Physical stability of dry powder inhaler formulations

Dry powder inhaler formulation.

A drug product combines pharmacologic activity with pharmaceutical properties. Desirable performance characteristics are physical and chemical stability, ease of processing, accurate and reproducible delivery to the target organ, and availability at the site of action. For the dry powder inhaler (DPI), these goals can be met with a suitable powder formulation, an efficient metering system, and ...

Promising ternary dry powder inhaler formulations of cromolyn sodium: formulation and in vitro-in vivo evaluation.

Glucose monohydrate and sorbitol were evaluated as alternative carriers to á-lactose monohydrate in dry powder inhalations. Cromolyn sodium (CS) - carrier binary formulae were prepared and tested in vitro by aerosolization via a twin stage impinger using three types of inhaler devices; Spinhaler, Aerolizer and Handihaler. Glucose monohydrate and sorbitol-containing formulae that were inhaled vi...

Patient handling of a dry-powder inhaler in clinical practice.

BACKGROUND Multi-dose dry-powder inhalers are perceived as being easier for patients to use than conventional pressurized aerosol inhalers; however, no study has determined whether patients handle such devices adequately and whether there is a need for patient education in this area. METHOD We used trained observers to assess the handling of a specific multi-dose dry powder inhaler (Turbuhale...
