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.

A trial of clenbuterol in bronchial asthma.

Anderson G and Wilkins E

Thorax, 32(6), 717-719 (1977)

The beta-adrenoceptor agonist clenbuterol is a potent inhibitor of the LPS-induced production of TNF-alpha and IL-6 in vitro and in vivo.

Inflammation research : official journal of the European Histamine Research Society ... [et al.], 48(9), 497-502 (1999-10-16)

To investigate the suppressive effects of the beta-agonist clenbuterol on the release of TNF-alpha and IL-6 in a lipopolysaccharide (LPS)-model of inflammation, both in vitro and in vivo. Human U-937 cell line (monocyte-derived macrophages), and male Wistar rats (200-250 g).
