Oxprenolol (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 hydrophilic ligands 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.
