Abstract:
Benzalkonium chloride (BAC) added to nebulized albuterol may induce bronchospasm. The objective of this study was to determine the availability of BAC-containing nebulized albuterol in the Bronx, New York pharmacies. A cross-sectional telephone survey of pharmacies was conducted. Overall, 158 (80%) pharmacies participated in the survey; 133 (84%) carried BAC-containing albuterol; 25 (16%) dispensed BAC-containing albuterol solution when presented with a prescription written for generic albuterol. Only 14 (9%) pharmacists had seen a prescription for nebulized albuterol where a physician specified "without BAC." Despite availability of BAC-free albuterol, pharmacies in the Bronx still carried and dispensed BAC-containing product.

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: Inhaled Corticosteroids and Glucocorticoids
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
