I-HEC (i-Hydroxyethyl Cellulose)iyi-polymer evamile encibilika emanzini esetshenziswa kabanzi ekulungiseleleni imithi. Iwumkhiqizo we-cellulose, otholakala ngokusabela i-ethanolamine (i-ethylene oxide) ne-cellulose. Ngenxa yokuncibilika kwayo okuhle, ukuzinza, ikhono lokulungisa i-viscosity kanye nokuhambisana kwayo nezinto eziphilayo, i-HEC inezinhlobo eziningi zezicelo emkhakheni wemithi, ikakhulukazi ekuthuthukisweni kokwakheka, ukwakheka kwefomu lomthamo kanye nokulawulwa kokukhishwa kwemithi kwemithi.
1. Izakhiwo eziyisisekelo ze-HEC
I-HEC, njenge-cellulose eguquliwe, inezakhiwo ezilandelayo eziyisisekelo:
Ukuncibilika kwamanzi: I-AnxinCel®HEC ingakha isixazululo esiqinile emanzini, futhi ukuncibilika kwayo kuhlobene nokushisa kanye ne-pH. Lesi sici senza ukuthi isetshenziswe ngezindlela ezahlukene zomthamo njengokusetshenziswa ngomlomo kanye nokusetshenziswa kwangaphandle.
Ukuhambisana kwezinto eziphilayo: I-HEC ayinabo ubuthi futhi ayicasuli emzimbeni womuntu futhi iyahambisana nemithi eminingi. Ngakho-ke, isetshenziswa kabanzi ezinhlotsheni zomthamo ezikhishwa njalo kanye nezinhlobo zomthamo wokuphathwa kwendawo wemithi.
Ukuqina Okulungisekayo: Ukuqina kwe-HEC kungalungiswa ngokushintsha isisindo sayo sama-molecule noma ukuhlushwa, okubalulekile ekulawuleni izinga lokukhishwa kwemithi noma ekuthuthukiseni ukuzinza kwemithi.
2. Ukusetshenziswa kwe-HEC emithini yokwelapha
Njengesithako esibalulekile ekulungiseleleni imithi, i-HEC inemisebenzi eminingi. Nazi izindawo eziyinhloko zokusetshenziswa kwayo ekulungiseleleni imithi.
2.1 Ukusetshenziswa ekulungiseleleni ngomlomo
Ezinhlotsheni zomthamo womlomo, i-HEC ivame ukusetshenziswa ekukhiqizweni kwamaphilisi, ama-capsule kanye namalungiselelo oketshezi. Imisebenzi yayo eyinhloko ihlanganisa:
I-Binder: Kumaphilisi kanye nama-granules, i-HEC ingasetshenziswa njenge-binder ukuze ihlanganise kangcono izinhlayiya zemithi noma izimpushana ndawonye ukuqinisekisa ukuqina nokuqina kwamaphilisi.
Ukulawulwa kokukhululwa okuqhubekayo: I-HEC ingafinyelela umphumela wokukhululwa okuqhubekayo ngokulawula izinga lokukhululwa komuthi. Uma i-HEC isetshenziswa kanye nezinye izithako (njenge-polyvinyl pyrrolidone, i-carboxymethyl cellulose, njll.), ingandisa isikhathi sokukhululwa komuthi emzimbeni ngempumelelo, inciphise imvamisa yomuthi, futhi ithuthukise ukuthobela kwesiguli.
Isiqinisi: Emalungiselelweni okuphuza uketshezi, i-AnxinCel®HEC njengesiqinisi ingathuthukisa ukunambitheka komuthi kanye nokuqina kwefomu lomthamo.
2.2 Ukusetshenziswa ekulungiseleleni izinto ezisetshenziswayo
I-HEC isetshenziswa kabanzi ekugcotshweni kwangaphandle, okhilimu, amajeli, ama-lotion kanye neminye imithi, idlala indima eminingi:
I-gel matrix: I-HEC ivame ukusetshenziswa njenge-matrix yama-gel, ikakhulukazi ezinhlelweni zokulethwa kwemithi ye-transdermal. Inganikeza ukuvumelana okufanele futhi yandise isikhathi sokuhlala komuthi esikhumbeni, ngaleyo ndlela ithuthukise ukusebenza kahle.
Ukuqina kanye nokuqina: Ukuqina kwe-HEC kungathuthukisa ukunamathela kwemithi esikhumbeni futhi kuvimbele umuthi ukuthi ungawi ngaphambi kwesikhathi ngenxa yezici zangaphandle njengokungqubuzana noma ukugeza. Ngaphezu kwalokho, i-HEC ingathuthukisa ukuqina kwama-creams namafutha okugcoba futhi ivimbele ukuqhekeka noma ukwakheka kwamakristalu.
