title: Effect of inclusion complexation of meloxicam with β-cyclodextrin- and β-cyclodextrin-based nanosponges on solubility, in vitro release and stability studies.
abstract: The objective of the present work was to develop inclusion complexes of meloxicam with β-cyclodextrin- and β-cyclodextrin-based nanosponges to enhance their solubility and stability and to prolong release using different methods that included physical mixing, kneading and sonication. Particle size, zeta potential, encapsulation efficiency, stability study results, in vitro and in vivo drug release study results, FTIR, DSC and XRPD were used as characterization parameters. SEM (Scanning Electron Microscope) studies revealed that the particle sizes of the inclusion complexes of meloxicam were within the range of 350 ± 5.69-765 ± 13.29 nm. The zeta potentials were sufficiently high to obtain stable formulations. In vitro and in vivo release studies revealed the controlled release of meloxicam from the nanosponges for 24h. The interaction of the meloxicam with the nanosponges was confirmed by FTIR and DSC. A XRPD study revealed that the crystalline nature of meloxicam was changed to an amorphous form due to the complexation with the nanosponges. A stability study revealed that the meloxicam nanosponges were stable. Therefore, β-cyclodextrin-based nanosponges represent a novel approach for the controlled release of meloxicam for anti-inflammatory and analgesic effects.
