Certain blood pressure drugs may carry an increased risk of lung cancer, research has suggested.
Patients who took angiotensin-converting enzyme inhibitors (ACEIs) were up to 31 per cent more likely to develop the disease, according to a study.
Researchers at McGill University in Canada said that while the effects seemed modest, the drugs were so widely prescribed that “these small relative effects could translate into large absolute numbers of patients at risk”.
Researchers examined data on patients taking two different types of drug used to treat hypertension. They analysed the use of ACEIs compared with another group of blood pressure drugs called angiotensin receptor blockers (ARBs).
In the study, published in The BMJ, experts from Northern Ireland and Canada examined data on almost a million…
