Overactive bladder syndrome complicates life for many women. 60-70% of women report improvement with treatment but the antikolinergic treatment is often limited by the adverse events, for example dry mouth, obstipation and urinary retention. Mirabegron is a b3-adrenoreceptor agonist which induces detrusor relaxation. Earlier studies has demonstrated similar efficacy comparing Mirabegron with antimuscarinics but a significant reduction of adverse events. The aim of the present study is to survey cardiovascular adverse events with Mirabegron treatment in a general population suffering from overactive bladder syndrome.

Overactive bladder syndrome complicates life for many women. For 30 years the dominant treatment of overactive bladder syndrome has been antimuscarinics as first-line pharmacotherapy. 60-70% of women report improvement with treatment but the therapy is limited by the adverse events, for example dry mouth, obstipation and urin retention. In Sweden, prescription of antimuscarinics has increased by 69% during the period of 2000-2007 which implies an increasing desire to seek treatment.

Mirabegron is a b3-adrenoreceptor agonist which induces detrusor relaxation. Earlier studies have demonstrated similar efficacy when comparing Mirabegron with antimuscarinics but a significant reduction of adverse events. Clinical phase I-III trials have registered an increased pulse rate and effects on blood pressure in some patients. The aim of the present study is to survey cardiovascular adverse events with treatment with Mirabegron in the general population suffering from overactive bladder syndrome.
