Cholesterol-lowering drugs: benefits and side effects

Cholesterol-lowering drugs are widely prescribed, especially as people get older, to protect against heart problems, high blood pressure, diabetes, and other age-related health issues.

These medications, while effective at managing cholesterol levels, have also been linked to some unexpected effects, both good and bad. A recent study led by Kitty Pham, a Ph.D. student at the University of South Australia, sheds light on these potential outcomes.

Types of Cholesterol-Lowering Drugs

The most common cholesterol-lowering drugs are statins, with well-known names like Lipitor and Crestor. Statins work by slowing the production of cholesterol in the body, helping to lower levels in the bloodstream.

Another, newer type of cholesterol drug is called PCSK9 inhibitors. These medications work differently by clearing cholesterol already stored in the body’s cells. While both types are effective at reducing cholesterol, they may also have unintended effects.

What Are the Possible Side Effects?

PCSK9 Inhibitors: Researchers have raised concerns about how these newer drugs might affect lung health. Although the long-term effects of PCSK9 inhibitors are not yet fully understood, early findings suggest they could lead to breathing problems for some people.

Statins: For statins, the side effects can be surprising. Some people taking these medications have been found to gain weight or body fat. There is also evidence that statins can lower testosterone levels, a hormone essential for maintaining energy, muscle strength, and overall health in both men and women.

However, statins may also have positive side effects. Researchers discovered that some people taking statins experienced an increase in the size of their hippocampus, a part of the brain responsible for memory and emotions. This finding is encouraging because it suggests that statins might reduce the risk of conditions like dementia and depression.

How Was the Research Conducted?

The study used genetic information to understand how these drugs affect people. By examining the “blueprint” of participants’ bodies through their DNA, researchers were able to predict potential side effects and benefits of the drugs without conducting lengthy and expensive clinical trials.

For example, they identified genetic markers that might make some individuals more prone to weight gain when taking statins. This method allows researchers to study long-term effects more efficiently and provides valuable insights into how different people may respond to the same medications.

What Do These Findings Mean for You?

If you’re taking cholesterol-lowering medication, it’s important to understand that these drugs are designed to help keep you healthy. However, like any medicine, they can come with side effects. The key is to work closely with your doctor, who can monitor your health and adjust your treatment plan if needed.

  • For Statin Users: If you notice weight gain or other changes in your body, don’t be alarmed. These could be side effects of the medication, but it’s always a good idea to discuss them with your doctor.
  • For PCSK9 Inhibitor Users: If you experience changes in your breathing, it’s important to let your doctor know, as it could indicate that the drug is affecting your lungs.

These findings do not mean you should stop taking your medication. Cholesterol-lowering drugs are an essential part of managing heart health for many people. Instead, this research helps improve our understanding of how these drugs work and ensures that doctors can make the best decisions for their patients.

The Bigger Picture

As scientists continue to study cholesterol-lowering medications, we’re learning more about their effects—both positive and negative. This information helps doctors tailor treatments to individual needs and allows patients to make informed decisions about their health.

The study was published in the British Journal of Clinical Pharmacology and is part of a growing body of research aimed at improving the safety and effectiveness of these important medicines. If you have questions or concerns about your cholesterol medication, talk to your doctor—they’re there to help you navigate the best options for your health.
