Unique synthesis process: Made of N-vinylpyrrolidone (NVP) through free radical solution polymerization.
Excellent biocompatibility: Molecular structure is similar to protein model, with good chemical stability, excellent physiological safety, and no irritation to human skin, mucous membranes, eyes, etc.
Accurate drug release: The degree of polymerization and cross-linking can be adjusted according to needs to achieve precise control of drug release rate.
Wide range of dosage form adaptation: Good solubility and plasticity, suitable for oral preparations, injections, eye drops, topical medicines and other drug dosage forms.
FAQ
What are the differences in the application scenarios of NVP homopolymers with different molecular weights in drug encapsulation?
Low molecular weight products have better water solubility and are suitable for rapid dissolution encapsulation of oral liquid preparations; high molecular weight products have good film-forming properties and are mostly used for encapsulation of long-acting drug delivery systems such as sustained-release patches and microspheres.
For special dosage forms (such as ocular implants), can customized products be provided?
The degree of cross-linking and particle size distribution can be adjusted according to dosage form requirements.
Do you provide technical support for drug compatibility testing?
The technical team can assist in conducting compatibility tests with various active ingredients (such as proteins and small molecule chemical drugs) and provide full support including stability data interpretation.
