Ribokis 200mg Tablet (Ribociclib) Uses, Dosage, Side Effects & Price in Pakistan

Ribokis 200mg Tablet (Ribociclib) is an oral prescription medicine used in the treatment of certain types of breast cancer. Its active ingredient, ribociclib, belongs to a group of medicines called CDK4/6 inhibitors. It works by slowing signals that help certain cancer cells grow and divide.

Ribokis may be prescribed for suitable patients with hormone receptor-positive (HR-positive), HER2-negative breast cancer. Depending on the condition, ribociclib may be used with hormone treatment such as an aromatase inhibitor or fulvestrant.

Because ribociclib can affect blood counts, liver function and heart rhythm, treatment should be managed by a qualified healthcare professional with appropriate monitoring.

What Is Ribokis 200mg Tablet?

Ribokis 200mg Tablet contains 200mg of ribociclib. It is an oral anticancer medicine designed to target CDK4 and CDK6, two proteins involved in the cell cycle.

Some breast cancer cells depend on these proteins to continue growing. Ribociclib helps slow this process by blocking CDK4/6 activity.

Ribokis is not suitable for every type of breast cancer. The decision to use it depends on factors such as the cancer’s hormone-receptor status, HER2 status, stage and previous treatment.

Available product information identifies Everest Pharmaceuticals Ltd. as the manufacturer of Ribokis 200mg. However, customers should always check the manufacturer and product details printed on the actual pack they receive.

Ribokis 200mg Uses

The main Ribokis 200mg Uses are linked to certain HR-positive and HER2-negative breast cancers.

Ribociclib may be prescribed for:

• Certain early breast cancers with a high risk of recurrence
• Advanced breast cancer
• Metastatic breast cancer
• Other approved HR-positive, HER2-negative breast cancer treatment settings

For selected adults with HR-positive, HER2-negative stage II or III early breast cancer at high risk of recurrence, ribociclib is used with an aromatase inhibitor. For advanced or metastatic disease, it can be used with an aromatase inhibitor or fulvestrant according to the treatment plan.

Your oncologist will decide whether ribociclib is appropriate based on your individual diagnosis.

Use in Early Breast Cancer

For some adults with HR-positive, HER2-negative early breast cancer that has a high risk of returning, ribociclib may be added to hormone treatment.

The aim is to reduce the risk of the cancer returning after the initial treatment.

Use in Advanced or Metastatic Breast Cancer

Ribociclib is also used in certain adults whose HR-positive, HER2-negative breast cancer is advanced or has spread to other parts of the body.

It may be combined with an aromatase inhibitor or fulvestrant depending on the patient’s treatment history and the oncologist’s plan.

How Does Ribociclib Work?

Ribociclib works by blocking CDK4 and CDK6.

These proteins help regulate the cell cycle. When their activity is blocked, certain cancer cells have more difficulty moving through the cell cycle and multiplying.

This makes ribociclib a targeted treatment that works on a specific pathway involved in the growth of certain breast cancer cells.

Ribokis 200mg Dosage

The appropriate Ribokis 200mg dosage is decided by the treating oncologist. The 200mg shown on the pack refers to the strength of one tablet; it does not necessarily mean that one tablet is the complete daily dose.

According to current ribociclib prescribing information:

• For certain early breast cancer treatment, the recommended dose is 400mg once daily, equal to two 200mg tablets.
• For advanced or metastatic breast cancer, the recommended dose is 600mg once daily, equal to three 200mg tablets.

The medicine is generally taken for 21 consecutive days followed by 7 days off, making one 28-day treatment cycle. Dose changes may be needed if certain side effects occur.

Do not choose your dose based only on the tablet strength. Follow the exact dose and schedule prescribed by your oncologist.

How to Take Ribokis 200mg Tablet

Ribociclib can be taken with or without food. It is usually taken at around the same time each day.

Swallow the tablet whole with water. Do not chew, crush or split the tablet.

