Butanamide,N-[3-acetyl-4-[2-hydroxy-3-[(1-methylethyl)amino]propoxy]phenyl]- (37517-30-9)

 Acebutolol ,its cas register number is 37517-30-9. It also can be called Prent ; Acetobutolol ; Neptal and Sectral . It is a beta blocker for the treatment of hypertension and arrhythmias. Acebutolol (CAS NO.37517-30-9) is a cardioselective beta blocker with ISA, and if a patient with Asthma bronchiale or chronic obstructive pulmonary disease (COPD) needs treatment with a beta blocker, it is therefore more suitable than non cardioselective beta blockers. It has no negative impact on serum lipids and works in hypertensive patients with high, normal, or low renin plasma concentrations, although acebutolol may be more efficient in patients with high or normal renin plasma concentrations. It is well absorbed from the GI tract and undergoes extensive hepatic metabolization resulting in the desbutyl amine acetolol which is readily converted into diacetolol. Altogether, 5 to 6% of all patients treated have to discontinue Acebutolol (CAS NO.37517-30-9) due to intolerable side effects.
