VoSpire ER Chemical Information

albuterol - A racemic mixture of the r-isomer levalbuterol and s-albuterol, a short-acting sympathomimetic agent with bronchodilator activity. Albuterol stimulates beta2-adrenergic receptors in the lungs, thereby activating the enzyme adenylate cyclase that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP). Increased cAMP concentrations relax bronchial smooth muscle, relieve bronchospasms, and reduce inflammatory cell mediator release, especially from mast cells. Albuterol although to a lesser extent, also stimulates beta1-adrenergic receptors, thereby increasing the force and rate of myocardial contraction.
