HPMC EXCIPIENT

Ha ho etsoa meriana, Hydroxypropyl Methylcellulose (HPMC) e atisa ho sebelisoa e le motsoako, e leng motsoako o sa sebetseng o kentsoeng motsoako oa lithethefatsi bakeng sa merero e fapaneng. Mona ke kamoo HPMC e sebetsang ka teng e le mothusi ho tsa meriana:

  1. Binder: HPMC e sebetsa e le tlamahano mefuteng ea matlapa, e thusang ho kopanya metsoako e sebetsang ea meriana (APIs) le lisebelisoa tse ling hammoho ho etsa matlapa. E ntlafatsa momahano oa letlapa mme e fana ka matla a mochini, e thusa ts'ebetsong ea khatello nakong ea tlhahiso ea matlapa.
  2. Disintegrant: HPMC e ka boela ea sebetsa e le ntho e senyang, e thusang ho aroloa ha matlapa kapa li-capsules hore e be likaroloana tse nyenyane ha li kopana le maro a metsi (joaloka lero la gastric ka har'a pampiri ea mala). Sena se khothalletsa ho qhibiliha le ho monya ha lithethefatsi, ho matlafatsa bioavailability.
  3. Filimi ea Pele: HPMC e sebelisoa e le moemeli oa ho etsa lifilimi tlhahiso ea liforomo tsa litekanyetso tse tiileng tsa molomo joalo ka matlapa le li-pellets. E etsa seaparo se tšesaane, se ts'oanang sa filimi holim'a matlapa kapa li-pellets, ho fana ka tšireletso khahlanong le mongobo, khanya le ho senyeha ha lik'hemik'hale. Liaparo tsa filimi li ka boela tsa pata tatso le monko oa lithethefatsi le ho ntlafatsa ho metsa.
  4. Viscosity Modifier: Ka mefuta ea litekanyetso tsa mokelikeli joalo ka ho emisoa, li-emulsion, le marotholi a mahlo, HPMC e sebetsa joalo ka mofetoleli oa viscosity. E eketsa viscosity ea sebopeho, ho ntlafatsa botsitso ba eona, thepa ea rheological, le boiketlo ba tsamaiso. Viscosity e laoloang e boetse e thusa kabong e tšoanang ea likaroloana tsa API.
  5. Stabilizer: HPMC e ka sebetsa e le stabilizer ka emulsions le suspensions, ho thibela karohano ea mekhahlelo le sedimentation ea likaroloana tse qhalakaneng. E matlafatsa botsitso ba 'mele ea ho etsoa, ​​​​ho lelefatsa bophelo ba sethala le ho netefatsa ho tšoana ha phano ea lithethefatsi.
  6. Sustained Release Agent: HPMC e sebelisoa ha ho etsoa liforomo tsa tokollo e laoloang kapa ea tokollo e atolositsoeng. E ka laola sekhahla sa ho lokolloa ha lithethefatsi ka ho theha matrix ea gel kapa ho thibela ho ata ha lithethefatsi ka matrix a polymer. Sena se lumella ho lokolloa ha lithethefatsi ka nako e telele le ho laoloa ka nako e telele, ho fokotsa makhetlo a mangata le ho ntlafatsa ho latela melao ea mokuli.

Ka kakaretso, HPMC e sebetsa e le mothusi ea ka feto-fetohang mekhoeng ea meriana, e fana ka lits'ebetso tse fapaneng tse kang ho tlama, ho arohana, ho etsa lifilimi, phetoho ea viscosity, botsitso le tokollo e tsitsitseng. Biocompatibility ea eona, polokeho, le kamohelo ea taolo li e etsa hore e sebelisoe haholo indastering ea meriana.
