Ngaba i-hypromellose acid ayimelani nayo?

I-Hypromellose, ekwaziwa ngokuba yi-hydroxypropyl methylcellulose (HPMC), ayimelani ne-asidi ngokwemvelo. Nangona kunjalo, ukumelana ne-asidi ye-hypromellose kunokwandiswa ngeendlela ezahlukeneyo zokwenza.

I-Hypromellose iyanyibilika emanzini kodwa ayinyibiliki kakhulu kwizinyibilikisi zendalo kunye nolwelo olungelulo lwe-polar. Ke ngoko, kwiindawo ezine-asidi, njengesisu, i-hypromellose inokunyibilika okanye idumbe ukuya kuthi ga kwinqanaba elithile, kuxhomekeke kwizinto ezifana noxinzelelo lwe-asidi, i-pH, kunye nobude bexesha lokuvezwa.

Ukuphucula ukumelana ne-asidi ye-hypromellose kwiifomyula zamayeza, iindlela zokugquma i-enteric zihlala zisetyenziswa. Ii-enteric coating zisetyenziswa kwiipilisi okanye kwiikhaphu ukuze zikhuseleke kwindawo ene-asidi esiswini kwaye zivumele ukuba zidlule kwindawo engenamkhethe yamathumbu amancinci ngaphambi kokuba zikhuphe izithako ezisebenzayo.

Iingubo ze-enteric zihlala zenziwe ngee-polymers ezimelana ne-asidi yesisu, ezifana ne-cellulose acetate phthalate (CAP), i-hydroxypropyl methylcellulose phthalate (HPMCP), okanye i-polyvinyl acetate phthalate (PVAP). Ezi polymers zenza umqobo okhuselayo ojikeleze ithebhulethi okanye i-capsule, zithintela ukunyibilika kwangaphambi kwexesha okanye ukubola esiswini.

Ngamafutshane, nangona i-hypromellose ngokwayo ingamelani ne-asidi, ukumelana kwayo ne-asidi kunokwandiswa ngeendlela zokwenza izinto ezifana nokufaka i-enteric coating. Ezi ndlela zihlala zisetyenziswa kwiifomyula zamayeza ukuqinisekisa ukuhanjiswa ngempumelelo kwezithako ezisebenzayo kwindawo ecetywayo yokusebenza emzimbeni.
