Isicelo:

I-S-(Carboxymethyl)-L-Cysteine ​​(i-Carbocisteine; i-Carbocysteine) (i-CAS: 638-23-3), iyi-mucolytic enciphisa i-viscosity yesikhwehlela futhi ingasetshenziswa ukusiza ukukhulula izimpawu ze-chronic obstructive pulmonary disorder (COPD) ) kanye ne-bronchiectasis ngokuvumela ogulayo ukuba akhiphe isikhwehlela kalula.I-Carbocysteine ​​​​akufanele isetshenziswe nama-antitussives (izidakamizwa ezicindezela ukukhwehlela) noma imithi eyomisa uketshezi lwe-bronchi.I-Carbocysteine ​​​​ikhiqizwa yi-alkylation ye-cysteine ​​​​ne-chloroacetic acid.Kuyimpahla ebalulekile yezemithi eluhlaza;esetshenziselwa ukuhlanganiswa kwezidakamizwa ezihlukahlukene, inganciphisa ukunamathela kokuphuma kokuphefumula, ukwelapha i-tracheitis engapheli, i-emphysema, isifo sofuba nokunye.
Isetshenziswa ocwaningweni lwe-biochemical, njenge-solubilizer ye-phlegm.Sebenzisa umuthi oncibilikisa i-phlegm, isiyezi esincane ngezikhathi ezithile, isicanucanu, ukuphatheka kabi kwesisu, isifo sohudo, ukopha emathunjini, ukuqubuka kwesikhumba nokunye ukusabela okungekuhle.Sebenzisa ngokuqapha ezigulini ezinomgudu wokugaya ukudla.Lo mkhiqizo uyi-ejenti ye-mucolytic, i-expectorant, nesidakamizwa esilwa nokutheleleka ngamakhala.Isetshenziswa kakhulu ekwelapheni izifo ezifana nesikhwehlela esiwugqinsi, ubunzima be-expectoration kanye nokuvinjwa kwesikhwehlela noqhoqhoqho okubangelwa izifo ezifana ne-bronchitis engapheli kanye ne-asthma ye-bronchial.
I-Carbocysteine ​​i-mucus thinner, umphumela wayo ufana nowe-bromhexine.Ithinta kakhulu ukugcinwa kwezindlala ze-bronchial ezingeni lamaselula.Inganqamula isibopho se-disulfide ye-mucin kufinyi futhi yenze i-sialo mucin ene-viscosity ephansi.Imfihlo iyanda, futhi ukukhiqizwa kwe-high-viscosity fucomucin kuyancishiswa, ukuze i-viscosity ye-sputum iyancipha, okwenza kube lula ukukhishwa kwesikhwehlela.Ukuphathwa komlomo kuqala ukusebenza ngokushesha, futhi umphumela osobala ungabonakala phakathi namahora angu-4 ngemva kokuwuthatha.Isakazwa kabanzi ezicutshini zamaphaphu, futhi ekugcineni ikhishwe emchameni ngendlela yama-prototypes nama-metabolites.
