Excipient for Inhalation

Abstract Fine powders are required in many industrial applications, but their poor flow properties make handling and processing challenging. In Dry Powder Inhalation (DPI), for instance, inhaled particles must have an aerodynamic diameter between 1 and 5 μm to ensure therapeutic efficiency.…

Multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) continue as public health concerns. Inhaled drug therapy for TB has substantial benefits in combating the causal agent of TB (Mycobacterium tuberculosis). Pretomanid is a promising candidate in an optional…
