Objectives: Liposomes are a promising drug carrier for inhaled delivery systems and their physical parameters could influence therapeutic efficacy significantly. This study was designed to answer the specific question of proper surface charge liposomes in pulmonary inhalation, as well synergistic anti-inflammation between drugs. Methods: In this work, series drug-loaded with different charges (from negative positive) were prepared, several vitro vivo assays, including cytotoxicity, hemolysis assay, mucus penetration lipopolysaccharide (LPS)-induced pneumonia model test, adopted evaluate biocompatibility above liposomes. Results: Compared cationic liposomes, anionic capable better good (low blood compatibility mild tissue inflammation), but poor cellular uptake by immune cells. specific, even when liposome only +2.6 mV, its cytotoxicity reached around 20% 15%, respectively. Furthermore, there no significant difference (−25.9 vs. −2.5 mV), slightly negative-charged exhibited uptake. Conclusions: Thus, (−1~−3 mV) be considering both biocompatibility. an LPS-induced mouse model, achieved anti-inflammatory compared free

Chronic Obstructive Pulmonary Disease (COPD), the third leading cause of death globally, poses a significant public health burden. Despite its high prevalence, underdiagnosis and poor treatment adherence remain major challenges, contributing to increased hospitalization mortality. This study aimed assess inhalation therapy among COPD patients treated at specialty hospital in Quito, Ecuador. A cross-sectional was conducted on 85 diagnosed with tertiary Quito. Data collected through face-to-face surveys, utilizing TAI-10 questionnaire adherence, along demographic clinical characteristics patients. Among participants, 34.1% demonstrated good therapy, while 32.9% exhibited intermediate were non-adherent. The majority older adults aged ≥76 years (67.1%) prevalence comorbidities (91.8%), particularly hypertension (58.8%). Non-adherence primarily associated forgetfulness financial constraints. Higher BMI significantly linked better obese showing higher odds (OR=7.228, 95% CI 1.866-27.996) (OR=9.966, 2.538-39.139). Approximately one-third Ecuador demonstrate similar proportions show or adherence. Predominantly retirees comorbidities, population identified constraints as key barriers. These findings emphasize need for enhanced patient education, regular follow-ups, tailored support vulnerable groups.
