Ikhadi i-bei oxytocin (i-Carbetocin) iwuhlobo lokuhlanganiswa kokusebenza isikhathi eside okunezici zokuqukethwe kwe-agonist oxytocin 8 peptide, izakhiwo zayo zomtholampilo nezemithi ezifana nokukhiqiza kwemvelo i-oxytocin.Njenge-oxytocin, i-cabetin ibophezela kuma-oxytocin receptors emsipha obushelelezi wesibeletho, okubangela ukufinyela okunesigqi kwesibeletho, okwandisa ukuvama kwaso futhi kwandise ukushuba kwesibeletho phezu kokufinyela kwasekuqaleni.Amazinga ama-oxytocin receptors esibelethweni aphansi ngesikhathi sokukhulelwa futhi anda ngesikhathi sokukhulelwa, akhuphuke kakhulu ekuzalweni.Ngakho-ke, i-cabetin ayinawo umthelela esibelethweni esingakhulelwe, kodwa inokufinyezwa okusebenzayo kwesibeletho esikhulelwe kanye nesibeletho ngemva kokuzalwa.Kuphakathi kwe-intravenously noma ngaphakathi, isibeletho sifinyela ngokushesha, sifinyelele amandla aqondile phakathi nemizuzu emi-2.Umthamo owodwa we-capetin efakwe emthanjeni uyasebenza esibelethweni cishe ihora elilodwa, okwanele ukuvimbela ukopha kwangemva kokubeletha ngokushesha ngemva kokubeletha.Imvamisa kanye nobukhulu bokufinyela ngemuva kokuphathwa kwe-carpetin kwangemva kokubeletha kwakunde kune-oxytocin.Ucwaningo luye lwabonisa ukuthi lapho unikezwa umthamo owodwa we-100μg emithanjeni ngokushesha ngemva kokuhlinzwa ngaphansi kwe-epidural noma i-lumbar anesthesia, i-carbetin iphakeme kakhulu kune-placebo ekuvimbeleni i-hypotonia yesibeletho kanye nokunciphisa ukopha kwangemva kokubeletha.I-Carpeine enikezwe esikhathini sokuqala kwangemva kokubeletha ingase futhi ikhuthaze ukululama kwesibeletho.
I-Cabetin ibophezela kuma-oxytocin receptors emsipha obushelelezi wesibeletho ukuze ibangele ukuthi isibeletho sifinyezeke ngendlela enesigqi, okwandisa ukufinyela kwaso futhi kwandise ukushuba kwesibeletho.Umthamo owodwa we-carbetin unganikezwa ngokushesha ngemva kokubeletha ukuvimbela ukopha kwangemva kokubeletha.Kutholakale ukuthi umjovo we-oxytocin ngemuva kokubeletha uhlanganiswe nokuphathwa kwe-cabetin kungavimbela ngempumelelo ukulahleka kwegazi kwangemva kokubeletha.Ngemuva kwesigaba sokuhlinzwa, ukusetshenziswa kwe-cabetin kuhlanganiswe ne-oxytocin kungaqinisa ukufinyela kwesibeletho, ukunciphisa inani lokulahlekelwa kwegazi ngemva kwesigaba sokuhlinzwa, umphumela ungcono nakakhulu kune-hemabate.Kwabesifazane abane-cicatritic uterus, i-placenta previa nezinye izici eziyingozi kakhulu zokopha kwangemva kokubeletha, i-carbetin ingavimbela ngempumelelo ukuvela kokuphuma kwegazi kwangemva kokubeletha.Isetshenziselwa i-elective epidural noma i-lumbar anesthesia ngemva kwesigaba sokuhlinzwa ukuvimbela ubuthakathaka bokufinyela kwesibeletho kanye nokuphuma kwegazi kwangemva kokubeletha.
