The invention discloses a preparation method of a solid pharmaceutical composition containing ropinirole or derivatives of ropinirole. The preparation method is characterized by comprising the following steps: firstly, dissolving the ropinirole or derivatives of ropinirole into a proper solvent, then adding the solution to a pharmaceutically acceptable carrier; evenly mixing, drying and then mixing with other materials, and finally preparing into an oral solid preparation. By adopting the method, ropinirole can be rapidly dissolved out, the problems of complicated preparation process and poor content uniformity in the preparation process of the ropinirole preparation can be effectively solved; meanwhile, the stability of ropinirole is not affected.
