Kwishishini lamayeza, i-hypromellose (I-HPMC, METHOCEL™) ingasetyenziswa njenge-filler, i-binder, i-tablet coating polymer kunye ne-key excipient ukulawula ukukhululwa kwamayeza. I-Hypromellose ibisetyenziswa kwiipilisi kangangeminyaka engaphezu kwama-60 kwaye si-key excipient esetyenziswa kakhulu kwiipilisi ze-hydrophilic gel matrix.
Iinkampani ezininzi zamayeza zisebenzisa i-hypromellose ukukhupha amayeza alawulwayo, ingakumbi kwi-hydrophilic gel matrix tablet formulations. Xa kuziwa kwiimveliso ze-hypromellose, usenokuba uzibuza ukuba ungakhetha njani – ingakumbi ukuba ufuna into evumelana neelebheli kwaye ezinzileyo ukuze ithengiswe kubathengi bakho. Kwesi sikhokelo, siza kuthetha ngezinto ezibalulekileyo ekufuneka uzazi malunga ne-hypromellose.
Yintoni i-hypromellose?
IHypromellose, eyaziwa ngokuba yii-hydroxypropyl methylcellulose (HPMC), yipolymer esetyenziswa njengesithako samayeza ukulawula ukukhutshwa kwamayeza kwiipilisi ze-gel matrix ezisebenzisa amanzi amdaka.
IHypromellose yinto eyenziwe ngokwe-semi-synthetic ephuma kwi-cellulose, eyona polymer ininzi kakhulu kwindalo. Ezinye zeempawu zayo eziqhelekileyo ziquka:
iyanyibilika emanzini abandayo
ayinyibiliki emanzini ashushu
. Ayisiyoniyoniki
Inyibilika ngokukhetha kwizinyibilikisi zendalo
. Ukuguquguquka, iipropati zejeli yobushushu
Ukufuma kunye nokuqina komzimba ngaphandle kwe-pH
. I-Surfactant
ayisiyotyhefu
Incasa nevumba zithambile
Ukumelana nee-enzyme
. pH (2-13) uzinzo kuluhlu
Ingasetyenziswa njenge-thickener, i-emulsifier, i-binder, i-rate regulator, i-film yangaphambili
Yintoni iHydrophilic Gel Matrix Tablet?
Ithebhulethi ye-hydrophilic gel matrix yindlela yokulinganisa enokulawula ukukhutshwa kweziyobisi kwithebhulethi ixesha elide.
Ukulungiselela ithebhulethi ye-hydrophilic gel matrix:
. kulula kakhulu
Ifuna kuphela izixhobo zokucinezela iithebhulethi eziqhelekileyo
. Thintela ukulahlwa kwedosi yamayeza
Ayichaphazeleki bubulukhuni bethebhulethi okanye amandla okucinezelwa
Ukukhululwa kwamayeza kunokulungiswa ngokwenani lezinto ezincedisayo kunye neepolymers
Ukusetyenziswa kwe-hypromellose kwiipilisi ze-gel-matrix eziphila emanzini kuye kwavunywa kakhulu ngumthetho, kwaye i-hypromellose kulula ukuyisebenzisa kwaye inerekhodi elungileyo yokhuseleko, nto leyo ebonakaliswe zizifundo ezininzi. I-Hypromellose iye yaba lolona khetho lufanelekileyo kwiinkampani zamayeza ukuphuhlisa nokuvelisa iipilisi ezikhutshwa rhoqo.
Izinto Ezichaphazela Ukukhululwa Kwamayeza KwiMatrix Tablets:
Xa kuyilwa ithebhulethi ekhutshwa ixesha elide, kukho izinto ezimbini eziphambili ekufuneka ziqwalaselwe: ukwenziwa kunye nokucubungula. Kukwakho nezinto ezingaphantsi ekufuneka ziqwalaselwe xa kumiselwa ukwenziwa kunye neprofayili yokukhululwa kwemveliso yokugqibela yeyeza.
Ifomula:
Izinto ezibalulekileyo ekufuneka ziqwalaselwe xa kuphuhliswa kwangethuba:
1. I-Polymer (uhlobo lokutshintsha, i-viscosity, ubungakanani kunye nobukhulu be-particle)
2. Amayeza (ubungakanani bamasuntswana kunye nokunyibilika kwawo)
3. Izinto ezibangela ukuxinana (ukunyibilika kunye nomthamo)
4. Ezinye izinto ezincedisayo (izibambisi kunye nee-buffers)
Ubugcisa:
Ezi zinto zihambelana nendlela eveliswa ngayo eli yeza:
1. Iindlela zemveliso
2. Ubungakanani beTablet kunye neMilo
3. Amandla ethebhulethi
4. Indawo ye-pH
5. Ukwambathisa ifilimu
Indlela esebenza ngayo iitships zeskeleton:
Iipilisi ze-hydrophilic gel matrix zinokulawula ukukhutshwa kwamayeza ngokusebenzisa umaleko wejeli, kubandakanya iindlela ezimbini zokusasazwa (izithako ezisebenzayo ezinyibilikayo) kunye nokukhukuliseka (izithako ezisebenzayo ezinganyibilikiyo), ngoko ke i-viscosity ye-polymer inempembelelo enkulu kwiprofayili yokukhululwa. Besebenzisa i-hypromellose, iinkampani zamayeza zingasebenzisa itekhnoloji yethebhulethi ye-hydrophilic gel matrix ukulungisa iprofayili yokukhululwa kweyeza, zibonelela ngedosi esebenzayo ngakumbi kunye nokuthobela okungcono kwesigulane, ngaloo ndlela zinciphisa umthwalo wamayeza kwizigulana. Indlela yokuthatha amayeza kube kanye ngemini ingcono kunamava okuthatha iipilisi ezininzi izihlandlo ezininzi ngemini.
