Ribociclib is an inhibitor of cyclin-dependent kinases 4 and 6 (CDK4/6), which plays a critical role in cell cycle progression in HR /HER2breast cancer. You can get it as 200 mg tablets with a coating. You should take 600 mg of ribociclib every day for 21 days out of every 28 days.
Each pack has 63 tablets, which is enough for a month’s worth of the recommended dose. It works by stopping CDK4 and CDK6 from doing their thing, which are big players in how cancer cells grow. You might feel tired, sick to your stomach, throw up, have the runs, or find your blood counts are low.
