cysteamine (CAS 60-23-1) — formula C2H7NS, molecular weight 77.15; category organic chemicals.
Documented applications: Uses: Therap Cat: Antidote to acetaminophen, SRP: former, Experimentally as a radioprotective agent and to produce acute and chronic duodenal ulcers in rats., Use (kg, approx.) in Germany (2009): >50, Consumption (g per capita, approx.) in Germany (2009): 0.000611, Calculated removal (%): 92.1, Formulations, Preparations: U.S.- 50 mg (Rx) Cystagon. 150 mg (Rx) Cystagon., General Manufacturing Information: While data specific to cysteamine were not available(SRC, 2005), the literature suggests that some pharmaceutically active compounds originating from human and veterinary therapy are not eliminated completely in municipal sewage treatment plants and are therefore discharged into receiving waters(1). Wastewater treatment processes often were not designed to remove them from the effluent(2). Selected organic waste compounds may be degrading to new and more persistent compounds that may be released instead of or in addition to the parent compound(2). Studies have indicated that several polar pharmaceutically active compounds can leach through subsoils into aquifers(1)..
