It was found that paroxetine, an inhibitor of CYP2D6, increased the bioavailability of galantamine by 40%. The CYP3A4 inhibitors ketoconazole and erythromycin increased the bioavailability of galantamine by 30% and 12%, respectively. Synthesis
Galantamine is produced from natural resources, but also has many industrial syntheses. Companies such as Janssen, Ortho-McNeil Pharmaceutical, Sanochemia Pharmazeutika, Shire, and Takeda Pharmaceutical Company have industrial processes for synthesizing Galantamine. Research
Organophosphate poisoning
The toxicity of organophosphates results primarily from their action as irreversible inhibitors of acetylcholinesterase. Inhibiting acetylcholinesterase causes an increase in acetylcholine, as the enzyme is no longer available to catalyze its breakdown. In the peripheral nervous system, acetylcholine accumulation can cause an overstimulation of muscarinic receptors followed by a desensitization of nicotinic receptors. This leads to severe skeletal muscle fasciculations (involuntary contractions). The effects on the central nervous system include anxiety, restlessness, confusion, ataxia, tremors, seizures, cardiorespiratory paralysis, and coma. As a reversible acetylcholinesterase inhibitor, galantamine has the potential to serve as an effective organophosphate poisoning treatment by preventing irreversible acetylcholinesterase inhibition. Additionally, galantamine has anticonvulsant properties which may make it even more desirable as an antidote.Research supported in part by the US Army has led to a US patent application for the use of galantamine and/or its derivatives for treatment of organophosphate poisoning. The indications for use of galantamine in the patent application include poisoning by nerve agents "including but not limited to soman, sarin, and VX, tabun, and Novichok agents".
