High blood pressure is one of the most common long-term health problems in older adults.
It forces the heart to work harder and slowly damages blood vessels throughout the body.
Over time, uncontrolled blood pressure can greatly increase the risk of heart attack, stroke, heart failure, kidney disease, and other serious health problems.
Many older people need more than one medicine to keep their blood pressure under control.
While these medicines are very effective, taking several tablets every day can sometimes cause dizziness, tiredness, falls, or unwanted interactions with other medicines.
This is especially important for people in their 80s and beyond, who are often taking medicines for several different health conditions.
Researchers from the University of Oxford wanted to find out whether some older adults could safely reduce the number of blood pressure medicines they take. Their goal was to see if carefully removing one medicine would still keep blood pressure at a safe level while reducing the chance of medication-related problems.
The study included 569 adults aged 80 years and older who were already receiving treatment for high blood pressure. On average, each participant was taking two blood pressure medicines before the study began.
The participants were randomly divided into two groups. One group continued taking all of their usual medicines, while the other group stopped taking one blood pressure medicine under medical supervision. The researchers then closely monitored both groups for 12 weeks.
At the end of the study, the results were encouraging. Around 87 percent of people in both groups still had a systolic blood pressure below 150 mm Hg, a target that is often considered suitable for many older adults. This showed that most people who reduced their medicines continued to keep their blood pressure under good control.
People who stopped one medicine had an average systolic blood pressure that was only 3.4 mm Hg higher than those who continued all of their medicines. The researchers considered this difference to be small and unlikely to cause major health concerns during the short study period.
Serious health problems were uncommon in both groups. Twelve people in the reduced-medication group experienced a serious event compared with seven people in the group that continued normal treatment. Overall, the study did not find evidence that carefully reducing medication caused a large increase in short-term risk.
Another important finding was that about two out of every three people who stopped one medicine were still successfully managing their blood pressure after 12 weeks without needing to restart the treatment.
The researchers believe these findings may help doctors and patients have better conversations about medication. Some older adults whose blood pressure has been stable for a long time may not always need the same number of medicines they once required. However, every patient is different, and decisions should always be made individually.
The study does not suggest that people should stop taking blood pressure medicines on their own. Suddenly stopping treatment can be dangerous. Any changes should only be made after discussing them with a doctor, who can monitor blood pressure and make sure it remains within a safe range.
This research offers hope that some older adults may be able to simplify their treatment without losing the protection that blood pressure medicines provide. Fewer medicines could also mean fewer side effects and an improved quality of life for carefully selected patients.
