What is the prescription for DuoNeb (ipratropium bromide and albuterol sulfate)?

From the Guidelines

The standard prescription for DuoNeb (ipratropium bromide and albuterol sulfate) is to administer one unit dose (3 mL) via nebulizer every 20 minutes for 3 doses then as needed. This is based on the guidelines from the expert panel report 3 (epr-3): guidelines for the diagnosis and management of asthma-summary report 2007 1. The medication contains 0.5 mg ipratropium bromide and 2.5 mg albuterol in each 3-mL vial. Key points to consider when prescribing DuoNeb include:

• The combination of ipratropium bromide and albuterol sulfate provides complementary mechanisms of action, with albuterol acting as a beta-2 agonist to relax airway smooth muscle and ipratropium acting as an anticholinergic to block acetylcholine receptors and reduce mucus secretion.
• The medication may be used for up to 3 hours in the initial management of severe exacerbations, but the addition of ipratropium to albuterol has not been shown to provide further benefit once the patient is hospitalized 1.
• When writing the prescription, it is essential to include the patient's full name, date of birth, the medication name "DuoNeb (ipratropium-albuterol) 0.5 mg-2.5 mg/3 mL solution," quantity, dosing instructions, and the prescriber's signature with DEA number. Some important considerations for the prescription include:
• Quantity: typically 30-60 unit doses
• Refills: 3-5 refills, lasting 1-2 months depending on usage frequency
• Dosing instructions: one unit dose (3 mL) via nebulizer every 20 minutes for 3 doses then as needed.

From the FDA Drug Label

DOSAGE AND ADMINISTRATION The usual dosage of ipratropium bromide inhalation solution is 500 mcg (1 Unit-Dose Vial) administered three to four times a day by oral nebulization, with doses 6 to 8 hours apart. Ipratropium bromide inhalation solution can be mixed in the nebulizer with albuterol or metaproterenol if used within one hour.

The prescription for DuoNeb (ipratropium bromide and albuterol sulfate) is 500 mcg of ipratropium bromide administered three to four times a day by oral nebulization, with doses 6 to 8 hours apart, and it can be mixed with albuterol in the nebulizer if used within one hour 2.

From the Research

Prescription for DuoNeb

The prescription for DuoNeb, a combination of ipratropium bromide and albuterol sulfate, is typically as follows:

• 3 mL of the solution via nebulizer three to four times daily 3, 4
• Each 3 mL dose contains 0.5 mg of ipratropium bromide and 2.5 mg (or 3.0 mg in some cases) of albuterol sulfate 4, 5
• Patients may use up to two extra doses of study medication daily for control of symptoms on an as-needed basis 4

Administration

The combination of ipratropium bromide and albuterol sulfate can be administered using a small-volume nebulizer (SVN) or a metered-dose inhaler (MDI) 6, 4

• SVN: 3 mL of the solution three times daily 4
• MDI: 2 actuations (containing 26 mcg of ipratropium bromide and 206 mcg of albuterol sulfate) four times daily 3

Key Points

• The combination of ipratropium bromide and albuterol sulfate provides better bronchodilation than either agent alone in patients with COPD 6, 4
• The combination therapy simplifies treatment and improves compliance compared to individual components 5
