Meloxicam-amino acids salts/ion pair complexes with advanced solubility, dissolution, and gastric safety

Amino acids have attracted attention as a potential functional excipient for optimizing biopharmaceutics characteristics of poorly soluble drugs. The amino acids are a diverse class with many functional groups, natural compounds, biocompatible, and low-molecular-weight substances. Two amino acids serine and arginine were investigated with meloxicam. Meloxicam has extremely low solubility; being NSAIDs, gastric upset, and ulcer are common side effects. Solid dispersions were produced by precipitation and physical mixing techniques. The produced combinations underwent
