Nyob ntawm kev tsim, koob tshuaj, thiab co-cov tshuaj ntxiv,melatonin hmoovfeem ntau pib ua kom pom cov kab ke ntsuas tau 20 mus rau 60 feeb tom qab tswj hwm.
Nkag siab txog Melatonin Powder Onset
Hauv kev sib piv lub sij hawm coj los ntawm cov hmoov melatonin los ncaws hauv, cov tuam txhab tsim khoom, cov neeg tsim khoom, thiab cov neeg yuav khoom ntawm cov khoom xyaw yuav tsum paub qhov txawv ntawm cov khoom tsim qauv thiab cov sij hawm physiological. Melatonin yog ib qho khoom noj khoom haus neurohormone nrov. Nws yog lub sijhawm rau kev ua haujlwm hauv cov khoom tiav raws li cov khoom siv hmoov, uas nyob ntawm cov khoom ntawm cov khoom, cov khoom ntxiv, thiab daim ntawv xa tawm tsis zoo li lub sijhawm ua haujlwm. Kev paub txog kinetics ntawm melatonin hmoov dispersion thiab nqus nyob rau hauv ib qho chaw muaj peev xwm qhia tau rau cov formulation tswv yim yuav tsum tau siv kom tau raws li qhov xav tau dissolution qhov rais.
Particle yam ntxwv thiab Dissolution
Particle Loj Distribution
Qhov kev sib cais ntawm cov khoom zoo hauv cov kua hauv plab simulants yog siab dua vim qhov loj dua qhov chaw.
Cov feem loj dua tuaj yeem nthuav tawm qeeb qeeb, uas yuav cuam tshuam rau qhov pib tshwm sim thaum cov hmoov muab tso rau hauv cov tshuaj ntsiav lossis ntsiav tshuaj.
Crystallinity / Amorphous.
Muab qhov chaw hauv amorphous melatonin hmoov, cov hmoov amorphous feem ntau yuav ua rau ntub dej sai thiab tawg.
Cov hmoov crystalline heev tuaj yeem ua kom ntub dej los ntawm kev siv cov khoom siv ntxiv kom ua tiav cov khoom tsim tawm.
Kev txiav txim siab Flowability
Cov khoom ntws zoo muab txawm tias tuag puv hauv cov ntsiav tshuaj xovxwm thiab qhov hnyav zoo hauv cov tshuaj ntsiav, uas ua rau cov batch ruaj khov - mus rau -batch profile pib.
Formulation Factors uas cuam tshuam rau ncaws-hauv lub sijhawm
Excipient xaiv
Rapid-disintegration excipients (piv txwv li, superdisintegrants) ua rau daim ntawv nyuaj npaum li sai tau, uas yuav ua rau melatonin muaj rau cov txheej txheem nqus sai dua.
Ntws condensers muaj peev xwm ua kom qeeb ntawm cov txheej txheem ntawm kev tawg, txuas txoj hauv kev mus rau qhov chaw ua haujlwm.
Kev xa tawm Format
Yog tias tsis muaj binders tiv thaiv kev nkag mus ntawm cov kua, melatonin hmoov muaj nyob rau hauv cov tshuaj ntsiav tuaj yeem hydrate sai dua li cov ntsiav tshuaj compressed.
Optimized disintegrants nyob rau hauv cov ntsiav tshuaj compression ncaj qha tuaj yeem nyob ze rau tus cwj pwm tsis zoo ntawm cov tshuaj ntsiav.
Reconstitution hmoov sticks los yog sachets kuj muab tau ceev tshaj dispersion nyob rau hauv tov nrog dej ua ntej noj; Raws li cov khoom siv raw, melatonin hmoov siv hauv cov tshuab no yuav tsum tau ua pov thawj tias yog soluble thiab ruaj khov.
Excipients Wetting Affectants.
Hydrophilic cov cab kuj (xws li, PEG, PVP) nce kev sib cuag nrog aqueous xov xwm, uas ua rau kom muaj kev sib cais tsis sib xws.
Roj. Raws li excipients yuav ua rau kom ntub dej thiab retard dispersion tshwj tsis yog thaum judiciously siv nyob rau hauv cov mis.
Dose thiab Concentration Dependencies
Label Claim vs. Functional Dose
Formulation tsim tsis tau kom meej meej dissolution dynamics txij li thaum nce tus nqi ntawm melatonin hmoov ib pab yuav cuam tshuam rau cov dynamics.
Kev sib xyaw ua ke nrog excipients tiv thaiv cov koob tshuaj loj dua los ntawm kev cuam tshuam nrog kev tawg ntawm cov hmoov.
Kev cuam tshuam ntawm Agglomerates
Agglomeration nyob rau hauv tej melatonin hmoov yog tsis tswj, yog li ua rau lub uneven dissolution ntawm no compound, uas ua rau lub sij hawm coj mus ncaws nyob rau hauv tsawg kwv yees ntawm batches.
Kev ruaj ntseg thiab ntim khoom cuam tshuam
Moisture Sensitivity
Melatonin hmoov yog hygroscopic; Nws yog rhiab heev rau cov av noo, thiab nws cov yam ntxwv ntws thiab dissolution cuam tshuam.
Cov ntim khoom siv hauv kev lag luam muaj cov txheej txheem dej noo noo, thiab cov khoom siv desiccants pab tswj cov txheej txheem pib sib xws.
Lub teeb thiab tshav kub raug
Melatonin tsis hloov pauv tau yooj yim, txawm hais tias ntev - cov av noo los yog kub siab tuaj yeem cuam tshuam rau crystal cwj pwm thiab yog li ntawd tuaj yeem hloov pauv.
Kev lag luam daim ntawv thov thiab kev tswj kom zoo
Cov cwj pwm zoo rau kev siv B2B
Kev txiav txim siab qhov ntau thiab tsawg, D90 qhov tseem ceeb, thiab qhov ntom ntom ntawm Melatonin hmoov ua rau muaj kev ntseeg siab ntawm kev ntsuas kev sib cais.
Hauv - cov txheej txheem kuaj xyuas yog siv los tshuaj xyuas cov khoom siv tshuaj sib xws thiab lub sijhawm tawg, uas muab cov ntaub ntawv hais txog dab tsi tshwm sim thaum melatonin muaj tom qab kev tswj hwm.
Hauv Kev Tshawb Fawb Cov Khoom Siv Ua tiav.
Ib txwm nyob rau hauv vitro dissolution profiling muab cov ntaub ntawv qhia txog tus nqi ntawm melatonin raug tso tawm rau hauv ib hom ntawv nyob rau hauv simulated gastrointestinal mob.
