Summary
Ribociclib is used to treat hormone receptor-positive, HER2-negative breast cancer, which is a type of cancer that grows in response to hormones but does not have excess HER2 protein. It is often used in postmenopausal women to help slow the progression of the disease.
Ribociclib works by inhibiting proteins called CDK4 and CDK6, which are involved in cell division. By blocking these proteins, it slows down the growth of cancer cells, helping to control the progression of certain types of breast cancer.
The usual starting dose of Ribociclib for adults is 600 mg once daily. It is taken orally, which means by mouth, preferably in the morning, with or without food. The dose may be adjusted by a doctor based on the patient's response and any side effects.
Common side effects of Ribociclib include nausea, which is feeling sick to your stomach, fatigue, which is extreme tiredness, and low white blood cell counts, which can affect your immune system. These effects vary in frequency and severity among individuals.
Ribociclib can cause liver problems, so regular liver function tests are needed. It may also affect heart rhythm, requiring ECG monitoring. It is contraindicated in patients with severe liver impairment and should be used cautiously in those with heart rhythm issues.
