Acebutolol
Acebutolol (trade names Sectral, Prent) is a beta blocker for the treatment of hypertension and arrhythmias.
==Pharmacology==
Acebutolol is a cardioselective beta blocker with ISA (intrinsic sympathomimetic activity; see article on pindolol). It is therefore more suitable than non cardioselective beta blockers, if a patient with asthma or chronic obstructive pulmonary disease (COPD) needs treatment with a beta blocker. (For these reasons, it may be a beta-blocker of choice in inclusion in Polypill strategies). In doses lower than 800mg daily its constricting effects on the bronchial system and smooth muscle vessels are only 10% to 30% of those observed under propranolol treatment, but there is experimental evidence that the cardioselective properties diminish at doses of 800mg/day or more.
The drug has lipophilic properties, and therefore crosses the blood–brain barrier. Acebutolol has no negative impact on serum lipids (cholesterol and triglycerides). No HDL decrease has been observed. In this regard, it is unlike many other beta blockers which have this unfavourable property.
The drug 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. In clinically relevant concentrations, a membrane-stabilizing effect does not appear to play an important role.
