Inkcazo
I-Terlipressin, enegama lekhemikhali yi-triglycyllysine vasopressin, yinto entsha yokwenza i-vasopressin yexesha elide.Luhlobo lweprodrug, engasebenziyo ngokwayo.Yenziwa yi-aminopeptidase kwi-vivo ukuba "ikhulule" kancinane i-lysine vasopressin esebenzayo emva kokususa iintsalela ze-glycyl ezintathu kwi-N-terminus yayo.Ke ngoko, i-terlipressin isebenza njengendawo yokugcina amanzi ekhupha i-lysine vasopressin ngesantya esizinzileyo.
Impembelelo ye-pharmacological ye-terlipressin kukukontraka kwe-splanchnic vascular smooth muscle kunye nokunciphisa ukuhamba kwegazi kwe-splanchnic (njengokunciphisa ukuhamba kwegazi kwi-mesentery, i-spleen, i-uterus, njl.), ngaloo ndlela ukunciphisa ukuhamba kwegazi kwi-portal kunye noxinzelelo lwe-portal.Ngakolunye uhlangothi, kunokunciphisa i-plasma Umphumo wokugxilwa kwe-renin, ngaloo ndlela ukwandisa ukuhamba kwegazi kwezintso, ukuphucula umsebenzi wezintso kunye nokunyusa ukukhutshwa komchamo kwizigulane ezine-hepatorenal syndrome.I-Terlipressin ngoku kuphela kwechiza elinokuphucula izinga lokusinda kwezigulana ezine-esophageal variceal hemorrhage.Yayisetyenziswa kakhulu kunyango lweklinikhi ye-variceal hemorrhage.Ukongeza, i-terlipressin isetyenziswe ngempumelelo kwisibindi kunye nezintso.Ngokubanzi, kunokwenzeka ukuba idlale indima enenzuzo ekuhlaliseni ukothuka kwe-refractory kunye nokuvuselelwa kwe-cardiopulmonary.Xa kuthelekiswa ne-vasopressin, inefuthe elihlala ixesha elide, ayibangeli iingxaki ezinobungozi, kuquka i-fibrinolysis kunye neengxaki ezinzulu kwi-cardiovascular system, kwaye kulula ukuyisebenzisa (i-intravenous injection), efanelekileyo ngakumbi kukhathalelo olubukhali kunye nolubalulekileyo.Ukuhlangula kunye nonyango lwezigulane ezigula kakhulu.
