Typical usage ratio

• Blending at 0.1–5% w/w with other actives in granulation units, adjusted for target tablet or oral liquid strength
• Flexible to specific combination product labeling and registration requirements

Downstream process integration

• Charged to blending vessels with excipients and co-actives during wet or dry granulation
• Integrated into direct compression and tableting or into liquid suspension mixing for oral solutions
• Supports GMP traceability and in-process control documentation for batch release

Final product types

• Oral solid dose combination drugs (tablets, capsules)
• Combined-action oral syrups for cardiovascular support
• Multi-component hospital therapy packs

3. Analytical Reference and Diagnostic Reagent Manufacturing
