Le mveliso inezi-2-i-hydroxypropyl ether i-methyl cellulose, eyimveliso eyenziwe ngokwesiqingatha. Ingaveliswa ngeendlela ezimbini: (1) Emva kokunyanga ii-cotton linters okanye ii-wood pulp fibers nge-caustic soda, zixutywa ne-chloromethane kunye ne-epoxy. I-Propane iyasabela, icocwe kwaye icolwe ukuze ifumaneke; (2) Sebenzisa uhlobo olufanelekileyo lwe-methyl cellulose ukunyanga nge-sodium hydroxide, uphendule nge-propylene oxide phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu ukuya kwinqanaba elifanelekileyo, kwaye uyicocise. Ubunzima be-molecular buqala kwi-10,000 ukuya kwi-1,500,000.
★ Ingcamango yendalo ecocekileyo, iphucula ukugaya kunye nokufunxwa.
★ Umthamo wamanzi uphantsi, yi-5%-8%. Ukumelana nokufuma okunamandla, umxholo awulula ukuwuhlanganisa, kwaye iqokobhe lekhaphu alilula ukuliguqula, liqhekeke, kwaye liqine.
★ Akukho mngcipheko wokusabela okudibeneyo, akukho kusebenzisana, uzinzo oluphezulu, ekubeni i-hydroxypropyl methylcellulose iyinto evela kwi-cellulose, akukho mngcipheko wokusabela okudibeneyo kwezinto zeproteni kwi-gelatin.
★ Iimfuneko eziphantsi zeemeko zokugcina:
Phantse ayiboli kakhulu kwindawo enomswakama omncinci, izinzile kakuhle kumaqondo obushushu aphezulu, kwaye i-capsule ayiguquguquki.
★ Imigangatho efanayo kunye nokuhambelana okuhle:
Ngokuhambelana nemigangatho yesizwe ye-pharmacopoeia, imo, ubungakanani, inkangeleko kunye nendlela yokuzalisa ilingana neekhaphu ezingenanto ze-gelatin, kwaye akukho mfuneko yokutshintsha izixhobo kunye neenxalenye.
★ Umthombo ongengowesilwanyana, akukho mngcipheko wokuba i-growth hormone okanye amayeza ashiyekileyo emzimbeni wesilwanyana.
I-hydroxypropyl methylcelluloseIikhaphu ezingenanto zahlukile kwiikhaphu ze-gelatin zemveli ezingenanto. Ziyi-hydroxypropyl methylcellulose (HPMC) ezenziwe ngepulp yomthi. Ukongeza kwiingenelo zengcamango yendalo ecocekileyo, iikhaphu ezingenanto ze-hydroxypropyl methylcellulose nazo zingaphucula ukufunxwa kunye nokugaywa kweeproteni, amafutha kunye neekhabhohayidreyithi, kwaye zinezibonelelo zobugcisa kunye neempawu ezingenazo iikhaphu ezingenanto ze-gelatin zemveli. Ngokuphuculwa okuqhubekayo kolwazi lwabantu lokuzinyamekela, uphuhliso lokutya imifuno, ukupheliswa kwesifo seenkomo eziphambeneyo, isifo seenyawo nomlomo kwimpilo yabantu, kunye nempembelelo yonqulo kunye nezinye izinto, iimveliso zekhaphu ezicocekileyo zendalo kunye nezityalo ziya kuba yindlela ekhokelayo yophuhliso lweshishini lekhaphu.
