Molecular 3D Characterisation of Drug Distribution and Mg-Stearate Coating on Lactose Carrier Particles by ToF-SIMS and XPS
A common type of inhalation medicine uses a dry powder formulation where the active pharmaceutical ingredient (API) is attached on the surface of carrier particles, often in combination with additional components. The spatial distribution of the API on the carrier particle is critical for the release into the lungs and thus for the efficacy of the drug. In this work, we use ToF-SIMS imaging in com
