12. Ọnụ-arụ ọrụ
HPC dị ọnụ ahịa dị oke ọnụ ma e jiri ya tụnyere ụfọdụ polymers pụrụ iche, na-enye nguzozi n'etiti arụmọrụ na ikike.Ngwa ngwa ya sara mbara nwere ike ibelata mkpa maka ọtụtụ ihe mgbakwunye, na-eme ka mmepe na imepụta ihe dị mfe.
Ọmụmụ ihe na ngwa
Ọtụtụ ọmụmụ ihe na-egosi ịdị irè nke HPC n'ụdị dị iche iche:
Mbadamba mwepu na-adịgide adịgide: ejirila HPC mee ihe nke ọma n'ụdị mbadamba ihe ntọhapụ metformin hydrochloride, na-enye ntọhapụ ọgwụ na-agbanwe agbanwe karịa awa 12-24.
Nkwalite Solubility: Ọgwụ dị ka itraconazole egosila mma solubility na bioavailability mgbe ejiri HPC mee ya na mgbasa ozi siri ike.
Ihe mkpuchi ihe nkiri: N'ime mbadamba ihe mkpuchi nke enteric, a na-eji mkpuchi mkpuchi HPC mee ihe iji gbuo oge ịhapụ ọgwụ ruo mgbe mbadamba ahụ rutere eriri afọ, na-echebe ọgwụ ahụ site na gastric acid.
Hydroxypropyl cellulose na-enye ọtụtụ uru dị ka ihe excipient n'ụdị usoro onunu ogwu siri ike.Ọrụ ya dị ka ihe nkwekọ, ihe nkiri mbụ, matriks ntọhapụ a na-achịkwa, yana ihe nkwalite solubility, n'etiti ndị ọzọ, na-egosipụta ike ya na uru ya na usoro ọgwụ.HPC na-akwalite akụrụngwa akụrụngwa, nkwụsi ike na bioavailability nke ọgwụ, ma na-enye mgbanwe n'ichepụta usoro nnyefe ọgwụ dị iche iche.Ọ dị mfe iji ya eme ihe, ihe ndị dị ndụ, na ọnụ ahịa bara uru na-eme ka ọ bụrụ akụkụ bara uru na mmepe ọgwụ ọgbara ọhụrụ.
