Ulawulo lwesantya sokuphakuzela kunye nemiphumo yako
Ukubaluleka kwesantya sokuphaphazela kwiMixers
Ukulawula isantya sokuvuthuza kwi-pharmaceutical mixers kuchaphazela ngokuthe ngqo ukufana kwesisombululo kunye nokuhambelana komgubo. Ukuxuba okufanayo kuqinisekisa ukuba isithako esisebenzayo se-pharmaceutical (API) sisasazwa ngokulinganayo kwi-lyophilized antibiotic powder, nto leyo ebalulekileyo ekuchanekeni kwedosi kunye nokusebenza kakuhle kwezonyango. Izifundo ezisebenzisa i-V-type mixers, ii-vibratory mills, kunye nezixhobo zokuxuba ze-3-axis zibonisa ukuba isantya esiphezulu sokuvuthuza ngokubanzi siphucula ukufana komxholo, ukucinezeleka, kunye namandla eethebhulethi, ngelixa isantya esingaphantsi kwesiqhelo sinokubangela ukuhamba kakuhle komxube okanye ukusasazwa kwe-API eguquguqukayo. Umzekelo, ukunyuka kwesantya sokuxuba kwi-vancomycin-loaded bone cement kukhokelele ekunyukeni kwe-24% kwi-cumulative antibiotic elution kwiintsuku ezili-15, nto leyo ebonisa ukubaluleka kwezibalo (P < 0.001) kunye nokwenza ngcono iiprofayili zokukhululwa kwamayeza.
Isantya sokudinwa sikwalawula indlela yokwenza ikristale kunye nokunyibilika ngexesha lokwenziwa kwepowder ye-antibiotic. Ukudinwa okufanelekileyo kukhawulezisa ukukhula kwekristale kwaye kunciphisa imida yokusasazeka, kodwa amazinga aphezulu anokuqhekeza iikristale okanye akhuthaze ukunyibilika okungafunekiyo, okuchaphazela ukuthembeka kwenkqubo yokwenza ikristale yeziyobisi.

Ukwenziwa kwekristale yamayeza kunye nomgangatho womgubo
Iindlela zeCrystallization Ngexesha leLyophilization
I-crystallization ngexesha le-lyophilization iqhutywa yi-nucleation kunye ne-growth dynamics, ezichaphazeleka zii-formulation ezininzi kunye nee-process parameters. Izinto ezibalulekileyo ezichaphazela i-crystal nucleation ziquka ukhetho lwe-excipient, i-solute concentration, i-solvent composition, i-cooling rate, kunye ne-agitation speed.
Iindima ezibalulekileyo kwi-Crystallization:
- Iikhompawundi ezifana ne-glycine, i-alanine, i-serine, i-methionine, i-urea, kunye ne-niacinamide zingongezwa kwizisombululo zamanzi ze-antibiotic ukukhuthaza i-nucleation kunye nokulawula utshintsho oluya kwimeko ye-crystalline ngakumbi.
- Izinto ezincedisayo ziqinisa izithako ezisebenzayo zamayeza (ii-API), zixhasa ukuhambelana kwebhetshi, kwaye ziphucula ukwakhiwa kwakhona kunye nexesha lokugcinwa kwemveliso yomgubo we-antibiotic oxutywe ne-lyophilized.
- Ii-cosolvents zendalo—kuquka i-ethanol, i-isopropanol, kunye ne-tert-butyl alcohol—zinyusa ukugcwala okukhulu ngexesha lokuqandisa, zikhawulezisa i-nucleation kunye nokukhula kwekristale. Uxinzelelo oluphezulu lokuqala lwe-solute luyayiphucula le mpembelelo, eboniswe kwii-antibiotics ezifana ne-cephalothin sodium.
Iindlela zoLawulo lweNkqubo:
- Ukulawulwa kokufakelwa kwamanzi kubushushu obungaphantsi kwe-zero (umz., -20 °C) kukhuthaza ukwakheka kwekristale kunye nokukhethwa kwe-polymorph (umz., i-mannitol hemihydrate okanye i-δ form). Ukomiswa kwe-vacuum okulandelayo kubushushu obuphezulu kukhokelela ekuguqukeni kwizigaba ezizinzileyo zekristale, ezifana ne-mannitol α crystal.
- I-In situ Raman spectroscopy kunye ne-cryostage simulations zivumela ukujonga ngokuthe ngqo ezi nguqu zesigaba kunye neziganeko zokukhula kwekristale.
Impembelelo yesantya sokuxinana kunye nokushukuma:
- I-solution viscosity yiparameter ebalulekileyo; i-viscosity ephezulu inokucothisa i-nucleation, ilibazise ukukhula kwekristale, kwaye ichaphazele ubungakanani bekristale yokugqibela.
- Isantya sokushukuma silawula ukuxubana kwe-micromixing, okunokunciphisa ixesha lokungeniswa kwe-nucleation, kukhuthaze ubungakanani obufanayo bekristale, kwaye kukhawulezise izinga lokukhula. Nangona kunjalo, ukuba ukushukuma kugqithisile, iikristale zinokuqhekeka okanye zivelise umlinganiselo ophantsi we-aspect ratios.
- Ukulungiswa kwesantya sokuphakuzela kubalulekile. Umzekelo, ukwanda kokuxutywa kwe-p-acetamidobenzoic acid kunye novavanyo lwe-sodium thiosulfate kukhokelele kwiinuclei ezinkulu kwaye kwanciphisa ukuhlangana okungafunekiyo ngaphandle kokubangela ukuqhekeka okukhulu.
