The invention discloses a treating method for a nanometer suspension solidification process, and belongs to the field of medicine preparations. The nanometer suspension comprises a medicine, a stabilizing agent and water. The method includes adding a surfactant into the medicine nanometer suspension before solidification, and solidifying. Before solidification of the nanometer suspension, 0.01-10% (w / v) of the surfactant is added to inhibit particle aggregation in the solidification process and to maintain the particle size, thus preparing nanometer crystal powder uniform in particle size distribution and easy in redispersion. The method reduces the using amount of a conventional solidification protective agent, and even can fully replace the conventional protective agent, thus increasing the medicine content in the nanometer crystal powder, reducing the cost of auxiliary materials and improving medicine taking compliance.
