Clenbuterol is a beta-2-adrenergic agonist which provides bronchodilating properties as well as other effects, with minimum effect on the cardiovascular system. It is provided as a colorless, palatable syrup. Ventipulmin Syrup (clenbuterol hydrochloride) is antagonized by beta-adrenergic blocking agents.

For use in horses not intended for food.

Each ml contains: Clenbuterol HCl 72.5 mcg.

Contraindications: Ventipulmin Syrup antagonizes the effects of prostaglandin F₂ alpha and oxytocin. Ventipulmin Syrup should not be used in pregnant mares near term. Because tachycardia may occur, Ventipulmin Syrup should not be used in horses suspected of having cardiovascular impairment.

Warning: The effect on reproduction in breeding stallions and brood mares has not been determined. Treatment starting with dosages higher than the initial dose is not recommended.

Human Warnings: This product is not for human use or for use in animals intended for food. Keep out of the reach of children. In case of accidental ingestion, contact a physician immediately. Ingestion of Ventipulmin Syrup may cause undesirable reactions. Clenbuterol, like other beta adrenergic agonists, can produce significant cardiovascular effects in some people as evidenced by elevated pulse rate, blood pressure changes and/or ECG changes.
