    (Newlands Press Ltd, 2023-02-07T00:00:00) Handa, Mayank; Kumar, Kamlesh; Garabadu, Debapriya; Kushawaha, Pramod Kumar; Shukla, Rahul
    Aim: In the present work, fixed-dose combination of bilayer tablets for piroxicam as and curcumin as immediate-release and sustained-release layer (SRL) respectively for management of inflammatory response. Materials & methods: The SRL include Curcumin polycaprolactone microparticles from spray drying. The tablet layers include Pearlitol 200SD, Microcrystalline cellulose PH101, Aerosil 200, talc each layer. Results: SEM studies confirm spherical microparticles. PXRD and DSC studies confirm the amorphous microparticles. In vitro studies exhibit, an immediate release and sustained release for Piroxicam and Curcumin after 2 h. Cellular uptake studies on RAW 264.7 cells confirm the complete internalization of microparticles. Conclusion: Therefore, it was concluded that microparticles can be formulated into a unit dosage form for the management of inflammation. � 2023 Newlands Press.

    Purpose: Complicated intra-abdominal infection (cIAI) management involves administering antibiotics that destroy the cell wall and the genesis of bacterial lipopolysaccharide (LPS). During the infectious state, the expression of transferrin receptors upregulates on the intestinal epithelial cells, which are considered the site of infection. In the present research, transferrin decorated poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) encapsulated moxifloxacin (MOX) were developed for possible targeting of the receptors in the colon. Significance: This study will explore more about the incorporation of transferrin as effective coating material in targeted drug delivery. Methods: Nanoparticles were prepared using nano-emulsification and surface modification with transferrin was done by layer-by-layer methodology and evaluated by powder X-ray diffraction (PXRD), differential scanning calorimeter (DSC), FTIR, SEM, antibacterial activity, and cellular uptake studies. Results: The formulated NPs exhibit a size of ?170 nm, PDI�?�0.25, zeta potential�??4.0 mV, drug loading�?�6.8%, and entrapment efficiency of 82%. Transferrin-decorated NPs exhibit tailored release for almost 12 h and in�vitro antibacterial activity for 14 h. The cellular uptake studies were done on a RAW264.7 cell line for better determination of transferrin uptake of fabricated NPs. Conclusion: The above study circumvents around the preparation of transferrin decorated PLGA encumbered MOX NPs intended for cIAI-induced sepsis. PLGA NPs provide tailored release of MOX with primary burst and followed by sustained release. These observations confines with antibacterial activity studies. The prepared transferrin-coated NPs were stable and effectively uptaken by RAW264.7 cells. However, future studies include the preclinical investigation of these NPs in sepsis-induced murine models. � 2023 Informa UK Limited, trading as Taylor & Francis Group.
