Effects of Oral Procaterol for Postinfectious Cough in Adults: Single-Centre, Randomized Double-Blind, Placebo-Controlled Trial.

Background: Persistent cough following an upper respiratory tract infection (URTI) is common in clinical practice. We investigated the effects of procaterol on cough-specific quality of life (QoL) and peripheral-airway function among adults suffering from postinfectious cough (PIC).

Methods: This was a prospective, randomized, double-blinded placebo-controlled trial (NCT02349919) conducted at a university hospital.
