I-Abemaciclib - Ukusetyenziswa, Idosi, Iziphumo ebezingalindelekanga kunye nokunye

I-Abemaciclib lunyango olujoliswe ngomlomo olusetyenziselwa ukunyanga iintlobo ezithile zomhlaza webele ophucukileyo okanye osasazekayo. Njenge-cyclin-dependent kinase (CDK) 4 kunye ne-6 inhibitor, inciphisa ukukhula kunye nokwahlukana kweeseli zomhlaza ngokuphazamisa imiqondiso ephambili eqhuba ukuqhubela phambili komjikelo weseli. Isebenza ngakumbi kumhlaza webele we-hormone receptor-positive (HR+), i-HER2-negative. Esi sikhokelo sinikezela ngolwazi olupheleleyo nge-Abemaciclib, sigubungela ukusetyenziswa kwayo, idosi, iziphumo ebezingalindelekanga, ukusebenzisana, iingenelo, kunye neempendulo kwimibuzo eqhelekileyo.

Yintoni i-Abemaciclib?

I-Abemaciclib ithintela ngokukhetha i-CDK4 kunye ne-CDK6, ii-enzymes ezilawula utshintsho ukusuka kwisigaba se-G1 ukuya kwi-S somjikelo weseli. Ngokuthintela olu tshintsho, i-Abemaciclib iyayimisa ukwanda kweeseli okungalawulekiyo okubonwa kwiintlobo ezininzi zomhlaza. Ivunyiwe ukuba isetyenziswe kwi-HR+, umhlaza webele we-HER2- oqhubele phambili okanye osasazekayo, nokuba njengonyango oluzimeleyo okanye oludityaniswe nonyango lwe-endocrine.

Ukusetyenziswa kwe-Abemaciclib
