Montreal--Two newer-generation antimuscarinic agents—solifenacin succinate (VESIcare) and extended-release tolterodine tartrate (Detrol LA)—improve symptoms of overactive bladder, but solifenacin appears to provide superior outcomes, according to a trial conducted in collaboration with the manufacturer of solifenacin. Benefits of solifenacin appear to be due, at least in part, to the availability of two approved doses of the drug, researchers say.
