Tenormin 50mg tablets contain atenolol, a beta-blocker medication used to treat high blood pressure, angina, and certain heart rhythm disorders. Each pack contains 28 tablets manufactured by AstraZeneca, designed for once-daily oral administration. Atenolol belongs to a class of medications called beta blockers that work by blocking the action of certain natural chemicals in the body (such as epinephrine) that affect the heart and blood vessels. This helps reduce blood pressure, heart rate, and strain on the heart. The tablets should be taken as prescribed by your healthcare provider, typically once daily. This is a prescription-only medication that requires regular medical supervision. The distinctive packaging features AstraZeneca branding with orange and purple color scheme.
