Interactions between your drugs

Minor

magnesium oxide vismodegib

Applies to: Prepopik (citric acid/magnesium oxide/sodium picosulfate) and vismodegib

The solubility of vismodegib is known to be pH-dependent (0.1 mcg/mL at pH 7 and 0.99 mg/mL at pH 1) and drugs that alter the pH of the upper gastrointestinal tract may affects its solubility and reduce its bioavailability. However, a clinically significant pharmacokinetic effect has not been observed, with results from a clinical study showing a 33% reduction in the unbound drug concentrations of vismodegib after 7 days of concomitant therapy with the proton pump inhibitor rabeprazole (20 mg, given 2 hours before each vismodegib administration).

Drug and food interactions

Moderate

sodium picosulfate food

Applies to: Prepopik (citric acid/magnesium oxide/sodium picosulfate)

ADJUST DOSING INTERVAL: Bowel cleansing products can increase the gastrointestinal transit rate. Oral medications administered within one hour of the start of administration of the bowel cleansing solution may be flushed from the gastrointestinal tract and not properly absorbed.

MANAGEMENT: Patients should be advised that absorption of oral medications may be impaired during bowel cleansing treatment. Oral medications (e.g., anticonvulsants, oral contraceptives, antidiabetic agents, antibiotics) should not be administered during and within one hour of starting bowel cleansing treatment whenever possible. However, if concomitant use cannot be avoided, monitoring for reduced therapeutic effects may be advisable.

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.
