[Antihypertensive drugs and malignant neoplasia].

Analysis of epidemiological, cohort and randomized studies of antihypertensive drugs containing reports of development of malignant neoplasms shows that long term use of some antihypertensive drugs while preventing cardiovascular complications has been associated with increased risk of malignancies. Most convincing evidence exists for association between the use of diuretics and renal cancer. Association between the use of reserpine and breast cancer in women, between atenolol and some types of cancer in elderly men also can not be ruled out. There is no proof of existence of either negative or positive correlation between malignant neoplasia and long-term use of calcium antagonists, angiotensin converting enzyme inhibitors or angiotensin receptor blockers.
