It is marketed by Pfizer in Canada and the United States by its brand name Detrol. In Egypt it is also found under the trade names Tolterodine by Sabaa and Incont L.A. by Adwia.
Detrusor overactivity (DO, contraction of the muscular bladder wall) is the most common form of urinary incontinence (UI) in older adults. It is characterized by uninhibited bladder contractions causing an uncontrollable urge to void. Urinary frequency, urge incontinence and nocturnal incontinence occur. Abnormal bladder contractions that coincide with the urge to void can be measured by urodynamic studies. Treatment is bladder retraining, pelvic floor therapy or with drugs that inhibit bladder contractions such as oxybutinin and tolterodine.
Tolterodine, although it acts on all types of receptors, has fewer side effects than 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.
