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.
