Description
Lenvat 4 mg Capsule is a prescription cancer medicine made by Natco Pharma Ltd. It contains the active ingredient lenvatinib, which belongs to a targeted treatment group called tyrosine kinase inhibitors (TKIs). Lenvatinib 4 mg Capsule treats thyroid, kidney, and liver cancer. Lenvatinib blocks specific proteins: VEGFR1, VEGFR2, VEGFR3, FGFR1, FGFR2, FGFR3, FGFR4, PDGFRα, RET, and KIT, which help cancer cells grow and make new blood vessels. Cancer cells use blood vessels to get food and oxygen. By stopping this process, Lenvat 4 mg slows or stops cancer growth, and may even help reduce tumor size. This medicine is only available with a doctor's prescription and should be taken exactly as your healthcare provider advises to ensure safety and effectiveness.
Benefits
- Directly targets cancer growth: Lenvatinib is a targeted therapy that blocks multiple proteins (like VEGFR, FGFR, PDGFR, RET, and KIT) that help tumors grow, multiply, and spread.
- Slows cancer progression: It helps slow down or stop the growth of cancer cells in patients with thyroid, kidney, and liver cancers, especially in cases where other treatments haven’t worked.
- Shrinks tumors: Lenvatinib 4 mg can reduce tumor size by blocking the cancer’s blood supply (angiogenesis), making cancer more manageable.
- Effective in advanced cancers: It is especially useful in advanced (Stage III) or metastatic cancers, where the disease has spread to other parts of the body or cannot be removed by surgery.
- Oral administration: Lenvat 4 mg is taken by mouth, making it a convenient, non-invasive option compared to injectable therapies.
- Used with other therapies: It may be combined with other medicines like everolimus for better treatment outcomes for kidney cancer.
Improved quality of life: In clinical trials, many patients showed slower disease progression, allowing for better daily functioning and longer survival times in some cancer types.
Indications and Usage
Lenvat 4 mg Capsule (lenvatinib) treats thyroid, kidney, and liver cancer by slowing the growth and spread of tumor cells. It is a targeted therapy prescribed by doctors when other treatments, like radioactive iodine therapy or prior anti-angiogenic therapy, may not be effective or suitable.
Approved Uses:
-
- Thyroid Cancer: For adults with radioactive iodine-refractory differentiated thyroid cancer (DTC)—a cancer that no longer responds to radioactive iodine therapy.
- Kidney Cancer: For patients with advanced renal cell carcinoma (RCC):
- As a first-line treatment when combined with pembrolizumab
- Used in combination with everolimus after progression on prior anti-angiogenic therapies, such as:
- Sunitinib (Sutent)
- Pazopanib (Votrient)
- Axitinib (Inlyta)
- Bevacizumab (Avastin)
- Temsirolimus (Torisel)
- Sorafenib (Nexavar)
- Liver Cancer
For adults with unresectable hepatocellular carcinoma (HCC), liver cancer that cannot be removed with surgery. - Endometrial Cancer (in combination: Lenvatinib + Pembrolizumab )
For advanced endometrial carcinoma that has progressed after previous treatments, when used with pembrolizumab
Major global health agencies, including the U.S. FDA and EMA, approve these uses.
How it Works
Lenvat 4 mg Capsule contains lenvatinib, a potent anti-cancer drug known as a tyrosine kinase inhibitor (TKI). Tyrosine kinases are special enzymes (proteins) found in the body that play a key role in how cells grow, divide, and form new blood vessels.
Why Cancer Cells Need These Proteins:
Cancer cells grow and survive by sending signals through tyrosine kinases, which tell them to:
- Grow rapidly and uncontrollably
- Spread to other parts of the body (metastasis)
- Create new blood vessels (angiogenesis) to bring oxygen and nutrients to the tumor
This helps tumors stay alive, grow bigger, and spread quickly.
What 4 mg Lenvatinib Targets
Lenvatinib works by blocking multiple receptors that are often overactive in cancer cells, such as:
- VEGFR (Vascular Endothelial Growth Factor Receptor) – helps form new blood vessels
- FGFR (Fibroblast Growth Factor Receptor) – supports tumor growth and survival
- PDGFR (Platelet-Derived Growth Factor Receptor) – involved in blood vessel formation and tissue repair
- RET and KIT – mutated or overactive in several types of tumors
By blocking these receptors, lenvatinib disrupts the signals that cancer cells rely on to grow and survive.
What Happens When Lenvatinib Starts Working
When Lenvat 4 mg begins to take effect, it can help limit the cancer’s ability to grow and spread.
Here’s how it may help:
- Slows or stops tumor growth: Cancer cells stop receiving the signals they need to grow and multiply.
- Reduces blood supply to tumors: By blocking the formation of new blood vessels, tumors are deprived of oxygen and nutrients.
- Weakens cancer cells: Without enough support, cancer cells may become fragile and begin to die over time.
May shrink tumors or stop them from spreading: Some tumors may reduce in size, or at least stop moving to other parts of the body.
Dosage & Administration
Recommended Dosage for Lenvatinib 4 mg:
The appropriate dosage of Lenvatinib varies depending on the type of cancer being treated, the patient’s body weight, and overall health. A healthcare provider will determine the most suitable dose for each individual.
Typical dosing guidelines include:
- Differentiated Thyroid Cancer (DTC): 24 mg taken orally once daily.
- Advanced Renal Cell Carcinoma (RCC):
- First-line treatment (with pembrolizumab): 20 mg taken orally once daily.
- Previously treated (with everolimus): 18 mg taken orally once daily.
- Hepatocellular Carcinoma (HCC):
- Patients weighing ≥60 kg: 12 mg taken orally once daily.
- Patients weighing <60 kg: 8 mg taken orally once daily.
- Advanced Endometrial Carcinoma (with pembrolizumab): 20 mg taken orally once daily.
Dosage adjustments may be necessary based on individual tolerance and the presence of side effects. It’s crucial to follow the prescribing doctor’s instructions and not to alter the dosage without medical consultation.
How to Take Lenvatinib 4 mg
Taking the Medication:
- Swallow whole: Take the capsule with a full glass of water. Do not crush, chew, or open it.

Missed Dose:
- If you forget a dose: Take it as soon as you remember. However, if it’s nearly time for your next dose, skip the missed one. Do not double up to make up for a missed dose.
Overdose Warning:
- Seek immediate help: Taking too much Lenvatinib can lead to serious health issues, including high blood pressure, liver problems, or severe bleeding. If you suspect an overdose, contact your doctor or go to the nearest hospital right away.
Always consult your healthcare provider for personalized guidance.
