0.00$

Larogen capsules hold 100mg of Larotrectinib, a targeted therapy employed in oncology to treat solid tumors possessing neurotrophic receptor tyrosine kinase (NTRK) gene fusions. Acting as a tyrosine kinase inhibitor, Larotrectinib blocks particular enzymes engaged in the growth and multiplication of cancer cells. Healthcare providers prescribe Larogen capsules as a component of the treatment plan for suitable patients diagnosed with these precise tumor types.

    Larotrectinib 100mg is a prescribed drug designed for treating both adult and pediatric patients with solid tumors that exhibit neurotrophic receptor tyrosine kinase (NTRK) gene fusions. These fusions are genetic anomalies that aid in the growth and survival of specific cancer cell types. Larotrectinib is a member of the selective TRK inhibitors class, providing a highly focused strategy for cancer treatment.

     

    Larotrectinib serves as a generic version of Larotrectinib, an innovative cancer treatment initially branded as Vitrakvi. It holds particular significance for patients lacking satisfactory alternative treatment options or those who have developed resistance to standard therapies.


    Mechanism of Action

    Larotrectinib serves as a highly selective inhibitor of TRK (tropomyosin receptor kinases) proteins, which are encoded by the NTRK1, NTRK2, and NTRK3 genes. When these genes fuse abnormally with other genes, TRK fusion proteins are produced that drive tumor growth. Larotrectinib binds to these proteins, blocking signals that encourage the proliferation and survival of tumor cells, thus effectively stopping disease progression in tumors reliant on this pathway.

     

    Larotrectinib is thus classified as a precision oncology drug: it is intended to be effective solely against cancers with NTRK gene fusions, irrespective of tumor type or site.


    Indications and Usage

    Larotrectinib is recommended for treating:

     

    Solid tumors featuring NTRK gene fusions and lacking a known acquired resistance mutation

     

    Tumors that are metastatic or for which surgical resection is likely to cause significant morbidity

     

    Cases lacking satisfactory alternative treatment options

     

    Larotrectinib has demonstrated effectiveness across a wide range of cancers, including:

     

    Thyroid carcinoma

     

    NSCLC (non-small cell lung cancer)

     

    Pediatric tumors like infantile fibrosarcoma

     

    Neoplasms of the salivary glands

     

    Soft-tissue sarcomas


    Dosage and Administration

    Depending on the patient’s weight and clinical condition, the recommended dosage of Larotrectinib is as follows:

     

    Adults and children with a weight of ≥20 kg: 100 mg taken orally two times a day

     

    Children with a weight of <20 kg: 100 mg/m² by mouth, two times a day

     

    Capsules must be swallowed whole rather than chewed or crushed. It is possible to take Larotrectinib with or without meals. Treatment should persist until disease progression or intolerable toxicity occurs.

     

    Note: Always adhere to the prescribing physician’s specific dosage instructions.


    Side Effects

    As with all drugs, Larotrectinib can lead to side effects, but not everyone will encounter them. Among the side effects reported, the most common include:

     

    Müdigkeit

     

    Unsteadiness

     

    Vomiting and nausea

     

    Either constipation or diarrhea

     

    Liver enzymes are at elevated levels

     

    cough

     

    Increase in weight

     

    Eisenmangel

     

    Rare but serious side effects may include:

     

    Neurological symptoms like disorientation or trouble walking

     

    Hepatotoxizität

     

    QT prolongation (alterations in heart rhythm)

     

    Patients must receive regular monitoring throughout treatment, particularly liver function tests and electrocardiograms when needed.


    Warnings and Precautions

    Pregnancy and Breastfeeding: Larotrectinib may be detrimental to a developing fetus. It is not advised for use during pregnancy and breastfeeding. During treatment and for a minimum of 1 week following the last dose, effective contraceptive measures should be employed.

     

    Pediatric Use: Proven to be safe and effective for pediatric patients; the dose should be adjusted according to the body surface area.

     

    Interactions with drugs: There is a possibility of interaction with CYP3A4 inducers or inhibitors. Let your doctor know about all the medications you are currently using.


    Storage

    Keep at room temperature (15°C to 30°C)

     

    Avoid moisture and direct sunlight

     

    Ensure children cannot reach it.


    Availability and Pricing

    In certain countries, Larotrectinib can be obtained as a more affordable option compared to the branded variant. The cost may differ based on the manufacturer, area, and supply chain.

     

    This drug should be bought solely with a legitimate prescription and from authorized pharmacies or medical suppliers.


    Conclusion

    Larotrectinib marks a major progress in precision medicine, providing a targeted therapeutic choice for individuals with NTRK fusion-positive cancers. Larotrectinib offers new hope for patients with rare and hard-to-treat cancers, thanks to its tumor-agnostic strategy and manageable side effects. Always seek advice from your oncologist or healthcare provider to assess whether Larotrectinib is an appropriate treatment choice for you or your loved one.

    1. What is Larotrectinib 100 mg used for?
    Larotrectinib contains Larotrectinib, which is used to treat solid tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion. It is a targeted therapy designed for patients whose cancer cannot be surgically removed or has spread to other parts of the body.

     

    2. What is the mechanism of action of Larotrectinib?
    Larotrectinib functions by blocking the action of TRK fusion proteins generated from NTRK gene fusions. These proteins stimulate the growth of cancer cells. By blocking them, one can halt or reduce the advancement of cancer.

     

    3. Does Larotrectinib have FDA approval?
    The U.S. FDA approved Larotrectinib for treating NTRK fusion-positive tumors, irrespective of their location in the body, thereby making it one of the pioneering “tissue-agnostic” cancer therapies.

     

    4. What is the method of taking Larotrectinib?
    Larotrectinib 100 mg is an oral medication that is typically taken twice daily (every 12 hours), regardless of meals. Always adhere to your oncologist’s instructions concerning dosage and duration.

     

    5. Is Larotrectinib suitable for children?
    Larotrectinib is authorized for use in both adults and children with tumors that are positive for NTRK fusions. The dosage for children is determined according to their body surface area (BSA) and requires calculation by a healthcare professional.
