SUMMARY:

Atenolol is a Beta-1 Selective Beta Blocker Antihypertensive Agent that is also known by the brand name Tenormin. The common indications are for Hypertension (HTN), Angina, and Post-MI Cardiovascular Event Prevention. It also has an off label use for Migraine Prophylaxis. Dosing range is between 25-200 mg PO qd depending on the indication. Should the patient ever need to discontinue the medication they should be tapered off gradually due to risks of exacerbation of treated indication. Common monitoring parameters include but are not limited to Cr and BP at baseline and periodically thereafter, ECG, and 10-year ASCVD risk assessment. Apple juice and orange juice should be avoided when taking this medication because they may prevent atenolol from being absorbed properly.
