Votrient 200mg
Votrient 200 mg is a type of protein kinase inhibitors, the main ingredient which is used as pazopanib . It is also indicated for the treatment of advanced kidney cancer and soft tissue sarcoma Votrient 200MG is an antineoplastics medications which interfere with the development and spreadness of cancer cells in the body.
USAGE
Votrient 200MG is used as a single agent to treat the renel cell carcinoma and its advanced stage It works by preventing the activity of proteins which are interferes with the growth and spread of cancer cells. Votrient 200mg is also used as a single regimen to treat the Soft Tissue Sarcoma, (a type of cancer that occurs in the supportive tissue of the body). The cancer can develop in muscles, blood vessels, fat tissue or in other tissues that support, surround and protect organs
PHARMACOLOGY
Votrient 200mg belongs to an inhibitor of potent protein kinase and selective multiple receptor tyrosine kinases (RTKs) which are described in beginning of signal transduction pathways that ready for proliferation of tumor cells and affect growth critical to cell continuity and tumor progression. RTKs comes in the blockage and involves the receptors for vascular endothelial growth factors (VEGFR-1, -2, and -3), platelet-derived growth factors (PDGFR-α and -β), and stem cell factor.
DOSAGE
Votrient dosage for renal cell carcinoma and soft tissue sarcoma (cancer in joints, muscle) will be initially 800mg , the dose adjustment in 200mg increments or decrements dose based on tolerance but max dose in adult is 800mg/day. Moderate total bilirubin >1.5 to 3 times, Votrient dose of 200mg once daily. Votrient should be taken on a empty stomach (1hr before or 2hr after meals. Swallow the medicine whole don’t chew/crush. Food interaction :Avoid grapefruit juice or grapefruit juice.

DRUG INTERACTION
Strong CYP3A4 enzyme inhibitors (e.g. ketoconazole, itraconazole, voriconazole,etc) + Votrient 200mg → Increase plasma concentration. Votrient + simvastatin → increases incidence of ALT elevation Votrient 200mg + PPI e.g. esomeprazole → decreases bioavailability. Concurrent use of strong of BCRP inhibitors or P-gp (e.g. lapatinib) and inducers + Votrient 200mg →alter the exposure and distribution of pazopanib. Votrient 200mg + rifampin(strong CYP3A4 Enzyme inducers) →decreases the plasma concentration.
