Midazolam is a medication often given to help people feel sleepy and less anxious before surgery.
It’s commonly used because it can make patients feel more relaxed, and they usually don’t remember much about the procedure afterward. This helps in reducing stress and anxiety for the patient.
However, a recent study by researchers from the University of Colorado Anschutz Medical Campus has found that the timing of midazolam administration could have surprising effects on heart health.
Specifically, it seems that giving this drug at night during surgery may increase the risk of heart injury. This discovery highlights how important it can be to consider not just what drugs are used, but when they are used.
The researchers analyzed a massive amount of medical data to come to this conclusion. They looked at over 1.7 million cases where midazolam was given to more than 950,000 patients.
Out of these cases, they focused on just over 16,000 people who had suffered from heart damage, known as myocardial injury, after surgery.
While the overall analysis didn’t show a clear connection between midazolam use and heart problems, the researchers found something interesting when they looked more closely at the time the drug was given.
When surgeries took place at night, the risk of heart injury appeared to increase, especially in healthier patients undergoing non-cardiac surgeries.
This finding is important because it suggests that the time of day can affect how certain drugs work. In this case, midazolam may be riskier for the heart if given at night, even though it’s generally considered a safe sedative.
This could potentially affect many people, as midazolam is widely used in hospitals and clinics for surgeries.
The reason why midazolam may cause more problems at night isn’t fully understood yet.
However, the researchers suspect it might have to do with how our bodies follow a natural 24-hour rhythm, known as the circadian rhythm. This internal clock helps regulate many important functions in the body, including the heart.
A particular protein in the body called PER2 plays a role in protecting the heart from damage. This protein is influenced by light and is more active at night.
The study found that midazolam might interfere with the normal activity of PER2, particularly at night, making the heart more vulnerable to injury.
The drug works by increasing a chemical in the brain called GABA, which helps calm the brain and body. While this can reduce anxiety and stress, it might also lower the levels of PER2 at night, which could make the heart less protected during nighttime surgeries.
This could explain why the heart injury risk is higher when midazolam is used at night.
These findings are part of a growing body of research suggesting that the time of day when a drug is given can significantly affect how well it works and how safe it is.
For instance, other studies have shown that certain blood pressure medications work best when taken at night. It’s possible that midazolam and other drugs might also need to be timed carefully to avoid harmful side effects.
Given these results, the researchers recommend that future studies on drugs like midazolam should carefully consider what time of day the medication is most effective and safest. This could lead to better guidelines for doctors and safer outcomes for patients.
The study was conducted by Dr. Tobias Eckle and his team, and their findings were published in Frontiers of Cardiovascular Medicine.
The research is a reminder that even commonly used drugs like midazolam may have hidden risks that depend on when they are administered. For now, this discovery may help doctors make more informed choices when planning surgeries, especially those taking place at night.
