Vim li cas Qe Lecithin siv hauv Propofol?

Cov ntu hauv qab no piav qhia vim li cas cov qe ntshiab lecithin hmoov siv hauv Propofol formulations. Cov laj thawj suav nrog kev tsim qauv, kev nyab xeeb hauv chaw kho mob, kev ua haujlwm tshuaj, thiab kev tsim khoom lag luam.

Haum rau Formulation

Kev txhaj tshuaj Propofol yog roj - hauv - dej emulsion. Nws muaj cov roj taum ua kom zoo, dej rau kev txhaj tshuaj, thiab glycerin. Hom kab ke no yog ib txwm tsis ruaj khov. Yog tsis muaj lub siab - zoo emulsifier, cov roj tee tuaj yeem sib sau ua ke, sib cais, flocculate, lossis khom. Cov teeb meem no tuaj yeem ua rau cov khoom lag luam tsis ua haujlwm thiab ua rau muaj kev nyab xeeb ntxiv. Ntuj qe lecithin hmoov yog ib qho zoo tagnrho emulsifier rau cov qauv no.

Qe lecithin feem ntau muaj siab -purity phosphatidylcholine thiab ib qho tsim nyog ntawm phosphatidylethanolamine. Cov phospholipids no muaj cov qauv amphiphilic ntuj. Qhov kawg hydrophobic khi rau Propofol hauv cov roj theem. Qhov kawg hydrophilic cuam tshuam nrog theem dej. Qhov no tsim ib txheej tiv thaiv muaj zog nyob ib ncig ntawm txhua cov roj tee thiab pab tiv thaiv kev sib sau ua ke.

Qe lecithin kuj tseem pab tswj kom muaj qhov ruaj khov emulsion particle loj li ntawm 150-200 nm, uas ua tau raws li cov cai ntawm pharmacopoeia. Qhov loj me me no haum rau kev lag luam siab -siab homogenization. Cov khoom kawg yog sib xws thiab nyob twj ywm tsis muaj nag lossis daus, discoloration, thiab theem sib cais.

Tsis tas li ntawd, ntuj qe lecithin txhawb nqa ntev -cov khoom lag luam ruaj khov. Propofol emulsions tuaj yeem nyob ruaj khov rau 24-36 lub hlis nyob rau hauv qhov chaw cia khoom. Nws kuj muab batch zoo heev - rau -batch sib xws. Piv nrog rau ntau cov hluavtaws emulsifiers thiab ntau cov kua lecithin, qe lecithin muaj kev ruaj ntseg zoo dua rau kev lag luam loj -scale kev tsim tshuaj.

Biocompatibility zoo heev

Intravenous formulations yuav tsum muaj kev nyab xeeb heev excipients. Lawv yuav tsum muaj kev tsis haum tshuaj tsawg, ua rau tsis muaj vascular irritation, ua kom tag nrho metabolized nyob rau hauv lub cev, thiab tsis muaj cumulative toxicity. Qe yolk lecithin ua tau raws li cov cai no. Nws cov khoom yog sib xws nrog tib neeg lub cev. Qhov no ua rau nws zoo tagnrho excipient rau kev nyab xeeb kev kho mob siv propofol.

Ntuj qe yolk lecithin yog purified los ntawm nqaij qaib qe yolks. Nws cov qauv phospholipid zoo ib yam li tib neeg cov cell membranes. Nws tsis ua rau muaj kev tiv thaiv kab mob tom qab txhaj tshuaj. Nws kuj muaj cov protein txawv teb chaws tsawg heev. Qhov no yuav pab txo qhov kev pheej hmoo ntawm kev tsis haum tshuaj. Piv nrog cov kua lecithin, ntuj qe qe lecithin muaj kev pheej hmoo ua xua. Nws haum rau cov neeg laus, menyuam yaus, cov laus, thiab cov neeg mob hnyav.

Cov emulsion ua nrog cov qe qe qe lecithin muaj lub siab osmotic ze rau ntawm tib neeg cov ntshav. Thaum ua ke nrog glycerol, nws pab txo qis vascular irritation thaum lub sij hawm propofol infusion. Nws tuaj yeem txo qhov mob, phlebitis, vascular to, thiab cov ntaub so ntswg puas.

