Butaxamine

Butaxamine ( INN, also known as butoxamine) is a β-selective beta blocker. Its primary use is in experimental situations in which blockade of β receptors is necessary to determine the activity of the drug (i.e. if the β receptor is completely blocked, but the given effect is still present, the given effect is not a characteristic of the β2 receptor). It has no clinical use. An alternative name is α-(1-[t-Butylamino]ethyl)-2,5-dimethoxybenzyl alcohol.
