Uyu muti wandikirwa n'abaganga ukoreshwa cyane mu kuvura indwara idasanzwe ariko ikomeye yitwa pheochromocytoma, aho ibibyimba bitera umuvuduko mwinshi w'amaraso binyuze mu kurekura adrenaline nyinshi cyane n'imisemburo isa nayo.

Nubwo metyrosine atari izina risanzwe nk'indi miti myinshi, ifasha cyane mu kuvura abantu bafite ibibyimba bikora imisemburo. Utekereze nk'aho ushyira feri ku mikorere y'umubiri wawe y'umunaniro w'imbere mu gihe ikora cyane kubera ibyo byibyimba.

Metyrosine ni iki?

Metyrosine ni umuti wa gihanga ukora ubangamira enzyme yitwa tyrosine hydroxylase. Iyi enzyme niyo ishinzwe intambwe ya mbere yo gukora imisemburo y'umunaniro nka dopamine, norepinephrine, na epinephrine (adrenaline) mu mubiri wawe.

Mugihe uhagaritse iyi enzyme gukora neza, metyrosine igabanya neza ikorwa ry'iyi misemburo ikomeye. Ibi bituma bifite agaciro cyane mugihe cyo guhangana n'ibibyimba bikora ibi bintu byinshi cyane, bifasha kugenzura ibimenyetso by'akaga bishobora gutera.

Uyu muti ubarirwa mu cyiciro cy'imiti yitwa enzyme inhibitors, kandi ifatwa nk'ubuvuzi bwihariye busaba ubugenzuzi bw'abaganga. Muganga wawe azagusaba metyrosine nyuma yo kwemeza ko ufite indwara itera ikorwa ry'imisemburo ya catecholamine nyinshi.

Metyrosine ikoreshwa mu kuvura iki?

Metyrosine ikoreshwa cyane mu kuvura pheochromocytoma, igituntu gidasanzwe gikura mu ngingo zikora adrenaline kandi kigakora imisemburo myinshi y'umunaniro. Ibi byibyimba bishobora gutera umuvuduko mwinshi w'amaraso, umuvuduko w'umutima, n'ibindi bimenyetso by'akaga.

Uyu muti akenshi ukoreshwa nk'umuti wo gutegura mbere yo gukuraho ibi byuma mu kubaga. Mu kugabanya imisemburo mbere y'igihe, metyrosine ifasha gukora kubaga neza kandi bikorohera wowe n'ikipe yawe yo kubaga.

Mu bindi bihe, metyrosine ishobora gukoreshwa mu gihe kirekire iyo kubaga bidashoboka ako kanya cyangwa bidashoboka. Ibi bishobora kuba bibaye niba ufite ibyuma byinshi, niba igituntu kiri ahantu hakomeye kubaga, cyangwa niba ukeneye igihe cyo kunoza ubuzima bwawe muri rusange mbere y'igikorwa.
