Insights

Bempedoic acid (BA) shows higher odds of muscle-related adverse drug reactions (ADRs) than atorvastatin (ATO), but these are generally less severe. Increased attention is needed for muscle symptoms with BA, especially when combined with statins.

Area of Science:

  • Cardiology
  • Pharmacology
  • Drug Safety

Background:

  • Elevated low-density lipoprotein cholesterol (LDL-C) is a key risk factor for atherosclerotic cardiovascular disease.
  • Statins are primary LDL-C-lowering drugs but can cause musculoskeletal disorders (MSDs), impacting patient adherence.
  • Bempedoic acid (BA) is an alternative lipid-lowering agent with limited muscle activation, though recent data suggest potential muscle-related adverse drug reactions (ADRs).

Purpose of the Study:

  • To compare muscle-related ADRs between bempedoic acid (BA) and atorvastatin (ATO).
  • To evaluate the safety profile of BA concerning muscle-related adverse events in a real-world setting.

Main Methods:

  • Analysis of ADR reports from the European spontaneous reporting system up to June 2024.
  • Disproportionality analysis using Reporting Odds Ratios (RORs) to compare muscle-related ADRs between BA and ATO.
  • Categorization of ADRs by patient demographics and event type.

Main Results:

  • A total of 78,930 ADR reports were analyzed (2,667 for BA-only, 76,137 for ATO-only).
  • Musculoskeletal disorders were significantly more frequent with BA than ATO (ROR 2.25).
  • Muscle discomfort was more associated with BA, while severe events like rhabdomyolysis were more frequent with ATO; BA-related muscle ADRs were generally less severe.

Conclusions:

  • Bempedoic acid (BA) recipients showed increased odds of muscle-related ADR reports compared to atorvastatin (ATO) recipients.
  • Despite higher reporting odds, BA-associated muscle ADRs were characterized by more favorable clinical outcomes and lower severity.
  • Clinicians should consider drug-induced muscle symptoms when prescribing BA, particularly in combination therapy with statins.

Data Reporting and Recording01:24

Data Reporting and Recording

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Receiver Operating Characteristic Plot01:15

Receiver Operating Characteristic Plot

A ROC (Receiver Operating Characteristic) plot is a graphical tool used to assess the performance of a binary classification model by illustrating the trade-off between sensitivity (true positive rate) and specificity (false positive rate). By plotting sensitivity against 1 - specificity across various threshold settings, the ROC curve shows how well the model distinguishes between classes, with a curve closer to the top-left corner indicating a more accurate model. The area under the ROC curve...

Predicting Reaction Outcomes02:24

Predicting Reaction Outcomes

Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

Outcomes of Glycolysis01:13

Outcomes of Glycolysis

Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

Guidelines for Writing Outcome01:11

Guidelines for Writing Outcome

When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

Types of Reports I: Hands-off Report

A hand-off report, also known as a change-of-shift report, is a crucial nursing process that ensures the smooth transition of patient care responsibilities between nursing staff.
Following are the key components and categories of hand-off reports:
