(HPMC) Ni irihe tandukaniro rifite cyangwa ridafite s?

Birasa nkaho bivugaHydroxyPropyl Methylcellse (HPMC), Polymenyo yakoreshejwe cyane mu nganda zinyuranye harimo na faruzi, kubaka, ibiryo, no kwisiga. Itandukaniro riri hagati ya HPMC hamwe kandi nta nyuguti 'irashobora kuba ifite amanota atandukanye, amashyi, cyangwa ibicuruzwa byihariye.

HydroxyPropyl Methylcellsellse (HPMC) ni igice cya kabiri, inert, polymer polymer yakomotse kuri selile. Mubisanzwe byakozwe binyuze mumiti ya selile, ikubiyemo kuvura selile hamwe na alkali na propayle kugirango utangire amatsinda ya hydroxyProppopy na methyl.

Hano hari ingingo zingenzi zerekeye HPMC:

Imiterere yimiti: HPMC igizwe n'iminyururu ndende yo guhuza glucose hamwe na hydroxyPropyl na methyl amatsinda ya metroxyl (-oh). Ikigereranyo cya aba basimbuye burashobora gutandukana, biganisha ku ntera zitandukanye za HPMC hamwe nimitungo itandukanye.

Ibintu byumubiri: HPMC ni ugushonga amazi kandi ikora neza, ibisubizo bya viscous mugihe yashonga mumazi. Ubukwe bwayo burashobora kugenzurwa no guhindura ibipimo nkibiro bya molecular, urwego rwo gusimbuza, no kwibanda.

Porogaramu:

Farumasiti: HPMC ikunze gukoreshwa mu miti ya farumasi nkumubyimba, binder, film yabanje, kandi imukozi nuwambereye mubisate, hamwe nibitera byingenzi.
Kubaka: Mu bikoresho by'ubwubatsi nk milliari, bitanga, na tile bifata neza, HPMC itezimbere ibikorwa, kugumana amazi, no kumeneka.
Ibiryo: HPMC ikoreshwa mubicuruzwa nkibibyimba, stabilizer, na emalifiriye. Bikunze kuboneka mubicuruzwa byamata, isosi, na dessert.
Kwisiga: HPMC ikubiye muri kwisiga no kwita ku kuntu ku giti cye nka cream, amavuta, na shampoos kugirango yongerera imiyoboro, itunganijwe, hamwe n'imitungo yo gukora film.

Inyungu:

HPMC itanga ibintu byiza byo kugumana amazi, aribyo byingenzi kubisabwa nka minisiteri ishingiye kuri sima ikenewe aho hyration ikenewe kugirango habeho gukira.
Itezimbere gupfumu no gukorana mubikoresho byubwubatsi, bitanga umusanzu mubikorwa byiza no kuramba.
Muri faruzi, HPMC yorohereza irekurwa ry'ibiyobyabwenge kandi yongerera ibintu bya tablet.
HPMC ifatwa nkumutekano kugirango ikore kandi yemerwa cyane mubiryo nibicuruzwa byo kwisiga.
Amanota n'ibisobanuro: HPMC iraboneka mu manota itandukanye no gusobanura bikwiranye na porogaramu zihariye. Ibi birimo itandukaniro muri viscosity, ingano yinshi, urwego rwo gusimbuza, hamwe nibindi bipimo kugirango byujuje ibisabwa ninganda zinyuranye.

Imiterere yubuyobozi: HPMC muri rusange izwiho umutekano (Gras) ukurikije inzego zishinzwe kugenzura nkibiryo byo mu biryo byo muri Amerika n'ibiyobyabwenge (FDA) igihe bikoreshwa hakurikijwe imikorere myiza.

HPMC ni polymer itandukanye hamwe nibisabwa bitandukanye munganda. Imitungo yayo irashobora guhuza kugirango yujuje ibisabwa byihariye, bigatuma ingirakamaro muburyo butandukanye. Niba ufite amakuru yihariye yerekeranye na HPMC hamwe cyangwa udafite inyuguti ', nyamuneka tanga inyongera kubisobanuro byagenewe.
