Talc intrapleural aerosol is indicated to prevent recurrence of malignant pleural effusions in symptomatic patients. It is administered during thoracoscopy or open thoracotomy.

Antiperspirants
Agents that are put on the SKIN to reduce SWEATING or prevent excess sweating (HYPERHIDROSIS). (See all compounds classified as Antiperspirants.)
Foreign body granulomas containing talc fibers are to be found in lung, pleura, diaphragm, pericardium, and gastric wall ... .

...Transmission electron microscopy and energy dispersive X-ray spectroscopy /was used to analyze/ the total fibrous and nonfibrous mineral content of the lungs of a series of 14 male smokers with lung cancer but with no history of occupational dust exposure, and of a series of 14 control men matched by age, smoking history and general occupational class. The average concentration of mineral fibers and nonfiberous particles were 3.8 and 2.0 times higher in the group with cancer. Kaolinite, talc, mica, feldspars and crystalline silica comprised the majority of fibrous and nonfibrous particles in both groups.

Mice that received a sterile sc injection of talc were studied by measuring the incorporation of radioactive leucine and glucosamine into liver and plasma protein and the talc gramuloma at various intervals between 2 and 528 hours after injection. Incorporation into plasma proteins indicated a biphasic response with a marked increased incorporation into the perchloric acid insoluble fraction at 21 hours, a return to normal values at 45 hours, and a similar marked increase into the perchloric acid soluble fraction at 45 hours with a gradual return toward normal values. The response was dependent upon the amount of talc injected.

Using radioactive tracer techniques in rats, mice, guinea pigs, and hamsters, no intestinal absorption or translocation of ingested talc to the liver and kidneys was detected.

In hamsters, ...the biological half-life of talc deposited in the alveoli was 7-10 days, and the alveolar clearance was basically complete 4 months after exposure.
