An apparatus and method for monitoring the dissolution properties of a solid
dosage
form pharmaceutical or other material. The apparatus includes a hollow dissolution
chamber for supporting the dosage form and subjecting it to a dissolution liquid
so that the dosage form dissolves in the liquid. A dissolution liquid analyzing
device (e.g., a spectrophotometer) analyzes the properties of the dissolution liquid
as the dosage form dissolves. A video monitoring means (e.g., a stereo-microscope
and video camera) provides a series of images of the dosage form as it dissolves.
The series of images and data resulting from the analysis are recorded and correlated.
The temperature, flow rate and chemical parameters of the dissolution liquid can
be controlled (e.g., held constant or altered), if desired.
