Hydroxypropyl methylcellulose bụ ihe dị ịrịba ama nonionic agwakọta ether nke cellulose nke gbanweela ụlọ ọrụ kemịkalụ.A na-emepụta polymer site n'ịgbanwe cellulose eke sitere na osisi ma ọ bụ owu.A na-eji HPMC eme ihe n'ụzọ dị iche iche n'ihi ihe ndị magburu onwe ya gụnyere ịgba, nkwụsịtụ, emulsifying, mmanụ mmanu na njide mmiri.
Na mgbakwunye, HPMC nwere njikwa mara mma na mwepụta nke ihe ndị na-arụ ọrụ na usoro ọgwụ dị iche iche, gụnyere mbadamba, capsules, ointments, na gels.Site na ịdị ọcha ya dị elu yana ezigbo bioacompatibility, HPMC na-ezute ụkpụrụ ọgwụ kachasị elu, na-emeziwanye ogo na nrụpụta ọgwụ.

Arụ ọrụ kacha mma nke HPMC sitere na ntinye nke hydroxypropyl na otu methyl na ọkpụkpụ cellulose.Ndị otu Hydroxypropyl (HP) na-ahụ maka ịba ụba solubility, ebe otu methyl na-ebelata njikọkọ hydrogen ma kwalite solubility mmiri.Ogo nke nnọchi nke otu HP na methyl na HPMC dị oke mkpa n'ịchọpụta akụrụngwa ya, gụnyere viscosity na solubility.
HPMC bụ akụkụ dị mkpa nke sistemụ nnyefe ọgwụ na-achịkwa.N'ime usoro ndị a, HPMC na-ebuli ntọhapụ ọgwụ n'ụzọ a na-achịkwa, na-ahụ na ọ dị mma ọgwụgwọ ọgwụgwọ, ịba ụba bioavailability na mbelata mmetụta.A pụkwara ịmepụta polymer n'ime mbadamba ihe matriks, nke nwere ihe ndị na-ahapụ ya, na-ekwe ka a na-ahapụ ọgwụ ahụ n'ime ahụ ruo ogologo oge.
