Pezinib 400mg Tablet (Pazopanib) – Uses, Side Effects, Dosage & Price in Pakistan

Pezinib 400mg Tablet (Pazopanib) is an oral targeted cancer medicine belonging to the kinase inhibitor group. It is used in adults with certain advanced cancers, particularly advanced renal cell carcinoma (RCC) and advanced soft tissue sarcoma (STS) in patients who have already received chemotherapy. Pazopanib works by blocking specific kinase pathways involved in tumor growth and the formation of blood vessels that can supply a tumor.

For patients in Pakistan looking for reliable information about Pezinib 400mg Tablet (Pazopanib), it is important to understand its approved uses, dosage, possible side effects, precautions, and medicine interactions. Impo Medic provides medicine-related information to help patients and caregivers understand prescription medicines before discussing treatment with their healthcare professional.

Pezinib 400mg Tablet (Pazopanib) Used For

Pezinib 400mg Tablet (Pazopanib) may be prescribed for adults with:

• Advanced renal cell carcinoma (RCC)
• Advanced soft tissue sarcoma (STS) after prior chemotherapy

The approved information does not establish efficacy for adipocytic soft tissue sarcoma or gastrointestinal stromal tumors. Treatment should therefore be based on the patient’s diagnosis and the oncologist’s treatment plan.

Renal Cell Carcinoma

Renal cell carcinoma is a type of kidney cancer. In advanced disease, targeted medicines such as pazopanib may be used to interfere with signaling pathways that support cancer-cell growth and tumor blood-vessel formation.

Pezinib 400mg Tablet should only be used for this purpose when prescribed by a qualified healthcare professional after considering the patient’s cancer type, previous treatments, medical history, and laboratory results.

Soft Tissue Sarcoma

Pazopanib is also indicated for adults with advanced soft tissue sarcoma who have received prior chemotherapy. Soft tissue sarcomas develop in tissues such as muscle, fat, connective tissue, blood vessels, or other supporting tissues.

The suitability of treatment depends on the specific sarcoma subtype and the patient’s previous treatment history.

How Pezinib 400mg Tablet (Pazopanib) Works

Pazopanib is a kinase inhibitor. It interferes with signaling proteins involved in cancer growth and angiogenesis, the process through which new blood vessels form.

By inhibiting relevant pathways, pazopanib can reduce signals that help tumors grow and develop their blood supply. This mechanism makes it different from traditional cytotoxic chemotherapy, although it can still cause significant adverse effects and requires medical monitoring.

Pezinib 400mg Tablet is therefore considered a targeted therapy rather than a conventional chemotherapy medicine.

Pezinib 400mg Tablet Dosage

The labeled recommended dose of pazopanib is 800 mg once daily, taken without food, at least 1 hour before or 2 hours after a meal. Tablets should be swallowed whole and should not be crushed.

Because Pezinib 400mg Tablet contains 400 mg of pazopanib, the number of tablets required for an individual treatment regimen must be determined by the prescribing oncologist. Patients should not independently change the number of tablets.

Dose adjustments may be necessary because of:

• Liver impairment
• Treatment-related adverse reactions
• Certain drug interactions
• Individual tolerance and clinical response

For moderate hepatic impairment, current prescribing information recommends a reduced dose of 200 mg once daily. Pazopanib is not recommended in severe hepatic impairment in the cited prescribing information.

If a dose is missed and less than 12 hours remain before the next scheduled dose, the missed dose should not be taken.

How to Take Pezinib 400mg Tablet

Take Pezinib exactly as prescribed by your oncologist.

Important administration points include:

• Take it on an empty stomach.
• Take it at approximately the same time each day.
• Take it at least 1 hour before or 2 hours after food.
• Swallow the tablet whole.
• Do not crush or chew the tablet.
• Do not change the dose without medical advice.

Taking pazopanib with food can affect its absorption, so following the prescribed timing in relation to meals is important.

Pezinib 400mg Tablet Side Effects

Like other targeted cancer medicines, Pezinib 400mg Tablet can cause side effects. Their severity can vary between patients.

Commonly reported adverse effects of pazopanib may include:

• Diarrhea
• Nausea
• Vomiting
• Loss of appetite
• Changes in taste

Not every patient experiences all of these effects.

Patients should tell their healthcare provider if side effects become persistent, severe, or interfere with normal daily activities.

Serious Side Effects and Warnings

Pazopanib carries an important warning for severe and potentially fatal liver toxicity. Liver-function tests should be performed before and during treatment as directed by the healthcare professional.

Contact a healthcare professional promptly if symptoms such as yellowing of the skin or eyes, dark urine, unusual tiredness, loss of appetite, abdominal discomfort, or unusual bruising occur.

Other important risks associated with pazopanib include:

• High blood pressure
• QT interval prolongation and serious heart-rhythm problems
• Cardiac dysfunction
• Bleeding
• Blood-clotting events
• Gastrointestinal perforation or fistula
• Wound-healing complications
• Protein in the urine

• Reversible posterior leukoencephalopathy syndrome in rare cases

Patients may require blood pressure checks, liver tests, urine tests, ECG monitoring, or other assessments depending on their clinical situation.

Precautions Before Using Pezinib 400mg Tablet

Tell your doctor about all existing medical conditions before starting treatment.

Extra caution may be needed in patients with:

• Liver disease

• Heart disease
• Abnormal heart rhythm
• Previous blood-clotting problems
• Bleeding disorders
• Recent surgery

Inform your healthcare provider about every medicine, vitamin, supplement, or herbal product you use. Some medicines can change pazopanib levels or increase the risk of adverse effects.

Pezinib 400mg Tablet Drug Interactions

Pazopanib can interact with other medicines. Strong CYP3A4 inhibitors may increase pazopanib concentrations, while strong CYP3A4 inducers may decrease its concentrations. The prescribing information recommends avoiding certain strong CYP3A4 inhibitors or using appropriate dose modifications when necessary. Strong CYP3A4 inducers should generally be avoided.

Patients should not start or stop prescription medicines, over-the-counter products, vitamins, or herbal supplements without discussing them with their healthcare provider.

Pezinib 400mg Tablet During Pregnancy

Pazopanib may cause fetal harm based on its mechanism and available animal data. Women who are pregnant or may become pregnant should discuss the risks with their healthcare provider before treatment.

Patients should follow their oncology team’s advice regarding contraception and pregnancy prevention during treatment and for the recommended period after treatment.

Breastfeeding should also be discussed with a healthcare professional before starting therapy.
