Message: | It applies to the dosage forms (tablets, capsules, granules, pellets, etc.) require keeping intact in stomach and disintegrating or dissolving in intestine. Such series of enteric coatings take cellulose derivatives or synthetic acrylic polymers as film-forming material, which contain carboxyl groups that can be ionized, and in the acidic gastric environment, the carboxyl non-ionizing, the polymer is not dissolved; but in intestinal alkaline environment, carboxyl ionization caused swelling or dissolved polymer to achieve the release of the drug.
EASCOL EOBS68
Product Features:
- Take 80% ethanol as solvent, which yields high coating efficiency, low energy consumption, and low requirement on dryness efficiency of coating equipment;
- Good anti-acid property, to withstand gastric acid effectively for 2 hours with 4%-6% weight gain; the membrane dissolve when pH ≥6.8;
- Low viscosity, be prone to atomization (taking 80% ethanol as solvent and with 8%-10% Solid Content), glossy film membrane;
- The film membrane is friable which is not fit for coating core tablets with higher friability and sharp edge. url:http://www.tjile.com |
