Interactions between your drugs

Major

famotidine dasatinib

Applies to: Acid Controller Complete (calcium carbonate / famotidine / magnesium hydroxide) and dasatinib

GENERALLY AVOID: Nonclinical data indicate that the solubility of dasatinib is pH-dependent. Therefore, long-term suppression of gastric acid secretion by H2-receptor antagonists or inhibitors of the proton pump (PPIs or potassium-competitive acid blockers [PCABs]) is likely to reduce dasatinib systemic exposure. In 24 healthy study subjects, administration of a 50 mg dose of dasatinib 10 hours after famotidine was associated with an approximately 60% reduction in dasatinib peak plasma concentration (Cmax) and systemic exposure (AUC). In 14 healthy study subjects, administration of a single 100 mg dose of dasatinib 22 hours following a 40 mg dose of omeprazole at steady state reduced the Cmax and AUC of dasatinib by over 40% each.

MANAGEMENT: Concomitant use of dasatinib with H2-receptor antagonists or inhibitors of the proton pump is not recommended. If gastric acidity management is necessary, antacids should be considered in place of these agents. However, patients treated with dasatinib should avoid taking antacids or oral medications that contain antacids (e.g., didanosine buffered tablets or pediatric oral solution) for at least two hours before and two hours after administration of dasatinib.

calcium carbonate dasatinib

Applies to: Acid Controller Complete (calcium carbonate / famotidine / magnesium hydroxide) and dasatinib

ADJUST DOSING INTERVAL: Nonclinical data indicate that the solubility of dasatinib is pH-dependent. Therefore, coadministration with antacids or agents with acid-neutralizing effects may reduce the oral bioavailability of dasatinib. In a pharmacokinetic study of 24 healthy subjects, administration of a 50 mg dose of dasatinib with 30 mL of aluminum hydroxide/magnesium hydroxide was associated with a 55% reduction in systemic exposure (AUC) and a 58% reduction in peak plasma concentration (Cmax) of dasatinib. However, when the same dose of aluminum hydroxide/magnesium hydroxide was administered two hours prior to the dasatinib dose, there was no significant change in dasatinib systemic exposure (AUC), and the dasatinib Cmax was increased 26%.

MANAGEMENT: Patients treated with dasatinib should avoid taking antacids or oral medications that contain antacids (e.g., didanosine buffered tablets or paediatric oral solution) for at least two hours before and two hours after administration of dasatinib.

famotidine calcium carbonate

Applies to: Acid Controller Complete (calcium carbonate / famotidine / magnesium hydroxide) and Acid Controller Complete (calcium carbonate / famotidine / magnesium hydroxide)

Antacids and some aluminum, calcium, and magnesium salts may decrease the plasma concentrations of H2-receptor antagonists during oral coadministration. The mechanism of interaction is unknown, but may involve reduced oral absorption due to increased gastric pH. Study data vary, with no changes to nearly 60% reductions in systemic exposures (AUCs) reported for cimetidine, famotidine, and ranitidine. The clinical significance has not been established. As a precaution, patients may consider taking H2-receptor antagonists one to two hours before antacids.

Drug and food interactions

Major

dasatinib food

Applies to: dasatinib

GENERALLY AVOID: Grapefruit and grapefruit juice may significantly increase the plasma concentrations of dasatinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall induced by certain compounds present in grapefruit. Because grapefruit juice inhibits primarily intestinal rather than hepatic CYP450 3A4, the magnitude of interaction is greatest for those drugs that undergo significant presystemic metabolism by CYP450 3A4 (i.e., drugs with low oral bioavailability). In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict. Because dasatinib prolongs the QT interval, high plasma levels of dasatinib may increase the risk of ventricular arrhythmias such as torsade de pointes and sudden death.

MANAGEMENT: Patients treated with dasatinib should avoid consumption of grapefruit, grapefruit juice, and any supplement containing grapefruit extract. Some authorities recommend close monitoring for toxicity (e.g., myelosuppression, bleeding complications, fluid retention, bradycardia or other conduction disturbances) and a reduction of dasatinib dosage to a range of 20 to 40 mg daily should be considered if there are no alternatives and concomitant use with a potent CYP450 3A4 inhibitor is necessary.

calcium carbonate food

Applies to: Acid Controller Complete (calcium carbonate / famotidine / magnesium hydroxide)

ADJUST DOSING INTERVAL: Administration with food may increase the absorption of calcium. However, foods high in oxalic acid (spinach or rhubarb), or phytic acid (bran and whole grains) may decrease calcium absorption.

MANAGEMENT: Calcium may be administered with food to increase absorption. Consider withholding calcium administration for at least 2 hours before or after consuming foods high in oxalic acid or phytic acid.

famotidine food

Applies to: Acid Controller Complete (calcium carbonate / famotidine / magnesium hydroxide)

H2 antagonists may reduce the clearance of nicotine. Cimetidine, 600 mg given twice a day for two days, reduced clearance of an intravenous nicotine dose by 30%. Ranitidine, 300 mg given twice a day for two days, reduced clearance by 10%. The clinical significance of this interaction is not known. Patients should be monitored for increased nicotine effects when using the patches or gum for smoking cessation and dosage adjustments should be made as appropriate.

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.
