IHydroxypropyl methylcellulose (HPMC) yipolymer eguquguqukayo esetyenziswa kakhulu kwishishini loxubo mayeza, ngakumbi kuqulunqo lwethebhulethi.Njengenye yezinto eziphuma kwiselulosi, i-HPMC inoluhlu lweepropathi ezisebenzayo ezinegalelo ekusebenzeni ngokubanzi kwethebhulethi.I-compound ivela kwi-cellulose ngokusebenzisa uluhlu lweekhemikhali zokuguqulwa, okubangelwa iimveliso ezineempawu ezizodwa ezifanelekileyo kwiintlobo ezahlukeneyo zezicelo.Ekuqulunqweni kwethebhulethi, i-HPMC ineendlela ezahlukeneyo zokusetyenziswa, kubandakanywa nokulawula ukukhutshwa kweziyobisi, ukuphucula ukuhambelana kwethebhulethi, kunye nokuphucula ukuzinza ngokubanzi kwefom yedosi.
1. Izibophelelo kunye nee-arhente zegranulating:
I-HPMC isebenza njenge-binder kwi-tablet formulations, inceda ukubopha izithako kunye kunye nokuthintela ukuchithwa kwethebhulethi kwangaphambi kwexesha.Ikwasetyenziswa njenge-agent ye-granulating ngexesha lenkqubo yokuvelisa, inceda ichiza kunye nomxube we-excipient ukwenza i-granules.
2. I-agent eyenza i-matrix yokukhululwa okulawulwayo:
Enye yeenzuzo ezinkulu zokusebenzisa i-HPMC kwimixube yethebhulethi kukukwazi kwayo ukulawula ukukhutshwa kwechiza.Xa isetyenziswa njenge-matrix yangaphambili, i-HPMC yenza i-matrix efana nejeli xa idibana namanzi, ivumela ukukhutshwa okuzinzileyo nokulawulwayo kwechiza.Oku kubaluleke ngakumbi kumachiza aneefestile zonyango ezimxinwa okanye ezifuna inyathelo elide.
3. I-Disintegrant:
Ukongeza kwindima yayo njengesibophelelo, i-HPMC ikwasebenza njenge-disintegrant kuqulunqo lwethebhulethi.Xa ithebhulethi idibana nejusi yesisu, i-HPMC idumba kwaye iphazamise isakhiwo sethebhulethi, ikhuthaza ukukhutshwa kweziyobisi ngokukhawuleza.Oku kuluncedo kakhulu kwimixube yokukhululwa kwangoko.
4. Ukugquma ifilimu:
I-HPMC iqhele ukusetyenziselwa ukugquma ifilimu yethebhulethi.I-HPMC yenza iifilimu eziphucula inkangeleko yamacwecwe, zibonelela ngokhuseleko kwizinto zokusingqongileyo, kwaye zingasetyenziselwa ukufihla incasa.Inkqubo yokugquma ifilimu kukusebenzisa isisombululo se-HPMC kumphezulu wamacwecwe kwaye wenze iyunifomu kunye nokwaleka okucacileyo emva kokumisa.
5. Lawula porosity kunye nezilungisi permeability:
Iitafile zinokufuna i-porosity ethile kunye neempawu zokungena ukufikeleleka kwiprofayili efunwayo yokupheliswa.I-HPMC ingasetyenziselwa ukuguqula i-porosity kunye ne-permeability yamacwecwe, okuchaphazela ukukhutshwa kwechiza.Oku kubalulekile ukufezekisa iprofayili efunekayo ye-pharmacokinetic yechiza.
6. I-Lubricant yeTablet:
I-HPMC isebenza njenge-lubricant yethebhulethi, inciphisa ukungqubana phakathi kweetafile kunye nomgangatho wezixhobo zokusebenza ngexesha lokuvelisa.Oku kuququzelela inkqubo esebenzayo yokuvelisa ithebhulethi kwaye iqinisekisa ukuba iipilisi azinamathele kwisixhobo.
7. Izinto zokuncamathelisa:
Kwezinye iifomyula, ngakumbi kunikezelo lwechiza lwe-buccal okanye lomlomo lwe-mucosal, i-HPMC ingasetyenziswa njenge-agent ye-mucoadhesive.Inceda ukwandisa ixesha lokuhlala kwifomu yedosi kumphezulu we-mucosal, ngaloo ndlela iphucula ukufunxwa kweziyobisi.
8. Isixhasi sozinzo:
HPMC inceda ekuphuculeni uzinzo tablet formulations ngokuthintela ukufunxa ukufuma kunye nokukhusela iyeza kwizinto zokusingqongileyo.Oku kubaluleke kakhulu kumachiza anomdla wokufuma okanye othanda ukuthotywa.
9. Ukuhambelana nabanye abancedisi:
I-HPMC inokuhambelana kakuhle kunye neentlobo ezahlukeneyo ze-excipients eziqhelekileyo ezisetyenziswa kwi-tablet formulations.Oku kuhambelana kunceda ukuqulunqwa lula kweepilisi kunye neentlobo ezahlukeneyo zeziyobisi kunye nezinye izithako.
I-Hydroxypropyl methylcellulose (HPMC) idlala indima ebalulekileyo ekuqulunqweni kwethebhulethi, inika imisebenzi emininzi enceda ukuphucula ukusebenza ngokubanzi kunye nokusebenza kwefomu yedosi.Izicelo zisuka kwizibophelelo kunye nee-agent ezixutywayo ukuya kwii-matrix zokukhululwa ezilawulwayo, izixhobo zokugquma ifilimu, izithambiso kunye nezixhasi zokuzinza.Ukuguquguquka kwezinto ezininzi kwe-HPMC kuyenza ibe sisithako esixabisekileyo kuqulunqo lwamayeza, kwaye ukusetyenziswa kwayo okuqhubekayo kubonisa ukubaluleka kwayo ekuphumezeni iziphumo ezinqwenelekayo zokuhanjiswa kwechiza.
