I have been redirected to this forum from Chemistry SE.
My problem consists of a structure (say a cylinder) made from a homogenous distribution of a drug from a polymeric matrix. These compounds are mixed homogeneously in different concentrations (10% drug and 90% polymer, or, 20% drug and 80% polymer) and extruded to form the structure. This structure is immersed in a media.
As the structure interacts with the media, the drug and the polymer degrades into the media and the media is able to diffuse into the structure and the drug in the interior breaks down. This continues till the entire structure is degraded (however, I am interested in only till all drug has been released).
I want to find out how the structure will physically and chemically degrade. I also want to find out what the rate of drug dissolution in the media will look like, and how the structure would look in 3D over time.
Is there any computational tool that can model this problem and provide a solution.
Any help will be appreciated!!
