(HPMC) Ni irihe tandukaniro na S cyangwa idafite S?

Birasa nkaho urimo kuvugaHydroxypropyl Methylcellulose (HPMC), polymer ikoreshwa cyane mubikorwa bitandukanye birimo imiti, ubwubatsi, ibiryo, no kwisiga. Itandukaniro riri hagati ya HPMC hamwe ninyuguti 'S' irashobora kuba ijyanye n amanota atandukanye, formulaire, cyangwa ibicuruzwa byihariye.

Hydroxypropyl Methylcellulose (HPMC) ni igice cya sintetike, inert, viscoelastic polymer ikomoka kuri selile. Ubusanzwe ikorwa hifashishijwe uburyo bwo guhindura imiti ya selile, ikubiyemo kuvura selile hamwe na oxyde ya alkali na propylene kugirango itangize hydroxypropyl na methyl.

Hano hari ingingo z'ingenzi zerekeye HPMC:

Imiterere yimiti: HPMC igizwe numurongo muremure wa glucose hamwe na hydroxypropyl hamwe na methyl matsinda yometse kuri amwe mumatsinda ya hydroxyl (-OH). Ikigereranyo cyibi bisimbura kirashobora gutandukana, biganisha kumanota atandukanye ya HPMC hamwe nibintu bitandukanye.

Ibyiza bifatika: HPMC irashobora gushonga amazi kandi ikora ibisubizo bibonerana, bibonerana iyo bishonge mumazi. Ubukonje bwacyo burashobora kugenzurwa muguhindura ibipimo nkuburemere bwa molekile, urwego rwo gusimburwa, hamwe nibitekerezo.

Porogaramu:

Imiti yimiti: HPMC ikoreshwa muburyo bwa farumasi nkibibyimbye, binder, firime yahoze, kandi ikomeza-kurekura ibintu mubinini, capsules, hamwe nibisobanuro byingenzi.
Ubwubatsi: Mubikoresho byubwubatsi nka minisiteri, imashini, hamwe na tile, HPMC itezimbere imikorere, kubika amazi, no gufatira hamwe.
Ibiryo: HPMC ikoreshwa mubicuruzwa byibiribwa nkibibyimbye, stabilisateur, na emulifier. Bikunze kuboneka mubikomoka ku mata, amasosi, hamwe nubutayu.
Amavuta yo kwisiga: HPMC ishyirwa mubintu byo kwisiga hamwe nibicuruzwa byawe bwite nka cream, amavuta yo kwisiga, na shampo kugirango byongere ubwiza, ituze, hamwe nibikorwa bya firime.

Inyungu:

HPMC itanga uburyo bwiza bwo kubika amazi, ningirakamaro mubikorwa nka minisiteri ishingiye kuri sima aho bisabwa amazi maremare kugirango akire neza.
Itezimbere hamwe no gukora mubikoresho byubwubatsi, bigira uruhare mubikorwa byiza no kuramba.
Muri farumasi, HPMC yoroshya imiti igenzurwa kandi ikongera imiti igabanya ubukana.
HPMC ifatwa nk'umutekano mukoresha kandi iremewe cyane mubiribwa n'ibikoresho byo kwisiga.
Impamyabumenyi n'ibisobanuro: HPMC iraboneka mubyiciro bitandukanye nibisobanuro bihuye nibisabwa byihariye. Ibi birimo itandukaniro mubyiza, ingano yingingo, urwego rwo gusimbuza, nibindi bipimo kugirango byuzuze ibisabwa ninganda zitandukanye.

Imiterere igenga: HPMC isanzwe izwi nkumutekano (GRAS) ninzego zibishinzwe nk’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) iyo gikoreshejwe hakurikijwe uburyo bwiza bwo gukora.

HPMC ni polymer itandukanye ifite porogaramu zitandukanye mu nganda. Imiterere yacyo irashobora guhuzwa kugirango yuzuze ibisabwa byihariye, ikagira ikintu cyingirakamaro muburyo butandukanye no mubicuruzwa. Niba ufite amakuru yihariye yerekeye HPMC ufite cyangwa udafite inyuguti ya 'S', nyamuneka tanga ibisobanuro byinyongera kubisobanuro birambuye.
