MedKoo Cat#: 592481 | Name: Albuterol stearate

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Albuterol stearate is a salt of Albuterol -- a β2-AR agonist. Albuterol is a short-acting, selective beta2-adrenergic receptor agonist used in the treatment of asthma and COPD. It is 29 times more selective for beta2 receptors than beta1 receptors giving it higher specificity for pulmonary beta receptors versus beta1-adrenergic receptors located in the heart.
