Preparation, characterisation and in vitro antibacterial property of ciprofloxacin-loaded nanostructured lipid carrier for treatment of Bacillus subtilis infection
2019
AbstractContext: In this study, controlled ciprofloxacin (CIPRO) nanostrustructured lipid carriers of Precirol® ATO 5/Transcutol® HP (batch A) and tallow fat/Transcutol® HP (batch B) was carreid out. Objective: The aim was to improve solubility and bioavailability of CIPRO.Objective: Study of controlled ciprofloxacin (CIPRO) nanostructured lipid carriers of Precirol® ATO 5/Transcutol® HP (batch A) and tallow fat/Transcutol® HP (batch B).Methods: CIPRO concentrations C1–5 (0.0, 0.2, 0.5, 0.8, and 1.0% w/w) as AC1–5 and BC1–5 were prepared by hot homogenisation and characterised by zetasizer, differential scanning calorimetry, Fourier transform infra-red spectroscopy, in vitro drug release and growth inhibitory zone diameter (IZD) on agar-seeded Bacillus subtilis.Results: AC5 achieved polydispersed particles of ∼605 nm, 92% encapsulation efficiency (EE) and –28 mV similar to BC5 (∼789 nm, 91% EE, and –31 mV). Crystallinity indices (AC5 and BC5) were low at 3 and 5%, respectively. CIPRO release in AC5 was ∼9...
