Co-Micronization
API and excipient, reduced together — for homogeneity that no physical blend can match.
Co-Micronization
Co-micronization is an advanced particle engineering service characterized by the simultaneous size reduction of an API and one or more functional excipients. Unlike standard physical blending, this process utilizes fluid-jet milling technology to achieve an intimate, high-energy interaction between the drug and carrier components at the microscopic level. This interaction is critical for achieving superior homogeneity distribution compared to traditional physical mixtures even in presence of high percentage differences between the mixture component.
The primary technical objective of co-micronization is the optimization of Critical Quality Attributes (CQAs) defined within the Target Product Profile (TPP), such as dissolution kinetics and aerosolization efficiency. By processing the API alongside a carrier, we can effectively manage the high surface energy and electrostatic charges that often lead to poor flowability and particle aggregation in micronized materials. Furthermore, the presence of specific excipients during the comminution phase can help stabilize the amorphous content or surface defects generated by the milling energy, preventing unwanted recrystallization or particle size growth during storage.
Co-Micronization Equipment Schema
Two separate screw feeders are employed to ensure the simultaneous feeding of two different components into the milling chamber of the spiral jet mill through a Venturi system.
Co-Micronization Explained
Co-micronization is a process where a medicine and a "helper" ingredient (called an excipient) are shrunk into microscopic pieces at the same time. Instead of simply mixing two finished powders together, they are crushed together using high-speed air. This ensures they are perfectly blended at a tiny level, creating a specialized combination. This technique is very helpful for medicines that have trouble dissolving; by grinding them together, the medicine can work more effectively in the body while remaining stable and high-quality over time.
