Contrast media and bronchospasm: a study with iopamidol
Clinical Radiology
|March 1, 1983
Summary
New low-osmolality contrast media, like iopamidol, cause significantly less bronchospasm than conventional media. This finding is important for understanding and potentially preventing severe reactions to radiological contrast agents.
Area of Science:
- Radiology
- Pulmonary Medicine
- Pharmacology
Background:
- Intravenous conventional radiological contrast media can induce bronchospasm.
- This effect is often clinically silent but present in most patients.
- The mechanism linking silent and severe bronchospasm is not fully understood.
Purpose of the Study:
- To compare the bronchospastic effects of a new low-osmolality contrast medium (iopamidol) with conventional media.
- To investigate the clinical significance of reduced bronchospasm with iopamidol.
Main Methods:
- Administration of conventional and low-osmolality contrast media intravenously.
- Assessment of bronchospasm incidence and severity.
- Comparison of effects between different contrast media types.
Main Results:
- Conventional contrast media produced noticeable bronchospasm in most patients.
- The low-osmolality medium iopamidol demonstrated significantly less pronounced bronchospasm.
- The reduction in bronchospasm with iopamidol was a key finding.
Conclusions:
- Low-osmolality contrast media like iopamidol may offer a safer alternative regarding bronchospasm.
- Further research is warranted to confirm if reduced bronchospasm correlates with decreased risk of severe reactions.
- This observation has implications for patient safety in radiological procedures.

01:24Antiasthma Drugs: Methylxanthines
Theophylline, a member of the methylxanthine class of bronchodilators, has long been used in asthma management. While its exact mechanism of action is not fully understood, it is believed to have multiple effects on various cellular processes.
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...

01:20Antiasthma Drugs: Muscarinic Receptor Antagonists
Muscarinic receptor antagonists, also known as antimuscarinic agents, are a class of bronchodilators used to treat asthma, although they are more commonly used to treat COPD. They work by inhibiting the action of acetylcholine (ACh), a neurotransmitter, on muscarinic receptors found in the airways.
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
