Nei HpMC ichishandiswa mufirimu yekufamba?

Firimu rinobatanidza tekinoroji rinoshandiswa zvakanyanya muindasitiri yemishonga, kunyanya mukugadzirwa kwemishonga yemuromo. Mafirimu ekucheka haakwanise kungovandudza kutaridzika kwemishonga, asi zvakare kuvandudza kugadzikana kwezvinodhaka, kudzora chiyero chekuburitsa, chifukidze kunhuhwirira kwakashata kana kushungurudzika kwemishonga, uye kuvandudza kutevedzera murwere. Pakati pavo, hydroxyprupyl methylcellose (HPMC), sechinhu chakajairika chekubatanidza, chave chimwe chezvinhu zvakakosha mufirimu kuungana nekuda kwekuita kwayo kwakanaka uye kuenderana kwakanaka.

1. Basic Properties yeHPMC
HPMC ndeye polymer yakawanikwa yakawanikwa nemakemikari kugadziridzwa kwemasikirwo emusikirwo cellulose. Izvo zvinonyanya kuwanikwa ne cellulose mushure mekurapa kwehydroxypropropyl uye methylation kurapwa, uye ine yakanaka mvura solubility uye biocomputer. Iyo Solubility neViscosity yeHPMC mumvura inogona kudzorwa nekugadzirisa chimiro charo chemanyorose, kuti inogona kuenderana nezvinodiwa zvakasiyana. Mukuwedzera, HPMC ine yakanaka yekugadzirisa, makemikari kugadzikana uye biodergradability, uye haina chepfu uye chisina kujairika uye chisina kukuvadza, kusangana nezvinodiwa zvezvinodhaka.

2. Zvakanakira HPMC sekufamba kwefirimu
2.1 yakanaka firimu-yekugadzira zvinhu
HPMC ine yakanaka firimu-yekuumba midziyo. Mushure mekunyungudika, HPMC inogona kukurumidza kuumba yunifomu firimu remuvhu pamusoro pehomwe, uye simba remafirimu, kusimba uye kujeka zvese zvakanaka. Izvi zvinobvumidza kuve nechokwadi chekutaridzika kwechisimba kana chakashandiswa sechinhu chinobatanidza, wedzera kukwezva kwemushonga, uye zvakare kuwedzera mashandiro emushonga mumuviri.

2.2 Kudzorerwa Kuburitswa Kugadziriswa
HPMC ine hunhu hwekudzora huwandu hwekuburitswa zvinodhaka, uye zvinoshandiswa zvakanyanya mukugadzirira kudzorwa kusunungurwa. HPMC yashandiswa sechikamu cheiyo firimu yekuvhara, inogona kudzora chiyero chekuburitsa chemushonga kuburikidza nehydration yefirimu. Kunyanya mune gadziriro yemuromo, iyo inokatyamadza inogona kukanganisa maitiro emushonga, nekudaro achizadzisa kuburitswa kwekusunungurwa kana kudzorwa mushonga mumushonga wegakava. Semuenzaniso, HPMC inogona kusunungura zvinodhaka nekunyora mvura nekuzvimba muguruva rekusvitsa mushonga, uye kudzivisa kuburitswa kwemushonga munguva pfupi, nekukasira kuvandudza maitiro ekurapa uye kuderedza mhedzisiro.

2.3 Zvinobatsira kugadzikana kwezvinodhaka
HPMC yekubatanidza inogona kudzivirira zvinobudirira zvinodhaka zvinodhaka uye kudzivirira kubva mukushatisa kana oxidation munzvimbo dzekunze, kunyanya kune zvinodhaka zvine unyoro, mwenje kana mhepo. Chisungo chekushamisika chakaumbwa nefirimu rekubatanidza rinogona kuita zvinobudirira zvinodhaka kubva mukubata kunze kwenzvimbo uye kuderedza kusagadzikana kwemushonga. Semuenzaniso, HPMC inogona kudzivirira iyo pesvedzero yemanyoro uye mhepo pane zvinodhaka, nokudaro ichivandudza kugadzikana kwekuchengetedza mushonga.

2.4 Kuvandudza kutaridzika uye kuravira kwemushonga
HPMC ine transpency yakanaka, iyo inogona kuita kuti pamusoro penyaya dzakatsiga uye glossy, wedzera runako rwemushonga, uye uvandudze kugamuchirwa kwemurwere. Mukuwedzera, HPMC inogona zvakare kufukidza iyo shungu kana kuti inonhuwira yemushonga uye ichivandudza kuravira kwemushonga. Kunyanya kune zvimwe zvinodhaka zvine kuravira kwakashata, zvakadai sekurwisa mabhakitiriya kana zvimwe zvinogadzirira, kushandiswa kweHPMC kunogona kuvandudza zvakanyanya mishonga yemurwere, kunyanya muvana nevarwere vakwegura, uye vandudze kutevedzera murwere.

2.5 BiocompriChigiribility uye kuchengeteka
HPMC inotorwa kubva kune yakasikwa cellulose, ine yakanaka biocompany uye biodergradability, uye haina kukonzera zvinhu zviri pachena mumuviri wemunhu. Naizvozvo, HPMC inogona kushandiswa zvakachengeteka mukugadzirwa kwemishonga yemuromo senge firimu inovhara zvinhu pasina mikana yakaipa pamuviri wemunhu. Iyo ine kushatirisa kushoma kune gastrointestinal turakiti uye haizokonzere mutoro wakakosha pamuviri wemunhu mushure mekushandisa.

2.6 yakakura mhando dzezvishandiso
HPMC sechinhu chinokonzeresa zvinhu zvakakodzera kugadzirwa kwemhando dzakasiyana siyana, kunyanya mune dzakasiyana gadziriro dzemishonga, HPMC inogona kugadzirisa yayo yekushandisa uye yekunyungudika maererano nezvinodiwa chaizvo. Izvi zvinoita kuti HPMC yakanyanyisa kuchinja uye kujaira, uye inogona kusangana nezvido zvekubatanidza zvinodhaka zvakasiyana. Kunyangwe iyo yakasimba masisitimu, mapiritsi, kana makapu, HPMC inogona kushandiswa kuunganidza.

3. Mienzaniso yekushandisa yeHPMC Firimu Coating
Mune zvinoshandiswa zvinoshanda, HPMC inoshandiswa zvakanyanya seye firimu inovhara zvinhu mune dzakasiyana siyana gadziriso yemishonga. Semuenzaniso, mukugadzirira vamwe vasingapiwi-steroidal zvinodhaka (NSAIDS) seIbuprophen uye acetaminophefen, HPMC Firimu Coating inowanzoshandiswa kusunungurwa uye kuderedza kushatirisa kune gastrointestared turakiti. Pamusoro pezvo, kune yakanangidzirwa kusunungurwa kwemamwe mishonga, HPMC inoshandiswawo mukusimudzira kwekusunungurwa kana kusunungura mishonga, etcancess-svina

Seye firimu inovhara zvinhu, HPMC ine zvisinga tsanangurike zvakanakira kugadzirira kweMishonga. Izvo hazvingopa chete zvivakwa zvemweya zvakanaka uye kugadzikana, asi zvakare zvinodzora chiyero chekusunungura zvinodhaka, chinovandudza kuravira uye kuoneka kwemishonga, uye nekuwedzera murwere kutevedzera. HPMC's Biocomputer, isina kujairika, uye kushandurwa kwakanaka kunoita kuti ive yakakosha chikamu chemazuva ano zvinodhaka zvinobatanidza tekinoroji. Mune zvinodhaka zvinodhaka
