High-viscosity, low-substituted pharmaceutical-grade HPMC forms a controlled-release system characterized by slower release, greater stability, and resistance to disintegration.
CELOPRE® MF4M can be used to including sustained-release tablets and controlled-release matrix tablets.
Its mechanism of action involves absorbing water and swelling to form a gel layer, thereby controlling the diffusion rate and release profile of the ایکٹو فارماسیوٹیکل اجزاء (API) to achieve a steady release of the drug.
CELOPRE® MF4M can be used to tablets with high drug loads, highly soluble APIs (prone to burst release), and applications requiring prolonged release over 12 or 24 hours.
Its key advantage lies in its ability to effectively control the release rate by forming a stable gel layer, thereby preventing drug dumping and achieving a smooth, sustained-release profile.
CELOPRE® MF4M can be used to including hydrophilic gel-matrix tablets, bilayer tablets, and complex controlled-release structures.
Its key advantage lies in its ability to absorb water and form a stable gel-matrix layer, thereby enabling precise control over the drug release rate; it is particularly well-suited for multilayer and irregularly shaped controlled-release designs.
