50-96-4 Usage
Uses
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.
Clinical Use
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.
Side effects
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.
Check Digit Verification of cas no
The CAS Registry Mumber 50-96-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 0 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 50-96:
(4*5)+(3*0)+(2*9)+(1*6)=44
44 % 10 = 4
So 50-96-4 is a valid CAS Registry Number.
