摘要:
This invention pertains to a sustained release complex, Compound (I), which comprises Compound (A), having formula (A) or a pharmaceutically acceptable salt thereof, and a copolymer comprising poly-(I)-lactic-glycolic-tartaric acid (P(I)LGT), wherein the amino group of said Compound (A) is ionically bound to a carboxyl group of the P(I)LGT. The present invention further pertains to a process for making said sustained release complex. Further still, the present invention is directed to a pharmaceutical composition comprising said sustained release complex and a pharmaceutically acceptable carrier(s).
摘要:
Peptide derivatives containing one or more substituents separately linked by an amide, amino or sulfonamide bond to an amino group on either the N-terminal end or side chain of a biologically active peptide moiety. The peptide derivatives have relatively enhanced biological activity when compared to the corresponding peptide alone.
摘要:
This invention relates to the parenteral administration of solid drug compositions. In particular the invention relates to an external, wearable device for the automatic, controlled administration of a solid drug composition to a patient comprising: a housing (32,34); a plunger (36) located within said housing; a dispensing tube (40) attached to said housing, said tube being designed to contain a solid drug composition consisting essentially of said drug and up to 50%, by weight, of a pharmaceutically acceptable carrier; an actuator (54) arranged within said housing to move said plunger from said housing into said dispensing tube; a controller that acts on said actuator to regulate the movement of said plunger through said housing and into said dispensing tube; and a power source (52) arranged to provide energy to said actuator and said controller; wherein said plunger moves the solid drug composition out of said dispensing tube at a controlled rate.
摘要:
A process for preparing polymer microspheres and nanospheres comprising a polymer and a peptide, which comprises the steps of:
dissolving a salt of a peptide complexed with an anionically or cationically functionalized biodegradable polyester in an organic solvent to form a solution; dispersing the solution in an aqueous solution of a surfactant; and evaporating the organic solvent to isolate the polymer microspheres and nanospheres.
