Can a colloid mill be applied in cough powder production to ensure the active ingredients are evenly distributed?

A colloid mill supports cough powder production when powders are first suspended in a liquid carrier for wet blending, since the high shear disperses active ingredients, flavoring agents and excipients evenly throughout the mixture before drying, which helps prevent uneven potency between doses. This wet dispersion step is particularly useful when active compounds are prone to clumping or uneven distribution during simple dry mixing.
