Application

Clenbuterol hydrochloride has been used:
  • as an agonist for β-adrenergic receptor (β-AR) from chick skeletal muscle
  • to induce hypertrophic effects in masseter, digastric, and temporalis muscles of rat
  • as a reference β-agonist standard in tandem mass spectrometry(MS-MS)

Biochem/physiol Actions

Clenbuterol hydrochloride is a β2-adrenoceptor agonist and bronchodilator. It is effective in improving peak expiratory flow rate (PEFR) in asthma patients. Clenbuterol is also a performance-enhancing drug as it stimulates the central nervous system and improves oxygen transport. Clenbuterol elicits cardio protective functionality in patients with dilated cardiomyopathy.
