Kuona kuchena kwe hydroxyprupyl methylcellose (HPMC) inoshandiswa mune mishonga uye chikafu chakakosha chekuchengetedza kuchengeteka, kushanda uye maitiro emhando. HPMC inozoshandiswa zvakanyanya sedanda, kuunganidza mumiririri, firimu-raimbova mumiririri, uye seyekudzora-mishonga, stabilizer, uye emulsifier mune zvigadzirwa zvekudya. Hezvino zvinhu zvakakosha kuti uve nechokwadi chekuchena kwayo:
1. Raw zvinyorwa zvemhando
1.1 kunobva cellulose:
Iko kuchena kweHPMC kunotanga nemhando yeiyo cellulose yaishandisa. Cellulose inofanira kutorwa kubva kune isiri-gotoni kana huni yemapuranga iyo yakasununguka kubva kuzvimisikidzwa kwakadai semishonga yekuuraya zvipuka, simbi inorema, uye kumwe kusviba.
1.2 kuwirirana kugovera ketani:
Kuverengera yakavimbika uye inowanzoenderana sosi yepamusoro-mhando cellulose yakakosha. Vatengesi vanofanira kubviswa zvakakwana, uye kupa maketani anofanirwa kuve pachena uye anotaridzika kudzivisa chero kupombirwa kana kutsiva kwezvinhu.
2. Kugadzira maitiro
2.1 Zvakadzora Nzvimbo:
Maitiro ekugadzira anofanirwa kuitwa munzvimbo inodzorwa inosimbisa maitiro akanaka ekugadzira (GMP). Izvi zvinosanganisira kuchengetedza zvakachena uye kushandisa zvishandiso zvinoderedza njodzi yekusvibiswa.
2.2 Kushandiswa kwemishonga-giredhi makemikari:
Iwo makemikari anoshandiswa mukugadziridzwa kwemherem cellulose kuti abudise HPMC, akadai methyl chloride uye profilyxo oxide, anofanira kunge ari wegiredhi rechikadzi kana rekudya kuti adzivise kusuma kwekukuvadza.
2.3 Maitiro ekubvumidzwa:
Nhanho yega yega yeiyo yekugadzira inofanirwa kuve yakasimbiswa kuve nechokwadi chekuti inogara ichigadzira HPMC yeiyo yakavanzika uye mhando. Izvi zvinosanganisira kudzora mamiriro ekuita, sekupisa, Ph, uye kuita nguva.
3. Schention Matanho
3.1 Kugeza uye Filtration:
Kutumira-kuita, kunyatso kugeza uye matanho emigwagwa anodiwa kubvisa chero makemikari asina kugadziriswa, zvigadzirwa, uye zvimwe zvisina kunaka. Kushambadzira kwakawanda nemvura yakacheneswa kunogona kuwedzera kubviswa kwekusvibisa kusvibiswa.
3.2 Solvent Ongororo:
Mune zvimwe zviitiko, nzira solinction yekutsvedza inoshandiswa kubvisa kusiri-kwemvura-kusviba kusvibiswa. Iko kusarudzwa kwe solvent uye maitiro ekutsamwa anofanirwa kunyatso kudzorwa kuti arege kuzviisa kusvibiswa kutsva.
4. Kuongororwa kwekuongorora
4.1 Kusachena Kusvibisa:
Kuedzwa kwakazara kwekusachena, kusanganisira zvakasara sol sol sol sol, simbi huru, kusvibiswa kwemicrobial, uye endotoxins, kwakakosha. Nhungamiro dzakadai seGasi Chromatography (GC), High-Performangraphy chromatography (HPLC), uye inductively Colled Plasma Massma SpectRometry (ICP-ms) inowanzoshandiswa.
4.2 Kutaura Kwekutaura Kwakakosha:
HPMC inofanirwa kusangana nezvayo yemapakecopecial zviyero (senge USP, EP, JP) iyo inotsanangudza miganhu inogamuchirika yekusagadzikana kwakasiyana siyana. Kugara uchiedza kuedzwa kunoita kuti chigadzirwa chinoenderana neiyi yakatarwa.
4.3 Kuenderana Cheki:
Kuenderana muViscosity, degree rekutsiva, uye molecular uremu kugoverwa kunofanirwa kuongororwa kuti uve nechokwadi cheBatch-kusvika-batch zvakafanana. Chero zvipi zvipi zvingaitwe zvinogona kuratidza zvinogona kusvibiswa kana kuita nyaya.
5. Kutakura uye kuchengetedza
5.1 Kusvibiswa-kusununguka kurongedza:
HPMC inofanira kurongedzwa mukusvibiswa-isina, inert midziyo inodzivirira kubva kune zvakatipoteredza zvinhu zvakadai sekunyorova, mhepo, uye mwenje, izvo zvinogona kukanganisa mhando yayo.
