Trospium is an antimuscarinic, antispasmodic agent. Trospium is used to treat the symptoms of overactive bladder (OAB). overactive bladder is a condition that causes the bladder muscles to contract uncontrollably. Chemically it is a quaternary ammonium cation which causes it to stay in periphery rather than crossing the blood–brain barrier. It works by causing the smooth muscle in the bladder to relax.Synthink is a most trusted source of Trospium Degradation Impurity, Trospium Genotoxic impurity, Trospium Process Impurity, USP related compound, Trospium Nitrosamine impurity, N-Nitroso impurity etc. which are listed on this page.