If you miss a dose or vomit after taking it, the prescribing information advises not taking an additional dose on the same day. The next prescribed dose should be taken at the usual time.

Following the treatment schedule is important, so speak with your healthcare team if you are unsure about a dose.

Ribokis 200mg Side Effects

Like other prescription cancer medicines, Ribokis 200mg can cause side effects. They are not the same for every patient.

Common side effects associated with ribociclib include:

• Low white blood cell counts
• Low neutrophil counts
• Nausea
• Tiredness
• Diarrhea
• Vomiting
• Constipation
• Headache
• Hair loss
• Changes in liver-function tests

Ribociclib can also cause serious problems such as neutropenia, liver toxicity, QT interval prolongation and interstitial lung disease/pneumonitis.

When to Contact a Doctor

Tell your healthcare team promptly if you experience symptoms such as:

• Fever or signs of infection
• Yellowing of the skin or eyes
• New or worsening cough
• Difficulty breathing
• Fainting
• Unusual or irregular heartbeat
• Severe or unusual weakness

Your doctor can decide whether these symptoms need treatment, monitoring or a change in your medicine.

Why Monitoring Is Needed During Treatment

Ribociclib treatment may include regular blood tests, liver-function tests and ECG monitoring.

Blood tests help your doctor monitor blood-cell levels, while liver tests check for possible liver problems. ECG monitoring is important because ribociclib can affect the heart’s electrical activity and prolong the QT interval.

Ribokis 200mg Precautions

Before starting Ribokis 200mg Tablet, tell your oncologist about your medical history and every medicine or supplement you use.

Ribociclib can affect blood-cell counts, liver function and the heart’s electrical activity. Because of this, your doctor may arrange blood tests and ECG monitoring during treatment.

Extra care may be needed if you have:

• Liver problems
• Heart-rhythm problems
• A history of abnormal ECG results
• Low blood-cell counts
• Lung or breathing problems
• Problems with blood minerals such as potassium or magnesium
• Any serious medical condition

Do not reduce, increase or stop your Ribokis dose without talking to your oncologist.

Ribokis 200mg Drug Interactions

Ribociclib can interact with several medicines. Some medicines can increase the amount of ribociclib in your blood, while others can lower its level and affect how it works.

Tell your doctor if you use:

• Antibiotics
• Antifungal medicines
• Heart medicines
• Seizure medicines
• Other cancer medicines
• Prescription medicines
• Over-the-counter medicines
• Vitamins or herbal supplements

Strong CYP3A inhibitors and strong CYP3A inducers can significantly affect ribociclib exposure. Medicines that can prolong the QT interval may also need to be avoided because ribociclib can affect heart rhythm.

Do not start a new medicine or supplement without first checking with your doctor or pharmacist.

Ribokis 200mg and Grapefruit

Avoid grapefruit and grapefruit juice while taking ribociclib unless your healthcare professional gives you different advice.

Grapefruit can affect enzymes involved in the breakdown of ribociclib and may increase the amount of medicine in your body.

If grapefruit is a regular part of your diet, ask your doctor whether you should avoid it during treatment.

Ribokis 200mg and Pregnancy

Ribociclib may cause harm to an unborn baby. Women who can become pregnant should discuss contraception with their healthcare professional before starting treatment.

The current prescribing information recommends using effective contraception during treatment and for at least 3 weeks after the last dose.

If you become pregnant while taking Ribokis, contact your oncologist as soon as possible.

Do not stop your cancer treatment on your own.

Ribokis 200mg and Breastfeeding

Breastfeeding is not recommended during ribociclib treatment.

There is not enough information about the effect of ribociclib on a breastfed infant, and ribociclib and its metabolites can pass into milk in animal studies.

The prescribing information recommends avoiding breastfeeding during treatment and for at least 3 weeks after the final dose.

If you are breastfeeding or planning to breastfeed, discuss the safest option with your doctor.

Ribokis 200mg Storage

For Ribokis 200mg, follow the storage instructions provided on the actual manufacturer’s packaging.
