Atenolol Tablets

It is a selective β1-adrenergic receptor blocker with no membrane stabilizing effect and endogenous sympathomimetic activity. However, it does not inhibit the bronchodilator effect of isoproterenol. Its mechanism of lowering blood pressure and reducing myocardial oxygen consumption is the same as that of propranolol. Large-scale clinical trials have confirmed that atenolol can reduce the mortality rate of acute myocardial infarction within 0 to 7 days. The therapeutic dose has no significant inhibition on myocardial contractility.

The main chemical component is Atenolol. The chemical name is 4-[3-[(1-methylethyl)amino-2-hydroxy]propoxy]phenylacetamide

It is used to treat hypertension, angina pectoris, myocardial infarction, and can also be used for arrhythmia, hyperthyroidism, and pheochromocytoma.

Oral. The usual dosage for adults is 6.25-12.5 mg (1/4-1/2 tablet) each time, twice a day, and then increase or decrease to 50-200 mg (2-8 tablets) as needed and tolerated. See the instructions for details.

In patients with myocardial infarction, the most common adverse reactions are hypotension and bradycardia; other reactions may include dizziness, cold limbs, fatigue, weakness, gastrointestinal discomfort, depression, hair loss, thrombocytopenia, psoriasis-like skin reactions, psoriasis exacerbation, rash and dry eyes, etc. Rarely, it may cause heart block in sensitive patients.

1. II-III degree heart block. 2. Cardiogenic shock. 3. Sick sinus syndrome and severe sinus bradycardia.

When used in combination with other antihypertensive drugs and diuretics, their antihypertensive effect can be enhanced. Be especially cautious when using Class I antiarrhythmic drugs, verapamil, and anesthetics. β-blockers can aggravate the rebound of hypertension caused by discontinuation of clonidine. If the two drugs are used in combination, this drug should be discontinued a few days before discontinuation of clonidine. If this drug is used to replace clonidine, the course of β-blocker treatment should be started a few days after stopping taking clonidine.

Keep sealed.
