Mechanism of action

When instilled into body cavities (pleural, peritoneal, or pericardial), talc particles trigger an inflammatory response that leads to fibrosis and adhesion of the visceral and parietal surfaces. This mechanical obliteration of the space prevents malignant effusions from reaccumulating. The mechanism is primarily physical and inflammatory rather than pharmacological.
