BID is a common frequency order for which of the following respiratory medications?

BID stands for "twice daily," which is a common dosing frequency for several respiratory medications, particularly inhaled corticosteroids and some long-acting agents. Flovent, which contains the active ingredient fluticasone propionate, is an inhaled corticosteroid used for the management of persistent asthma and chronic obstructive pulmonary disease (COPD). Administering Flovent twice daily helps maintain effective control of airway inflammation, making it appropriate for chronic use.

While other medications mentioned may have different dosing schedules, Flovent's recommended usage aligns well with the BID frequency to ensure steady plasma levels of the medication, contributing to its efficacy in reducing asthma attacks or exacerbations in patients with chronic respiratory conditions. This consistent dosing is vital for chronic management rather than as a rescue or acute treatment, which differentiates it from medications used more sporadically.
