Minor

formoterol mometasone

Applies to: Dulera (formoterol / mometasone) and Dulera (formoterol / mometasone)

Although they are often combined in clinical practice, the concomitant use of beta-2 adrenergic agonists and corticosteroids may result in additive hypokalemic effects. Since beta-2 agonists can sometimes cause QT interval prolongation, the development of hypokalemia may potentiate the risk of ventricular arrhythmias including torsade de pointes. However, clinical data are limited, and the potential significance is unknown. Patients who are receiving systemic or nebulized formulations of beta-2 agonists, high dosages of inhaled beta-2 agonists, or systemic corticosteroid therapy may be at a greater risk of developing hypokalemia.

Drug and food interactions

Major

sodium oxybate food

Applies to: sodium oxybate

CONTRAINDICATED: Alcohol may potentiate the central nervous system and respiratory depressant effects of sodium oxybate, which is the sodium salt of gamma hydroxybutyrate (GHB). An increased risk of serious adverse reactions such as respiratory depression, hypotension, profound sedation, syncope, coma, and even death should be anticipated.

ADJUST DOSING INTERVAL: Food may delay the absorption and significantly decrease the bioavailability of sodium oxybate. When sodium oxybate was administered immediately after a high-fat meal, the time to reach peak plasma concentration (Tmax) increased from 0.75 hour to 2 hours, the peak plasma concentration (Cmax) decreased by a mean of 59%, and the systemic exposure (AUC) decreased by a mean of 37%.

MANAGEMENT: The concomitant use of sodium oxybate with alcohol is considered contraindicated. The first dose of sodium oxybate should be taken at least 2 hours after a meal to ensure maximal absorption.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
