Tolterodine (Detrol, Detrusitol) is an antimuscarinic drug that is used to treat urinary incontinence.

Contents

[edit] Pharmacology

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. It is marketed and manufactured by Pfizer.

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.

[edit] Side effects

Known side effects:

The following reactions have been reported in patients who have taken tolterodine since it has become available:

Contraindications:

Not to be used in patients with myasthenia gravis and angle closure glaucoma.

[edit] Marketing

New York Times reporter Melody Petersen, who wrote the book Our Daily Meds: How the Pharmaceutical Companies Transformed Themselves into Slick Marketing Machines and Hooked the Nation on Prescription Drugs (Farrar, Straus and Giroux, 2008), said that "the most outrageous thing" she saw covering the pharmaceutical industry was a PowerPoint presentaton on "Creating a Disease," which created a disease called "overactive bladder" for the purpose of marketing Detrol. Doctors try to manage incontinence in non-pharmaceutical ways, she said. Detrol became a blockbuster, said Petersen, despite the adverse effect of severe memory problems.[1]

Detrusor overactivity (DO, contraction of the muscular bladder wall) is the most common form of 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 me measured by urodynamic studies. Treatment is bladder retraining or with drugs that inhibit bladder contractions such as oxybutinin and tolterodine.
