The burden of chronic lung diseases has increased dramatically over the past decades. In terms of prevalence, the five most prominent lung diseases are asthma, tuberculosis, chronic obstructive pulmonary disease (COPD), lung cancer and pneumonia caused by various infections. Local treatment of the conditions compared to oral or parenteral drug delivery could be more efficient with better patient compliance.Among the pulmonary drug delivery systems, the application of dry powder inhalers (DPIs) continues to grow in therapy due to their outstanding stability, ease of use and low production costs. Advantages compared to propellant aerosols are that the inhaled air stream delivers the drug to the airways, which can significantly reduce greenhouse gas emissions. Compared to conventional carrier-based DPIs, carrier-free DPIs are more effective, because the active pharmaceutical ingredient (API) creates a complex system with additives. Due to their special morphology, structure, and better aerodynamic properties, even low respiratory function is enough for proper lung deposition.The majority of APIs used today are poorly water-soluble. Nanosized drugs can provide higher bioavailability due to their smaller particle size and larger specific surface. The various size reduction methods include bottom-up and top-down approaches. Watersolubility can be improved by applying particle engineering techniques that also enable new, alternative administration routes.Although pulmonary therapy would benefit from the use of nanoparticles, there is no commercially available formulation yet. The main challenge is that the required aerodynamic particle size should be between 1-5 µm. For this, the "nano-in-micro" structure could be a solution, having the advantages of nanosized drugs while providing adequate aerodynamic properties. The combination of wet milling, as a top-down particle size reduction method, and spray drying, as a bottom-up technology, could be suitable for their preparation. These systems deposit deeper into the respiratory tract compared to the conventional formulations, while overcoming its elimination mechanisms.It is difficult in pharmaceutical technology to find organic solvent-free, scalable, cost-effective and time-saving techniques that are suitable for the preparation of the "nanoin-micro" DPIs. This thesis reports the development of DPIs containing the non-steroidal anti-inflammatory agent (NSAID) meloxicam (MX) using a combined preparation technique with the aim of effective pulmonary delivery.
