Liposomal Product Characterization

Online Inquiry

BOC Sciences characterizes liposome drugs according to the FDA production and control (CMC) guidelines. We can test for physicochemical properties, encapsulation efficiency, and in vitro drug release and stability, and other specifications.

Why Characterize Liposome Products?

Characterizing liposome products reinforce quality control, which can ensure reproducibility. Assessment of liposome critical quality attributes (CQAs), such as physicochemical properties, composition, encapsulation efficiency and drug release from liposome preparations, and establishing drug product specifications are all crucial for drug development.

Based on our comprehensive liposome platform, BOC Sciences uses a variety of technologies for liposome analysis to support drug development.

What Do We Do?

  • Physicochemical Properties
    • Determine particle size and polydispersity index (PDI)
    • The particle size and distribution of liposomes are important parameters affecting drug loading, which determines the drug pharmacokinetics and pharmacodynamics in circulation and the stability of the liposome solution.

    • Zeta Potential
    • The measurement of liposome Zeta potential can provide insights into liposome stability, circulation time, protein interactions, granular cell permeability, and biocompatibility. By circumventing surface charge correlation, the biological properties of liposomes can be improved.

  • Encapsulation Efficiency
  • Encapsulation efficiency is one of the important parameters for assessing a drug delivery system. Drug encapsulation efficiency can be determine by the amount of drug contained in the liposome and comparing it with the total drug and liposome drug loading.

  • In Vitro Drug Release
  • Liposomal drug release kinetics is a prerequisite for establishing a correlation between in vitro and in vivo studies of liposome drugs. Our team has adopted a series of analytical methods to better understand the drug release kinetics, such as the response to pH, temperature, the addition of excipients, changes in salt concentration.

  • Stability Testing
  • Stability studies help overcome obstacles to the widespread use of liposomes. We determine liposome product stability under specific conditions.

  • Product Specification
  • We analyze of a range of parameters for liposome drug product specifications.

  • Active Pharmaceutical Ingredients (APIs) Analysis
  • Drug ingredients are also key to liposomal drug products. The characteristics of API also contribute to the stability of liposome drugs.
