Original Abstract of the Article

Main Research Findings

Aminophylline, a commonly used bronchodilator, has been found to have various side effects, particularly in relation to the cardiovascular system. 4 showed that aminophylline increased heart rate and contractility in human pluripotent stem cell-derived cardiomyocytes, suggesting an arrhythmogenic potential. While aminophylline has been investigated as a potential cancer treatment, it was found to be less effective than theophylline and exhibited high cytotoxicity at higher doses. 25 Additionally, aminophylline may cause changes in blood pressure, heart rate, and heart rate variability in newborns, particularly in cases of meconium aspiration syndrome (MAS). 1

Reasons for Side Effects

The side effects of aminophylline arise from its mechanism of action. Aminophylline inhibits the breakdown of intracellular cyclic AMP (cAMP), leading to increased cAMP levels. This elevation in cAMP can affect various cellular activities, potentially contributing to increased heart rate and blood pressure as well as arrhythmias. 4 Aminophylline also blocks adenosine receptors, which are involved in vasodilation. This blockade can lead to vasoconstriction and subsequently, higher blood pressure. 17

Common Side Effects

Cardiovascular

Aminophylline can lead to increased heart rate, blood pressure, and arrhythmias. 4 In newborns, aminophylline can impact blood pressure, heart rate, and heart rate variability. 1

Gastrointestinal

Aminophylline may cause gastrointestinal side effects such as stomach pain, nausea, vomiting, and diarrhea. 26

Nervous System

Aminophylline can lead to neurological side effects including headache, dizziness, tremors, anxiety, and insomnia. 19

Respiratory

While aminophylline is primarily used for asthma treatment, it can rarely cause difficulty breathing. 21

Countermeasures for Side Effects

Cardiovascular

Close monitoring of blood pressure, heart rate, and electrocardiogram is essential during aminophylline administration. Caution is advised for individuals with pre-existing cardiovascular conditions, the elderly, and newborns. 4 1

Gastrointestinal

Taking aminophylline after meals may help minimize stomach irritation. 26

Nervous System

Patients should be advised to avoid driving or operating machinery while taking aminophylline. 19

Comparison between Studies

Commonalities

Multiple studies have demonstrated the potential of aminophylline to affect the cardiovascular system, with findings including increased heart rate, blood pressure, and arrhythmias. 4 1

Differences

The manifestation of aminophylline's side effects can vary based on factors such as dosage, administration method, and individual patient characteristics. It's crucial to acknowledge that the results from different studies might have been obtained under distinct conditions.

Notes on Applying to Real Life

While aminophylline is a valuable bronchodilator, it's important to be aware of the potential for cardiovascular side effects. Individuals with heart conditions, the elderly, and newborns should exercise particular caution. Always follow your doctor's instructions when taking aminophylline. If you suspect any side effects, seek immediate medical attention. 4 1

Limitations of Current Research

The available research on the side effects of aminophylline is still limited. More studies are needed, particularly regarding long-term side effects. Furthermore, side effect profiles can vary significantly depending on individual patient characteristics and genetic background.

Future Research Directions

Additional research is crucial to further understand the side effects of aminophylline. This includes investigations into long-term side effects and how individual factors, such as patient condition and genetics, influence the occurrence of side effects.

Conclusion

Aminophylline is an effective bronchodilator but carries the risk of cardiovascular side effects. Always adhere to your doctor's instructions when taking aminophylline. If you experience any suspected side effects, seek immediate medical advice.
