IHydroxypropyl Methyl Cellulose (HPMC), eyaziwa nangokuthi i-hypromellose, isetshenziswa ngokuyinhloko njengesithako esingasebenzi ekwenziweni kwemithi ehlukahlukene esikhundleni sokwelashwa okuqondile kwezimo zezokwelapha.Isebenza njenge-excipient yezemithi, inikela kuzo zonke izakhiwo nokusebenza kwemithi.Izimo ezithile zezokwelapha eziphathwa ngezidakamizwa eziqukethe i-hypromellose zincike ezingxenyeni ezisebenzayo kulawo mafomu.

Njenge-excipient, i-HPMC ivamise ukusetshenziswa kwezemithi ngezinjongo ezilandelayo:

1. Izibophezelo Zethebhulethi:
   • I-HPMC isetshenziswa njengesihlanganisi ekwakhiweni kwethebhulethi, esiza ukubamba izithako ezisebenzayo ndawonye nokudala ithebhulethi ehlangene.
2. I-ejenti yokuhlanganisa ifilimu:
   • I-HPMC iqashwe njenge-ejenti yokuhlanganisa ifilimu yamaphilisi namaphilisi, ihlinzeka ngokunamathela okubushelelezi, okuvikelayo okwenza kube lula ukugwinya nokuvikela izithako ezisebenzayo.
3. Amafomula Okukhishwa Okuqhubekayo:
   • I-HPMC isetshenziswa ekwakhiweni kokukhishwa okuqhubekayo ukulawula ukukhishwa kwezithako ezisebenzayo esikhathini esinwetshiwe, iqinisekisa umphumela wokwelapha omude.
4. I-Disintegrant:
   • Kwezinye izimo, i-HPMC isebenza njenge-disntegrant, esiza ekwahlukaniseni amaphilisi noma amaphilisi ohlelweni lokugaya ukudla ukuze kukhishwe izidakamizwa ngempumelelo.
5. Izixazululo ze-Ophthalmic:
   • Kuzixazululo ze-ophthalmic, i-HPMC ingaba negalelo ku-viscosity, inikeze ukwakheka okuzinzile okunamathela endaweni ye-ocular.

Kubalulekile ukuqaphela ukuthi i-HPMC ngokwayo azilaphi izimo ezithile zezokwelapha.Kunalokho, idlala indima ebalulekile ekwakhiweni nasekulethweni kwemithi.Izithako ezisebenzayo zemithi (ama-API) emthini zinquma umphumela wokwelapha kanye nezimo zezokwelapha ezihlosiwe.

Uma unemibuzo mayelana nemithi ethile equkethe i-hypromellose noma uma ufuna ukwelashwa ngenxa yesimo sezempilo, kubalulekile ukubonana nochwepheshe bezokunakekelwa kwempilo.Banganikeza ulwazi mayelana nezithako ezisebenzayo emithini futhi bancome ukwelashwa okufanele okusekelwe ezidingweni zakho zezempilo ezithile.
