Dry Powder Inhalers (DPI)
Emerging trends in inhaled drug delivery
Ideally, inhaled therapy is driven by the needs of specific disease management. Lung biology interfaces with inhaler performance to allow optimal delivery of therapeutic agent for disease treatment. Inhalation aerosol products consist of the therapeutic agent, formulation, and device. The…

Spray Drying for the Preparation of Nanoparticle-Based Drug Formulations as Dry Powders for…
Nanoparticle-based therapeutics have been used in pulmonary formulations to enhance delivery of poorly water-soluble drugs, protect drugs against degradation and achieve modified release and drug targeting. This review focuses on the use of spray drying as a solidification technique to produce…

Performance tuning of particle engineered mannitol in dry powder inhalation formulations
Typically, smooth lactose particles are used as carrier in dry powder formulations for inhalation. Two classical approaches to improve their aerodynamic behaviour are the addition of fines (milled lactose) or magnesium stearate (MgSt). Mannitol (Parteck® M DPI) as an alternative carrier was used in…

Development of an Innovative, Carrier-Based Dry Powder Inhalation Formulation Containing Spray-Dried…
Most of the marketed dry powder inhalation (DPI) products are traditional, carrier-based formulations with low drug concentrations deposited in the lung. However, due to their advantageous properties, their development has become justified. In our present work, we developed an innovative,…

A shear cell study on oral and inhalation grade lactose powders
Shear cell tests have been conducted on twenty different lactose powders, most of which commercially available for oral or inhalation purposes, spanning a wide range of particle sizes, particle morphologies, production processes. The aims of the investigation were: i) to verify the reliability of…

Respiratory Drug or Vaccine Delivery Using Nanoparticles
Respiratory diseases account for a very significant portion of worldwide morbidity and mortality but to-date only a limited number of therapeutics are available for direct delivery via inhalation. Nanotechnology offers a range of potential benefits to facilitate the targeted delivery/co-delivery of…

Influence of Composition and Spray-Drying Process Parameters on Carrier-Free DPI Properties and…
Although dry powder inhalers (DPIs) have attracted great interest compared to nebulizers and metered-dose inhalers (MDIs), drug deposition in the deep lung is still insufficient to enhance therapeutic activity. Indeed, it is estimated that only 10–15% of the drug reaches the deep lung while 20% of…
