(S)-(+)-Albuterol D9

(S)-(+)-Albuterol D9 is a deuterated version of the active pharmaceutical ingredient (S)-(+)-Albuterol, also known as Salbutamol. It is a bronchodilator used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). The mechanism of action of (S)-(+)-Albuterol D9 involves binding to beta-2 adrenergic receptors in the lungs, which leads to relaxation of the smooth muscles surrounding the airways. This results in the widening of the air passages, allowing for easier breathing and improved airflow. Chemically, (S)-(+)-Albuterol D9 is a chiral molecule consisting of a phenethylamine skeleton with a hydroxyl group and a tert-butyl group attached to the carbon atom at the beta position. The deuterium substitution occurs at the methyl group of the tert-butyl moiety. (S)-(+)-Albuterol D9 is typically administered via inhalation, either through a metered-dose inhaler or a nebulizer. It is rapidly absorbed into the bloodstream and has a relatively short half-life of 3-6 hours. While (S)-(+)-Albuterol D9 is generally well-tolerated, common side effects may include tremors, palpitations, and headache. It is important to follow the prescribed dosage and seek medical attention if any adverse reactions occur.
