Atenolol-associated cholestasis.

Atenolol, a beta 1-selective beta-adrenergic receptor-blocking agent, is frequently used for the treatment of hypertension and angina pectoris. We report our experience with a patient who developed cholestatic hepatitis related to the initiation of therapy with atenolol with prompt resolution of symptoms and biochemical abnormalities upon discontinuation of this medication. A review of the literature failed to demonstrate any prior report of atenolol-associated hepatic injury. Although rare, because of the common use of atenolol, clinicians should be aware of this potential adverse effect.
