Kedu ka HPMC si agbatị ntọhapụ ọgwụ?

Hydroxypropyl methylcellulose (HPMC) bụ polymer sịntetik nke a na-ejikarị eme ihe na ụlọ ọrụ ọgwụ iji chịkwaa ntọhapụ nke ọgwụ.Ọ bụ ihe na-abụghị ionic, polymer soluble mmiri nke na-emepụta gel n'ihu mmiri.A na-eji HPMC gbanwee ọnụego ntọhapụ nke ọgwụ site na ụdị usoro onunu ogwu, dị ka mbadamba, capsules, na nkwusioru.A na-ejikwa ya dị ka ihe nkedo, mgbasa, na mmanu n'imepụta mbadamba nkume na capsules.

HPMC na-arụ ọrụ site na-akpụ a gel matrix gburugburu ọgwụ ahụ.Nke a gel matrix bụ ọkara permeable, nke pụtara na ọ na-ekwe ka mmiri na-agafe na ya, ma ọ bụghị ọgwụ ọjọọ.Ka mmiri na-agafe na gel matrix, ọ na-eji nwayọọ nwayọọ na-agbaze ọgwụ ndị ahụ, na-ahapụ ha na gburugburu ebe obibi.A maara usoro a dị ka ntọhapụ na-achịkwa mgbasa.

Enwere ike ịchịkwa ọnụego nke ntọhapụ na-achịkwa mgbasa ozi site na ịhazigharị njirimara nke matrix gel HPMC.Dịka ọmụmaatụ, enwere ike ịbawanye viscosity nke matrix gel site na ịgbakwunye HPMC ọzọ, nke ga-ebelata ọnụego nke ntọhapụ na-achịkwa mgbasa.A pụkwara imezi nha nke ọgwụ ahụ, n'ihi na ihe ndị dị nta ga-agbasa ngwa ngwa karịa ihe ndị buru ibu.

Na mgbakwunye na ịchịkwa ntọhapụ nke ọgwụ, HPMC nwekwara ihe ndị ọzọ bara uru Njirimara.Ọ naghị egbu egbu, enweghị mgbakasị ahụ, na enweghị ihe nfụkasị ahụ, na-eme ka ọ dị mma iji na-emepụta ọgwụ.Ọ bụkwa ihe na-abụghị hygroscopic, nke pụtara na ọ naghị etinye mmiri na gburugburu ebe obibi, nke na-enyere aka ịnọgide na-enwe nkwụsi ike nke nhazi ahụ.

HPMC bụ ngwá ọrụ dị irè maka ịchịkwa ọnụego ntọhapụ nke ọgwụ.Site n'ịgbanwe njirimara nke matrix gel HPMC, ọnụego nke ntọhapụ na-achịkwa mgbasa nwere ike ịhazi ya iji zute profaịlụ ntọhapụ achọrọ.Nke a na-enye ohere maka ịmepụta usoro nhazi nke na-ahapụ ọgwụ na-achịkwa na ogologo oge.
