Copovidone e masani ona faʻaaogaina e pei o le vai-soluble fusifusia ma faʻamago faʻamau i le susu / tuusaʻo granulation faagasologa, e mafai foi ona faʻaaogaina e fai ma mea e fai ai ata.
* Suava faʻapipiʻi papamaa, talafeagai mo le susu pe mago granulation / faʻapipiʻi saʻo faiga.
*Film Mua: fa'apipi'iina ata tifaga mo le papamaa ma le suka e puipuia mai le vaeluaina, fa'aitiitia le susu ma maua ai le pipii lelei o ata.
