IHypromellose, eyaziwa nangokuthi i-hydroxypropyl methylcellulose (HPMC), i-polymer yokwenziwa etholakala ku-cellulose. Isetshenziswa kakhulu ezimbonini ezahlukahlukene, kufaka phakathi ezemithi, izimonyo, nemikhiqizo yokudla. Emithi, i-hypromellose inezicelo eziningana ngenxa yezakhiwo zayo eziyingqayizivele.
1. Isingeniso se-Hypromellose:
I-Hypromellose iyi-polymer eyi-hydrophilic eyenza isixazululo esisobala, esibonakalayo lapho sincibilika emanzini. Ivamise ukusetshenziswa njengesithako esingasebenzi ekwakhiweni kwemithi ukuze kuthuthukiswe izici zomkhiqizo ezifana ne-viscosity, ukuzinza, nokutholakala kwe-bioavailability. I-Hypromellose isetshenziswa kabanzi kumafomu womthamo oqinile womlomo, amalungiselelo e-ophthalmic, kanye nokwakhiwa kwezihloko.
2. Izicelo Zemithi:
a. Amafomu Esilinganiso Esiqinile Somlomo:
Emithi yomlomo, i-hypromellose inezinjongo ezihlukahlukene:
I-Binder: Isiza ukuhlanganisa izithako zemithi (ama-API) ezisebenzayo ukwenza amaphilisi noma amaphilisi.
I-Disintegrant: I-Hypromellose yenza kube lula ukuhlukana kwamaphilisi noma amaphilisi emgudwini wamathumbu, ikhuthaza ukukhululwa kwezidakamizwa nokumuncwa.
Ifilimu Yangaphambili: Isetshenziselwa ukwakha ifilimu elizacile, elivikelayo kumathebulethi ukuze kwenziwe ukukhishwa okulawulwayo noma ukufihla okungathandeki.
b. Amalungiselelo e-Ophthalmic:
Emaconsi esweni namafutha okugcoba, i-hypromellose isebenza njenge:
I-Viscosity Modifier: Yandisa i-viscosity yamaconsi wamehlo, inikeze isikhathi eside sokuthintana nendawo ye-ocular futhi ithuthukisa ukulethwa kwezidakamizwa.
I-Lubricant: I-Hypromellose igcoba ubuso beso, ikhulule ukoma nokungakhululeki okuhambisana nezimo ezifana nesifo samehlo esomile.
c. Amafomula wezihloko:
Emikhiqizweni ye-topical efana nokhilimu, ama-gel, namafutha okugcoba, i-hypromellose yenza kanje:
I-Gelling Agent: Isiza ukwakha ukuvumelana okufana nejeli, ukuthuthukisa ukusabalala nokunamathela komkhiqizo esikhumbeni.
I-Moisturizer: I-Hypromellose igcina umswakama, ithambisa isikhumba futhi ivimbele ukulahleka kwamanzi.
3. Indlela Yesenzo:
Indlela yokusebenza ye-Hypromellose incike ekusetshenzisweni kwayo:
Ukulawulwa Komlomo: Uma idliwe, i-hypromellose ikhukhumala lapho ithintana namanzi emgudwini wamathumbu, ikhuthaze ukuhlakazeka kanye nokuqedwa kwefomu lomthamo. Lokhu kuvumela ukukhululwa okulawulwayo kanye nokumuncwa kwemithi.
Ukusetshenziswa kwe-Ophthalmic: Emaconsi esweni, i-hypromellose inyusa i-viscosity yesisombululo, yandisa isikhathi sokuthinta i-ocular futhi ithuthukisa ukumuncwa kwezidakamizwa. Iphinde inikeze ukugcoba ukukhulula ukoma nokucasuka.
I-Topical Application: Njenge-ejenti ye-gelling, i-hypromellose yenza ungqimba oluvikelayo esikhumbeni, ukuvimbela ukulahlekelwa umswakama futhi kube lula ukumuncwa kwezithako ezisebenzayo.
4. Iphrofayela Yokuphepha:
I-Hypromellose ngokuvamile ibhekwa njengephephile ukuthi isetshenziswe emikhiqizweni yemithi, izimonyo, nemikhiqizo yokudla. Ayinabuthi, ayicunuli, futhi ayiyona i-allergenic. Kodwa-ke, abantu abane-hypersensitivity eyaziwayo kokuphuma kwe-cellulose kufanele bagweme imikhiqizo equkethe i-hypromellose. Ukwengeza, amaconsi iso aqukethe i-hypromellose angase abangele ukufiphala kwesikhashana kombono ngokushesha ngemva kokuphathwa, okuvamise ukuxazulula ngokushesha.
5. Imithelela Engenzeka Engase Ivele:
Nakuba i-hypromellose ibekezelelwa kahle abantu abaningi, eminye imiphumela emibi engavamile ingase yenzeke, kuhlanganise:
Ukungezwani nokungezwani nomzimba: Kubantu abazwelayo, ukuzwela okukhulu njengokulunywa, ububomvu, noma ukuvuvukala kungase kwenzeke lapho ubhekene nemikhiqizo equkethe i-hypromellose.
Ukucasuka kwe-Ocular: Amaconsi esweni aqukethe i-hypromellose angabangela ukucasuka okuncane, ukuvutha, noma ukuluma lapho kufakwe.
Ukuphazamiseka Kwamathunjini: Ezimweni ezingavamile, imithi yomlomo equkethe i-hypromellose ingabangela izimpawu zamathumbu ezinjengokucanuzela kwenhliziyo, ukuqunjelwa, noma isifo sohudo.
I-Hypromellose iyi-polymer eguquguqukayo esebenza ngezindlela ezihlukahlukene zemithi, okuhlanganisa amafomu omthamo oqinile womlomo, amalungiselelo e-ophthalmic, kanye nokwakheka kwezihloko. Ithuthukisa izici zomkhiqizo ezifana ne-viscosity, ukuzinza, kanye ne-bioavailability, ukuthuthukisa ukulethwa kwezidakamizwa nokuthobela isiguli. Naphezu kokusetshenziswa kwayo okubanzi kanye nephrofayili yokuphepha evumayo ngokuvamile, abantu abane-hypersensitivity eyaziwa kokuphuma kokuphuma ku-cellulose kufanele basebenzise imikhiqizo equkethe i-hypromellose ngokuqapha. Sekukonke, i-hypromellose idlala indima ebalulekile ekwenziweni kwemithi yesimanje, inikele ekusebenzeni nasekuphepheni kwemithi nemikhiqizo yokunakekelwa kwempilo.
