Study: Benefits of Some Cancer Drugs Mitigated by Other Drugs
Posted 16 March 2012 | By
Many cancer patients taking oncology drugs might see the beneficial effects of their medication fail to materialize if they are taking other medications, says a new study by Medco Health Solutions Inc.
The Medco study found between 23% and 57% of patients taking cancer drugs for a specific cancer were also taking medications that could alter the effects of the drug, including decreased effectiveness and increased toxicity.
"For Gleevec, 43% of the 4,617 cancer patients taking the therapy got medicines that may reduce its effectiveness, while 68% received drugs that might increase toxicity, reports Bloomberg.
The report highlights the importance of having primary care doctors and cancer specialists coordinate treatments with one another. "[T]he vast majority of the cancer drugs were prescribed by an oncologist, while the other medicines were typically prescribed by a primary care physician," said Reuters.
