margin-right:0px; 0000002151 00000 n With the advent of polymorphism reproductive powers are divided. This is particularly important in flocculated systems in which rapid particle settling is the primary factor leading to physical instability and lack of dosage uniformity in the product. The ability to identify, understand, and control the polymorphic form of a material is important to multiple technical fields but is of special relevance to the field of pharmaceuticals. float: left; The effect of polymorphism on pharmaceutical processing also depends on the formulation and the manufacturing process. properties which can be crucial for their application.
