Minor

moricizine oxtriphylline

Applies to: moricizine and Choledyl (oxtriphylline)

Moricizine may increase the plasma clearance of theophylline by 46% to 68% and decrease theophylline half-life by 20% to 34%. Decreased plasma theophylline levels may result. Conversely, theophylline toxicity may occur when moricizine is discontinued. The mechanism is unknown, but may be related to hepatic enzyme induction. Management consists of monitoring the patient for theophylline efficacy, checking levels if indicated, and adjusting theophylline dosage accordingly. Patients should be advised to notify their physician if they experience a worsening of their respiratory symptoms.

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.
