Lekwasị anya na cellulose ethers

Gịnị bụ kpọmkwem ngwa nke cellulose ethers na ụlọ ọrụ ọgwụ?

Nkwadebe ntọhapụ na-achịkwa: Cellulose ethers dị ka HPMC (hydroxypropyl methylcellulose) na-ejikarị dị ka ihe ọkpụkpụ hydrogel na nkwado nkwado nkwado. Ọ nwere ike ịchịkwa ntọhapụ nke ọgwụ ọjọọ na ahụ mmadụ iji nweta mmetụta ọgwụgwọ. Enwere ike iji ọkwa dị ala viscosity HPMC dị ka nrapado, thickener na onye na-akwụsịtụ, ebe ọkwa viscosity dị elu na-eji HPMC iji kwadebe mbadamba ihe skeleton na-ahapụ, capsules na-adịgide adịgide, na hydrophilic gel skeleton kwadoro-mkpụrụ mbadamba.

Onye na-emepụta ihe nkiri: HPMC nwere ezigbo ihe na-emepụta ihe nkiri, ihe nkiri a na-eme bụ otu, doro anya, siri ike, na ọ dịghị mfe ịgbaso. Ọ nwere ike melite nkwụsi ike nke ọgwụ ahụ ma gbochie mgbanwe. Ọnụ ọgụgụ nkịtị nke HPMC bụ 2% ruo 10%.

Ihe ndị na-emepụta ọgwụ: Cellulose ethers na-arụ ọrụ dị mkpa n'ịkpụzi nkwadebe dị ka ihe ndị na-emepụta ọgwụ, dị ka pellet na-adịgide adịgide, ọkpụkpụ ọkpụkpụ, nkwadebe ntọhapụ nke mkpuchi, capsules na-adịgide adịgide, capsules na-adịgide adịgide, ihe nkiri ọgwụ na-adịgide adịgide, ihe nkiri ọgwụ na-adịgide adịgide. nhapụ nkwadebe na mmiri mmiri kwadoro-ntọhapụ nkwadebe.

Microcrystalline Cellulose (MCC): MCC bụ ụdị cellulose nke a na-ejikarị eme ihe na ụlọ ọrụ ọgwụ, karịsịa na mkpakọ kpọmkwem na usoro granulation akọrọ dị ka mkpirisi rola iji kwadebe mbadamba nkume ma ọ bụ granules.

Bioadhesives: Cellulose ethers, karịsịa nonionic na anionic ether mmepụta dị ka EC (ethylcellulose), HEC (hydroxyethylcellulose), HPC (hydroxypropylcellulose), MC (methylcellulose), CMC (carboxymethylcellulose) ma ọ bụ HPMC (hydroxypropyl) na-eji ọtụtụ ebe. Enwere ike iji polymers ndị a na ọnụ, ocular, vaginal na transdermal bioadhesives, naanị ma ọ bụ jikọtara ya na polymers ndị ọzọ.

Thickeners na Stabilizers: A na-eji ihe nrụpụta cellulose eme ihe n'ọtụtụ ebe iji mee ka ngwọta ọgwụ na-agbasasị dị ka emulsions na suspensions. Ndị polymers ndị a nwere ike ịbawanye viscosity nke ngwọta ọgwụ na-abụghị mmiri dị ka ihe mkpuchi nke organic. Ịbawanye viscosity nke ngwọta ọgwụ nwere ike imeziwanye bioavailability nke nkwadebe n'elu na mucosal.

Fillers: A na-ejikarị cellulose na usoro ya eme ihe dị ka ihe ndochi n'ụdị siri ike dị ka mbadamba nkume na capsules. Ha na-adaba na ọtụtụ ihe ndị ọzọ na-enye nri, ọgwụ na-adịghị ahụkebe, na anaghị agbaze site na enzymes eriri afọ mmadụ.

Ndị na-ekekọta: A na-eji ethers cellulose mee ihe dị ka ndị na-ekekọta ihe n'oge usoro nhazi iji nyere granules aka ịmepụta ma nọgide na-eguzosi ike n'ezi ihe.

Mkpụrụ osisi capsules: A na-ejikwa cellulose ethers mee ihe ọkụkụ, ihe ọzọ na-amasị gburugburu ebe obibi na capsules omenala sitere na anụmanụ.

Usoro nnyefe ọgwụ: Enwere ike iji cellulose ethers mepụta usoro nnyefe ọgwụ dị iche iche, gụnyere njikwa-ntọhapụ na-egbu oge, yana usoro maka ntọhapụ nke saịtị ma ọ bụ oge kpọmkwem.

Ngwa nke cellulose ethers na ụlọ ọrụ ọgwụ na-aga n'ihu na-amụba, na site na mmepe nke ụdị usoro onunu ogwu ọhụrụ na ihe ọhụrụ, a na-atụ anya na ọnụ ọgụgụ nke ahịa ahịa ya ga-abawanye.
