Methods Eszopiclone Time-controlled Release Tablets were prepared by using high efficient coating machine. HPMC was used as swelling material, and EC aqueous dispersion as controlled-release coating material. The main factors which influence the drug release characteristics were evaluated, and the dissolution data in vitro were investigated. Results The main factors affecting drug release were identified. The dissolution data in vitro showed that Eszopiclone Time-controlled Release Tablets could achieve the expected pulse release. Conclusion Eszopiclone Time-controlled Release Tablets can achieve twice pulse release, meets the original requirement of helping patients with insomnia to fall asleep quickly and a sleep duration of more than
