Embodiment 1
[0019] Preparation of pill cores
[0020] 1. Preparation of the main drug coating solution: add 15 g of ethyl cellulose and 1 g of vortioxetine accurately weighed into the 60% ethanol solution, stir evenly, and filter the resulting suspension with a 80-mesh sieve to form a solid content 55% coating liquid, keep stirring when spraying liquid.
[0021] 2. Pour 21g of sucrose blank core into the coating pan and preheat it. When the internal temperature of the sucrose blank core reaches above 45°C, adjust the speed in the coating pan to about 20rpm, turn on the peristaltic pump and spray gun to start coating, The spray flow rate is controlled at 70-80g / min. After coating the main drug, open the air exhaust and air intake valves, the coating pan rotates at 5 rpm, and the drying heating temperature is 50°C, and is dried for 5 hours, and the pellets are passed through 12-mesh and 20-mesh sieves to obtain the product.
