Dược Lực Học :
Isoetharine is a relatively selective beta2-adrenergic bronchodilator. Isoetharine is indicated for the relief of bronchospasm associated with chronic obstructive pulmonary disease. Adrenergic bronchodilators are breathed in through the mouth to open up the bronchial tubes (air passages) of the lungs.
Cơ Chế Tác Dụng :
Isoetarine is a selective adrenergic beta-2 agonist used as fast acting bronchodilator for emphysema, bronchitis and asthma. [PubChem]
The pharmacologic effects of isoetharine are attributable to stimulation through beta-adrenergic receptors of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic AMP. Increased cyclic AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.
Độc Tính :
Signs of overdose include tachycardia, palpitations, nausea, headache, and epinephrine-like side effects.
Chỉ Định :
For the treatment of asthma, wheezing, and chronic asthmatic bronchitis.
Tương Tác Thuốc :
