Final answer:
Levalbuterol and Salbutamol (Albuterol) are medications used to treat and prevent bronchospasm in obstructive pulmonary diseases such as asthma and bronchitis. Salbutamol, with the molecular formula C13H21NO3, is synthesized from norepinephrine and requires purification to reach drug-quality purity.
Step-by-step explanation:
The two medications mentioned in the question are Levalbuterol and Salbutamol (Albuterol). Levalbuterol and Salbutamol are medications used to treat and prevent bronchospasm, which is constriction of the muscles in the airways. These drugs are particularly helpful for individuals with asthma, bronchitis, and other obstructive pulmonary diseases. Salbutamol, which is also known by the common name Albuterol, has the molecular formula C13H21NO3 and is synthesized from norepinephrine. It requires several chemical steps to purify it into drug-quality purity, with the process being subject to percent yields.
