What tests are done before lapatinib?
Before starting lapatinib, which is used primarily for certain types of breast cancer, several tests and evaluations are typically performed to ensure it's an appropriate treatment for the patient. These may include:
HER2 Status Test: lapatinib price philippines is often used for HER2-positive breast cancer. Tests like immunohistochemistry (IHC) or fluorescence in situ hybridization (FISH) are done on tumor tissue samples to confirm the presence of high levels of HER2 protein or HER2 gene amplification.
Liver Function Tests: Lapatinib is metabolized by the liver, so it's important to check liver function to ensure there are no underlying issues that might affect the drug's metabolism or increase the risk of side effects.
Cardiac Function Tests: Since lapatinib can potentially affect heart function, especially if used in combination with other drugs like trastuzumab, evaluating cardiac health through tests like an echocardiogram or a MUGA scan might be necessary.
Kidney Function Tests: While not as critical as liver function, assessing kidney function can help ensure that the kidneys are able to handle the drug and its metabolites.
General Health Evaluation: Overall health and any pre-existing conditions are assessed to determine if the patient is fit for treatment and to tailor the treatment plan to their specific needs.
These tests help healthcare providers determine the suitability of lapatinib price in india for the patient and to monitor for potential side effects throughout the treatment process.
