tolterodine-tartrate and Cardiovascular-Diseases

This analysis was conducted to investigate the cardiovascular (CV) safety outcomes from the MILAI II study. MILAI II was conducted to evaluate the long-term safety and efficacy of antimuscarinic add-on therapy to mirabegron over 52 weeks in patients with overactive bladder (OAB) symptoms.. MILAI II consisted of a 2-week screening period (patients received mirabegron 50 mg once daily) plus a 52-week treatment period (patients were randomized to receive a combination of mirabegron 50 mg/d plus solifenacin 5 mg/d, propiverine 20 mg/d, imidafenacin 0.2 mg/d, or tolterodine 4 mg/d). CV safety was assessed using treatment-emergent adverse events (TEAEs), vital signs, and 12-lead electrocardiograms (ECGs). Vital signs and ECG data were evaluated for each patient using worst post-baseline values reported.. Of 647 patients, 570 (88.1%) were female with a mean age of 65 years. CV history at baseline and CV-related concomitant medication use throughout the study were balanced between groups. The incidences of overall and drug-related CV TEAEs were ≤8.1% and ≤6.2%, respectively, for all groups. The most common TEAEs were ECG T wave amplitude decreased, ECG QT prolonged, and ventricular extrasystoles. Overall, 36 TEAEs of interest related to the CV system that were possibly/probably related to treatment were reported with similar incidences for each group. For the worst post-baseline vital signs and ECGs, no relationships were noted in terms of either timing or treatment group.. A favorable CV safety profile was observed following long-term combination treatment with mirabegron and an antimuscarinic in patients with OAB symptoms.
