ATENOLOL

Manufacturer: Proficient Rx LP

Score: 144.0

Quick Summary

Atenolol is a beta blocker used to treat high blood pressure, angina pectoris, and to reduce the risk of heart attack. It works by blocking the action of certain natural chemicals in your body, such as epinephrine, on the heart and blood vessels. This effect lowers the heart rate, blood pressure, and strain on the heart. Atenolol may be used alone or in combination with other medications. It is generally well-tolerated but can cause side effects such as dizziness, fatigue, and nausea. Important safety information includes warnings about exacerbating heart failure, causing bronchospasm in patients with asthma, and potential interactions with other medications. Dosage recommendations vary based on the condition being treated and patient factors like age and kidney function. Special population considerations include use during pregnancy, nursing, pediatric, and geriatric populations, where dose adjustments and careful monitoring may be necessary.
