Dry Powder Inhalers (DPI)
Design of Experiment (DoE) Approach for Developing Inhalable PLGA Microparticles Loaded with…
Abstract
Tuberculosis (TB) is an airborne bacterial infection caused by Mycobacterium tuberculosis (M. tb), resulting in approximately 1.3 million deaths in 2022 worldwide. Oral therapy with anti-TB drugs often fails to achieve therapeutic concentrations at the primary infection site (lungs). In…

Fine excipient materials in carrier-based dry powder inhalation formulations: The interplay of…
Abstract
The contributions of fine excipient materials to drug dispersibility from carrier-based dry powder inhalation (DPI) formulations are well acknowledged, although they are not fully elucidated. To improve the understanding of these contributions, we studied the influences of the particle…

Effect of drug load on the aerosolisation propensity of binary adhesive mixtures for inhalation
Abstract
The aim of this study was to investigate how the propensity for aerosolisation in binary adhesive mixtures was affected by the drug load, and to determine whether these findings could be linked to different blend states. Binary blends of two different lactose carriers, each with varying…

Lipid-coated nanocrystals of paclitaxel as dry powder for inhalation: Characterization, in-vitro…
Abstract
Background
Nanocrystals can be produced as a dry powder for inhalation (DPIs) to deliver high doses of drug to the lungs, owing to their high payload and stability to the shear stress of aerosolization force. Furthermore, lipid-coated nanocrystals can be formulated to improve the drug…

Novel inhalable powder formulation of pirfenidone with sustained release properties to improve…
Abstract
The aim of this study was to develop a new respirable powder (RP) formulation of pirfenidone (PFD) with sustained release properties to ameliorate the pharmacokinetic drawbacks of the previously-developed PFD-RP on rapid elimination from the lung after insufflation. Based on screenings…

Improving Inhalation Performance with Particle Agglomeration via Combining Mechanical Dry Coating…
Agglomerate formulations for dry powder inhalation (DPI) formed with fine particles are versatile means for the highly efficient delivery of budesonide. However, uncontrolled agglomeration induces high deposition in the upper airway, causing local side effects due to high mechanical strength, worse…
