A new Danish study suggests that the practice of draining off lung fluid to avoid pemetrexed (Alimta) toxicity may not be necessary for all patients. Surviving Mesothelioma has just posted details of the new study for mesothelioma patients and their families. Click here to read it now.
Researchers at the University of Copenhagen tested the concentration of the popular mesothelioma drug, pemetrexed, in the pleural fluid and plasma of eight lung cancer patients. They found that, unlike the similar drug methotrexate, pemetrexed does not tend to stay in the pleura.
“Pemetrexed is not likely to accumulate in the pleural fluid and evacuation of fluid might not be necessary,” writes lead investigator Per Hartvig Honoré, a Professor of Pharmacokinetics at the University of Copenhagen.
The new study in Cancer Chemotherapy and Pharmacology points out that, although little research has been done on accumulation of pemetrexed in third-space fluid, the fluid draining recommendations were the same because pemetrexed is an analog of methotrexate.
“If this research leads to a change in the recommendation, it is potentially good news for mesothelioma patients since fluid evacuation can be painful and can raise the risk of infection,” says Surviving Mesothelioma’s Managing Editor, Alex Strauss.
