Ngwa Okwu Mmalite nke HPMC na Pharmaceutics

Hydroxypropyl methylcellulose (HPMC) bụ ihe nrụpụta cellulose nke nwetagoro ngwa ngwa na ụlọ ọrụ ọgwụ n'ihi ihe pụrụ iche ya, gụnyere mmiri solubility, biocompatibility, na ike imepụta ihe nkiri. Ụfọdụ ngwa a na-ahụkarị nke HPMC na ọgwụ ọgwụ gụnyere:

Ihe mkpuchi mbadamba: A na-eji HPMC dị ka onye na-emepụta ihe nkiri na mkpuchi mbadamba iji meziwanye ọdịdị, nkwụsi ike, na uto nke mbadamba nkume ahụ. Ọ nwere ike inye mkpuchi dị nro na nke edoghị anya nke na-echebe ihe na-arụ ọrụ site na ihe ndị dị na gburugburu ebe obibi, dị ka mmiri na ọkụ, ma na-egbochi mbadamba nkume ka ọ ghara ịrapara na ihe nkwakọ ngwaahịa. A na-ejikwa HPMC dị ka ihe nkedo n'ụdị mbadamba nkume, iji mee ka mbadamba nkume sie ike na nkesa.

Sistemụ ntọhapụ a na-achịkwa: A na-eji HPMC dị ka ihe matriks na mmepe nke sistemụ ntọhapụ a na-achịkwa, dị ka mbadamba ụrọ na capsules na-adịgide adịgide. Ọ nwere ike ịmepụta matrix hydrophilic nke na-achịkwa ọnụego ntọhapụ ọgwụ, site na ọzịza na nwayọọ nwayọọ na-agbaze n'ime mmiri eriri afọ. Enwere ike gbanwee profaịlụ ntọhapụ ọgwụ site n'ịgbanwe mkpokọta HPMC, ịdị arọ molekul, na ogo nnọchi.

Usoro anya: A na-eji HPMC dị ka ihe na-akwalite viscosity na onye na-akwụsịtụ n'ụdị anya, dị ka nsị anya na mmanu. Ọ nwere ike imeziwanye bioavailability na oge njigide nke ihe na-arụ ọrụ na anya, site n'ịbawanye viscosity na mucoadhesive Njirimara nke nhazi.

Usoro ihe dị n'elu: A na-eji HPMC dị ka ihe na-eme ka ọ dị arọ na emulsifier n'ụdị usoro, dị ka ude, gels, na lotions. Ọ nwere ike inye ọdịdị dị nro ma kwụsie ike na nhazi ahụ, ma na-eme ka ntinye akpụkpọ ahụ dịkwuo mma na ntọhapụ ọgwụ. A na-ejikwa HPMC dị ka onye na-ahụ maka bioadhesive na transdermal patches, iji kwalite nrapanye akpụkpọ ahụ na nsị ọgwụ.

N'ozuzu, HPMC bụ polima nwere ike inye ọtụtụ uru na mmepe nke usoro ọgwụ, gụnyere ntọhapụ ọgwụ emelitere, bioavailability, nkwụsi ike, na nnabata onye ọrịa. Nchekwa ya, biocompatibility, na ịdị mfe nke ojiji na-eme ka ọ bụrụ nhọrọ na-ewu ewu maka ndị na-emepụta ọgwụ na gburugburu ụwa.
