Hypromellose acid miyuu u adkaystaa?

Hypromellose, oo sidoo kale loo yaqaan hydroxypropyl methylcellulose (HPMC), ma aha mid si dabiici ah u adkaysta. Si kastaba ha ahaatee, caabbinta aashitada ee hypromellose ayaa lagu wanaajin karaa iyada oo loo marayo farsamooyin diyaarin oo kala duwan.

Hypromellose waxay ku milmi kartaa biyaha laakiin waa mid aan lagu milmi karin dareerayaasha organic iyo dareeraha aan polarka ahayn. Sidaa darteed, meelaha acidic ah, sida caloosha, hypromellose ayaa laga yaabaa inay milmaan ama bararto ilaa xad, taas oo ku xidhan arrimo ay ka mid yihiin xoojinta acid, pH, iyo muddada soo-gaadhista.

Si loo wanaajiyo iska caabbinta aashitada ee hypromellose ee qaababka dawooyinka, farsamooyinka dahaarka gudaha ayaa inta badan la adeegsadaa. Dahaarka enteric ayaa lagu dabaqaa kaniiniyada ama kaabsal si looga ilaaliyo deegaanka acidic ee caloosha oo u oggolaadaan inay u gudbaan jawiga dhexdhexaadka ah ee xiidmaha yar ka hor inta aan la sii dayn maaddooyinka firfircoon.

Dahaarka gudaha waxaa sida caadiga ah laga sameeyaa polymers u adkaysta acid gastric, sida cellulose acetate phthalate (CAP), hydroxypropyl methylcellulose phthalate (HPMCP), ama polyvinyl acetate phthalate (PVAP). Polymers-yadani waxay sameeyaan xannibaad ka hortag ah oo ku wareegsan kiniinka ama kaabsoolka, ka hortagga burburka degdegga ah ama hoos u dhaca caloosha.

Marka la soo koobo, halka hypromellose lafteedu aysan u adkaysan karin aashitada, iska caabbinta aashitada waxaa lagu wanaajin karaa farsamooyinka qaabaynta sida dahaarka gudaha. Farsamooyinkan waxaa sida caadiga ah loo isticmaalaa hababka dawooyinka si loo hubiyo bixinta waxtarka leh ee maaddooyinka firfircoon ee goobta loogu talagalay ficilka jirka.
