Oxprenolol

Oxprenolol (brand names Trasacor, Trasicor, Coretal, Laracor, Slow-Pren, Captol, Corbeton, Slow-Trasicor, Tevacor, Trasitensin, Trasidex) is a non-selective beta blocker with some intrinsic sympathomimetic activity. It is used for the treatment of angina pectoris, abnormal heart rhythms and high blood pressure. Oxprenolol (brand names Trasacor, Trasicor, Coretal, Laracor, Slow-Pren, Captol, Corbeton, Slow-Trasicor, Tevacor, Trasitensin, Trasidex) is a non-selective beta blocker with some intrinsic sympathomimetic activity. It is used for the treatment of angina pectoris, abnormal heart rhythms and high blood pressure. Oxprenolol is a lipophilic beta blocker which passes the blood–brain barrier more easily than water-soluble beta blockers. As such, it is associated with a higher incidence of CNS-related side effects than beta blockers with more hydrophilic molecules such as atenolol, sotalol and nadolol. Oxprenolol is a potent beta blocker and should not be administered to asthmatics under any circumstances due to their low beta levels as a result of depletion due to other asthma medication, and because it can cause irreversible, often fatal, airway failure and inflammation. Oxprenolol is a beta blocker. In addition, it has been found to act as an antagonist of the serotonin 5-HT1A and 5-HT1B receptors with respective Ki values of 94.2 nM and 642 nM in rat brain tissue. Oxprenolol is a chiral compound, the beta blocker is used as a racemate, e. g. a 1:1 mixture of (R)-(+)-oxprenolol and (S)-(–)-oxprenolol. Analytical methods (HPLC) for the separation and quantification of (R)-(+)-oxprenolol and (S)-(–)-oxprenolol in urine and in pharmaceutical formulations have been described in the literature.
