KISQALI FEMARA CO-PACK consists of ribociclib 200 mg film-coated tablets co-packaged with letrozole 2.5 mg tablets. Ribociclib KISQALI (ribociclib) is a kinase inhibitor. Ribociclib succinate is a light yellow to yellowish brown crystalline powder. The chemical name of ribociclib succinate is: Butanedioic acid—7-cyclopentyl- N , N -dimethyl-2-{[5-(piperazin-1-yl) pyridin-2-yl]amino}-7 H -pyrrolo[2,3- d ]pyrimidine-6-carboxamide (1/1). The molecular formula for ribociclib succinate is C 23 H 30 N 8 O.C 4 H 6 O 4 and the molecular weight is 552.64 g/mol [Free base: 434.55 g/mol] . The chemical structure of ribociclib is shown below: KISQALI film-coated tablets are supplied for oral use and contain 200 mg of ribociclib free base (equivalent to 254.40 mg ribociclib succinate). The tablets also contain colloidal silicon dioxide, crospovidone, hydroxypropylcellulose, magnesium stearate, and microcrystalline cellulose.
