    I-Poly (Methylvinylether / Maleic Acid) Usawoti oxubile

    I-copolymer enikezwe ngefomu le-powder, incibilika kancane emanzini okuholela kuzixazululo ezinombala we-amber nge-viscosity ephezulu nokunamathela. Isetshenziswa njengesihlanganisi sokunamathisela kokufakelwa, futhi njenge-mucoadhesive yokulethwa kwezidakamizwa kolwelwesi lwamafinyila.Namabhuloho kasawoti weCalcium athuthukisa amandla okuhlangana.Amandla wokunamathela amahle kakhulu, Ukubamba okuhlala isikhathi eside, i-Mucoadhesive evumela ukulethwa kolwelwesi lwamafinyila. Ama-Paremeters Wobuchwepheshe Osemqoka: Ukubukeka Okumhlophe kuya kumanzi ayi-powder amhlophe ...
