oxybutynin (M3 and M1 selective, but more so in the parotid than in the bladder) as tolterodine targets the bladder more than other areas of the body.  This means that less drug needs to be given daily (due to efficient targeting of the bladder) and so there are fewer side effects.Tolterodine, although it acts on all types of receptors, has fewer side effects than other antimuscarinics eg. Tolterodine acts on M1, M2, M3, M4 and M5 subtypes of muscarinic receptors whereas modern antimuscarinic treatments for overactive bladder only act on M3 receptors making them more selective.

  Tolterodine tartrate , with CAS number of 124937-52-6, can be called 2-((1R)-3-(Bis(1-methylethyl)amino)-1-phenylpropyl)-4-methylphenol (2R,3R)-2,3-dihydroxybutanedioate (1:1) (salt) ; 2,3-Dihydroxybutandisäure--2-{(1R)-3-[bis(1-methylethyl)amino]-1-phenylpropyl}-4-methylbenzolol(1:1) ; 2-[(1R)-3-(Diisopropylamino)-1-phenylpropyl]-4-methylphenol 2,3-dihydroxysuccinate (1:1) ; acide 2,3-dihydroxybutanedioïque - 2-{(1R)-3-[bis(1-méthyléthyl)amino]-1-phénylpropyl}-4-méthylphénol (1:1) . Tolterodine tartrate (CAS NO.124937-52-6) is used to treat urinary incontinence.Tolterodine is an antimuscarinic drug.
