Application


  • Stability test of novel combined formulated dry powder inhalation system containing antibiotic: physical characterization and in vitro-in silico lung deposition results.: This study investigates a novel dry powder inhalation system formulated with an antibiotic and sodium stearate. It explores the physical characterization and lung deposition efficiency, demonstrating the potential for enhanced drug delivery to the lungs (Benke et al., 2019).

  • Protective effect of sodium stearate on the moisture-induced deterioration of hygroscopic spray-dried powders.: This research highlights the role of sodium stearate in protecting hygroscopic spray-dried powders from moisture-induced degradation, which is crucial for maintaining the stability and efficacy of pharmaceutical products (Yu et al., 2018).

  • Dissolution of a poorly water-soluble drug dry coated with magnesium and sodium stearate.: This study examines the use of sodium stearate in enhancing the dissolution rates of poorly water-soluble drugs, which is critical for improving drug bioavailability (Tay et al., 2012).
