Hypromellose e sebelisitsoeng litafoleng?

Hypromellose, e boetse e tsejoang e le hydroxypropyL methylcellllll (HPMC), e sebelisoa hangata ka liphetola tsa mabitla bakeng sa 'maloa:

1. Tlatsetso: HPMC hangata e sebelisoa e le mokhoa oa ho etsa metsoako ea matala ho tšoara metsoako e sebetsang ea meriana (APIS) le batho ba bang hammoho. Joaloka 'matla, HPMC e thusa ho theha matlakala a kopaneng a nang le matla a kopaneng a nang le matla a lekaneng a nang le matla a lekaneng, a netefatsa hore matlapa a boloka botšepehi ba ona nakong ea ho sebetsana le ho boloka thepa le ho boloka.
2. Ho se sebetse hantle: Ntle le thepa ea eona e tlamang, HPMC e ka sebetsa e le moferefere litafoleng. Ho senyeha thuso ho khothaletsa karohano e potlakileng kapa ho senya letlapa ha ho kenella meroho, ho toba ho lokolloa ha liphithethefatsi le ho monya koluoa ​​ea liphio. HPMC e kenella kapele le metsi, e lebisang karolong ea letlapa ho fihlela likarolong tse nyane le ho thusa ho khesoa ha mafube.
3. Movie eohle / Coating Agent: HPMC e ka sebelisoa e le thepa e etsang lifoto kapa litafole tsa litafole. Ha HPM e sebelisoa e le filimi e tšesaane holim 'a letlapa, HPMC e thusa ho ntlafatsa ponahalo, ho metsi le botsitso ba letlapa. E ka boela ea rehlatisa ho sireletsa letlapa, bobebe le likhase tse se nang sepakapaka, ka tsela e nyonyehang li khabisa bophelo ba sehatse le ho boloka poteishene ea lithethefatsi.
4. Matrix Ead: Ka mekhoa ea theko e laoloang kapa ea PPMC hangata e sebelisoa e le moetsi oa mantlha. Joaloka moemeli oa pele, HPM Sena se lumella ho tsamaisoa ka lithethefatsi tse laoloang le ho ntlafatsa mokuli ka ho fokotsa khafetsa ea dosing.
5. Toka: HPMC e kanna ea sebelisoa e le ea hlokolosi litabeng tsa tafole ho fetola thepa ea letaba, e joalo ka thata, ho senyeha le sekhahla sa disphop. Thepa ea eona e fapaneng e etsa hore e be e loketseng ho sebelisoa ka mekhahlelo e fapaneng, ho kenyelletsa le tokollo e potlakileng, e liehang - lokollotsoe le matlapa a tokoselitsoeng.

Ka kakaretso, HPMC e sebelisoa haholo meriana e sebelisoang haholo meriana ka lebaka la ho se sebetse hantle ha eona, ho sitisoha le katleho ho fihlella matla a matla a matla a ho fumana thepa ea matla. Tight ea eona ea mafili e lumella litsebi ho latela litlhoko tsa lefeela ho fihlela litlhoko tse ikhethang tsa lithethefatsi le litlhoko tsa mokuli.
