Long-lasting performance. Among the microsphere products currently on the market, they can be sustained-released for up to half a year, which greatly improves patients' medication compliance by reducing the frequency of dosing.
Safety. The microspheres are slowly released at the administration site to maintain effective blood drug concentration, reduce blood drug concentration fluctuations, and reduce toxic and side effects. The polymer is a degradable excipient, which degrades into water and carbon dioxide in the body and is relatively safe.
Targeting. Microspheres can be targeted to specific tissues or organs by changing their size, shape, surface charge, or functional groups. This increases drug concentration at the site of action, reducing systemic exposure and adverse effects.
Professionalism. Microspheres have high technical barriers, high R&D costs, and long R&D cycles. In addition to solving the most basic problems of encapsulation efficiency and particle size uniformity, microsphere preparations also need to solve problems such as sterility assurance and process amplification in the production process. The depth of the technical moat can ensure that products are not easily broken by other companies and ensure technological advantages.
Potentiality. Microspheres are mainly used for peptide drugs. Compared with mature chemical drugs, peptide drugs have greater room for development and greater market potential.
Efficiency. The administration route of microspheres is injection, which bypasses the first-pass effect, improves bioavailability and reduces the dosage.
Controlled and sustained release. Microspheres can release drugs in a controlled and sustained manner according to the properties of the polymer, drug and environmental conditions. This can reduce the frequency of dosing for patients, enhance drug effects, and reduce drug side effects and toxicity.
Protect drugs. Microspheres can protect drugs from degradation, oxidation, or enzymatic hydrolysis by providing a physical barrier and a stable microenvironment. This can improve the stability and bioavailability of the drug and extend the shelf life of the formulation.
