What is Qinlock 50 mg Tablet?

Qinlock 50 mg Tablet contains ripretinib, a targeted cancer therapy used in the management of advanced gastrointestinal stromal tumors (GIST). It is typically prescribed to patients who have already received treatment with other medicines but need an additional option for controlling tumor growth. Qinlock works by blocking abnormal proteins that drive the growth and spread of cancer cells.

Medical Uses of Qinlock

Qinlock is mainly prescribed for:

  • Advanced GIST (Gastrointestinal Stromal Tumors) – especially in cases where other treatments have failed.

  • Targeted therapy – It helps slow down or stop the growth of cancer cells by inhibiting multiple mutations involved in tumor development.

It is not a first-line treatment and is usually considered when other therapies are no longer effective.

Dosage and Administration

  • Recommended Dose: The usual adult dose is 150 mg once daily, which equals three tablets of 50 mg each.

  • How to Take: Qinlock can be taken with or without food, preferably at the same time each day.

  • Treatment Duration: Continue taking the medicine as prescribed until your doctor advises otherwise or until disease progression occurs.

Never change your dose without consulting your healthcare provider.

Possible Side Effects

Like all cancer medicines, Qinlock may cause side effects. Not every patient experiences them, but common ones include:

  • Fatigue or tiredness

  • Nausea and vomiting

  • Loss of appetite

  • Hair thinning or hair loss

  • Muscle pain or joint discomfort

  • Hand-foot skin reactions (redness, swelling, or peeling on palms and soles)

Serious but less common effects may include:

  • High blood pressure

  • Skin changes or new growths

  • Wound healing problems

  • Risk of sun sensitivity

Regular medical monitoring helps in detecting and managing these effects early.

Safety Precautions

  • Pregnancy and Breastfeeding: Qinlock should not be used during pregnancy or breastfeeding due to potential risks.

  • Skin Protection: Use sunscreen and protective clothing as the medicine can make skin more sensitive to sunlight.

  • Surgery Considerations: Qinlock may affect wound healing; your doctor may pause treatment before and after surgery.

  • Monitoring: Routine blood tests, skin checks, and blood pressure monitoring are recommended during therapy.
