Tsepamisa maikutlo ho Cellulose ethers

Tšebeliso ea marotholi a HPMC ke eng?

Hydroxypropyl Methylcellulose (HPMC) ke semi-synthetic polymer e sebelisoang hangata e nang le biocompatibility e ntle, e se nang chefo le viscosity e phahameng. Lefapheng la meriana, HPMC e sebelisoa haholo ka mefuta e fapaneng ea litekanyetso, tseo har'a tsona marotholi e leng e 'ngoe ea litšebeliso tsa eona tsa bohlokoa. Marotholi a HPMC a bua haholo ka litokisetso tsa mokelikeli tse lokiselitsoeng ka HPMC e le eona ntho e ka sehloohong ea ho etsa lifilimi kapa motenya. E na le ho khomarela hantle, ho lokolloa ho tsitsitseng le botsitso, 'me e loketse meriana ea lihlooho likarolong tse sa tšoaneng tse kang ophthalmology, otology, nasal cavity le molomo oa molomo.

Hydroxypropyl Methylcellulose (HPMC)

1. Litšobotsi tsa motheo tsa marotholi a HPMC

HPMC ke non-ionic cellulose ether e nang le melemo e latelang:

Matla a matla le ho khomarela: ho thusa ho eketsa nako ea bolulo ea lithethefatsi holim'a lisele tsa sebaka seo.

Biocompatibility e ntle: e sa halefeng, ha e bake ho itšoara hantle, 'me e loketse libaka tse nang le bothata bo kang mahlo.

Pontšo e hlakileng le e se nang 'mala, botsitso ba pH bo botle: e loketse ho sebelisoa e le sejana sa marotholi, ha e ame pono le mesebetsi ea 'mele.

Tokollo e tsitsitseng: e ka laola sekhahla sa ho lokolloa ha lithethefatsi le ho lelefatsa ts'ebetso.

Litšobotsi tsena li etsa hore HPMC e be mothusi ea loketseng litokisetsong tsa marotholi, haholo maemong ao ho ona ho hlokahalang tokollo e tsitsitseng kapa ho tlotsoa.

 

2. Tšebeliso ea mantlha ea marotholi a HPMC

2.1. Meokho ea maiketsetso/litlolo tsa mahlo

Ena ke e 'ngoe ea maemo a atileng haholo a ts'ebeliso ea marotholi a HPMC. Meokho ea maiketsetso e sebelisoa haholo-holo ho imolla mahlo a omileng, mokhathala oa mahlo, ho se phutholohe ho bakoang ke ho roala lense ea nako e telele, le mathata a mang. HPMC e bapala karolo e latelang ea mantlha ho marotholi a mahlo:

Ho etsisa meokho ea tlhaho: HPMC e na le pokello e ntle ea metsi le lubricity, e ka etsisa ts'ebetso ea meokho ea tlhaho, 'me ea imolla mahlo a omileng.

Ho eketsa nako ea ho khomarela lithethefatsi: Ka ho etsa filimi e tšesaane, nako ea ho boloka lithethefatsi sebakeng sa mahlo e ntlafatsoa, ​​'me katleho ea ntlafatsoa.

Ho thusa metsoako e meng: Hangata e sebelisoa le mafura a kang PVA (polyvinyl alcohol) le PEG (polyethylene glycol) ho matlafatsa maikutlo a tšebeliso.

Lihlahisoa tse tloaelehileng tse kang "hydroxypropyl methylcellulose eye drops" le "Runjie artificial tears" kaofela li na le metsoako ea HPMC.

 

2.2. Thickener bakeng sa marotholi a mahlo a ophthalmic therapeutic

HPMC e ke ke ea sebelisoa feela joalo ka setlolo, empa e boetse e sebelisoa hangata ho marotholi a mahlo a kalafo, joalo ka lithethefatsi tse khahlanong le ho ruruha, lithibela-mafu, lithethefatsi tsa glaucoma, joalo-joalo, ho:

Ntlafatsa botsitso ba lithethefatsi;

Fokotsa ho tlosoa ha lithethefatsi;

Fokotsa makhetlo a ho noa le ho ntlafatsa ho latela melao ea mokuli.

Ka mohlala, ka linako tse ling HPMC e eketsoa ho marotholi a mahlo a levofloxacin a sebelisoang ho phekola conjunctivitis ho lelefatsa nako ea ts'ebetso ea lithethefatsi ka mokotleng oa conjunctival.

 

2.3. Otolaryngology e theoha

Marotholing a nko le litsebeng, HPMC e atisa ho sebelisoa e le matrix e teteaneng kapa e sa khaotseng bakeng sa maemo a latelang:

Auricular anti-infective drops: HPMC e thusa sethethefatsi hore se lule se le kanaleng ea tsebe le ho ntlafatsa phello ea bactericidal ea sebakeng seo.

Marotholi a Ninitis: Thepa e tsitsitseng ea tokollo e lumella lithethefatsi tse khahlanong le ho ruruha kapa tse khahlanong le ho kula hore li be le phello e tšoarellang le ho fokotsa tahlehelo ea lithethefatsi e bakoang ke ho phalla ha nko.

 

2.4. Marotholi a molomo oa mucosal

Ha ho phekoloa liso tsa molomo kapa li-mucositis, lithethefatsi tse ling li etsoa marotholi e le hore li ka theoleloa ka ho toba sebakeng sa leqeba. HPMC e ka fana ka ho khomarela le tokollo e tsitsitseng, e lumellang moriana hore o sebetse hantle sebakeng se amehileng.

 

3. Melemo ea moralo oa foromo ea litekanyetso tsa marotholi a HPMC

HPMC ha se feela setenya ka har'a foromo ea lerotholi, empa hape ke sesebelisoa sa bohlokoa se sebetsang. Melemo ea eona e bonahala ho:

Tšireletseho e phahameng: ha e amoheloe ke 'mele oa motho, ha ho chefo ea tsamaiso, e loketseng tšebeliso ea nako e telele.

Ntlafatsa phihlelo ea mokuli: ha ho na ho teneha, ho phutholoha ho sebelisoa, haholo-holo ho loketse bakuli ba nang le kutloelo-bohloko ba kang masea le batho ba hōlileng.

Khokahano e ntle: e ka phela hammoho le mefuta e fapaneng ea metsoako e sebetsang, ha ho bonolo ho baka litlamorao tse mpe.

Ho bonolo ho e lokisa le ho e boloka: Marotholi a HPMC a na le botsitso bo botle le pepeneneng mocheso oa kamore 'me a bonolo ho etsa indasteri.

Melemo ea moralo oa foromo ea litekanyetso tsa marotholi a HPMC
