I-HPMC yezokwelapha

I-Hydroxypropylylylylylylylylylls (HPMC) ivame ukusetshenziswa embonini yezemithi njenge-excipient ekwakhekeni kwemithi ehlukahlukene. Ama-Execients yizinto ezingasebenzi ezingezwe ekwakhiweni kwemithi ezosiza enqubweni yokukhiqiza, athuthukise ukuqina kanye ne-bioavailability yezithako ezisebenzayo, futhi zithuthukise izici zonke zefomu lomthamo. Nakhu ukubuka konke kwezicelo, imisebenzi kanye nokucatshangelwa kwe-HPMC emithini:

1

1.1 Indima Ekunikezelweni Kwezemithi

I-HPMC isetshenziswa ekwakhiweni kwemithi njenge-multifunctionate excipient, okufaka isandla kwizakhiwo zenyama nangamakhemikhali zefomu lomthamo.

1.2 IZINZUZO E-APPICE YICEDIPE

• I-Binder: I-HPMC ingasetshenziswa njenge-binder ukusiza ukubopha isithako esisebenzayo semithi namanye ama-puscipients ndawonye ngokwakhiwa kwethebhulethi.
• Ukukhishwa okulondoloziwe: Amabanga athile e-HPMC aqashwa ukulawula ukukhishwa kwesithako esisebenzayo, okuvumela ukwakheka kokukhishwa okuqhubekayo.
• I-Film coating: I-HPMC isetshenziswa njenge-ejenti eyakha amafilimu ekuhlanganiseni kwamathebulethi, ukuhlinzeka ukuvikelwa, ukuthuthukisa ukubukeka, kanye nokwenza lula ukugwinya.
• Umenzeli wokuqina: Ukwakhiwa koketshezi, i-HPMC ingasebenza njenge-ejenti yokuqina ukuze kufezekiswe i-viscosity oyifunayo.

2. Imisebenzi ye-hydroxypropyllylylylylyl methyl celtule

2.1 I-Binter

Ngokwakhiwa kwethebhulethi, i-HPMC isebenza njenge-binder, isiza ukubamba ithebhulethi izithako ndawonye futhi inikeze ukuhlangana okudingekayo kokucindezelwa kwethebhulethi.

2.2 Ukukhishwa okuqhubekayo

Amanani athile we-HPMC aklanyelwe ukudedela isithako esisebenzayo kancane ngokuhamba kwesikhathi, okuvumela ukwakheka okukhethekile okuqhubekayo. Lokhu kubaluleke kakhulu ezidakamizweni ezidinga imiphumela yakudala yokwelapha.

2.3 Ifilimu yokuhlanganisa

I-HPMC isetshenziswa njenge-ejenti eyakha amafilimu ekuhlanganisweni kwamathebulethi. Ifilimu lihlinzeka ngokuvikelwa ithebhulethi, imaski ukunambitheka noma iphunga, futhi ithuthukisa isikhalazo esibukwayo sethebhulethi.

2.4 umenzeli wokuqina

Emakwakheni uketshezi, i-HPMC isebenza njenge-ejenti yokuqina, ilungisa ukubonwa kwesixazululo noma ukumiswa ukwenza lula ukudonswa nokuphatha.

3. Izicelo kwezokwelapha

3.1 amaphilisi

I-HPMC isetshenziswa kakhulu ekusungulweni kwethebulethi njenge-binder, ukuqhekeka, kanye ne-film coating. Kuyasiza ekucindezelweni kwethebhulethi Izithako futhi ihlinzeka ngokuhlobanisa ithebhulethi.

3.2 capsule

Kumakhiwo e-capsule, i-HPMC ingasetshenziswa njengesiguquli se-viscosity for the capsule okuqukethwe noma njengezinto zokubamba amafilimu zamakhompiyutha.

3.3 Ukwakheka kokukhishwa okuqhubekayo

I-HPMC iqashwa ekunikezelweni kokukhishwa okuqhubekayo ukulawula ukukhishwa kwesithako esisebenzayo, kuqinisekisa umphumela owedlule wezokwelapha.

3.4 ukwakheka koketshezi

Emithini ye-Liquid, njengokumiswa kwemininingwane noma isiraphu, imisebenzi ye-HPMC njenge-ejenti yokuqina, ethuthukisa ukubonakala kokwakhiwa kwe-dosing ethuthukisiwe.

4. Ukucatshangelwa kanye nokuqapha

4.1 Ukukhetha KweBanga

Ukukhethwa kwebanga le-HPMC kuncike kwizidingo ezithile zokwakhiwa kwemithi. Amabanga ahlukene angaba nezindawo ezahlukahlukene, njengokuvunywa, isisindo se-molecular, kanye nokushisa kwe-gelation.

4.2 Ukuvumelana Ukuvumelana

I-HPMC kufanele ihambisane namanye ama-Excipient kanye nesithako sezemithi esisebenzayo ukuze kuqinisekiswe ukuqina nokusebenza kwifomu lokugcina lomthamo.

4.3 Ukulandela umthetho wokulawula

Izakhi zemithi eziqukethe i-HPMC kumele zihambisane namazinga alawulayo kanye nemihlahlandlela ebekwe yiziphathimandla zezempilo ukuqinisekisa ukuphepha, ukusebenza ngempumelelo kanye nekhwalithi.

5. Isiphetho

IHydroxypropyllylylylylylylyllllulose iyinhlangano eguquguqukayo ye-Exsupiexes embonini yezemithi, efaka isandla ekwakhiweni kwamathebulethi, amaphilisi kanye nemithi ewuketshezi. Imisebenzi yayo ehlukahlukene, kufaka phakathi ukubopha, ukukhishwa okuqhubekayo, ukuhlanganiswa kwefilimu, nokuqina, kwenze kube yigugu ekwenzeni amandla okusebenza nezimpawu zamafomu ama-dosage emithi. Amakhemikhali kufanele acubungule ngokucophelela ibanga, ukuhambisana, kanye nezidingo zokulawula lapho kufakwa i-HPMC ekunikezelweni kwemithi.
