Pulmonary Delivery of Inhalable Nanoparticles: Dry Powder Inhalers

Therapeutic Delivery, 2011
Pulmonary administration of inhalable nanoparticles (NPs) is an emerging area of interest. Dry powder inhalers may offer particular advantages for pulmonary administration of NPs. This article reviews research performed on the formulation of inhalable NPs as dry powder to achieve deep-lung deposition and enhance NP redispersibility.

Formulation Considerations for Dry Powder Inhalers

Therapeutic Delivery, 2014
The market for inhalable dry powder medication has consistently grown over past years. Targeting the lungs has been recognized to offer several advantages compared with oral application of drugs. The successive development of inhalation products has led to advances in local treatment of different respiratory diseases, but has also demonstrated the ...

Developing Dry Powder Inhaler Formulations

Journal of Aerosol Medicine and Pulmonary Drug Delivery
This section aims to provide a concise and contemporary technical perspective and reference resource covering dry powder inhaler (DPI) formulations. While DPI products are currently the leading inhaled products in terms of sales value, a number of confounding perspectives are presented to illustrate why they are considered surprisingly, and often ...

Dry Powder Inhalers: From Bench to Bedside

Journal of Aerosol Medicine and Pulmonary Drug Delivery, 2023
Dry powder inhalers (DPIs) are now widely prescribed and preferred by the majority of patients. These devices have many advantages over the traditional pressurized metered-dose inhaler (pMDI) but they do have disadvantages. The characteristics of the dose emitted from a DPI are affected by the inhalation manoeuvre used by a patient.

Inhaler Systems: Dry Powder

2016
Pulmonary tract is one of the oldest routes used for administration of drugs. During the past decade, the lung has been very attractive for achieving systemic and local absorption of various drugs, particularly for those drugs that exhibit poor bioavailability when administered by the oral or parenteral route.

Exhalation immediately before inhalation optimizes dry powder inhaler use

Journal of Asthma, 2015
Although exhalation immediately prior to inhalation (EPI) from dry powder inhalers (DPIs) is universally advised, its benefit has not been investigated. The objective of this study to assess the effects of EPI on inhaled flow from a DPI.We measured peak inhaled flow rate (PIFR) and inhaled gas volume of 25 volunteers unfamiliar with DPIs.

Dry-Powder Inhalers in Acute Asthma

Therapeutic Delivery, 2013
An updated literature search was performed to evaluate the efficacy of rapid-acting β2-agonists delivered via dry powder inhalers in the treatment of moderate-to-severe acute asthma. Databases were searched from 1985 up to December 2012. A total of 23 randomized, double-blind or open clinical studies in acute asthma comparing the efficacy of a dry ...

Dry powder inhaler and method for pulmonary inhalation dry powder.

2004
A breath actuated dry powder inhaler (1), comprising a substantially disc shaped air circulation chamber (2) for de-agglomeration of entrained powdered medicament using the energy of the inspiratory air stream. The chamber has a substantially circular or polygonal sidewall (3) extending about a central axis (4) between top (5) and bottom walls (6) of ...

Dry Powder Inhalers: Advantages and Limitations

Journal of Aerosol Medicine, 1991
New inhalers have been developed because of difficulty of using the conventional metered dose inhaler (MDI) and because of the impending ban on CFC's. Dry powder inhalers (DPI's) in general are easier to use than the MDI and cause fewer irritant effects.
