Hydroxypropyl methylcellulose (HPMC) bụ polima dị iche iche nke a na-ejikarị eme ihe n'ụlọ ọrụ ọgwụ, ọkachasị n'ụdị mbadamba. Dịka ihe sitere na cellulose, HPMC nwere ọtụtụ ihe bara uru nke na-enyere aka na arụmọrụ mbadamba n'ozuzu ya. A na-enweta ihe mejupụtara ya site na cellulose site na usoro mgbanwe kemịkalụ, na-eme ka ngwaahịa nwere ihe pụrụ iche dabara adaba maka ọtụtụ ojiji. Na usoro mbadamba, HPMC nwere ọtụtụ ojiji, gụnyere ijikwa mwepụta ọgwụ, imeziwanye njikọta mbadamba, na ime ka ọnọdụ zuru oke nke ụdị dose dịkwuo mma.
1. Ihe ndị na-ejikọ ihe na ihe ndị na-eme ka ihe dị n'ime ya sie ike:
HPMC na-arụ ọrụ dị ka ihe na-ejikọ ihe ndị dị na ya ma na-egbochi mmebi nke mbadamba tupu oge eruo. A na-ejikwa ya dị ka ihe na-eme ka mkpụrụ ndụ dị n'ime mmiri n'oge a na-emepụta ya, na-enyere aka ịmepụta mkpụrụ ndụ dị n'ime mmiri na ngwakọta ihe na-eme ka mkpụrụ ndụ dị n'ime mmiri.
2. Ihe ndị na-emepụta matrix maka mwepụta a na-achịkwa:
Otu n'ime uru dị na iji HPMC eme ihe na mbadamba bụ ikike ya ijikwa mwepụta ọgwụ. Mgbe ejiri ya dị ka matrix former, HPMC na-emepụta matrix dị ka gel mgbe ọ metụrụ mmiri aka, na-enye ohere maka ntọhapụ ọgwụ ahụ na-aga n'ihu ma na-achịkwa. Nke a dị mkpa karịsịa maka ọgwụ ndị nwere windo ọgwụgwọ dị warara ma ọ bụ ndị chọrọ ọrụ ogologo oge.
3. Ihe na-emebi ihe:
Tinyere ọrụ ya dị ka ihe na-ejikọ ọnụ, HPMC na-arụkwa ọrụ dị ka ihe na-emebi ihe na ọgwụ ndị a na-enye. Mgbe mbadamba ahụ metụrụ ihe ọṅụṅụ afọ, HPMC na-aza ma na-emebi usoro mbadamba ahụ, na-akwalite mwepụta ọgwụ ngwa ngwa. Nke a bara uru karịsịa maka ọgwụ ndị a na-ewepụta ozugbo.
4. Mkpuchi ihe nkiri:
A na-ejikarị HPMC eme ihe maka mkpuchi ihe nkiri mbadamba. HPMC na-emepụta ihe nkiri ndị na-eme ka mbadamba ahụ dị mma, na-enye nchebe megide ihe ndị metụtara gburugburu ebe obibi, a pụkwara iji ya mee ihe mkpuchi uto. Usoro mkpuchi ihe nkiri ahụ bụ itinye ngwọta HPMC n'elu mbadamba ma mepụta mkpuchi yiri nke ahụ ma doo anya mgbe ọ kpọrọ nkụ.
5. Njikwa porosity na ihe ndị na-agbanwe permeability:
Mbadamba nwere ike ịchọ njirimara porosity na permeability kpọmkwem iji nweta profaịlụ mgbaze achọrọ. Enwere ike iji HPMC gbanwee porosity na permeability nke mbadamba, na-emetụta mwepụta ọgwụ. Nke a dị oke mkpa iji nweta profaịlụ pharmacokinetic achọrọ nke ọgwụ ahụ.
6. Mmanụ Mbadamba:
HPMC na-arụ ọrụ dị ka mmanụ mbadamba, na-ebelata esemokwu dị n'etiti mbadamba na elu akụrụngwa nhazi n'oge nrụpụta. Nke a na-eme ka usoro mmepụta mbadamba dị irè ma na-eme ka mbadamba ghara ịrapara na akụrụngwa ahụ.
7. Ihe e ji emechi ihe:
N'ụfọdụ ọgwụ, ọkachasị maka nnyefe ọgwụ n'ọnụ ma ọ bụ n'ọnụ, enwere ike iji HPMC dị ka ihe na-ejikọ mucous. Ọ na-enyere aka ịgbatị oge obibi nke ụdị ọgwụ ahụ n'elu mucous, si otú a na-eme ka mmịpụta ọgwụ dịkwuo mma.
8. Ihe na-eme ka nkwụsi ike dịkwuo mma:
HPMC na-enyere aka ime ka usoro ọgwụ mbadamba dịkwuo mma site na igbochi mmiri ịmịkọrọ na ichebe ọgwụ ahụ pụọ na ihe ndị metụtara gburugburu ebe obibi. Nke a dị mkpa karịsịa maka ọgwụ ndị na-enwe mmetụta na mmiri ma ọ bụ ndị nwere ike imebi.
9. Ndakọrịta na ihe ndị ọzọ na-enye aka:
HPMC nwere ezigbo ndakọrịta na ọtụtụ ihe mgbakwunye a na-ejikarị eme ihe na mbadamba. Ndakọrịta a na-eme ka usoro dị mfe nke mbadamba nwere ọtụtụ ihe ọgwụ na ihe ndị ọzọ dị mfe.
Hydroxypropyl methylcellulose (HPMC) na-arụ ọrụ dị mkpa na usoro mbadamba, na-enye ọtụtụ ọrụ ndị na-enyere aka melite arụmọrụ na arụmọrụ nke ụdị dose ahụ. Ngwa ndị a sitere na ihe njikọta na ihe ndị na-enye granulating ruo na ihe ndị a na-achịkwa maka ntọhapụ matrix, ihe mkpuchi ihe nkiri, mmanụ na ihe ndị na-eme ka nkwụsi ike dịkwuo mma. Ọdịdị nke HPMC na-eme ka ọ bụrụ ihe bara uru na usoro ọgwụ, ojiji ya na-aga n'ihu na-egosipụta mkpa ọ dị inweta nsonaazụ nnyefe ọgwụ achọrọ.
