3,4-ジヒドロキシ-α-[1-(イソプロピルアミノ)プロピル]ベンジルアルコール·塩酸塩 化学特性,用途語,生産方法
使用
Isoetharine Hydrochloride is hydrochloride salt of isoetharine which is β2-adrenergic receptor agonist. It can be used to give quick relief for bronchospasm and asthma. However, It may be potent in producing resistantce to β-adrenoceptor stimulants.
臨床応用
The α-ethyl group confers β2-selectivity, and the β-hydroxyl group and catechol nucleus makes
this a direct-acting drug. It is susceptible to COMT metabolism; however, the α-ethyl group
inhibits MAO. Therefore, one would expect some oral activity.
副作用
Isoetharine is dispensed as a solution only for inhalation administration to treat reversible
bronchospasm of asthma. It has fallen into relative disuse, because with high doses, there is a
significant incidence of cardiovascular (β1-receptor) adverse effects and it has a low β2-receptor
potency compared to newer β2-selective agonists. It has a 2- to 4-minute onset of action when
inhaled and a duration of action of 3 hours. Isoetharine has adverse effects similar to those of
EPI, including palpitations, tachycardia, nausea and vomiting, dizziness, tremor, and headache.
Isoetharine may cause decreased levels of theophylline when coadministered. Cardiovascular
effects are a concern when isoetharine is taken with other asthma drugs.