Isithambisi kanye nesithambisi: I-HEC inezakhiwo ezinhle zokuthambisa isikhumba futhi ingasiza ekugcineni isikhumba simanzi futhi sivimbele ukoma, ngakho-ke isetshenziswa nasezithambisini kanye neminye imikhiqizo yokunakekela isikhumba.
2.3 Ukusetshenziswa kumalungiselelo amehlo
Ukusetshenziswa kwe-HEC kumalungiselelo amehlo kubonakala kakhulu endimeni yayo njenge-glue kanye ne-lubricant:
Amajeli e-Ophthalmic namaconsi eso: I-HEC ingasetshenziswa njengesinamathelisi sokulungiselela amehlo ukuze kwandiswe isikhathi sokuxhumana phakathi komuthi neso futhi kuqinisekiswe ukusebenza kahle komuthi. Ngesikhathi esifanayo, i-viscosity yayo ingavimbela futhi ukuwa kwamehlo ekulahlekelweni ngokushesha okukhulu futhi yandise isikhathi sokugcinwa komuthi.
Ukugcoba: I-HEC inomswakama omuhle futhi ingahlinzeka ngokugcoba okuqhubekayo ekwelapheni izifo zamehlo ezifana namehlo omile, okunciphisa ukungakhululeki kwamehlo.
2.4 Ukusetshenziswa kumalungiselelo omjovo
I-HEC ingasetshenziswa futhi ekulungiseleleni amafomu omthamo womjovo, ikakhulukazi emijovweni esebenza isikhathi eside kanye nemithi yokukhulula isikhathi eside. Imisebenzi eyinhloko ye-HEC kula malungiselelo ihlanganisa:
Isiqinisi kanye nesiqinisi: Kujova,I-HECkungandisa ukujiya kwesisombululo, kwehlise ijubane lokujova komuthi, futhi kuthuthukise ukuzinza komuthi.
Ukulawula ukukhishwa kwemithi: Njengenye yezingxenye zesistimu yokukhululwa okuqhubekayo kwemithi, i-HEC ingalawula izinga lokukhishwa kwemithi ngokwenza ungqimba lwejeli ngemva kokujova, ukuze kufezwe injongo yokwelashwa kwesikhathi eside.
3. Indima ye-HEC ezinhlelweni zokulethwa kwezidakamizwa
Ngokuthuthuka kobuchwepheshe bemithi, i-HEC isetshenziswe kabanzi ezinhlelweni ezahlukene zokulethwa kwemithi, ikakhulukazi emikhakheni yabathwali bemithi emincane, ama-microspheres, kanye nabathwali bemithi abakhishwa njalo. I-HEC ingahlanganiswa nezinto ezahlukahlukene zokuthwala imithi ukuze kwakheke inhlanganisela eqinile ukuqinisekisa ukukhishwa okuqhubekayo kanye nokulethwa ngempumelelo kwemithi.
Isithwali semithi ye-Nano: I-HEC ingasetshenziswa njengesiqinisi sabathwali bemithi ye-nano ukuvimbela ukuhlangana noma ukuna kwezinhlayiya zesithwali futhi kwandise ukutholakala kwemithi.
Ama-Microsphere nezinhlayiya: I-HEC ingasetshenziswa ukulungiselela ama-microsphere kanye nabathwali bezidakamizwa zama-microparticle ukuqinisekisa ukukhishwa kancane kwemithi emzimbeni nokuthuthukisa ukusebenza kahle kwemithi.
Njengomhlanganyeli wemithi osebenza kahle futhi osebenzayo, i-AnxinCel®HEC inamathuba amaningi okusetshenziswa ekulungiseleleni imithi. Ngokuthuthuka okuqhubekayo kobuchwepheshe bemithi, i-HEC idlala indima ebaluleke kakhulu ekulawuleni ukukhishwa kwemithi, ukuphathwa kwendawo, ukulungiswa kokukhishwa okuqhubekayo kanye nezinhlelo ezintsha zokulethwa kwemithi. Ukuhambisana kwayo okuhle kwezinto eziphilayo, ukujiya okulungisekayo kanye nokuqina kwenza ingenakufakwa esikhundleni sayo emkhakheni wezokwelapha. Esikhathini esizayo, ngocwaningo olujulile lwe-HEC, ukusetshenziswa kwayo ekulungiseleleni imithi kuzoba kubanzi futhi kuhlukahlukene.
