title: Effect of slow oxprenolol and a combination of slow oxprenolol and cyclopenthiazide on plasma lipoproteins.
abstract: The effect of slow oxprenolol on plasma lipoprotein concentrations was compared to that of combined therapy with slow oxprenolol and cyclopenthiazide. The design of the study was a double blind between patient investigation in which 9 subjects with mild hypertension received slow oxprenolol and 11 slow oxprenolol and cyclopenthiazide. Plasma lipoproteins were analysed at 0, 2, 4, 8, 12 and 16 weeks. Slow oxprenolol given alone resulted in a significant rise in plasma and low density lipoprotein (LDL) cholesterol concentration whereas combined therapy with slow oxprenolol and cyclopenthiazide produced significant rises in plasma and very low density lipoprotein (VLDL) triglyceride. If one accepts that a rise in plasma or LDL cholesterol increases atherogenic risk more than a rise in plasma or VLDL triglyceride combined therapy is preferable.
