The difference between solubility of clopidogrel sulfate form Ⅰ and form Ⅱ in 2-butanol was determined by dynamic method. Based on process analysis and optimization of clopidogrel sulfate crystallization in solutions
clopidogrel sulfate of form Ⅰ was acquired with spherical shape. Compared with the non-spherical products
the spherical one possesses advantages in bulk density
flow ability
size distribution and stability. The crystal habit and crystal form of products prepared at different temperatures and residual solvents were investigated
the kinetics and growth mechanism of the spherical crystallization process was studied.
