METOLOSE® SR / TYLOPUR® SR
High-viscosity hypromellose for forming hydrophilic matrixes
The METOLOSE® SR/ TYLOPUR® SR range is used in the manufacture of hydrophilic matrixes for the sustained release of active ingredients. The METOLOSE® SR/ TYLOPUR® SR range from SHIN ETSU is compliant with Ph.Eur, JP and USP.
Hydrophilic matrixes
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/ TYLOPUR® SR range are used in hydrophilic matrixes to control the release of active substances in the body.
The products in the METOLOSE® SR/ TYLOPUR® 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
- Rapid hydration
The products in the METOLOSE® SR/ TYLOPUR® SR range can be used in direct compression or wet granulation.
Product range
The type of substitution for METOLOSE® SR/ TYLOPUR® 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.
