EC N200

Specification of EC N200

Application of EC N200

KimaCell^® EC N200 ethyl cellulose can be used in matrix sustained release, tablet sustained and controlled release coating formulations

• Matrix sustained release tablet

  Insoluble Matrix Sustained-release Tablets Tablets made of water-insoluble or minimally water-soluble polymers or non-toxic plastics. Its drug release is mainly divided into three steps: digestive juice penetrates into the skeleton pores, drug dissolution and drug release from the skeleton pores. EC is one of the commonly used insoluble framework materials. Since the release of fat-soluble drugs from the matrix is too slow, only water-soluble drugs are suitable for the preparation of this matrix tablet. Tablets after granulation.

• Sustained and controlled release coating formulations

  EC is a slow and controlled release coating material widely used at present. In the early stage, the organic solution coating method of EC was mainly used. At present, the water dispersion coating technology is relatively mature.

• Control release solid dispersion

  In recent years, people have used water-insoluble polymers, enteric materials, lipid materials, etc. as carriers to prepare sustained-release solid dispersions, so that the research on solid dispersions has entered a new stage of development. EC solid dispersion is usually prepared by solvent evaporation method, which dissolves or disperses the drug and EC in an organic solvent such as ethanol, evaporates the solvent, and then dries the residue.
