摘要:
The invention concerns a novel copolymer of N-morpholinoethyl methacrylate and 2-hydroxyethyl methacrylate which can be used in transdermal delivery systems or in oral controlled release products. The invention also concerns a process for preparing the copolymer and a method of using it to administer pharmaceutically active substances.

摘要:
Sustained release solid dosage forms--i.e., tablets, pellets, granules, and powders--can be made using a combination of polymeric and ionic particulate materials to modify release profiles, permeability and processability.
摘要:
A novel solid pharmaceutical dispersion that improves the bioavailability of poorly water soluble drugs is produced by combining the drug with a polymer carrier such as polyvinylpyrrolidone. The drug is combined with the carrier without the need for using organic solvents or melting temperatures (fusion) through the use of a transition compound such as polyethylene glycol which partially solubilizes the drug and/or plasticizes the polymer.
摘要:
Improved thrombin formulations, stable at room temperature using stabilizing quantities of a polyol and a buffer at specific pHs are described wherein crude thrombin is first purified by two-stage ion exchange chromatography.
