  The objective of this work was to prepare and investigate in vitro ciprofloxacin (CPX)-loaded solid lipid microparticles (SLM) against some selected micro-organisms for improved activity. Lipid matrix consisting of Softisan®-154 and Phospholipon® 90H was used to prepare SLMs loaded with CPX. The thermal properties of polymers and the SLMs were determined by a differential scanning calorimetry (DSC), particles size and the pH change of CPX-loaded SLMs were evaluated. The encapsulation efficiency (EE), loading capacity (LC) and in vitro release of CPX from the SLMs were evaluated. The antimicrobial activities of the SLM against selected organisms were determined. Characterizations showed that lipid matrix generated imperfect microstructure that accommodated CPX in a concentration-dependent manner. The EE and LC% were 89.2 and 33%, respectively. Maximum CPX release of > 80% was obtained in batch A3. The antimicrobial activity of the formulation against the tested organisms was comparably higher in batch C (49.10 ± 2.10) against S. aureus and (33.10 ± 0.21 mm) against S. typhii as compared to the reference sample. This result suggests the capability of the SLMs to modify the release of the drug and improve its activities against the microorganisms.
