Solubility enhancement of meloxicam by phospholipid complexation

Abstract

The best solubility enhancement approach is phospholipids complexation. It has been effectively employed by a number of writers to enhance the permeability, oral bioavailability, and solubility of several medicinal substances. The meloxicam is a member of BCS Class II, and because of its poor solubility and high permeability, its clinical application may have been constrained. Therefore, it is necessary to use a method that modifies the biopharmaceutical features. In this work, meloxicam, an NSAID with demonstrated anticancer action, was combined with phospholipid to increase its solubility. Utilizing solvent evaporation, the meloxicam phospholipid complex was produced. Particle size, zeta potential, SEM analysis, in vitro drug release, and solubility were assessed for the produced complex. The results obtained in this study showed the smaller particle size in nanometer range and physical stability with desired zeta potential. Meloxicam's prolonged release from the phospholipid complex is demonstrated by the in vitro drug release investigation.  The apparent solubility analysis of meloxicam phospholipid complex. Pure meloxicam showed that the drug's solubility was several times higher than that of the pure form. Hence in conclusion we can say that the phospholipid complexation could be the ideal method for solubility enhancement of drug like meloxicam.
