Abstract

Galantamine hydrobromide, a promising acetylcholinesterase inhibitor is reported to be associated with cholinergic side effects. Its poor brain penetration results in lower bioavailability to the target site. With an aim to overcome these limitations, solid-lipid nanoparticulate formulation of galantamine hydrobromide was developed employing biodegradable and biocompatible components. The selected galantamine hydrobromide-loaded solid-lipid nanoparticles offered nanocolloidal with size lower than 100 nm and maximum drug entrapment 83.42 ± 0.63%. In vitro drug release from these spherical drug-loaded nanoparticles was observed to be greater than 90% for a period of 24 h in controlled manner. In vivo evaluations demonstrated significant memory restoration capability in cognitive deficit rats in comparison with naive drug. The developed carriers offered approximately twice bioavailability to that of plain drug. Hence, the galantamine hydrobromide-loaded solid-lipid nanoparticles can be a promising vehicle for safe and effective delivery especially in disease like Alzheimer's.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