5.2 Mamiriro ekuchengetedza ekuchengetedza:
Mamiriro ezvinhu ekuchengetedza akakodzera, kusanganisira tembiricha uye ekunyanyisa kudzora, akakosha kudzivirira kusvibiswa kana kusvibiswa kweHPMC. Nzvimbo dzekuchengetedza dzinofanira kuve dzakachena, dzoma, uye dzinochengetwa pamamiriro ezvinhu akakodzera.
6. Regulatory kutevedzera
6.1 Kuomerera kune mirau:
Kuteerana neInternational Regulatory zviyero (FDA, EMA, E,C.) Kunovimbisa kuti HPMC yakagadzirwa, yakaedzwa, uye inogadziriswa maererano nemhando yepamusoro yemhando yepamusoro.
6.2 Zvinyorwa uye Kuongorora:
Kuchengeta zvinyorwa zvakadzama uye kuteedzana kweiyo yega batch yeHPMC inokosha. Izvi zvinosanganisira zvinyorwa zvezvinyorwa zvehuni, zvigadzirwa, kuyedza mhedzisiro, uye kugovera.
7. Supporter Kukodzera
7.1 Rove Supporter Audits:
Kuitisa nguva nenguva dzekutengesa kwevatengesi kuti vave nechokwadi chekuti vanoomerera kune hunhu hwemhando uye zviito zveGMP zvakakosha. Izvi zvinosanganisira kuratidza yavo yemhando yekudzora masisitimu, maitiro ekugadzira, uye mbichana zvinyorwa zvekunaka.
7.2 Supporter performance yekutarisa:
Kuenderera mberi kwekutarisa kwekutengesa kwekutengesa, kusanganisira mhinduro zvishambadziro uye kururamisa matanho maitiro, kunobatsira kuchengetedza kutendeka kweketani yekupa.
8. Hunhu Kudzora uye Chivimbiso
8.1 In-House House Control:
Kugadzira Rosugust In-House House Control Laboratories Yakagadzirirwa neNyika-ye-iyo-iyo-iyo Art nhumbu zviridzwa zvichiita kuti uenderere mberi nekutarisa uye kuongororwa kweHPMC.
8.2 Yetatu-Bato Kuedzwa:
Kubatanidza kwakazvimirira kwechitatu-bato remabhiza ekuedzwa kwenguva pfupi kunogona kupa imwe ivimbiso yekuvimbiswa kwekuchena uye mhando yeHPMC.
8.3 Kuenderera mberi kuvandudza:
Kuita chirongwa chekuvandudza kunoenderera kunowongorora uye kunowedzera maitiro emhando yepamusoro kunobatsira mukuchengetedza miitiro yakakwirira uye kugadzirisa chero zvinhu zvinobuda zvakanaka.
9. Kudzidziswa kwevashandi
9.1 Kudzidziswa kwakazara kwezvirongwa:
Kudzidzisa vashandi paGMP, maitiro ekushanda ekushanda (SPOS), uye kukosha kwekuchena mumidziyo yemishonga uye yekudya-giredhi kwakakosha. Vashandi vakanyatsodzidziswa havakwanisi kuita zvikanganiso zvinogona kukanganisa kuchena.
9.2 Kuziva uye Mutoro:
Kusimudzira tsika yemhando uye mutoro pakati pevashandi kunovabatsira kuti munhu wese anoziva basa ravo mukuchengetedza kuchena kweHPMC.
10. Njodzi yekutarisira
10.1 Hazard Ongororo:
Kuitisa nguva dzose njodzi kuongororwa kuti uzive uye kuderedza njodzi mukugadzira uye kugovera ketani matariro maitiro akakosha. Izvi zvinosanganisira kuongorora zvinogona kusvibiswa uye kutora matanho ekudzivirira.
10.2 Chiitiko Chekuita Mhinduro:
Kuve nechirongwa chechirume chekugadzirisa chekugadzirisa chero kusvibiswa kana nyaya dzemhando yepamusoro dzinoita kuti uve nekuchena kushoma pakuchena kwechigadzirwa chekupedzisira.
Nekutarisa pane izvi zvinhu zvakakosha, vagadziri vanokwanisa kuve nechokwadi chekuchena kwakanyanya kweHPMC inoshandiswa mumishonga uye chikafu, nekuchengetedza kutevedza hutano uye kuchengetedza kutevedzera zvine hunyanzvi hwemhando. Kuenderera mberi kusvinura, kuongororwa kwakawandisa, uye kuomerera kune maitiro akanakisa pakugadzirwa uye kupa ketani yakakosha kuwana uye kuchengetedza huwandu hwenzvimbo dzinodiwa dzeHPMC.
