Abstract
The present invention relates to a thixotropic pharmaceutical composition in which the viscosity is changed due to external mechanical stress applied so that isothermal and continuous gel/sol/gel transition occurs. The thixotropic pharmaceutical composition includes a pharmacologically active substance, a biocompatible thickener having a predetermined thixotropic property, and optionally a hydrophilic thickener. The viscosity of the composition is relatively rapidly changed within a predetermined range. Accordingly, it is easy to measure the amount of drugs to be administered, it is possible to administer a precise amount of drugs to a patient, the compliance of a patient with dosage of drugs is high, and it is easy to produce the composition.
