Description
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/3240917

Zilpaterol is an agonist of β2-adrenergic receptor. Zilpaterol exerts bronchospasmolytic action. Zilmax® (4.8% Zilpaterol hydrochloride) is used to increase rate of bodyweight gain, improve feed efficiency, and increase carcass leanness in cattle fed in confinement for a period of 20-40 consecutive days at the end of the feeding period before slaughter.

Sample Use Guides

Zilmax® (4.8% Zilpaterol hydrochloride) is used to increase rate of bodyweight gain, improve feed efficiency, and increase carcass leanness in cattle fed in confinement for a period of 20-40 consecutive days at the end of the feeding period before slaughter. Zilpaterol hydrochloride should be mixed into the feed at a level of 7.5 mg/kg on a 90% dry matter basis. This represents a dose of approximately 0.15 mg/kg bw or 60 to 90 mg zilpaterol hydrochloride per animal per day.
Route of Administration: Oral
Zilpaterol hydrochloride at 1 µM decreased β1-adrenergic receptor mRNA, and 0.01 and 1 µM Zilpaterol hydrochloride decreased β2-adrenergic receptor and β3-adrenergic receptor mRNA in bovine myoblasts.
