Magnesium aluminometasilicate?

Magnesium aluminometasilicate is a porous, amorphous magnesium aluminum silicate used as a pharmaceutical excipient. It’s commonly sold under brand names like Neusilin (e.g., US2, US3).

Key points:
- What it is: a high-surface-area, porous silicate mineral that can adsorb liquids and drugs.
- Primary roles in tablets/c capsules:
- disintegrant: helps tablets break apart in the GI tract
- adsorbent/moisture control: binds water and liquids to improve stability and flow
- carrier for poorly soluble drugs or liquids (used in liquisolid systems)
- glidant/flow aid: improves powder flow and compressibility
- Why it’s used: enhances dissolution of poorly soluble drugs, improves tablet manufacture (flow, compression), and can enable liquid formulations to be turned into solids.
- Safety and regulatory: considered an inert pharmaceutical excipient with low systemic absorption; aluminum content is low; approved for use in many products (check the specific product’s data sheet and regulatory status for your region).
- Common grades: Neusilin US2, Neusilin US3 (different surface area and pore characteristics for various formulations).

If you want, tell me the context (e.g., optimizing a tablet formulation, solubility enhancement, regulatory questions), and I can tailor the guidance (including typical loading ranges and exact grade recommendations from manufacturer datasheets).
