Vicagrel Tablet Formulation and Manufacture

Example 5

The pulverized vicagrel was subjected to stirred mixing with pregelatinized starch, mannitol, low-substituted hydroxypropyl cellulose, and hydroxypropyl methyl cellulose in a high-shear granulator for 5 min, stirred at a linear speed of 4 m/s, and sheared with a shearer at 800 rpm, and granulated with added water, the particles were deagglomerated through a 10-mesh sieve, and dried in a fluidized bed while maintaining the bed temperature below 60° C. during drying. The particles were removed, and sized through a 24-mesh sieve, and sodium stearyl fumarate was added and mixed, and tableting was performed on a 10-punch rotary tablet press (ZP-10A, Sinopharm Longli), with a 8 mm shallow concave punch.
