Background/Objectives: Dry powder inhalation is an attractive research area for development. Therefore, this work aimed to develop inhalable co-spray-dried theophylline (TN) microparticles, utilizing raffinose-amino acid fine carriers intended asthma therapy. The study addressed enhancing TN’s physicochemical and aerodynamic properties ensure efficient lung deposition. Methods: process involves spray-drying each formulation’s solution using a mini spray drier. A rigorous assessment was conducted on particle size distribution, structural thermal analysis, morphology study, in vitro silico investigation, counter addition the solubility, dissolution, diffusion of TN. Results: containing leucine glycine revealed superior characteristics (mass median diameter (MMAD): 4.6–5 µm, fraction (FPF): 30.6–35.1%, amorphous spherical structure) as candidates further development TN-DPIs, while arginine excluded due intensive aggregation hygroscopicity, which led poor performance. TN samples demonstrated micronized particles (D [0.5]: 3.99–5.96 µm) with predominantly structure (crystallinity index: 24.1–45.2%) significant solubility enhancement (~19-fold). Formulations leucine-glycine highest FPF (45.7–47.8%) deposition (39.3–40.1%), rapid drug release (~100% within 10 min), improved (2.29–2.43-fold), respectively. Moreover, confirmed microparticles (mean number = 2.3–2.02 µm). Conclusions: This innovative formulation possesses enhanced physicochemical, morphological, low-dose local treatment could be applied promising carrier dry inhaler

Cystic fibrosis is a hereditary disease, which causes the accumulation of dense mucus in lungs accompanied by frequent local inflammation. The non-steroidal anti-inflammatory drug ibuprofen (IBU) and mucolytic mannitol (MAN) can treat these symptoms. Compared to per os administration, lower dose drugs sufficient achieve desired effect delivering them pulmonary manner. However, it still challenge administer high doses lungs. We aim develop two inhaled powder formulations, single-drug product MAN combined formulation containing IBU MAN.
