We have shown previously that artificial sweeteners, present in carbonated soft drinks, enhanced detrusor muscle contraction. Other constituents of soft drinks are preservatives and antioxidants, we evaluated the effects of two of these, ascorbic acid and citric acid, on the contractile response of isolated rat bladder muscle strips.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Detrusor muscle strips were suspended in a perfusion organ bath. We determined the effect of ascorbic acid and citric acid on the contractile responses to electrical field stimulation (EFS) in the absence and presence of atropine, carbachol, \u03b1, \u03b2 methylene ATP, potassium and calcium.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ascorbic acid and citric acid (10<jats:sup>\u22127<\/jats:sup>M to 10<jats:sup>\u22123<\/jats:sup>M) enhanced the contractile response to 10 Hz EFS compared to control (P\u2009&lt;\u20090.01).
