🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively inhibiting cyclin-dependent kinases 4 and 6, which are enzymes that control the progression of cells from the G1 phase to the S phase of the cell cycle. In hormone receptor positive breast cancer, the cyclin D-CDK4/6-retinoblastoma pathway is often overactive, driving uncontrolled cell division. By blocking CDK4 and CDK6, this medicine helps prevent the phosphorylation of the retinoblastoma protein, thereby stopping cancer cells from dividing and slowing tumour growth.

👴 Special Considerations for Elderly
💡 For Patients Above 65
Elderly patients (above 65 years) may be more susceptible to side effects such as fatigue, infections, and heart rhythm changes. Close monitoring of blood counts, liver function, and ECG is recommended. Dose adjustments should be based on overall health, kidney function, and liver function. Falls and dehydration should be avoided.
🤰 Pregnancy Planning (TTC)
This medicine can cause harm to an unborn baby. Women of childbearing potential should use effective contraception during treatment and for at least 3 weeks after the last dose. If you are planning to become pregnant, discuss with your oncologist well in advance. Pregnancy should be avoided during treatment. Men with female partners of childbearing potential should also use effective contraception during treatment and for at least 3 weeks after the last dose.
🏥 Post-Surgery Considerations
If you are scheduled for surgery, inform your surgeon and oncologist that you are taking this medicine. It may need to be temporarily stopped before surgery due to the risk of bleeding and infection from low blood counts. Your doctor will advise you on when to stop and when to restart after surgery.
🦷 Dental Procedures
Inform your dentist that you are taking this medicine before any dental procedure. Low blood counts can increase the risk of bleeding and infection. Your dentist may recommend postponing non-urgent procedures until your blood counts recover. Maintain good oral hygiene to prevent infections.
💚 Lifestyle Tips for Better Results
🏋️ Exercise Considerations
While taking this medicine, you may experience fatigue, dizziness, or low blood counts, which can affect your ability to exercise safely. Avoid strenuous or high-impact activities that could increase the risk of bleeding or injury, especially if your platelet counts are low. Consult your doctor before starting any new exercise regimen. Light to moderate activities like walking or stretching are generally safe if you feel well.
🥗 Diet Recommendations
💼 Impact on Daily Work & Life
This medicine may cause fatigue, dizziness, and nausea, which can affect your ability to work or perform daily activities. Avoid driving or operating heavy machinery if you feel tired or dizzy. Discuss with your employer about flexible working hours or remote work options if needed. Most patients can continue with light to moderate work activities, but listen to your body and rest when necessary.
🛑 When to Stop This Medicine
Do not stop taking this medicine without consulting your oncologist. Treatment is usually continued as long as the cancer is controlled and side effects are manageable. Your doctor may temporarily interrupt or permanently discontinue treatment if you develop serious side effects such as severe QT prolongation, severe liver injury, or persistent low blood counts. Always seek medical advice before making any changes.
📅 Long-Term Use Effects
Long-term use of this medicine may lead to persistent low blood counts, chronic fatigue, and cumulative liver stress. Regular monitoring of blood counts, liver function, and heart rhythm is essential throughout treatment. Some patients may experience prolonged QT interval, which requires ongoing ECG monitoring. The long-term safety beyond several years of treatment is not fully established. Your oncologist will periodically reassess the benefits and risks of continuing treatment.
🌿 Non-Medicine Approaches
