Emkhakheni wokwenza imithi, umuthi awusona nje isithako samakhemikhali sokwelashwa kodwa uwuhlelo lokulethwa oluklanywe kahle. Ukuze uqonde lolu hlelo, umuntu kufanele aqale acacise umqondo we-Pharmaceutical Excipients. Izinto ezisiza ekwenziweni kwemithi zibhekisela ezintweni ezingasebenzi ezisetshenziswa ekwenziweni kwezidakamizwa okuthi, ngaphandle kwesithako esisebenzayo sokwenza imithi (i-API), zihlolwe ukuphepha. Zisebenza ukulungisa ukwakheka, ukuthuthukisa ukuzinza, ukuthuthukisa ukuqedwa, noma ukulawula izilinganiso zokukhululwa. Uma i-API "iyinhlamvu" elapha lesi sifo, khona-ke abasiza bemithi "bayisibhamu sesibhamu" esithwala futhi sishise; ziyisisekelo esibalulekile samalungiselelo emithi yesimanje.
Phakathi kwenqwaba yezinto ezisizayo zemithi, i-capsule engenalutho ithatha isikhundla esibaluleke kakhulu. Akusona nje isigaba esibalulekile sezinto ezisizayo kodwa futhi iyisithwali esibalulekile esixhuma umuthi nomzimba womuntu. Ubudlelwano phakathi kwezinto ezisiza ekwenziweni kwemithi namaphilisi angenalutho, empeleni, wubunye bolimi "lonke" kanye "nengxenye," kanye "nomsebenzi" kanye "nomphathimandla."
Okokuqala, i-capsule engenalutho isebenza njengommeleli wakudala wezinto ezisizayo zemithi. Njengohlobo oluthile lomsizi wefomu lomthamo, imisebenzi yawo eyinhloko i-"encapsulation" kanye "nokufihla." Izimpushana eziningi ze-API ziba kakhulu noma zinezakhiwo ezicasulayo ezinamandla, okwenza ukumunywa okuqondile kungabekezeleleki. Njenge-excipient, i-capsule engenalutho ixazulula ngokuphelele le nkinga yokunambitheka, ithuthukisa kakhulu ukuthobela isiguli (ukubambelela emishanguzweni). Ngesikhathi esifanayo, ivumela uketshezi noma ukulandelela amanani ezidakamizwa ukuthi aguqulwe abe amafomu aqinile, enze kube lula ukuhlukaniswa, ukupakishwa, kanye nokudosa okunembile.
Okwesibili, ikhwalithi yezinto ezisizayo zemithi inquma ngokuqondile ukusebenza kwama-capsules angenalutho. Amaphilisi angenalutho ngokuvamile akhiqizwa ngezinto zokwakha-zebanga le-polymer ezifana ne-gelatin noma i-hypromellose (HPMC). Ukuhlanzeka, i-viscosity, kanye nokuzinza komzimba kwalezi zinto zonke kuyizimfanelo ezibucayi zekhwalithi (ama-CQAs) yezinto ezisizayo zemithi. Uma igobolondo le-capsule, elisebenza njenge-excipient, lisezingeni eliphansi, isibonelo, uma okuqukethwe komswakama kulawulwa ngendlela engafanele noma amandla emishini enganele, kungaholela ekuqhumeni ngesikhathi sokugcwalisa noma ukuwohloka kwezidakamizwa ngaphambi kwesikhathi. Ngakho-ke, -ikhephuseli elingenalutho lekhwalithi ephezulu liwumkhiqizo{6}wezinto ezisizayo zekhwalithi ephezulu.
Ngaphezu kwalokho, ubuchwepheshe besimanje bokwenza imithi bunikeze amaphilisi angenalutho anezakhiwo ezithuthuke kakhulu njengezihlanganisi zemithi, ikakhulukazi, ukulawula ukukhishwa. Ngokulungisa ukwakheka kwe-capsule, ama-capsules{1}}e-coated noma ama-capsules aqinile{2}}angakhiqizwa. Ezimweni ezinjalo, i-capsule engenalutho ayiselona nje isitsha kodwa ishintsha ibe "iswishi ehlakaniphile" ekwazi ukulawula ukukhishwa kwezidakamizwa kumasayithi athile nangezikhathi ezithile.
Ngokufigqiwe,ama-excipients emithizimelela umqondo obanzi, kuyilapho ii-capsule engenaluthoingelinye lamagatsha anokuqukethwe okuphezulu kobuchwepheshe kanye nenani lesicelo ngaphakathi kwaleso sigaba. Okubili kuxhumene kakhulu: izinto ezisiza ezenza imithi ziyimfanelo eyisisekelo yamaphilisi angenalutho, kuyilapho ikhephusi elingenalutho lisebenza njengemoto ebalulekile lapho abasiza bemithi bebona ukubaluleka komuthi. Ngaphandle-kwezinto ezisiza ezenza imithi zekhwalithi ephezulu, bekungeke kube khona amaphilisi angenalutho aphephile nathembekile, futhi ngenxa yalokho, awekho amalungiselelo ekhephuseli esimanje njengoba siwazi. Uma kukhona imibuzo mayelana namaphilisi angenalutho, Siyakwamukela ukuthintana ne-KornnacCaps.
