Pazokast 400mg Tablet (Pazopanib)

Pazokast 400mg Tablet contains pazopanib, an oral multi-target tyrosine kinase inhibitor that blocks signaling through vascular endothelial growth factor receptors (VEGFRs), platelet-derived growth factor receptors, and other kinases involved in tumor growth and blood-vessel formation.

It is used in selected patients with advanced renal cell carcinoma and certain advanced soft-tissue sarcomas. Because pazopanib 400mg can affect the liver, blood pressure, heart, thyroid, and gastrointestinal tract, treatment requires regular monitoring. Pazokast 400mg Tablet is a prescription medicine and should be taken exactly as directed by an oncologist. Food can substantially increase pazopanib 400mg tablet exposure, so administration timing in relation to meals is important.

Pazopanib 400mg tablet is approved for adults with advanced renal cell carcinoma in appropriate treatment settings and for selected patients with advanced soft-tissue sarcoma who have received prior chemotherapy, subject to tumor subtype and local label. It is not effective for every soft-tissue sarcoma subtype and is generally not used for adipocytic sarcoma under major regulatory labels. Treatment with Pazopanib 400mg tablets selection considers histology, previous therapy, liver function, cardiovascular risk, blood pressure, and potential interactions. The medicine may be continued while disease control is maintained and toxicity remains manageable.

Pazopanib tablets are oral multi-target tyrosine kinase inhibitors that block VEGFR-1, VEGFR-2, VEGFR-3, PDGFR, and other kinases. These pathways help tumors form new blood vessels and support growth. Inhibition can reduce angiogenesis and tumor-cell signaling. Because VEGF signaling is also important in normal vascular function, the same mechanism contributes to hypertension, proteinuria, bleeding, wound-healing problems, and cardiovascular toxicity.

Evidence context: The studies below are pivotal or widely cited evidence supporting the pazopanib 400mg tablet in major treatment settings. Trial results should not be interpreted as a guarantee of benefit for an individual patient, and exact eligibility must match the current approved indication and oncology guideline.

Pazokast 400mg Tablet may cause side effects, and their frequency varies by indication, dose, combination regimen, and patient population. The list below highlights clinically important effects rather than assigning a single percentage across different trials.

Common side effects

• Diarrhea
  
• Hypertension
  
• Hair color changes
  
• Nausea
  
• Reduced appetite
  
• Fatigue
  
• Taste changes
  
• Weight loss
  

Serious side effects 

• Severe liver injury
  
• Severe hypertension
  
• QT prolongation / cardiac dysfunction
  
• Bleeding or thromboembolism
  
• GI perforation / fistula
  
• PRES

The usual labelled adult dose is 800 mg orally once daily on an empty stomach, at least 1 hour before or 2 hours after food. Swallow tablets whole; crushing can increase absorption. Dose modification is required for toxicity and selected hepatic impairment. Avoid strong CYP3A inhibitors/inducers where possible. The Pazokast 400 mg tablet strength commonly means two tablets are required for an 800 mg dose unless the oncologist prescribes a reduced dose.

Administration guidance: Take the Pazokast 400mg Tablet exactly as prescribed, usually once daily on an empty stomach, at least 1 hour before or 2 hours after food. Swallow the tablet whole; do not crush it because this can change absorption. Take it at approximately the same time each day. Avoid grapefruit products. Liver-function tests and blood pressure should be checked regularly, particularly early in treatment. Thyroid, urine protein, and cardiac monitoring may also be required. Acid-reducing medicines can reduce pazopanib tablet absorption, so discuss PPIs, H2 blockers, and antacids with your oncologist. Dose interruption or reduction may be required for toxicity.

If the next dose is due within 12 hours, skip the missed dose. Do not take two doses together. Do not repeat a dose after vomiting.

Check liver tests before treatment and frequently during the first months according to the label. Control blood pressure before treatment and monitor regularly. Assess ECG/electrolytes in patients at risk for QT prolongation. Monitor urine protein, thyroid function, and cardiac status as clinically indicated.

Practical monitoring checklist

• Blood pressure before treatment and regularly during therapy
  
• Liver function according to baseline risk and treatment label
  
• Renal function and hydration/renal toxicity assessment as clinically indicated
  
• Cardiac assessment/ECG or ejection-fraction monitoring when clinically indicated
