalin, which is a strong (reversible) cholinesterase inhibitor, increasing the susceptibility of the organism to acetylcholine.
It facilitates the transmission of impulses in neuromuscular synapses and restores neuromuscular transmission. The drug crosses the hematoencephalic barrier and in proper doses facilitates the transmission in the synapses of the central nervous system, and enhances the excitation processes. It enhances the tone of the smooth muscles and intensifies the secretion of the gastric and sweat glands.
Molecular mass: 368.28 (hydrobromide) and 287.36 (base)
