'''Oxprenolol''' ('''Trasacor''', '''Trasicor''', '''Coretal''', '''Laracor''', '''Slow-Pren''', '''Captol''', '''Corbeton''', '''Slow-Trasicor''', '''Tevacor''', '''Trasitensin''', '''Trasidex''') is a non-selective [[beta blocker]] with some intrinsic [[sympathomimetic amine|sympathomimetic]] activity. It is used for the treatment of [[angina pectoris]], abnormal [[heart]] rhythms and [[arterial hypertension|high blood pressure]].
==Overview==
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 [[Central nervous system|CNS]]-related side effects than hydrophilic ligands such as [[atenolol]], [[sotalol]] and [[nadolol]].<ref>{{cite journal |author=McDevitt DG |title=Comparison of pharmacokinetic properties of beta-adrenoceptor blocking drugs |series=8 |journal=Eur.

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.[1]

Stereochemistry
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. [3]
