Gefitinib Pharmaceutical Raw Material Powder Cas 184475-35-2 Anti Tumor

Gefitinib Description

Gefitinib (ZD1839) (INN, , trade name Iressa, marketed by AstraZeneca and Teva), is a drug used for certain breast, lung and other cancers. Gefitinib is an EGFR inhibitor, like erlotinib, which interrupts signaling through the epidermal growth factor receptor (EGFR) in target cells. Therefore, it is only effective in cancers with mutated and overactive EGFR. However, meta-analyses have not shown any improvement in overall survival, that is, it does not extend life.

Gefitinib is used to treat non-small cell lung cancer that has spread to other parts of the body in people with certain types of tumors. Gefitinib is in a class of medications called kinase inhibitors. It works by blocking the action of a certain naturally occurring substance that may be needed to help cancer cells multiply.

How to use Gefitinib

Gefitinib comes as a tablet to take by mouth. It is usually taken with or without food once a day. Take gefitinib at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take gefitinib exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

If you are unable to swallow the tablets, you may dissolve them in water. Place one tablet in 4 to 8 ounces (120 to 240 mL) of plain, noncarbonated drinking water. Stir with a spoon for about 15 minutes until the tablet is dissolved. Drink the mixture right away. Rinse the glass with another 4 to 8 ounces (120 to 240 mL) of water and drink the rinse water right away to be sure that you swallow all of the medication.

Your doctor may delay or permanently stop your treatment if you experience certain side effects. Be sure to tell your doctor how you are feeling during your treatment with gefitinib.
