Abstract Previously, granulated lactose carriers were shown to improve uniformity and aerosolization of a low-dose model drug. In the present study, the blending uniformity and aerosol dispersion performance were assessed for 2 model drugs salbutamol sulfate (SS) and rifampicin (RIF), blended at high loadings (10% or 30% drug) with granulated lactose carriers. The model drug powders differed in particle size distribution, morphology, density, and surface energies. Content uniformity of RIF...

Drugs for inhalation are no longer exclusively highly crystalline small molecules. They may also be amorphous small molecules, peptides, antibodies, and myriad types of engineered proteins. The evolution of respiratory therapeutics has created a need for flexible formulation technologies to engineer respirable particles. These technologies have enabled medicinal chemists to focus on molecular design without concern regarding compatibility of physicochemical properties with traditional,...

This study aims to investigate the effect of carrier characteristics and dosator capsule filling operation on the in vitro deposition of mixtures containing salbutamol sulphate (SS) and lactose and mannitol as model carrier materials. The carrier surfaces of lactose and mannitol were modified via wet decantation. More

Purpose Properly charged particles can be used for effective lung targeting of pharmaceutical aerosols. The objective of this study was to characterize the performance of a new induction charger that operates with a mesh nebulizer for the production of highly charged submicrometer aerosols to bypass the mouth-throat and deliver clinically relevant doses of medications to the lungs. http://link.springer.com/article/10.1007/s11095-015-1682-6
