摘要:
A polymer of formula (I): where X 1 and X 2 respectively represent the alpha and omega end groups of the polymer; R 1 represents a hydrogen atom or a straight or branched chain alkyl group; R 2 represents a straight or branched chain alkyl group which is substituted by a group which may have a positive charge at physiological pH; and n represents the number of repetitive units of the polymer; or a copolymer thereof; for use as a medicament and for treatment of a heparin overdose wherein the polymer of formula (I) has been found to have a selectivity and affinity for heparin.
摘要:
Described are gastric residence structures that include an active substance. The gastric residence structures may include one or more arms that include a loadable polymeric component, an elastic polymeric component, and a separate linker component. The linker may connect the one or more arms with the elastic polymeric component. The gastric residence structures may be configured to be folded and physically constrained during administration and may be configured to assume an open retention shape upon removal of a constraint. The change between the folded shape and the open retention shape may be mediated by the elastic polymeric component that undergoes elastic deformation when the residence structure is in the folded shape and recoils when the gastric residence structure assumes the open retention shape.
