Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

Treatment of respiratory disease in horses where airway obstruction due to
bronchospasm and/or accumulation of mucus is a contributing factor, and improved
mucociliary clearance is desirable. To be used alone or as adjuvant therapy.
In particular :
i) Acute, sub-acute and chronic infections where the presence of mucus and/or micro-
organisms may stimulate bronchospasm or cause airway obstruction and thus an
increase in airway resistance. For example, bronchitis, bronchiolitis and
bronchopneumonia alone, or associated with equine influenza and other viral respiratory
diseases.
ii) Acute, sub-acute and chronic respiratory allergies.
iii) Chronic Obstructive Pulmonary Disease (COPD) in horses.
In cases complicated by the presence of micro-organisms the simultaneous use of
antimicrobial agents is indicated.
