In vitro study of nanoliposomes containing curcumin and doxycycline for enhanced antimicrobial photodynamic therapy against Aggregatibacter actinomycetemcomitans

The excessive inappropriate use of systemic antibiotics has contributed to the emergence of antibiotic-resistant pathogens, which pose a significant risk to the success of treatment. This study has approached this problem by developing doxycycline-loaded liposome doped with curcumin (NL-Cur +Dox ) f...

description The excessive inappropriate use of systemic antibiotics has contributed to the emergence of antibiotic-resistant pathogens, which pose a significant risk to the success of treatment. This study has approached this problem by developing doxycycline-loaded liposome doped with curcumin (NL-Cur +Dox ) for combination antibacterial therapy against Aggregatibacter actinomycetemcomitans . The characterization of formulation revealed encapsulation of both drugs in NL-Cur +Dox with an average size of 239 nm and sustained release behavior. Transmission electron microscopy analysis confirmed the vesicular-shaped nanocarriers without any aggregation or crystallization. The cytotoxic and hemolytic activities of NL-Cur +Dox were evaluated. The anti-biofilm and anti-metabolic effects of NL-Cur +Dox -mediated antimicrobial photodynamic therapy (aPDT) were examined. The data indicated that NL-Cur +Dox -mediated aPDT led to a significant reduction of biofilm (82.7%, p  = 0.003) and metabolic activity (75%, p
