Mechanism of action

When instilled into the pleural cavity, talc particles trigger an inflammatory response that leads to adhesion and fusion of the visceral and parietal pleura. This obliteration of the pleural space prevents the reaccumulation of pleural effusion, providing long-term control of recurrent malignant or benign pleural effusions. The mechanism is primarily physical and inflammatory rather than pharmacological.
