Ventipulmin Solution for Injection 30 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 muco-ciliary 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 mucu
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 accompanied by bacterial infection the administration of
antimicrobial agents is recommended.

Administer by slow intravenous injection at a dose of 2.7 ml per 100 kg
bodyweight twice daily for as long as necessary. This is equivalent to
twice daily administration of 0.8 micrograms clenbuterol hydrochloride per
kg bodyweight.
Avoid the introduction of contamination during use.

None known.

In clinical use, it has been noted that following intravenous administration
to horses, cases of transient mild muscle tremor and sweating were
observed. It is suggested that a ‘bolus’ effect may have occurred in these
cases and caused transient peripheral vasodilation. This vasodilation is a
feature exhibited by all beta-adrenergic drugs to a greater or lesser
degree. These effects may be minimised by administering the product
slowly.

Do not use in horses with known cardiac disease.

Do not use in cases of known hypersensitivity to clenbuterol
