Embodiment 1
[0102] After mixing varenicline fumarate, microcrystalline cellulose, anhydrous calcium hydrogen phosphate, colloidal silicon dioxide and magnesium stearate and other auxiliary materials, they were compressed with a rotary tablet machine to obtain tablets with a weight of 200 mg. tablet.
[0103] The obtained tablet is coated with a barrier layer, and the coating prescription is shown in the table below.
[0104] Dissolve ethyl cellulose in ethanol solution, add hydrogenated vegetable oil and keep warm in a 70°C water bath to melt the hydrogenated vegetable oil. Finally, under mechanical stirring, cool to room temperature to obtain a coating solution. The actual coating weight gain is 7.0%- 11.0%.
[0105]
Embodiment 2
[0107] The tablet core obtained by tablet compression in Example 1 is coated with an isolation layer. The preparation method of the coating solution is the same as in Example 1, and the actual coating weight gain is 3.0%-5.0%.
[0108]
[0109]
