Drug-carrier particle interactions greatly affect the detachment of drug from the carrier in inhalation powders.

Linking compaction dynamics to the flow properties of powdersG. SEM pictures have been made in order to have an information of the particle size floslac and particles shape:.

FlowLac from MEGGLE USA – Product Description and Details

The measurement and the result analysis are assisted by software. Vandewalle, F,owlac Review Letters How tribo-electric charges modify powder flowabilityA. However, in this application note, we will be focused on the GranuFlow instrument. The flowrate is measured for a set of aperture sizes to obtain a flow curve.

Clowlac this study, a novel multiple dose, reservoir-based Taifun was used as a dry powder inhaler, and the effects of carrier physical properties were evaluated on the pulmonary deposition of budesonide, along with physical stability of the inhalation powder.

The physical properties of the carriers strongly affected the pulmonary deposition of budesonide and the physical stability of the inhalation powder. The GranuFlow allows to classify powders in terms of flowability, even if the classical tap density test is unable to see the Hausner ratio difference.

To prove these assumptions the following figure shows the mass flowrate according to hole diameter: Effect of relative air humidity on the flowability of lactose powdersG.

Influence of cohesives forces on the macroscopic properties of granular assembliesG. In this study, untreated commercial preparation of alpha-lactose monohydrate, highly amorphous spray dried lactose, crystallized spray dried lactose, Flowlac and Flowlac mixed with crystalline micronized lactose were used as f,owlac. The dynamic angle of repose and a bed behavior diagramS.

This fact is highly important, because with the Beverloo model, user can make data interpolation, and thus predicts the mass flowrate for different hole sizes. Cascade of granular flows for characterizing segregationG.

Dry powder formulations were prepared by the suspension method, where the budesonide-carrier ratio was 1: Flowlac comes in third position, while Tablettose80 has the lower flowability. Motion of carbon nanotubes in a rotating drum: Boschini, Powder Technology, The Mass Flowrate flowpac investigated for different hole size from 4mm to 16mm.

All these samples are made of lactose.

Although Flowlac 90 and Tablettose70 have the same Cb parameter, Dmin information allows us to affirm that Flowlac90 has the best flowability from all samples and its followed by Tablettose In particular, the measurement processes have been automatized and rigorous initialization methods have been developed to obtain reproducible and interpretable results.

In this paper, we used a complete set of hole diameters: They are called by the manufacturer Tablettose 70, Tablettose 80, Flowlac 90 and Flowlac This flowrate is computed automatically from the slope of the mass temporal evolution measured with the balance. This graph shows the good correlation between experimental data and modeled values with Beverloo law. When compared to an untreated alpha-lactose monohydrate, the highly amorphous spray dried lactose and Flowlac did not improve aerosol performance of the inhalation powder.

To control and to optimize processing methods, these materials have to be precisely characterized. Stabilisation of Al2O3—SiO2 suspensions for spray drying of composite granules suitable for reactive plasma sprayingA. Dmin is the minimum aperture size to obtain a flow: The main purpose of this application note is to provide information regarding lactose analysis for the Pharmaceutical field.

Vandewalle, Physical Review E 81, Vandewalle, Physical Review Letters 95, European journal of pharmaceutical sciences: Mullite coatings on ceramic substrates: Vandewalle, Powder Technology Measuring the flowing properties of powders and grainsG.

To prove these assumptions the following figure shows the mass flowrate according to hole diameter:. Vandewalle, Physical Review E 82, R Finally, the whole flow curve is fitted with the well-known Beverloo theoretical model to obtain a flowability index Cb, related to the powder flowability and the minimum aperture size to obtain a flow Dmin for theoretical background, user can refer to Appendix 1. Moreover, the use of image analysis techniques improves the measurements precision.

Luyten, Powder Technology— Compaction dynamics of a magnetized powderG. Vertruyen, Journal of the European Ceramic Society 29, — The GranuFlow allows to plot the full mass flowrate curve.

Lactose modifications enhance its drug performance in the novel multiple dose Taifun DPI. Granular materials and fine powders are widely used in industrial applications.

The influence of grain shape, friction and cohesion on granular compaction dynamics flolwac, N. The GranuFlow is a straightforward powder flowability measurement device composed of a silo with different apertures associated with a dedicated electronic balance to measure the flowrate.

Gerasimov, Applied Physics Letters 89, The GranuFlow gives information about the Beverloo law i. The whole measurement is performed easily, fastly and precisely. Vandewalle, Physical Review E 80,
