Evaluation of a new oral beta2-adrenoceptor stimulant bronchodilator, terbutaline
Abstract:
A double-blind crossover comparison was made of the effect of orally administered terbutaline (a new adrenergic drug with major action on beta2-receptors), ephedrine, and placebo in 15 patients with obstructive airways disease. Serial determination of ventilatory tests, arterial gas tensions, arterial blood pressure, ECG, blood chemistries, and urinalysis were made before and after administration of the tested drug. Terbutaline (5 mg) was found to be an effective bronchodilator with minimal side effects and an earlier onset and longer duration of action than ephedrine (25 mg).

Adrenergic Agonists: Therapeutic Classification
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
Adrenergic Agonists: Therapeutic Uses
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.

Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...
Antiasthma Drugs: Methylxanthines
Theophylline is thought to inhibit phosphodiesterase enzymes, increasing intracellular levels of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP). This rise in cAMP and cGMP concentrations stimulates cardiac function,...
