I-Colistin Sulfate Pharmacology & Umhlahlandlela Wokwakhiwa Kwemitholampilo Owusizo Wodokotela Bezilwane

I-Colistin sulfate iyi-ejenti yokulwa namagciwane ezwela kakhulu ezinhlakeni eziningi emapulazini emfuyo. Kodwa-ke, abalimi abaningi nodokotela bezilwane bazi igama layo kuphela ngaphandle kokuqonda ukusetshenziswa okujwayelekile nokuqondiwe. Kuphela ngokuqonda kahle izakhiwo zayo zokulwa namagciwane, ukwamukela inhlanganisela eqondiwe kanye nokuphathwa okujwayelekile lapho singakhulisa khona ukusebenza kwayo kwezokwelapha ukuze sithole impendulo esheshayo kanye namazinga aphezulu okuphulukisa.

Imithi yezilwane esebenzayo ayincikile emananini aphansi, kodwa ekuqondeni kahle izakhiwo zemithi. Uma uqonda ngokujulile umuthi, ukukhetha kwakho umuthi kanye nokuphathwa kwawo kunembile kakhulu, kubeka isisekelo esiqinile sokuxilongwa nokwelashwa kwezifo okuphumelelayo. I-Colistin sulfate powder encibilikayo iyisidakamizwa esivamile samathumbu ekwelapheni izinkukhu kanye nemfuyo, kodwa bambalwa ochwepheshe abaphambili abaqonda ngokugcwele izakhiwo zayo kanye nemithetho ejwayelekile yokuhambisana.

1. Ukuhlonza Izinto Ezingavuthiwe kanye Nokwehlukaniswa Kwekhwalithi Yomkhiqizo

I-Colistin sulfate iyi-antibiotiki yemvelo ye-alkaline polypeptide ekhishwa ngokubilisa okuphilayo. Umkhiqizo wayo ohlanzekile ojwayelekile uyimpuphu emhlophe, encibilika kakhulu emanzini ahlanzekile, futhi cishe ayincibiliki kuzo zonke izinyibilikisi eziphilayo. Eminye imikhiqizo yempuphu encibilikayo ye-colistin sulfate ethengiswayo ibonakala iphuzi, ibomvu noma ipinki uma isisusiwe. Imikhiqizo enjalo ayihlangabezani nezindinganiso zokuhlanzeka kwezinto zokusetshenziswa futhi ibalwa njengezimpahla eziphansi, ezinganconywa ukusetshenziswa emtholampilo. Njengoba incibilika kabi ezinyibilikisini eziphilayo, ungayixubi nezinhlobo zoketshezi eziqukethe amazinga aphezulu ezinyibilikisi eziphilayo lapho ulungiselela ukwelashwa okuhlanganisiwe kwamanzi okuphuza. Ngisho noma kungekho ukuhlukaniswa noma imvula ebonakalayo ngemva kokuxuba, umsebenzi wokubulala amagciwane we-colistin sulfate uzoncishiswa kakhulu ngemva kokungena emgodini wokugaya wezilwane nezinkukhu. Kodokotela bezilwane abaphambili abahlose ukuqinisekisa imiphumela yokwelapha, ukubeka phambili imikhiqizo yemithi efanelekile kuyisinyathelo sokuqala esibalulekile. Ukuqondanisa imithi ehambisanayo ngokusekelwe ezicini zayo ze-physicochemical kanye nokulinganisa izinqubo zokuxuba nokuphatha kwakha isiqinisekiso esiyisisekelo semiphumela yokwelapha ezinzile.

2. Indlela Yokubulala Amagciwane kanye Ne-Antibacterial Spectrum

Indlela enamandla yokubulala amagciwane ye-colistin sulfate: Ngemva kokusebenzisa amabhaktheriya, umuthi ulimaza isakhiwo se-membrane yeseli yama-Gram-negative bacteria ngokungenakulungiseka futhi wandisa kakhulu ukuvuleka kwe-membrane. Izinto ezibalulekile zangaphakathi kweseli ezifaka phakathi ama-potassium ion, ama-calcium ion, ama-amino acid, ama-purines nama-pyrimidines aqhubeka nokuvuza, acime izinto zenuzi nama-ribosome futhi abangele ukusheshisa kwe-bacterial lysis nokufa. Lo muthi une-spectrum encane kakhulu ye-antibacterial futhi usebenza kuphela ngamandla ngokumelene nama-pathogens e-Gram-negative avamile ekuzaleni, okuhlanganisa i-Escherichia coli, i-Salmonella, i-Proteus, i-Shigella, i-Pasteurella kanye ne-Pseudomonas aeruginosa. Imodi yawo ehlukile ye-bactericidal yenza kube nzima ngama-bacterial pathogenic ukuthuthukisa ukumelana nemithi ngokumelene ne-colistin sulfate. Ngaphezu kwalokho, awunawo ukumelana okuphambene nama-antibiotic amaningi anemikhawulo embalwa yokuhambisana, okuvumela izinhlelo zokuhlanganisa eziguquguqukayo.

3. Izici Zokumunca E-Vivo Zesiqondiso Semithi Ehlanganisiwe

Uma inikezwa ngomlomo ezilwaneni ezinempilo nasezinkukhu, i-colistin sulfate ayingeni kahle emucosa yamathumbu ukuze ingene ekujikelezeni kwegazi. Ezimweni ze-enteritis noma i-enterotoxemia enolwelwesi lwamathumbu olulimele, olungangeni kakhulu, cishe u-10% womuthi ophuzwayo ungamuncwa kalula egazini. Lesi sici sinikeza isisekelo semfundiso yokwelapha okuhlangene okuqondiswe ezifweni zamathumbu eziyinkimbinkimbi ukutheleleka kwesibili komzimba. Umuthi ugcina ukuhlushwa okuphezulu kwendawo ezilondeni zamathumbu ukuze uvimbele amagciwane, kuyilapho ingxenye encane emuncwayo ilawula ukutheleleka kwesibili komzimba, iletha imiphumela emibili yokwelapha.

4. Amafomula Okuhambisana Nemitholampilo Ajwayelekile Ahambisanayo

CUkwelashwa nge-ombination ye-colistin sulfate ene-sulfonamides kanye ne-trimethoprim potentiators kuletha imiphumela evelele yokubulala amagciwane ngokumelene nezifo ezibangelwa yi-Escherichia coli, i-Pasteurella, i-Salmonella, i-Klebsiella pneumoniae kanye ne-Pseudomonas aeruginosa. Umphumela wokwelapha ophelele ungcono kakhulu kunokuphathwa kwe-single colistin sulfate.

Njengomuthi wezilwane ochwephesheI-OEMumenzi ohlinzeka ngemikhiqizo yochungechunge lwe-colistin sulfate yomhlaba wonkeB2Babasabalalisi bemfuyo,I-HEBEI LIHUA PHARMACEUTICAL CO., LTDinikeza ukwesekwa okugcwele okuhlanganisa ukuhlolwa kwezinto zokusetshenziswa, ukwakheka okwenziwe ngokwezifiso kanye nokunikezwa okuzinzile kwenqwaba yezinkukhu, izingulube, izimvu kanye nokufuya amathole. Xhumana nathi ukuthola amaphepha edatha obuchwepheshe kanye nezixazululo zokubambisana ze-OEM.
