PHARMACEUTICAL COMPOSITION, METHOD OF ITS PREPARATION, AND INFUSION SOLUTION BASED ON THIS COMPOSITION

摘要

A pharmaceutical composition consisting essentially of a compound of the general formula (I) in which R represents a hydrogen atom or an acetyl radical and R1 represents a tert-butoxycarbonylamino or benzoylamino radical, dissolved in a surfactant selected from the group consisting of polysorbate, polyoxyethylene glycol and hydrogenated castor oil, whilst the content of the general formula (I) compound is no more than 200 mg/l and the content of ethanol is less than 5 wt.% relative to the weight of the solvent. A method for preparing a composition which comprises dissolving a compound of the formula (I) in ethanol, adding the surfactant and removing the ethanol by means of evaporation. The said pharmaceutical composition is used to prepare infusion solutions.
