In modern pharmaceutical formulations, phospholipid excipients, owing to their unique structure and functions, are widely employed in advanced drug delivery systems such as liposomes, emulsions, and nanoparticles. They serve not only as “carriers” for drugs but also as the “skeleton” of the formulation; their quality directly impacts the stability, safety, and efficacy of the drug. So, how exactly does the quality of phospholipid excipients affect pharmaceutical preparations? Today, we’ll delve into this question by examining several key quality indicators.
