Edit list (add/remove drugs)

Interactions between your drugs

Moderate

cevimeline atazanavir

Applies to: cevimeline and atazanavir

MONITOR: Coadministration with inhibitors of CYP450 2D6 and/or 3A4 may increase the plasma concentrations of cevimeline, which is metabolized by these isoenzymes.

MANAGEMENT: Dosage adjustments and clinical monitoring may be appropriate whenever a CYP450 2D6 and/or 3A4 inhibitor is added to or withdrawn from therapy. Patients should be advised to notify their physician if they experience excessive adverse cholinergic effects of cevimeline such as nausea, vomiting, diarrhea, sweating, salivation, urinary frequency, visual disturbance, confusion, tremor, palpitations, or irregular heartbeat.

Drug and food interactions

Moderate

atazanavir food

Applies to: atazanavir

ADJUST DOSING INTERVAL: Administration of atazanavir with food enhances oral bioavailability and reduces pharmacokinetic variability. According to the manufacturer, administration with a light meal increased the peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of a single 400 mg dose of atazanavir by 57% and 70%, respectively, relative to the fasting state. Administration with a high-fat meal resulted in a mean increase of 35% in atazanavir AUC and no change in Cmax compared to fasting. The coefficient of variation of AUC and Cmax decreased by approximately one-half when given with either a light or high-fat meal compared to the fasting state.

MANAGEMENT: To ensure maximal oral absorption, atazanavir should be administered with or immediately after a meal.

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.
