Aashitada hypromellose ma u adkaysataa?

Hypromellose, oo sidoo kale loo yaqaan hydroxypropyl methylcellulose (HPMC), asal ahaan uma aha mid u adkaysta aashitada. Si kastaba ha ahaatee, iska caabbinta aashitada ee hypromellose waxaa lagu xoojin karaa farsamooyin kala duwan oo qaabayn ah.

Hypromellose waa milmi karaa biyaha laakiin waa mid aan milmi karin dareerayaasha dabiiciga ah iyo dareerayaasha aan cidhifka lahayn. Sidaa darteed, deegaannada aashitada leh, sida caloosha, hypromellose wuu milmi karaa ama wuu barari karaa ilaa xad, iyadoo ku xiran arrimo ay ka mid yihiin isku-darka aashitada, pH, iyo muddada soo-gaadhista.

Si loo hagaajiyo iska caabbinta aashitada ee hypromellose ee daawooyinka, farsamooyinka dahaarka enteric-ga ayaa badanaa la adeegsadaa. Dahaarka enteric-ga waxaa lagu mariyaa kiniiniyada ama kaabsulka si looga ilaaliyo deegaanka aashitada caloosha loona oggolaado inay u gudbaan deegaanka dhexdhexaadka ah ee xiidmaha yar ka hor inta aan la sii dayn maaddooyinka firfircoon.

Dahaarka gudaha waxaa caadi ahaan laga sameeyaa polymers-ka u adkaysta aashitada caloosha, sida cellulose acetate phthalate (CAP), hydroxypropyl methylcellulose phthalate (HPMCP), ama polyvinyl acetate phthalate (PVAP). Polymers-kani waxay sameeyaan xayndaab ilaalin ah oo ku wareegsan kiniinka ama kaabsal, taasoo ka hortagaysa kala-baxa degdega ah ama burburka caloosha.

Marka la soo koobo, inkastoo hypromellose laftiisu uusan u adkaysan karin aashitada, iska caabbinta aashitada waxaa lagu xoojin karaa farsamooyinka qaabaynta sida dahaarka enteric. Farsamooyinkan waxaa badanaa loo isticmaalaa qaacidooyinka dawooyinka si loo hubiyo in si wax ku ool ah loo gaarsiiyo maaddooyinka firfircoon goobta loogu talagalay ee jirka.
