HEC (Hydroxyethyl Cellulose)bụ polima a na-ejikarị mmiri agbaze nke a na-ejikarị eme ihe n'ọgwụ. Ọ bụ ihe sitere na cellulose, nke a na-enweta site na iji ethanolamine (ethylene oxide) na cellulose. N'ihi ezigbo mgbaze ya, nkwụsi ike ya, ikike nhazi viscosity ya na biocompatibility, HEC nwere ọtụtụ ojiji na ngalaba ọgwụ, ọkachasị na mmepe nhazi, nhazi ụdị dose na njikwa mwepụta ọgwụ nke ọgwụ.
1. Njirimara ndị bụ isi nke HEC
HEC, dị ka cellulose agbanwere agbanwe, nwere ihe ndị a bụ isi:
Mmiri na-agbaze: AnxinCel®HEC nwere ike ịmepụta mmiri na-agbaze n'ime mmiri, ọ na-agbazekwa na okpomọkụ na pH. Njirimara a na-eme ka e jiri ya mee ihe n'ọtụtụ ụdị ọgwụ dịka ọnụ na nke dị n'elu.
Ndakọrịta nke ihe ndị dị ndụ: HEC anaghị egbu egbu ma ọ naghị akpasu iwe n'ahụ mmadụ ma ọ dabara na ọtụtụ ọgwụ. Ya mere, a na-ejikarị ya eme ihe n'ụdị ọgwụ ndị na-adịgide adịgide na ụdị ọgwụ ndị e ji eme ihe n'ógbè.
Ọbara ike a na-agbanwe agbanwe: Enwere ike ịgbanwe ọbara ike nke HEC site na ịgbanwe ibu ma ọ bụ ntinye uche ya, nke dị oke mkpa maka ijikwa ọnụego mwepụta nke ọgwụ ma ọ bụ ime ka ọ kwụsie ike nke ọgwụ.
2. Itinye HEC n'ọrụ n'ọgwụgwọ
Dịka ihe dị mkpa na nkwadebe ọgwụ, HEC nwere ọtụtụ ọrụ. Ndị a bụ isi ihe e ji ya eme ihe na nkwadebe ọgwụ.
2.1 Ngwa a na-etinye n'ime ọgwụ ọnụ
N'ụdị ọgwụ a na-aṅụ n'ọnụ, a na-ejikarị HEC eme ihe n'imepụta mbadamba, kapsụl na ihe ndị ọzọ dị n'ime mmiri. Ọrụ ya bụ isi gụnyere:
Mbido: Na mbadamba na granules, enwere ike iji HEC dị ka ihe njikọta iji jikọta obere ihe ọgwụ ma ọ bụ ntụ ntụ ọnụ nke ọma iji hụ na mbadamba siri ike ma kwụsie ike.
Njikwa ntọhapụ na-adịgide adịgide: HEC nwere ike nweta mmetụta ntọhapụ na-adịgide adịgide site n'ịchịkwa ọnụego mwepụta nke ọgwụ ahụ. Mgbe ejiri HEC na ihe ndị ọzọ (dịka polyvinyl pyrrolidone, carboxymethyl cellulose, wdg.), ọ nwere ike ịgbatị oge mwepụta nke ọgwụ ahụ n'ahụ nke ọma, belata ugboro ole ọgwụ na-eme, ma melite nnabata nke onye ọrịa.
Ihe na-eme ka ọ sie ike: N'ọgwụ mmiri mmiri a na-aṅụ, AnxinCel®HEC dị ka ihe na-eme ka ọ dị arọ nwere ike ime ka ụtọ ọgwụ ahụ dịkwuo mma ma mee ka ụdị ọgwụ ahụ sie ike.
2.2 Ngwa e ji mee ihe n'ihe gbasara ọgwụgwọ
A na-ejikarị HEC eme ihe n'ude mmanụ, ude, gels, lotions na nkwadebe ndị ọzọ, na-arụ ọrụ dị iche iche:
Matrix Gel: A na-ejikarị HEC eme ihe dị ka matriks maka gels, ọkachasị na sistemụ nnyefe ọgwụ transdermal. Ọ nwere ike inye nguzozi kwesịrị ekwesị ma mee ka oge obibi ọgwụ ahụ dịkwuo elu, si otú a na-eme ka arụmọrụ ya ka mma.
Viscosity na stability: Viscosity nke HEC nwere ike ime ka nkwadebe dị n'elu akpụkpọ ahụ dịkwuo mma ma gbochie ọgwụ ahụ ịdapụ n'oge n'ihi ihe ndị dị n'èzí dịka esemokwu ma ọ bụ ịsa. Na mgbakwunye, HEC nwere ike ime ka ude na mmanụ dịkwuo mma ma gbochie nhazi ma ọ bụ kristal.
