Benzgalantamine, sold under the brand name Zunveyl, is a medication used for the treatment of mild to moderate dementia of the Alzheimer’s type.^[1] It is a cholinesterase inhibitor.^[1] Benzgalantamine is a prodrug of galantamine.^[1]

The most common side effects include nausea, vomiting, diarrhea, dizziness, headache, and decreased appetite.^[1]

Benzgalantamine was approved for medical use in the United States in July 2024.^[1][2][3]

compounds that, in addition to enhancing the sensitivity to acetylcholine and choline, and to their agonists, of neuronal cholinergic receptors, and/or acting as cholinesterase inhibitors and/or neuroprotective agents, have enhanced blood-brain barrier permeability in comparison to their parent compounds. The compounds are derived (either formally by their chemical structure or directly by chemical synthesis) from natural compounds belonging to the class of amaryllidaceae alkaloids e.g., Galantamine, Narwedine and Lycoramine, or from metabolites of said compounds. The compounds of the present invention can either interact as such with their target molecules, or they can act as “pro-drugs”, in the sense that after reaching their target regions in the body, they are converted by hydrolysis or enzymatic attack to the original parent compound and react as such with their target molecules, or both. The compounds of this disclosure may be used as medicaments for the treatment of human brain diseases associated with a cholinergic deficit, including the neurodegenerative diseases Alzheimer’s and Parkinson’s disease and the neurological/psychiatric diseases vascular dementia, schizophrenia and epilepsy. Galantamine derivatives disclosed herein have higher efficacy and lower levels of adverse side effects in comparison to galantamine, in treatment of human brain diseases.

Benzgalantamine is a prodrug of galantamine. Gastrointestinal adverse effects are the most frequently reported side effects in patients undergoing treatment with cholinesterase inhibitors, including galantamine, and are often a reason for treatment discontinuation.² As a prodrug, benzagalantamine remains inert as it passes through the stomach, thereby avoiding many of the gastrointestinal effects associated with peripheral cholinesterase inhibition.⁴

Benzgalantamine was approved by the FDA in July 2024 for the treatment of mild-to-moderate dementia in Alzheimer’s patients.^3,4
