摘要:
A storage stable liquid polymer composition is described containing a water-soluble, low viscosity cellulosic polymer, a bleaching agent and a pharmaceutically or veterinarily acceptable vehicle. Uses of this composition include the bleaching of teeth, treatment of dental plaque, gingivitis, and other oral and periodontal diseases that respond to chemical oxidising agents.
摘要:
Système de libération colique destiné à libérer un médicament au niveau du côlon. Le système comprend un médicament combiné à une matrice, la matrice comprend un polymère contenant un saccharide. Selon l'invention, la matrice est résistante à la dégradation chimique et enzymatique dans l'estomac et dans l'intestin grêle. La matrice est dégradée dans le côlon par l'action enzymatique bactérienne, et le médicament se libère. Le système est utile pour cibler des médicaments sur le côlon afin de traiter des maladies coliques. Le système est également utile dans l'administration entérique de médicaments tels que des protéines et des peptides, lesquels sont autrement dégradés dans l'estomac et dans l'intestin grêle.
摘要:
The invention relates to liquid methacrylic acid (co)polymer compositions that contain a release adjusting agent and a pharmacological agent. The compositions form a solid film upon drying, and are capable of accomplishing the sustained release of the pharmacological agent such as to permit its use in the treatment or prevention of dental or dermatological conditions.
摘要:
A colonic delivery system for delivering a drug to the colon is provided. The system comprises a drug in combination with a matrix, wherein the matrix comprises a saccharide-containing polymer. According to the invention, the matrix is resistant to chemical and enzymatic degradation in the stomach and small intestine. The matrix is degraded in the colon by bacterial enzymatic action, and the drug is released. The system is useful for targeting drugs to the colon in order to treat colonic disease. The system is also useful for enteric administration of drugs such as proteins and peptides which are otherwise degraded in the stomach and small intestine.
