Clenbuterol (Broncodil and trade) is a direct-acting sympathomimetic agent with mainly beta-adrenergic activity and a selective action on β2 receptors (a β2 agonist). It has properties similar to those of salbutamol. It is used as a bronchodilator in the management of reversible airways obstruction, as in asthma and in certain patients with chronic obstructive pulmonary disease. The uses, applications, and the synthetic pathways of this drug are outlined. Physical characteristics including: ionization constant, solubility, X-ray powder diffraction pattern, thermal methods of analysis, UV spectrum, IR spectrum, mass spectrum are all produced. This profile also includes the monograph of British Pharmacopoeia, together with several reported analytical methods including spectrophotometric, electrochemical, chromatographic, immunochemical methods, and capillary electrophoretic methods. The stability, the pharmacokinetic behavior, and the pharmacology of the drug are also provided.
