Question

Clinical indications for the use of adrenergic drugs stem mainly from their effects on the heart, blood vessels, and bronchi. They are often used as emergency drugs. For which of the following conditions would these drugs be used? Choose all that apply.
Myocardial infarction
Asthma attack
Anaphylaxis T/F

Answer 1

Answer: Adrenergic drugs are used both in the emergency treatment of Myocardial infarction, Asthma attack and Anaphylaxis T/F.

Explanation:

Andrenergic drugs acts by blocking renin release,and interfers with synthesis and release of Nor-epinephrine (Nor-adrenaline) thereby helping to reduce the peripheral vascular resistance and lowering the blood pressure.example; Methyldopa.

As a bronchodilator in asthma attack, Adrenergic drugs relax bronchial muscle spasm then dilate the bronchial trees thereby allowing proper ventilation of the lungs example: Aminophylline

Adrenergic drugs like epinephrine are used in anaphylaxis/ allergic reactions as well as hypersensitivity reactions to inhibit the action of histamines and as such relieve allergic reactions.
