Abstract

The invention provides a use of tizanidine hydrochloride and tandospirone citrate in the preparation of a combined drug for treating insomnia. The weight ratio of a tizanidine hydrochloride derivative to the tandospirone citrate is 1-4 to 5-20. The combined drug has the advantages that: (1) from different mechanisms of action, the combined drug has the function of synergistic effect against insomnia; (2) the clinical dosage of one or two drugs can be reduced to attenuate virulence; and (3) the invention can facilitate patients to carry and take.
