The filling of powders into two-piece hard capsules.
The factors that influence the filling of powders into hard capsules are reviewed. Powder properties that affect machine performance and influence plug formation are highlighted. The use of instrumented machines and machine simulators in formulation development are described. The properties of excipients that are required for uniform filling are identified. The use of optimisation techniques to produce rational formulations is discussed.
