The present invention relates to the p-toluenesulfonic acid co-crystals of agomelatine of formula (I), preparation and use thereof, and to pharmaceutical composition containing it. The p-toluenesulfonic acid co-crystals of agomelatine obtained through the present method has significant increased solubility than agomelatine, and therefore is more suitable for manufacturing pharmaceutical formulations. In addition, the product enjoys good stability and purity. Using the present method, product of high purity can be obtained through a simple process, free of any complicated steps.
