We investigated the feasibility of preparing high-potency tacrolimus dry powder for inhalation using thin film freezing (TFF). We found that using ultra-rapid freezing can increase drug loading up to 95% while maintaining good aerosol performance. Drug loading affected the specific surface area and…

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…
