General description
Stearic acid, a saturated fatty acid, is essential in biologic drug formulations, where it is used to stabilize emulsions and to prepare lipid-based carriers for drug delivery. Its use in the synthesis of solid lipid nanoparticles helps in enhancing the bioavailability of poorly soluble drugs. Stearic acid also plays a role in improving the pharmacokinetic profile of biologics, contributing to their stability and efficacy in therapeutic applications.
The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics.
