The Delivery of High-Dose Dry Powder Antibiotics by a Low-Cost Generic Inhaler.

The routine of loading multiple capsules for delivery of high-dose antibiotics is time consuming, which may reduce patient adherence to inhaled treatment. To overcome this limitation, an investigation was carried out using four modified versions of the Aerolizer® that accommodate a size 0 capsule for delivery of high payload formulations. In some prototypes, four piercing pins of 0.

Effect of device design on the aerosolization of a carrier-based dry powder inhaler--a case study on Aerolizer(®) Foradile (®).

The objective of this study is to investigate the effect of device design of the Aerolizer(®) on the aerosolization of a carrier-based dry powder inhaler formulation (Foradile(®)). The Aerolizer was modified by reducing the air inlet size and mouthpiece length to 1/3 of the original dimensions, or by increasing the grid voidage. Aerosolization of the powder formulation was assessed on a multi-stage liquid impinger at air flow rates of 30, 60, and 100 L/min.
