摘要： The present application and its embodiments teach stable compositions of fosaprepitant or a pharmaceutically acceptable salt thereof with such compositions lacking polysorbate 80 and containing dual functional excipients of hydrolysis inhibition and solubility enhancement. Further described are methods of preparation of such compositions. Among other advantages of contemplated compositions, fosaprepitant hydrolysis degradation is kept low and the compositions maintain physically and chemically stable for prolonged period.

摘要： Compositions and methods are provided for reducing adverse reactions as a result of parenteral administration of certain phenothiazine derivatives such as promethazine hydrochloride. The active compound may be admixed with an effective amount of one or more cyclodextrin derivatives, and if desired, one or more non-ionic surfactants such as the partial esters of sorbitol and the polyoxyethylene oxides of long chain fatty acids such as the polysorbates.

摘要： Compositions and methods are provided for reducing adverse reactions as a result of parenteral administration of certain phenothiazine derivatives such as promethazine, including promethazine hydrochloride. The active compound may be admixed with an effective amount of one or more non-ionic surfactants and at least one amino acid and/or one polyol prior to administration to an animal such as a mammal.
