Article Synopsis
  • A study was conducted to see if switching from taking rosuvastatin and ezetimibe as separate pills to a single pill improves adherence to the medication among patients in Italy.
  • The analysis focused on nearly 1220 patients, mostly older adults with cardiovascular issues, and found that those using the single-pill combination were more likely to consistently take their medication compared to those using the separate pills.
  • The results indicate that reducing the number of pills patients need to take can significantly improve their adherence to cardiovascular drug therapy.

Atherosclerotic cardiovascular diseases remain the main cause of mortality worldwide, due to a poor control of modifiable risk factors for atherosclerosis. High levels of low-density lipoprotein cholesterol represent the most relevant actor in the development of atherosclerotic cardiovascular diseases, as well as the main target of prevention strategies. Although lipid-lowering treatments were shown to be effective for cardiovascular prevention, several barriers (e.
