एटेनोलोल और टरब्यूटालिन का इंटरैक्शन

Since beta 1 selectivity is not absolute, the lowest possible dose of TENORMIN should be used with therapy initiated at 50 mg and a beta 2 -stimulating agent (bronchodilator) should be made available.

In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.

Beta-Blockers Beta-adrenergic receptor blocking agents not only block the pulmonary effect of beta-agonists, such as terbutaline sulfate, but may produce severe bronchospasm in asthmatic patients.

Therefore, patients with asthma should not normally be treated with beta-blockers.

However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-adrenergic blocking agents in patients with asthma.
