Albuterol (Salbutamol) Has N-t-butyl and a salicyl alcohol phenyl ring which gives it optimal β2-selectivity. [14] Salbutamol is a short-acting β2-agonist, but has a rapid onset of action. [18] Its onset by inhalation is within 5 minutes. The hydroxyl group on the β-carbon is a mixture of S- and R-isomers, where the R-isomer is the active one.
Corticosteroids and bronchodilators such as salbutamol (albuterol USAN) are often used, and sometimes in combination with ipratropium. The reason these pharmaceuticals are inhaled instead of ingested is in order to target their effect to the respiratory tract , which speeds onset of action of the medicine and reduces side effects, compared to ...
The suppression of contractions is often only partial and tocolytics can only be relied on to delay birth for a matter of days. Depending on the tocolytic used, the pregnant woman or fetus may require monitoring (e.g., blood pressure monitoring when nifedipine is used as it reduces blood pressure; cardiotocography to assess fetal well-being).
