    Blood Pressure Drugs and Lip Cancer: A Link?

    Certain Hypertension Medicines May Boost Risk of Lip Cancer: Study

    Aug. 7, 2012 -- Some high blood pressure medicines, when taken long term, may increase the risk of lip cancer in white people, according to new research.

    The list includes commonly used drugs such as the diuretic hydrochlorothiazide (HydroDIURIL, Microzide, others) and the ACE inhibitor lisinopril (Prinivil, Zestril).

    The finding, however, is buffered with some reassurance. "I want to emphasize that lip cancer is rare," says Gary D. Friedman, MD, an emeritus researcher and former director of the Kaiser Permanente Northern California Division of Research. He led the study.

    Lip cancer rarely spreads, he says. It is usually recognized early and treated promptly.

    "I do not want to alarm people to the extent they are going to stop taking their medicine for blood pressure," he says. The study findings are not a reason to stop any medicines that make people more sensitive to the sun, he says.

    The study is published online in the Archives of Internal Medicine.

    Every year in the U.S., about 35,000 people are diagnosed with oral cancers, including lip cancers, according to the National Cancer Institute.

    Blood Pressure Drugs & Lip Cancer: Study Details

    In a previous study, Friedman had noticed an increase in lip cancers among people on certain high blood pressure medicines.

    For this study, he evaluated the types of blood pressure prescriptions dispensed and lip cancers found in patients at Kaiser Permanente from 1994 until early 2008.

    He focused only on lip cancers, Friedman says, because data on skin cancers was not available.

    Friedman focused on five high blood pressure drugs or drug combinations that are commonly prescribed. Besides hydrochlorothiazide and lisinopril, they included:

    All but atenolol are known to make the skin more sun-sensitive.

    Blood Pressure Drugs & Lip Cancers: Results

    During the study, 712 patients on blood pressure drugs were diagnosed with lip cancer. The researchers compared them to nearly 23,000 others who did not have lip cancer.

    After finding a reduced risk of lip cancer among all minority groups, Friedman only evaluated white people.

    For those who took the drugs for five years or longer, the risk compared to those who didn't take blood pressure drugs varied by drug.

    • Those on hydrochlorothiazide had more than four times the risk.
    • Those on hydrochlorothiazide-triamterene had a nearly three times greater risk.
    • Those on nifedipine, 2.5 times higher risk.
    • Those on lisinopril, 1.4 times greater risk.