Ntuj Qe yolk lecithin tau tawg tag los ntawm lub cev lipids metabolism. Nws tsis khaws cia hauv lub cev. Nws tsis ua kom lub siab ua haujlwm ntawm lub siab lossis lub raum. Nws kuj tsis cuam tshuam rau kev ua haujlwm ntawm cov hlab plawv lossis cov hlab ntsws. Cov txiaj ntsig zoo no phim cov yam ntxwv ntawm propofol raws li luv luv - ua cov tshuaj loog nrog cov residue tsawg thiab muaj kev ruaj ntseg profile.

Kev tso tshuaj ruaj khov:

Propofol cov txiaj ntsig tseem ceeb hauv kev kho mob yog nws qhov pib sai, cov nyhuv ruaj khov, rov qab sai, thiab tswj tau yooj yim. Cov txiaj ntsig no nyob ntawm kev xa tshuaj ruaj khov. Ntuj Qe yolk lecithin pab kom lub formulation ruaj khov. Nws txhawb kev tso tshuaj zoo ib yam thiab txhim kho kev nyab xeeb.

• Ua ntej, qe qe lecithin tsim ib txheej tiv thaiv lipid nyob ib ncig ntawm Propofol molecules.

Qhov no tso cai rau cov tshuaj tso tawm tusyees thaum lub sij hawm intravenous infusion. Nws pab txo cov kev mob tshwm sim sai sai xws li ntshav siab, ua pa nyuaj siab, thiab bradycardia. Nws kuj tseem pab tiv thaiv qhov pib tshuaj loog qeeb lossis qaug zog sedation los ntawm kev tso tshuaj qeeb.

• Qhov thib ob, lub qe qe qe lecithin emulsion muab qhov zoo ib yam ntawm cov khoom tsim tawm.

Qhov no pab tswj kev ua haujlwm pharmacokinetic ruaj khov. Ntuj Qe yolk lecithin txhawb kev txhim khu kev qha thaum lub sij hawm tshuaj loog induction, tshuaj loog kho, thiab ICU sedation. Cov kws kho mob tuaj yeem tswj cov koob tshuaj thiab cov tshuaj infusion kom raug.

• Thaum kawg, qe qe lecithin yog tshuaj ruaj khov.

Nws tsis hnov ​​​​mob nrog Propofol lossis hloov nws cov qauv molecular lossis kev ua haujlwm tshuaj. Nws kuj tseem siv tau nrog cov tshuaj kho mob, suav nrog lidocaine, cov tshuaj tiv thaiv neuromuscular, thiab nqus tshuaj loog. Nws tsis ua rau cov tshuaj antagonism lossis tsis xav tau kev sib cuam tshuam. Qhov no ua rau nws haum rau kev sib xyaw ua ke hauv kev kho mob.

Mature Compliance

Ntawm qib kws tsim tshuaj thiab kev tswj hwm, qe qe lecithin tau zoo -tsim cov qauv tshuaj pharmacopoeia, cov ntaub ntawv kho mob dav dav, thiab muaj peev xwm muaj peev xwm ua tau zoo. Nws yog ib qho tseem ceeb excipient rau kev ua raws li kev tsim khoom thiab kev lag luam ntawm propofol formulations.

• Los ntawm kev pom kev ua raws cai

Tuam Tshoj Pharmacopoeia, Tebchaws Asmeskas Pharmacopeia, thiab European Pharmacopoeia tag nrho cov npe ua kom zoo nkauj ntuj qe qe lecithin raws li tus tsim emulsifying excipient rau propofol txhaj tshuaj emulsions. Nws cov qauv zoo, cov txheej txheem tsim khoom, thiab kev tswj hwm impurity yog cov qauv zoo. Lawv ua tau raws li cov cai tswj hwm rau kev sau npe tshuaj, kev tswj hwm kev tsim khoom, thiab kev soj ntsuam kev lag luam. Piv nrog cov emulsifying excipients tshiab, ntuj phospholipid los ntawm qe qe ecithin muaj keeb kwm ntev ntawm kev siv tshuaj thiab cov ntaub ntawv soj ntsuam kev nyab xeeb.
