Yes, there’s a branded version of Trospium called Regurin.
It’s available in either 20mg of trospium chloride, or 60mg prolonged-release capsules called Regurin XL. They are essentially the same, but Trospium is the generic version and Regurin is the branded version, so they may have different packaging, appearance, and prices. Generally, generic versions of medications are cheaper than branded ones.
