Major Research Findings
Propranolol is a medication widely used to treat cardiovascular diseases in children. However, several studies have shown that propranolol can cause various side effects in children. For example, 27 found that children admitted to the cardiovascular intensive care unit (CVICU) experienced side effects such as bradycardia, hypoglycemia, and initiation or escalation of inotropes after oral propranolol administration. Additionally, reported side effects such as bradycardia, hypoglycemia, and respiratory distress in infants receiving propranolol.
The side effects of propranolol can vary depending on factors such as age, dosage, and the patient's condition. To minimize these side effects, it is crucial to carefully evaluate the patient's condition before using propranolol and adjust the dosage appropriately. Regular monitoring of the patient's heart rate, blood pressure, and blood sugar levels is also essential during propranolol administration.
Reasons for Side Effects
Propranolol is known as a beta-blocker, which works by binding to beta receptors in the heart and blood vessels, reducing the heart's contractility and dilating blood vessels. This action can lead to a slower heart rate and lower blood pressure. Propranolol also has the effect of lowering blood sugar levels. These actions are thought to be the cause of propranolol's side effects.
Common Side Effects
Bradycardia
Propranolol can cause bradycardia because it slows down the heart rate. 27 found bradycardia in 27 (11%) children admitted to the CVICU. also reported bradycardia as a side effect of propranolol in infants.
Hypoglycemia
Propranolol can cause hypoglycemia because it lowers blood sugar levels. 27 found hypoglycemia in 46 (19%) children admitted to the CVICU. also reported hypoglycemia as a side effect of propranolol in infants. 5 reported severe hypoglycemia in infants treated with propranolol.
Respiratory Distress
reported respiratory distress as a side effect of propranolol in infants.
Gastrointestinal Symptoms
29 suggests that propranolol can cause gastrointestinal side effects.
Neuropsychiatric Symptoms
Propranolol can cause neuropsychiatric symptoms such as dizziness, headache, fatigue, insomnia, and depression. 16 reported hallucinations as a neuropsychiatric side effect in patients taking carvedilol, a beta-blocker similar in structure to propranolol.
Others
Other side effects of propranolol may include rash, itching, swelling, liver dysfunction, and kidney dysfunction.
Side Effect Management
Bradycardia
If bradycardia occurs due to propranolol, the dosage may need to be reduced or the medication discontinued. Pacemaker treatment may also be necessary.
Hypoglycemia
If hypoglycemia occurs due to propranolol, it is necessary to consume glucose. The dosage may need to be reduced or the medication discontinued. Special attention is required for patients with a history of diabetes.
Respiratory Distress
If respiratory distress occurs due to propranolol, the medication should be discontinued. Oxygen therapy may be necessary if needed.
Gastrointestinal Symptoms
If gastrointestinal symptoms occur due to propranolol, measures such as dietary therapy and drug therapy may be necessary. The dosage may need to be reduced or the medication discontinued.
Neuropsychiatric Symptoms
If neuropsychiatric symptoms occur due to propranolol, the medication should be discontinued. Consultation with a psychiatrist may be necessary if needed.
Others
If other side effects occur due to propranolol, consult with a doctor.
Comparison Between Studies
Commonalities
Multiple studies have shown that propranolol can cause side effects such as bradycardia and hypoglycemia in children. Moreover, the side effects of propranolol can vary depending on factors such as age, dosage, and the patient's condition.
Differences
Each study examined different types and frequencies of side effects, and the age groups studied were different, making it difficult to make direct comparisons. For example, 27 focused on children admitted to the cardiovascular intensive care unit (CVICU), while focused on infants.
Caution for Real-Life Applications
Propranolol is an effective medication for treating cardiovascular diseases in children, but the risk of side effects needs to be considered. It is important to consult with a doctor and adjust the dosage appropriately when using propranolol. Regular monitoring of the patient's heart rate, blood pressure, and blood sugar levels is also essential during propranolol administration. If you suspect any side effects from propranolol, consult with a doctor immediately.
Current Limitations in Research
Research on the side effects of propranolol is still insufficient. In particular, there are many unknown aspects regarding the long-term side effects of propranolol in children, and further research is needed.
Future Research Directions
Research on the side effects of propranolol should be conducted in the following directions.
- Long-term side effect research on propranolol in children
- Research on predictive factors for propranolol side effects
- Research on measures to reduce propranolol side effects
Conclusion
Propranolol is an effective medication for treating cardiovascular diseases in children, but the risk of side effects such as bradycardia and hypoglycemia needs to be considered. It is important to consult with a doctor and adjust the dosage appropriately when using propranolol. Regular monitoring of the patient's heart rate, blood pressure, and blood sugar levels is also essential during propranolol administration. If you suspect any side effects from propranolol, consult with a doctor immediately.