Mmanụ na ihe na-eme ka akpụkpọ ahụ dị nro: HEC nwere ezigbo ihe ndị na-eme ka akpụkpọ ahụ dị mmiri mmiri ma nwee ike inyere aka mee ka akpụkpọ ahụ dị mmiri mmiri ma gbochie nkụ, yabụ a na-ejikwa ya na ihe ndị na-eme ka akpụkpọ ahụ dị nro na ngwaahịa nlekọta akpụkpọ ahụ ndị ọzọ.
2.3 Ngwa eji eme ihe n'ime ọgwụ anya
Ojiji nke HEC na nkwadebe anya na-egosipụtakarị n'ọrụ ya dị ka ihe na-eme ka mmadụ na-arapara ma na-eme ka mmadụ nwee mmanụ:
Gel anya na mmiri anya: Enwere ike iji HEC mee ihe dị ka ihe na-arapara maka nkwadebe anya iji mee ka oge mmekọrịta dị n'etiti ọgwụ na anya dịkwuo ogologo ma hụ na ọgwụ ahụ na-arụ ọrụ nke ọma. N'otu oge ahụ, ọ na-agbawa agbawa nwekwara ike igbochi mmiri anya ịla ngwa ngwa ma mee ka oge nchekwa ọgwụ dịkwuo elu.
Mmanụ mmanụ: HEC nwere ezigbo mmiri mmiri ma nwee ike inye mmanụ mmanụ mgbe niile n'ọgwụgwọ ọrịa anya dịka anya kpọrọ nkụ, na-ebelata ahụ erughị ala anya.
2.4 Ngwa n'ime nkwadebe ọgwụ
A pụkwara iji HEC mee ihe n'ịkwadebe ụdị ọgwụ mgbochi, ọkachasị n'ọgwụ ndị na-arụ ọrụ ogologo oge na nkwadebe ndị na-adịgide adịgide. Isi ọrụ nke HEC na nkwadebe ndị a gụnyere:
Ihe na-eme ka ihe sie ike ma na-eme ka ihe sie ike: N'ime ọgwụ,HECnwere ike ime ka mmiri ọgwụ ahụ dịkwuo mma, belata ọsọ ọgwụ ahụ, ma mee ka ọgwụ ahụ kwụsie ike.
Njikwa mwepụta ọgwụ: Dịka otu n'ime ihe ndị dị na sistemụ mwepụta ọgwụ na-adịgide adịgide, HEC nwere ike ijikwa ọnụego mwepụta ọgwụ ahụ site n'ịmepụta oyi akwa gel mgbe a gbasịrị ya, iji mezuo ebumnuche nke ọgwụgwọ ogologo oge.
3. Ọrụ nke HEC na sistemụ nnyefe ọgwụ
Site na mmepe nke teknụzụ ọgwụ, ejirila HEC mee ihe nke ukwuu n'ọtụtụ usoro nnyefe ọgwụ dị iche iche, ọkachasị n'ọhịa nke ndị na-ebu ọgwụ nano, microspheres, na ndị na-ebu ọgwụ na-adịgide adịgide. Enwere ike ijikọta HEC na ọtụtụ ihe ndị na-ebu ọgwụ iji mepụta ihe siri ike iji hụ na a na-ewepụta ya mgbe niile ma na-enye ya nke ọma.
Onye na-ebu ọgwụ nano: Enwere ike iji HEC mee ihe dị ka ihe na-eme ka ihe nano sie ike iji gbochie mkpokọta ma ọ bụ mmiri ozuzo nke ihe ndị na-ebu ya ma mee ka ọgwụ ndị dị ndụ dịkwuo mma.
Microspheres na ihe ndị dị n'ime ya: Enwere ike iji HEC kwadebe microspheres na microparticle drugs iji hụ na ọgwụ ndị ahụ na-apụta nwayọ nwayọ ma melite arụmọrụ nke ọgwụ.
Dịka ihe na-enye ọgwụ dị iche iche ma na-arụ ọrụ nke ọma, AnxinCel®HEC nwere ohere sara mbara maka ojiji na nkwadebe ọgwụ. Site na mmepe na-aga n'ihu nke teknụzụ ọgwụ, HEC na-arụ ọrụ dị mkpa na njikwa mwepụta ọgwụ, nchịkwa mpaghara, nkwadebe mwepụta na-adịgide adịgide na sistemụ nnyefe ọgwụ ọhụrụ. Nkwekọ bio ya dị mma, viscosity na nkwụsi ike a na-agbanwe agbanwe na-eme ka ọ ghara ịnọchi anya n'ọhịa ọgwụ. N'ọdịnihu, site na ọmụmụ miri emi nke HEC, ojiji ya na nkwadebe ọgwụ ga-adịkwu ukwuu ma dị iche iche.
