Bronchodilator stimulate ____
|
|
Alpha 1 receptor
|
|
|
Alpha 2 receptor
|
|
|
Beta 1 receptor
|
|
|
Beta 2 receptor
|
Explanation:
Detailed explanation-1: -Stimulation of beta-2 receptors in the lungs causes bronchodilation, the desired clinical effect. Albuterol has been used in humans to inhibit uterine contractions during premature labor. Stim-ulation of beta-2 receptors on skeletal muscle cells causes increased contractility and may lead to muscle tremors.
Detailed explanation-2: -Beta2-agonists (bronchodilators) are a group of drugs prescribed to treat asthma. Short-acting beta-agonists (SABAs) provide quick relief of asthma symptoms.
Detailed explanation-3: -Beta2-agonists relax airway smooth muscle by stimulating beta2-adrenergic receptors, which increases cyclic AMP and antagonizes mechanisms of bronchoconstriction.
