Angina pectoris: effects of lidoflazine on exercise tolerance and chest pain

In a double-blind study involving 24 patients, treatment with lidoflazine in comparison with placebo was associated with a significant improvement in exercise tolerance; the median increase in work performed was 62 percent. This increase was significant at the 6th week of assessment. Ten patients were followed up for a further 2 years. Lidoflazine therapy was associated with a significant improvement in work done over that period. Lidoflazine was well tolerated and apparent adverse effects were minor.
