ciprofloxacin quiNIDine

Applies to: Proquin XR (ciprofloxacin) and Quinidex Extentabs (quinidine)

CONTRAINDICATED: Quinolones such as ciprofloxacin, gatifloxacin, gemifloxacin, levofloxacin, lomefloxacin, moxifloxacin, norfloxacin, ofloxacin, and sparfloxacin may cause dose-related prolongation of the QT interval in some patients. Coadministration with other agents that can prolong the QT interval may result in elevated risk of ventricular arrhythmias, including ventricular tachycardia and torsade de pointes, because of additive arrhythmogenic potential related to their effects on cardiac conduction. Torsade de pointes have been reported in a few patients receiving sparfloxacin alone and with antiarrhythmic agents like amiodarone and disopyramide. There have also been isolated case reports of clinically significant interactions with sotalol, a class III antiarrhythmic agent, for both gatifloxacin and moxifloxacin. Ciprofloxacin, levofloxacin, lomefloxacin, norfloxacin, and ofloxacin alone have been associated with extremely rare cases of torsade de pointes and ventricular tachycardia.

MANAGEMENT: Product labeling for certain quinolones recommends avoiding concomitant therapy with class IA (e.g., disopyramide, quinidine, procainamide) and class III (e.g., amiodarone, dofetilide, ibutilide, sotalol) antiarrhythmic agents, as well as bepridil.

ciprofloxacin food

Applies to: Proquin XR (ciprofloxacin)

ADJUST DOSING INTERVAL: Concurrent ingestion of dairy products (milk, yogurt) or calcium-fortified foods (i.e., cereal, orange juice) may decrease the activity of certain oral fluoroquinolone antibiotics. The mechanism is chelation of calcium and the quinolone, resulting in decreased bioavailability. In the case of orange juice, inhibition of intestinal transport mechanisms (P-glycoprotein or organic anion-transporting polypeptides) by flavones may also be involved. One study reported an average 41% decrease in maximum plasma concentrations and a 38% decrease in AUC when ciprofloxacin was given with calcium-fortified orange juice instead of water. Administration of ciprofloxacin tablets with enteral nutrition may reduce its bioavailability and maximum serum concentrations. Data have been conflicting and variable by the type of enteral nutrition product, location of the feeding tube, and patient characteristics. Decreased absorption is expected if ciprofloxacin is given by jejunostomy tube.

MANAGEMENT: Oral ciprofloxacin should not be taken with dairy products or calcium-fortified foods alone, but may be taken with meals that contain these products. When taken alone, dairy products or calcium-fortified foods should be ingested at least 2 hours before or after ciprofloxacin administration. When ciprofloxacin tablets are administered to patients receiving continuous enteral nutrition, some experts recommend that the tube feeding should be interrupted for at least 1 hour before and 2 hours after the dose of ciprofloxacin is given. Patients should be monitored for altered antimicrobial efficacy and switched to intravenous ciprofloxacin if necessary. If no enteral route besides a jejunostomy tube is available, it is also recommended to switch to intravenous ciprofloxacin. According to the manufacturer, ciprofloxacin oral suspension should not be administered via nasogastric or feeding tubes due to its physical characteristics.

quiNIDine food

Applies to: Quinidex Extentabs (quinidine)

GENERALLY AVOID: In a small, randomized, crossover study, the administration of quinidine with grapefruit juice (compared to water) to healthy volunteers significantly prolonged the time to reach peak plasma quinidine concentrations and decreased the plasma concentrations of its major metabolite, 3-hydroxyquinidine. These changes were associated pharmacodynamically with both a delay and a reduction in the maximal effect on QTc interval. The proposed mechanism is delay of gastric emptying as well as inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall induced by certain compounds present in grapefruits.

MANAGEMENT: Given the drug's narrow therapeutic index, patients receiving quinidine therapy should avoid the consumption of grapefruits and grapefruit juice to prevent any undue fluctuations in plasma drug levels.

ciprofloxacin food

Applies to: Proquin XR (ciprofloxacin)

ADJUST DOSING INTERVAL: Oral preparations that contain magnesium, aluminum, or calcium may significantly decrease the gastrointestinal absorption of quinolone antibiotics. Absorption may also be reduced by sucralfate, which contains aluminum, as well as other polyvalent cations such as iron and zinc. The mechanism is chelation of quinolones by polyvalent cations, forming a complex that is poorly absorbed from the gastrointestinal tract. The bioavailability of ciprofloxacin has been reported to decrease by as much as 90% when administered with antacids containing aluminum or magnesium hydroxide.

MANAGEMENT: When coadministration cannot be avoided, quinolone antibiotics should be dosed either 2 to 4 hours before or 4 to 6 hours after polyvalent cation-containing products to minimize the potential for interaction. When coadministered with Suprep Bowel Prep (magnesium/potassium/sodium sulfates), the manufacturer recommends administering fluoroquinolone antibiotics at least 2 hours before and not less than 6 hours after Suprep Bowel Prep to avoid chelation with magnesium. Please consult individual product labeling for specific recommendations.

MONITOR: Coadministration with certain quinolones may increase the plasma concentrations and pharmacologic effects of caffeine due to inhibition of the CYP450 1A2 metabolism of caffeine. Quinolones that may inhibit CYP450 1A2 include ciprofloxacin, enoxacin, grepafloxacin, nalidixic acid, norfloxacin, pipemidic acid, and pefloxacin (not all commercially available). In healthy volunteers, enoxacin (100 to 400 mg twice daily) increased systemic exposure (AUC) of caffeine by 2- to 5-fold and reduced its clearance by approximately 80%. Pipemidic acid (400 to 800 mg twice daily) increased AUC of caffeine by 2- to 3-fold and reduced its clearance by approximately 60%. Ciprofloxacin (250 to 750 mg twice daily) increased AUC and elimination half-life of caffeine by 50% to over 100%, and reduced its clearance by 30% to 50%. Norfloxacin 400 mg twice daily increased caffeine AUC by 16%, while 800 mg twice daily increased caffeine AUC by 52% and reduced its clearance by 35%. Pefloxacin (400 mg twice daily) has been shown to reduce caffeine clearance by 47%.

MANAGEMENT: Patients using caffeine-containing products should be advised that increased adverse effects such as headache, tremor, restlessness, nervousness, insomnia, tachycardia, and blood pressure increases may occur during coadministration with quinolones that inhibit CYP450 1A2. Caffeine intake should be limited when taking high dosages of these quinolones. If an interaction is suspected, other quinolones such as gatifloxacin, gemifloxacin, levofloxacin, lomefloxacin, moxifloxacin, and ofloxacin may be considered, since they are generally believed to have little or no effect on CYP450 1A2 or have been shown not to interact with caffeine.

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.
