This analysis also does not offer any meaningful information about the comparative efficacy of beta blockers in these subgroups purchase nitroglycerin 2.5 mg treatment ingrown hair. Results are summarized in Table 16 below and suggest that beta blockers are equally effective in reducing mortality in subpopulations stratified by gender and race cheap nitroglycerin 6.5mg with amex medicine to stop diarrhea. Observational analyses A 12-month observational study comparing the tolerability of carvedilol (target dose 25 mg daily) in patients (ages >70) with and without diabetes mellitus found the rates of withdrawal due to adverse events (bradycardia, bronchospasm) were low in both the diabetes and nondiabetes 181 subgroups (6% compared with 3%).

Once desired blood pressure was reached, participants were further randomized to receive atenolol or reserpine. Beta blockers Page 54 of 122 Final Report Update 4 Drug Effectiveness Review Project Carvedilol Prescribing information for carvedilol (http://us. We found no other source of publication of results from this subgroup analysis. A number of additional meta-analyses have been published that evaluate the effects of carvedilol in subgroups of patients based on demographics and/or comorbidities. The United 183 States Carvedilol Heart Failure Study Group published an analysis of the pooled results from a 84-87 stratified set of 3 fair-quality and 1 poor-quality concurrently conducted protocols, discussed in detail above, that showed no significant interaction between race and carvedilol treatment in 89 patients with mild to moderate heart failure. More recent analyses from the COPERNICUS trial show that carvedilol had similar effects regardless of age and gender in patients with severe heart failure. The most recent and largest manufacturer-funded meta-analysis (N=5757) of published and unpublished data from 7 clinical trials focused on evaluating the effects of carvedilol in 184 patients with heart failure, with and without comorbid diabetes. Consistent with previous analyses, the main findings confirmed that similar reductions in risk of all-cause mortality were seen in heart failure patients, regardless of diabetes status. The relative risk reduction in the subgroup of patients with diabetes was 28% (95% CI, 3 to 46) and was 37% (95% CI, 22 to 48) in the non-diabetic patients. Labetolol Product information for labetalol (http://www. However, we did not find any evidence of differential efficacy of labetalol relative to age. Metoprolol 185 A fair-quality review that pooled results from 5 placebo-controlled trials of metoprolol (Amsterdam, Belfast, Goteborg, Stockholm, Lopressor Intervention Trial) found that neither age nor gender had a significant influence on mortality. When considered individually, results from 186 the Goteborg Metoprolol Trial show a nonsignificant trend that patients aged 65 to 74 years had a more marked reduction in mortality at 3 months post-myocardial infarction (45%) than did all patients aged 40 to 74 (36%). Results from the MERIT-HF trial also reported that neither age nor gender had any influence on the effects of metoprolol CR in patients with mild to moderate heart failure. A subgroup analysis of the MERIT-HF trial evaluated the influence of comorbid diabetes 187 on the effects of metoprolol CR. This analysis found higher rates of all-cause mortality in the placebo group when compared to metoprolol (12. Metoprolol CR also significantly reduced risks of hospitalizations for worsening heart failure (including those patients identified as having severe heart failure) regardless of diabetic status. Beta blockers Page 55 of 122 Final Report Update 4 Drug Effectiveness Review Project Propranolol 67 The fair-quality, placebo-controlled Beta Blocker Heart Attack Trial comprised of 3837 patients found that the protective of propranolol on mortality 25 months (average follow-up) following myocardial infarction was equivalent regardless of age or gender. Nebivolol Subgroup analysis of the SENIORS trial found no significant differences in the effect of nebivolol on subpopulations of gender, ejection fraction, age, diabetes, and prior myocardial 72 infarction. SUMMARY Results of this review are summarized below in Table 17 by key question and in Table 18 by beta blocker. Strength of the evidence a Strength of evidence Conclusion Key Question 1. Hypertension Overall grade: Poor No head-to-head trials of long-term (≥6 months) health or quality-of-life outcomes. Reliable indirect comparisons cannot be made by evidence from 3 long-term placebo-controlled trials of propranolol and atenolol. Angina Overall grade: Fair No significant differences in 6 head-to-head trials of carvedilol compared with metoprolol, pindolol compared with propranolol, betaxolol, and propranolol, and betaxolol compared with metoprolol in patients with stable angina. Atenolol equivalent to bisoprolol in patients with chronic stable angina and chronic obstructive pulmonary disease. Atenolol equivalent to labetalol when added to chlorthalidone in patients with chronic stable angina. One short-term, placebo-controlled trial of propranolol did not add any meaningful evidence of comparative efficacy in the above parameters.
