Theophylline toxicity
1Department of Emergency Medicine, State University of New York at Stony Brook 11794-7400.
Abstract:
Theophylline toxicity continues to be a commonly encountered clinical problem. Patients may present with a vast array of toxic manifestations, including life-threatening cardiovascular and neurologic toxicity. Despite the considerable attention this topic has received in the literature, there remain some important controversies regarding the identification of high risk patients and how best to manage them. This review attempts to summarize the current state of knowledge regarding theophylline toxicity with special emphasis on toxic manifestations and the role of elimination enhancing modalities.
Insights
Theophylline toxicity is a common clinical issue causing severe cardiovascular and neurologic problems. This review focuses on identifying high-risk patients and managing toxicity using elimination-enhancing methods.
Area of Science:
- Clinical Medicine
- Pharmacology
- Toxicology
Background:
- Theophylline toxicity is a frequent clinical challenge with potentially severe outcomes.
- Manifestations range widely, including life-threatening cardiovascular and neurologic effects.
- Controversies persist regarding high-risk patient identification and optimal management strategies.
Purpose of the Study:
- To review the current understanding of theophylline toxicity.
- To emphasize the spectrum of toxic manifestations.
- To discuss the role of elimination-enhancing modalities in management.
Main Methods:
- Literature review of theophylline toxicity.
- Synthesis of current knowledge on clinical presentations.
- Analysis of treatment strategies, including enhanced elimination.
Main Results:
- Theophylline overdose can lead to serious cardiac arrhythmias and seizures.
- Early recognition of risk factors is crucial for patient outcomes.
- Enhanced elimination techniques may be beneficial in severe cases.
Conclusions:
- Theophylline toxicity requires careful patient monitoring and risk stratification.
- Management should address both toxic effects and methods to increase drug clearance.
- Further research is needed to clarify optimal management protocols for high-risk individuals.
