Crizanlizumab ikora ite?

Crizanlizumab ikora ibuza P-selectin, poroteyine ikora nk'uburyo bwo gufata molekile imbere mu miyoboro y'amaraso yawe. Iyo P-selectin ikora, ituma uturemangingo tw'amaraso, utunyangingo tw'amaraso, n'ibindi bintu bifatana ku nkuta z'imiyoboro y'amaraso no ku bandi.

Muri iyi ndwara ya selile ya sikeri, iyi nzira yo gufatana iragoye cyane kuko uturemangingo twawe tw'amaraso tumaze guhinduka kandi dukunda gufatwa byoroshye. Mu kubuza P-selectin, crizanlizumab ifasha kwirinda iyi traffic jam y'uturemangingo itaraba.

Ibi bifatwa nk'umuti ukomeye mu buryo bwo gukora ku kintu cyihariye, ariko ukora buhoro buhoro uko igihe kigenda, aho gutanga ubufasha bwihuse. Ibyo bikorwa bigenda byiyongera buhoro buhoro, niyo mpamvu ukeneye gutererwa inshuro nyinshi mbere yo kubona inyungu zose.

Nkwiriye gufata crizanlizumab nte?

Crizanlizumab itangwa nk'urushinge rwo mu rwungano rw'amaraso mu gihe cy'iminota 30 mu kigo cy'ubuvuzi. Uzahabwa umuti rimwe mu byumweru bine, kandi ikipe yawe y'ubuvuzi izakugenzura mu gihe cyo gutererwa no nyuma y'urushinge rwa buri gihe.

Mbere yo guterwa urushinge, ushobora guhabwa imiti yo gutegura kugira ngo ifashe kwirinda ibimenyetso by'uburwayi. Ibi bishobora kuba harimo antihistamines, acetaminophen, cyangwa corticosteroids. Muganga wawe azakumenyesha niba ukeneye iyi miti yongereweho.

Ntabwo ukeneye kwiyiriza ubusa mbere yo kuvurwa, kandi urashobora kurya uko bisanzwe ku munsi wo guterwa urushinge.
