Zisetyenziselwa ntoni i-HPMC kunye ne-PEG?

I-Hydroxypropyl methylcellulose (HPMC) kunye ne-polyethylene glycol (PEG) zizinto ezimbini ezisetyenziswa ngeendlela ezahlukeneyo kumashishini ahlukeneyo.

IHydroxypropyl Methylcellulose (HPMC):

Amayeza: I-HPMC isetyenziswa kakhulu kwimixube yamayeza njenge-thickener, binder, film former, kunye ne-sustained-release agent kwi-tablet coatings kunye ne-controlled-release matrices.

Ukuhanjiswa Kwamayeza Omlomo: Isebenza njengotshintsho lwe-viscosity kwiifom zedosi yolwelo efana nesiraphu, ii-suspensions, kunye nee-emulsions, iphucula uzinzo kunye nokuthandeka kwazo.

Iifomyula zamehlo: Kwii-eye drops nakwizisombululo zamehlo, i-HPMC isebenza njenge-lubricant kunye ne-viscosity-enhancing agent, yandisa ixesha lokudibana kwesiyobisi nomphezulu wamehlo.

Ukulungiswa Kwezinto Ezisemzimbeni: I-HPMC isetyenziswa kwiikhrimu, iijeli, kunye neeointments njenge-arhente yokwenza lukhuni, inika ukuhambelana okufunekayo kwaye iphucula ukusasazeka kwefomyula.

Iimpahla zokugquma amanxeba: Isetyenziswa kwiimpahla zokugquma amanxeba ezisekelwe kwi-hydrogel ngenxa yeempawu zayo zokugcina umswakama, inceda ukuphiliswa kwamanxeba kwaye ikhuthaza indawo emanzi yamanxeba.

Ishishini Lokwakha: I-HPMC yongezwa kwiimortars ezisekwe kwisamente, iiplasta, kunye nezincamathelisi zethayile ukuphucula ukusebenza kakuhle, ukugcinwa kwamanzi, kunye neempawu zokunamathela.

Ishishini Lokutya: Kwimveliso yokutya, i-HPMC isebenza njengesithambisi-zinzisi, isiqinisi, kunye nesinyibilikisi, iphucula ubume, ixesha lokuphelelwa, kunye nokuziva komlomo. Ixhaphake kakhulu kwiimveliso zebhaka, ezinye iindlela zobisi, iisosi, kunye needressing.

Iimveliso zoKhathalelo loMntu: I-HPMC ifakwe kwizinto zokuthambisa kunye nezinto zokhathalelo lobuqu ezifana neeloshini, iikhrimu, kunye neemveliso zokhathalelo lweenwele njenge-arhente yokuqina nokuxhoma, okuphucula ukuhambelana kwemveliso kunye nozinzo.

Iipeyinti kunye neengubo: I-HPMC isetyenziswa kwiipeyinti kunye neengubo ezisekelwe emanzini ukulawula ukuxinana, ukuthintela ukugoba, kunye nokuphucula ukunamathela kwiziseko.

I-Polyethylene Glycol (i-PEG):

Amayeza: I-PEG isetyenziswa kakhulu kwimixube yamayeza njenge-arhente yokunyibilikisa, ingakumbi kumayeza anganyibilikiyo emanzini kakuhle, kwaye njengesiseko seenkqubo ezahlukeneyo zokuhambisa amayeza ezifana nee-liposomes kunye nee-microspheres.

Iilaxatives: Iilaxatives ezisekelwe kwi-PEG zisetyenziswa kakhulu kunyango lokuqhinwa ngenxa yesenzo sazo se-osmotic, zitsala amanzi emathunjini kwaye zithambise isitulo.

Izinto zokuthambisa: I-PEG isetyenziswa kwiindlela zokuthambisa ezifana neekhrimu, iiloshini, kunye neeshampu njenge-emulsifier, i-humectant, kunye ne-solvent, nto leyo ephucula uzinzo kunye nokuthungwa kwemveliso.

Ii-Lubricants zobuqu: Ii-lubricants ezisekelwe kwi-PEG zisetyenziswa kwiimveliso zokhathalelo lomntu kunye nee-lubricants zesondo ngenxa yokuba zithambile, azinamatheli kwaye zinyibilika ngamanzi.

I-Polymer Chemistry: I-PEG isetyenziswa njengomanduleli ekuhlanganisweni kwee-polymers ezahlukeneyo kunye nee-copolymers, ezinegalelo kwisakhiwo kunye neempawu zazo.

Iimpendulo zeekhemikhali: I-PEG isebenza njengesixhobo sokusabela okanye isinyibilikisi kwi-organic synthesis kunye neempendulo zeekhemikhali, ngakumbi kwiimpendulo ezibandakanya iikhompawundi ezibuthathaka emanzini.

Ishishini leempahla zelaphu: I-PEG isetyenziswa ekucubungulweni kweempahla zelaphu njenge-lubricant kunye ne-finishing agent, iphucula indlela elivakala ngayo ilaphu, ukuqina kwalo, kunye neempawu zokudaya.

Ishishini Lokutya: I-PEG isetyenziswa njengesithambisi-moya, isiqinisi, kunye nesiqinisi kwiimveliso zokutya ezifana neempahla ezibhakiweyo, iilekese, kunye nezinto zobisi, nto leyo ephucula ukuthungwa kunye nexesha lokuphelelwa.

Izicelo zeBiomedical: I-PEGylation, inkqubo yokuncamathisela ii-PEG chains kwi-biomolecules, isetyenziselwa ukuguqula i-pharmacokinetics kunye ne-biodistribution yeeproteni zonyango kunye ne-nanoparticles, ukwandisa ixesha lokujikeleza kwazo kunye nokunciphisa i-immunogenicity.

I-HPMC kunye ne-PEG zifumana usetyenziso oluxhaphakileyo kumashishini athengisa amayeza, ukutya, izinto zokuthambisa, ulwakhiwo, kunye namanye amashishini ahlukeneyo, ngenxa yeempawu zazo eziguquguqukayo kunye nemisebenzi yazo.
