Mokhoa oa ho qhala Hydroxypropyl Methylcellulose (HPMC): Kakaretso le Likopo


Nako ea poso: May-25-2023

Hydroxypropyl Methylcellulose (HPMC) ke polymer e feto-fetohang e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa meriana, lijo, litlolo le kaho.Mehaho ea eona e ikhethang e etsa hore e be mokhethoa ea hloahloa bakeng sa lits'ebetso tse joalo ka tokollo ea lithethefatsi e laoloang, liente tse teteaneng, ho roala lifilimi le lisebelisoa tsa kaho.Sehloohong sena, re tla shebana le mokhoa oa ho qhala oa HPMC, re lekola bohlokoa ba ona, mekhoa le ts'ebeliso ea ona.Ho utloisisa mokhoa oa ho qhala oa HPMC ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea eona le ho fihlela liphetho tse lakatsehang mafapheng a fapaneng.

Bohlokoa ba ho felisoa ha HPMC

Ho qhibiliha ha HPMC ho bolela mokhoa oa ho qhala le ho qhala polymer ka mokhoa oa mokelikeli.Mohato ona o bohlokoa kaha o lekanya sekhahla sa tokollo, bioavailability, le ts'ebetso ea lihlahisoa tse thehiloeng ho HPMC.Boitšoaro ba ho qhala ha HPMC bo ipapisitse le lintlha tse fapaneng, ho kenyeletsoa kereiti ea HPMC, boholo ba likaroloana, mocheso, pH, le mofuta oa mahareng.Ka ho ithuta mokhoa oa ho qhibiliha, bafuputsi le bahlahisi ba ka lekola ho qhibiliha, ho lokolla kinetics, le ts'ebetso e akaretsang ea libopeho tsa HPMC, tse lebisang ntlafatsong ea sehlahisoa le ntlafatso.

Mekhoa ea ho felisoa ha HPMC

Ho sebelisoa mekhoa e mengata bakeng sa ho ithuta boitšoaro ba ho qhalana ha HPMC.Mekhoa e sebelisoang haholo e kenyelletsa:

a.Apparatus I (Sesebelisoa sa Basketkete): Mokhoa ona o kenyelletsa ho beha sampole ea HPMC ka har'a seroto sa letlooeng, ebe se qoelisoa ka har'a mokelikeli oa ho qhibiliha ha se ntse se tsukutloa.Mokhoa ona o sebelisoa hangata bakeng sa liforomo tsa tokollo hang-hang mme o fana ka leseli la bohlokoa mabapi le sekhahla sa ho felisoa le boemo ba tokollo ea HPMC.

b.Apparatus II (Paddle apparatus): Ka mokhoa ona, sampuli e kenngoa ka har'a sejana sa ho qhibiliha, 'me seketsoana se sebelisetsoa ho sisinya bohareng.Mokhoa ona o loketse mefuta e 'meli ea tokollo ea hang-hang le ea tokollo e atolositsoeng, e fanang ka leseli mabapi le sekhahla sa ho felisoa le kinetics ea tokollo ea HPMC.

c.Apparatus III (Reciprocating cylinder apparatus): Mokhoa ona o kenyelletsa ho beha sampole ka har'a cylinder e khutlelang morao, e eang pele le morao mocheng oa ho qhibiliha.Mokhoa ona o atisa ho sebelisoa bakeng sa ho ithuta ka HPMC-based atolose tokollo formulations 'me o fana ka tlhahisoleseding mabapi le sekhahla sa tokollo le boitšoaro ba ho hasana ha lithethefatsi.

d.Apparatus IV (Flow-through cell apparatus): Mokhoa ona o sebelisoa haholo-holo bakeng sa ho ithuta HPMC-based transdermal patches kapa membranes.Mohlala o behiloe pakeng tsa likarolo tse peli, 'me mochine oa ho qhibiliha o lumelloa ho phalla ka har'a sampuli, ho etsisa ho lokolloa ha lithethefatsi ho pholletsa le lera.

Lisebelisoa tsa mokhoa oa ho qhala HPMC

Mokhoa oa ho qhala oa HPMC o fumana lits'ebetso tse pharalletseng liindastering tse fapaneng:

a.Indasteri ea meriana: HPMC e sebelisoa haholo e le polima ea matrix bakeng sa litlhophiso tse laoloang tsa tokollo ea lithethefatsi.Mokhoa oa ho qhala o thusa ho tseba sekhahla sa tokollo, boits'oaro ba phallo ea lithethefatsi, le mochini oa tokollo oa matlapa, li-capsules le li-pellets tse thehiloeng ho HPMC.Tlhahisoleseding ena ke ea bohlokoa bakeng sa ho ntlafatsa phano ea lithethefatsi le ho etsa bonnete ba hore ho na le liphetho tse tsitsitseng le tse lebelloang tsa kalafo.

b.Indasteri ea lijo: HPMC e sebelisoa e le ntho e tiisang le ho tsitsisa lihlahisoa tsa lijo tse kang lisoso, liaparo le lino.Mokhoa oa ho qhibiliha o thusa ho utloisisa litšobotsi tsa hydration le solubility tsa HPMC ka matrices a fapaneng a lijo, ho kenya letsoho ntlafatsong ea sebopeho, botsitso le litšobotsi tsa kutlo tsa lihlahisoa tsa ho qetela.

c.Indasteri ea litlolo: HPMC e sebelisoa ho litlolo le lihlahisoa tsa tlhokomelo ea botho e le moemeli oa ho etsa lifilimi, emulsion stabilizer, le viscosity modifier.Mokhoa oa ho qhibiliha o thusa ho lekola boleng ba ho qhibiliha le ho etsa filimi ea HPMC, ho netefatsa hore na sehlahisoa se lakatsehang, ho ata, le botsitso ba bophelo ba sethala.
