Faʻamatalaga o oloa
Colistin o se cyclic cationic decapeptide e fesoʻotaʻi ma se faʻamaʻi gaʻo itu itu filifili, o loʻo aʻafia i se vaega o peptides antimicrobial siama faʻapipiʻi tutusa.Colistin sulfate ose polypeptide antibiotic lea e taofia ai siama kalama-negative e ala i le fusifusia i lipopolysaccharides ma phospholipids i totonu o le sela pito i fafo o siama gram-negative.
Colistin sulfate, e lauiloa foi o le colistin sulfate, Kerisiano (Colistin), Polymyxin E(Polymyxin E), antiphytin, paʻepaʻe paʻepaʻe pe toetoe a paʻepaʻe, leai se manogi, tofo oona susu, faigofie ona solu i le vai, soluble i le methanol, ethanol, toetoe lava a le mafai ona solu i totonu. acetone, eter, free alkali solu teisi i le vai.Stable i le PH3-7.5 laina.O le Mycolistin sulfate e gaosia e le Bacillus polymyxoides, lea e malosi lona aafiaga antibacterial i siama gram-negative.E faʻaaogaina e togafitia ai faʻamaʻi o le intestinal e mafua mai i siama gram-negative, ma e faʻaaogaina e fai ma meaʻai faʻaopoopo ma faʻaalia le tuputupu aʻe o le aʻafiaga.O le tuʻufaʻatasiga o le sulfadiazine aafiaga e sili atu.
Galuega ole oloa
Colistin sulfate granules faʻaleleia atili i le mautu o le malosi i meaʻai ma faʻaalia le maualuga o le solubility e ui lava ina latou gaosia e aunoa ma le faʻaaogaina o soʻo se tau taugata poʻo meafaigaluega faʻapitoa.Aemaise lava, colistin sulfate granules e aofia ai le colistin sulfate ma e iai le lautele o le 150 i le 1500m, o se vaega faʻapitoa o le 40 i le 500 cm2/g, o le taimi susu o le 5 minute poʻo lalo ifo ma le susu o le 10% poʻo lalo ifo.
Pharmacodynamics
Colistin o se vailaʻau faʻamaʻi polymyxin.Polymyxins o cationic polypeptides e faʻalavelaveina le sela sela siama e ala i se masini fufulu.Faatasi ai ma le atinaʻeina o vailaʻau faʻaleagaina, e pei o penicillins lautele ma cephalosporins, o le faʻaaogaina o le polymyxin matua na matua lafoaia, sei vagana ai le togafitiga o faʻamaʻi pipisi o le pulmonary multidrug i tagata mamaʻi e maua i le cystic fibrosis.
