I-Hypromellose yi-hydrophilic, i-polymer engeyona i-ionic esetyenziswa kwiintlobo ngeentlobo zamachiza kunye nezicelo zonyango, kubandakanywa njenge-lubricant kunye ne-viscosity agent kwi-drops yamehlo, njenge-agent yokugquma kwiipilisi kunye ne-capsules, kunye ne-arhente yokukhululwa okuqhubekayo kwiyeza. iinkqubo zonikezelo. Indlela yokusebenza ye-hypromellose inxulumene neempawu zayo ezizodwa ze-physicochemical, kubandakanywa amandla ayo aphezulu okubamba amanzi kunye nokukwazi ukwenza iigels phambi kwamanzi.
- Ukuthambisa: Kwimeko ye-hypromellose eyehlayo, eyona ndlela iphambili yokwenza i-lubrication. Xa isetyenziswe kumphezulu weliso, i-hypromellose yenza ifilimu encinci enceda ukunciphisa ukungqubuzana phakathi kwejwabu leso kunye ne-cornea, ngaloo ndlela inciphisa ukoma, ubomvu, kunye nokucaphuka. Lo mphumo wokuthambisa ubangelwa kumandla aphezulu okugcina amanzi e-hypromellose, evumela ukuba ithathe kwaye igcine umswakama kwifilimu yokukrazula, kunye nokukwazi kwayo ukusasazeka ngokulinganayo phezu kweso.
- I-Viscosity: I-Hypromellose inokunyusa i-viscosity yezisombululo, ezinokuthi ziphucule ukugcinwa kwazo kwi-ocular surface kunye nokwandisa ixesha lokuqhagamshelana neso. Esi siphumo sibaluleke kakhulu kwimeko yokuhla kwamehlo, njengoko kunokunceda ukwandisa ukusebenza konyango lweyeza.
- Ukugqoka: I-Hypromellose isetyenziswa ngokuqhelekileyo njenge-ejenti yokugqoka kwiipilisi kunye neepilisi. Kwesi sicelo, yenza umaleko okhuselayo ojikeleze iyeza elinokunceda ukulawula izinga lokukhutshwa kwechiza kunye nokukhusela ichiza ekuthotyweni esiswini okanye emathunjini. Indlela yokusebenza ye-hypromellose kulo mongo inxulumene nokukwazi kwayo ukwenza umqobo phakathi kwechiza kunye nendawo engqongileyo, enokunceda ukuphucula ukuzinza kunye ne-bioavailability yeyeza.
- Ukukhutshwa okuZinzileyo: I-Hypromellose inokusetyenziswa njenge-ejenti yokukhululwa okuqhubekayo kwiinkqubo zokuhanjiswa kweziyobisi. Kwesi sicelo, sisetyenziselwa ukwenza i-gel-efana ne-matrix enokulawula ukukhutshwa kweyeza kwithuba elide lexesha. Indlela yokusebenza ye-hypromellose kulo mongo inxulumene nokukwazi kwayo ukwenza inethiwekhi yeebhondi ze-hydrogen ezinokubamba iimolekyuli zeziyobisi kunye nokulawula ukukhululwa kwazo.
Indlela yokusebenza ye-hypromellose ihambelana neempawu zayo ezikhethekileyo ze-physicochemical, ezibandakanya amandla aphezulu okubamba amanzi, ukukwazi ukwenza iigels phambi kwamanzi, kunye nokukwazi ukunyusa i-viscosity yezisombululo. Ezi zakhiwo zenza ukuba i-polymer eguquguqukayo kwaye isetyenziswe ngokubanzi kumashishini amayeza kunye nezonyango, ngokukodwa ekuphuhliseni amaconsi amehlo, iipilisi, iipilisi, kunye neenkqubo zokuhanjiswa kweziyobisi.
