Curcumin-loaded self-emulsifying drug delivery system (cu-SEDDS): a promising approach for the control of primary pathogen and secondary bacterial infections in cutaneous leishmaniasis.

Curcumin-loaded self-emulsifying drug delivery system (cu-SEDDS): a promising approach for the control of primary pathogen and secondary bacterial infections in cutaneous leishmaniasis. Appl Microbiol Biotechnol. 2019 Jul 12;: Authors: Khan M, Ali M, Shah W, Shah A, Yasinzai MM Abstract Cutaneous leishmaniasis being a neglected tropical disease (NTD) faces several challenges in chemotherapy. If infected with secondary bacterial infections, the treatment regime of cutaneous ulcers in cutaneous leishmaniasis is further complicated which usually require two or more than two chemotherapeutic agents for healing. In the current study, seven curcumin-loaded self-emulsifying drug delivery system (cu-SEDDS) formulations (namely F1-F7) were prepared by mixing different excipients (oils, surfactants, and co-solvents) through stirring (vortex) and sonication. The formulations were characterized regarding their droplet size, polydispersity index (PDI), and zeta potential by zeta sizer. The cu-SEDDS formulations displayed different sizes ranging from 32.4 up to 80.0 nm. The zeta potential of the formulations ranged from - 1.56 up to - 4.8. The antileishmanial activities of the cu-SEDDS formulations in terms of IC50 against Leishmania tropica ranged from 0.19 up to 0.37 μg/ml. The minimum inhibitory concentrations (MICs) of these formulations against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Klebsiella pneumoniae were in...
