Clinical information

Ventipulmin Syrup 25 micrograms/ml — SPC Details

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

Treatment of respiratory disease in horses where it is considered that 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 respiratory allergies.
ii) 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.
iii) Chronic Obstructive Pulmonary Disease (COPD).
In cases complicated by bacterial infection, the administration of antimicrobial agents
is recommended.
