Methods A double-blind, randomized and controlled test was conducted on zolpidem tartrate and stilnox in the treatment for insomnia. For each individual, the treatment lasted for 1 week and a clinical observation scale was used to assess the effect and side effects on days 1,4 and 8 of the treatment.
