DePuy hip replacement recall

In August 2010, DePuy recalled its hip replacement systems ASR XL Acetabular Hip Replacement System and ASR Hip Resurfacing System due to failure rates and side effects including metallosis. The recalls triggered a large number of lawsuits against DePuy and its parent company Johnson & Johnson upon claims that the companies knew about the dangers of the implants before they went on the market in the United States. == References ==
As the drug is partly metabolised via the liver enzyme CYP3A4, strong inducers of this enzyme can decrease its blood plasma concentrations. CYP3A4 inhibitors do not significantly increase vandetanib concentrations, presumably because it is also metabolised by flavin containing monooxygenase 1 (FMO1) and 3. Pharmacology
Vandetanib is an inhibitor of vascular endothelial growth factor receptor-2, epidermal growth factor receptor, and RET tyrosine kinases. RET tyrosine kinases; it weakly inhibits VEGFR-3. Vandetanib is well absorbed from the gut, reaches peak blood plasma concentrations 4 to 10 hours after application, and has a half-life of 19 days on average, per pharmacokinetic studies. It has to be taken for about three months to achieve a steady-state concentration. In the blood, it is almost completely (90–96%) bound to plasma proteins such as albumin. It is metabolised to N-desmethylvandetanib via CYP3A4 and to vandetanib-N-oxide via FMO1 and 3. Both of these are active metabolites. Vandetanib is excreted via the faeces (44%) and the urine (25%) in form of the unchanged drug and the metabolites. History
Vandetanib was approved by the FDA in April 2011, for treatment of late-stage thyroid cancer.Vandetanib was first initially marketed without a trade name; it has been marketed under the trade name Caprelsa since August 2011.In 2015 Genzyme acquired the product from AstraZeneca. Research
AstraZeneca tested Vandetanib in clinical trials for non-small cell lung cancer and submitted an application for approval to the EMA but then withdrew the application in October 2009 after trials showed no benefit when the drug was administered alongside chemotherapy.
