In what forms does bitolterol come?

Bitolterol is a bronchodilator used primarily in the management of asthma and chronic obstructive pulmonary disease (COPD). The correct answer indicates that bitolterol is available in the forms of Metered-Dose Inhalers (MDI) and as an aerosol. These forms are specifically designed for inhalation, which allows the medication to act directly on the airways, providing rapid relief from bronchospasm.

MDIs are handheld devices that deliver a specific amount of medication to the lungs in aerosol form, making them very convenient for patients. The aerosol formulation allows for the fine mist to be inhaled deeply into the lungs, ensuring that the drug can exert its therapeutic effects effectively.

Other forms listed, such as tablets, injections, or powders, are not relevant for bitolterol, as they do not align with the medication's delivery system designed for managing respiratory conditions where fast action and targeted delivery are critical.
