Evaluation of inhaled procaterol for potential assist use in patients with stable chronic obstructive pulmonary disease

ABSTRACT

Objectives: International guidelines recommend the use of long-acting bronchodilators for the treatment of chronic obstructive pulmonary disease [COPD], but the usefulness of short-acting bronchodilator assist use for stable COPD remains uncertain. The purpose of the present study was to objectively demonstrate the effects of assist use of procaterol, a short-acting Beta[2]-agonist, on the respiratory mechanics of stable COPD patients treated with a long-acting
