Features & Benefits
- Product Highlights
- Chemically stable
The chemical structure of CMEC is built up by ethel linkage, difficult to be hydrolyzed with CMEC itself being chemically stable.
- Disintegration of pH dependency
The disintegration behavior of tablets coated with CMEC depends on the pH regardless of the buffer solution. It is slower to disintegrate in a lower pH but faster in a higher pH. By taking advantage of this property, using enteric material is possible. Also, the combination with controlled release materials of pH independency enables the formulation of various dissolution profiles.
- As a Matrix-Forming Material
CMEC is used for a matrix-forming material with API. The release speed rate is controllable by adjusting the ratio of API and CMEC.
- Improve dissolution of poorly soluble drugs
CMEC is a carrier of solid dispersion for improving solubility of poorly soluble API.
- Protective coating for sugar-coated tablet
The CMEC film thickness of 100μm has suitable moisture prevention. It is effective to use CMEC as protective coating agent on sugar-coated tablets including water-sensitive API.
