Sterile talc powder is a mineral, usually used in a powdered form. In cancer treatment, sterile talc powder is used to prevent pleural effusions (an abnormal collection of fluid in the space between the lungs and the chest wall). Sterile talc powder is inserted into the space, causing it to close up, so fluid cannot collect there.
Sterile Talc Powder is a sclerosing agent intended for intrapleural administration supplied in a single use 100 ml brown glass bottle, sealed with a gray, 20 mm stopper and covered with a flip-off seal. Each bottle contains a minimum of 5.0 g of Talc USP (Ultra 2000 Talc), either white or off-white to light gray, asbestos-free and brucite-free grade of talc of controlled particle size. The composition of the talc is ≥ 95% talc as hydrated magnesium silicate. The empirical formula of talc is Mg3Si4O10(OH)2 with a molecular weight of 379.3. Associated naturally occurring minerals include chlorite (hydrated aluminum and magnesium silicate.), dolomite (calcium and magnesium carbonate), calcite (calcium carbonate) and quartz. Talc is practically insoluble in water and in dilute solutions of acids and alkali hydroxides. The finished product has been sterilized by gamma irradiation.
Sterile Talc Powder, administered intrapleurally via a chest tube, is indicated as a sclerosing agent to decrease the recurrence of malignant pleural effusions in symptomatic patients.

Famous quotes containing the words sterile and/or powder:
“Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil. They give us, now and then, some of those luxurious sterile emotions that have a certain charm for the weak.... They are simply cheques that men draw on a bank where they have no account.”
—Oscar Wilde (1854–1900)
“Uncle Ben’s brass bullet-mould
And powder horn, and Major Bogan’s face
Above the fire, in the half-light, plainly said
There’s naught to kill but the animated dead;”
—Allen Tate (1899–1979)
