Diving Deep into Carrier-Based Formulation and Process Optimization
December 23rd 2024Carrier-based formulations for dry powder inhalers are carefully designed to transport extremely small particles into the lungs. Jet milling can be used to micronize these particles, with both high and low shear mixing processes used to formulate mixtures capable of carrying the fine API particles into the deep lung. This paper looks at the requirements for pulmonary delivery via carrier-based inhaled powder formulations, and how jet milling can be used to manufacture effective and stable materials for these formulations
