calcium carbonate patiromer

Applies to: aspirin / calcium carbonate and patiromer

GENERALLY AVOID: Coadministration with nonabsorbable cation-donating preparations such as antacids and laxatives may reduce the therapeutic effect of cation-exchange resins and increase the risk of systemic alkalosis. The proposed mechanism involves binding of the cation to the resin, which can interfere with the resin's potassium exchange capability and prevent the cation from neutralizing bicarbonate ions in the intestine. Concomitant use of sodium polystyrene sulfonate and antacids containing calcium, magnesium, and/or aluminum has been reported to cause metabolic alkalosis in patients with end-stage renal disease and advanced stages of chronic kidney disease. Theoretically, the interaction may also occur with other cation-exchange resins that possess nonspecific cation-binding capabilities such as calcium polystyrene sulfonate or patiromer. Other serious adverse effects have also been reported. One patient with chronic hypocalcemia of renal failure developed alkalosis and grand mal seizure when given sodium polystyrene sulfonate with magnesium hydroxide as a laxative. Intestinal obstruction due to concretions of aluminum hydroxide has occurred in combination with sodium polystyrene sulfonate and morphine.

MANAGEMENT: Nonabsorbable calcium, magnesium, or aluminum preparations such as antacids and laxatives should generally be avoided in patients receiving oral cation-exchange resins.

aspirin calcium carbonate

Applies to: aspirin / calcium carbonate and aspirin / calcium carbonate

MONITOR: Chronic administration of antacids may reduce serum salicylate concentrations in patients receiving large doses of aspirin or other salicylates. The mechanism involves reduction in salicylate renal tubular reabsorption due to urinary alkalinization by antacids, resulting in increased renal salicylate clearance. In three children treated with large doses of aspirin for rheumatic fever, serum salicylate levels declined 30% to 70% during coadministration with a magnesium and aluminum hydroxide antacid. Other studies have found similar, albeit less dramatic results. Antacids reportedly have no effect on the oral bioavailability of aspirin in healthy adults. However, administration of antacids containing either aluminum and magnesium hydroxide or calcium carbonate two hours before aspirin dosing led to reduced absorption of aspirin in uremic patients.

MANAGEMENT: Patients treated chronically with antacids (or oral medications that contain antacids such as didanosine buffered tablets or pediatric oral solution) and large doses of salicylates (i.e. 3 g/day or more) should be monitored for potentially diminished or inadequate analgesic and anti-inflammatory effects, and the salicylate dosage adjusted if necessary.

Drug and food interactions

Moderate

calcium carbonate food

Applies to: aspirin / calcium carbonate

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.

patiromer food

Applies to: patiromer

ADJUST DOSING INTERVAL: Patiromer can bind to some orally administered drugs, which may decrease their gastrointestinal absorption and reduce their effectiveness. According to the manufacturer, out of 28 drugs that were tested in in vitro binding studies, 14 did not show an interaction with patiromer (acetylsalicylic acid, allopurinol, amoxicillin, apixaban, atorvastatin, cephalexin, digoxin, glipizide, lisinopril, phenytoin, riboflavin, rivaroxaban, spironolactone, and valsartan). Twelve of the 14 drugs that did show an in vitro interaction were subsequently tested in in vivo studies with healthy volunteers, which revealed no changes in systemic exposure when coadministered with patiromer (amlodipine, cinacalcet, clopidogrel, furosemide, lithium, metoprolol, trimethoprim, verapamil, and warfarin). Patiromer was found to decrease systemic exposure of coadministered ciprofloxacin, levothyroxine, and metformin. However, no significant interaction occurred when patiromer and these drugs were dosed 3 hours apart.

MANAGEMENT: Patiromer should be administered with food at least 3 hours before or 3 hours after other oral medications. Alternatives to patiromer or the other medications should be considered if adequate dosing separation is not possible. Otherwise, clinical response and/or blood levels should be monitored where possible.

aspirin food

Applies to: aspirin / calcium carbonate

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

Applies to: aspirin / calcium carbonate

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

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.
