The hydrophilic matrix?system is the simplest and cheapest controlled release technology for oral forms.
Comprised of a high-viscosity, water-soluble polymer (HPMC), the products in the METOLOSE? SR range are used in hydrophilic matrixes to control the release of active substances in the body.
The products in the METOLOSE? SR range have many properties:
- Gradual and controlled release of the active ingredient
- Control of the dissolution profile by:
- The percentage of HPMC in tablets
- Selection of viscosity
- Tablet size
- Simple and easy?matrix system for designing a formulation
- Good bioavailability
- Good compressibility
The products in the METOLOSE? SR range can be used in direct compression or wet granulation.
The type of substitution for METOLOSE? SR impacts the product's hydration and the strength of the gel formed.
The greater the viscosity, the stronger the gel and the slower the dissolution.

The products in the METOLOSE? SR range are manufactured in accordance with the Good Manufacturing Practices applicable to excipients.
