Modeling of Drug Release from Erodible Tablets
Abstract
A general mathematical model was developed to describe drug release from erodible tablets undergoing surface erosion. The model (which is based on the Hopfenberg equation) takes into account the three dimensions of a tablet dosage form. The model enables the characterization of the release kinetics by one or two erosion rate constants depending on the hydrodynamic conditions of the system. The model can be used to compare the release rates of the drug within different batches produced under different conditions. The model was utilized to evaluate some factors affecting the release rate from erodible tablets consisting of hydroxypropyl methylcellulose and amoxicillin. The release data of amoxicillin measured from the whole tablet followed the equation developed. Amoxicillin release data measured from the planar surface of the tablet appeared to follow zero-order kinetics as predicted by theory for drug release from an erodible device maintaining constant surface area with time.

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.
