Alprenolol, oralfeprol,alpheprol, andalprenololum (Gubernal,Regletin,Yobir,Apllobal,Aptine,Aptol Duriles), is a non-selectivebeta blocker as well as a5-HT_1A and5-HT_1B receptor antagonist,^[1] used in the treatment ofangina pectoris.^[2] It is no longer marketed byAstraZeneca, but may still be available from otherpharmaceutical companies orgenerically.

Pharmacology

[edit]

Pharmacokinetics

[edit]

Thebrain-to-blood ratio of alprenolol in humans has been found to be 16:1.^[3] For comparison, the brain-to-blood ratio of the highlylipophilic propranolol was 15:1 to 26:1 and of thehydrophilic atenolol was 0.2:1.^[3]
