Micromixing
In pharmaceutics, micromixing is a process in which ingredient particles rearrange to form a blend. Development of pharmaceutical formulations requires understanding how the ingredients blend with each other and how the blending progresses through different stages. It is also important to establish in a scientific manner when the blending is considered complete, establishing the margins of blending performance, so that in production the blending is complete before the blending process stops. Optimal blending In order to achieve optimal blending, the micromixing process must be studied to determine mixing parameters such as blending time, blending speed, type and size of blender. When blending is performed too long, overblending may occur, with particles re-aggregating, resulting in segregation of the previously ideal blend. Tools Formulation scientists and technologists need tools to select ingredients for new formulations. Tablets contain multiple ingredients beyond the activ ...

Pharmaceutics
Pharmaceutics is the discipline of pharmacy that deals with the process of turning a new chemical entity (NCE) or old drugs into a medication to be used safely and effectively by patients. It is also called the science of dosage form design. There are many chemicals with pharmacological properties, but need special measures to help them achieve therapeutically relevant amounts at their sites of action. Pharmaceutics helps relate the formulation of drugs to their delivery and disposition in the body. Pharmaceutics deals with the formulation of a pure drug substance into a dosage form. Branches of pharmaceutics include: *Pharmaceutical formulation *Pharmaceutical manufacturing *Dispensing pharmacy *Pharmaceutical technology *Physical pharmacy *Pharmaceutical jurisprudence Pure drug substances are usually white crystalline or amorphous powders. Before the advent of medicine as a science, it was common for pharmacists to dispense drugs ''as is''. Most drugs today are administered as p ...
