How effective are Tenormin tablets 25 mg from Japan for hypertension and heart diseases?

Tenormin tablets’ active ingredient is atenolol. It works by blocking β1-adrenergic receptors in the heart, thus lowering blood pressure and slowing down heart rate. Subsequently, Tenormin tablets help to prevent anginal attacks and to control tachyarrhythmia.

Who should use Tenormin tablets 25 mg from Japan?

Tenormin tablets are effective against hypertension, angina, long QT syndrome, acute myocardial infarction, supraventricular tachycardia and ventricular tachycardia. Atenolol is eliminated unchanged in the urine. There is very little hepatic metabolism so Tenormin tablets appear to be safe for patients with liver dysfunction (A. Y. Schure, J. A. DiNardo. Cardiac Physiology and Pharmacology. A Practice of Anesthesia for Infants and Children (Sixth Edition). 2019, Pp. 424-457). Also, atenolol does not cross the blood-brain barrier. However, Tenormin tablets cannot be used in patients with diabetic ketoacidosis, and the blood sugar level should be controlled while taking this medication.
