    摘要： A homogeneous steroid-containing preformulation for production of solid and semi-solid pharmaceutical preparations containing a uniform constant dosage of at least one steroid in a range from 0.001 to 1 percent by weight is described. This steroid-containing preformulation contains of from 0.001 to 50 percent by weight of the at least one steroid. The homogeneous steroid-containing preformulation is made by a method including dissolving the at least one steroid in a solvent to form a dispersant; dispersing an adjuvant consisting of adjuvant particles in the dispersant in a mass ratio of the adjuvant to the at least one steroid of 1:1 to 1000:1 to form a suspension; and creating a spray-mist of the suspension so as to evaporate and remove the solvent from the suspension and thus to form a dried particulate which includes steroid-containing particles. The droplets in the spray mist have a droplet diameter greater than a mean diameter of the adjuvant particles. The maximum particle size of the dried particulate forming the steroid-containing preformulation is increased by less than 30 percent in comparison to an average particle size of the adjuvant particles.
