Drug and Diluent Compatibilities

Because only limited data are available on the compatibility of Moxifloxacin-Actavis intravenous injection with other intravenous substances, additives or other medications should not be added to Moxifloxacin-Actavis Injection or infused simultaneously through the same intravenous line. If the same intravenous line or a Y-type line is used for sequential infusion of other drugs, or if the “piggyback” method of administration is used, the line should be flushed before and after infusion of Moxifloxacin-Actavis Injection with an infusion solution compatible with Moxifloxacin-Actavis Injection as well as with other drug(s) administered via this common line.

Compatible

Intravenous Solutions: Moxifloxacin-Actavis Injection is compatible with the following intravenous solutions at ratios from 1:10 to 10:1:

0.9% Sodium Chloride Injection, USP

1 Molar Sodium Chloride Injection

What other drugs will affect Moxifloxacin-Actavis?

Some medicines can make Moxifloxacin-Actavis much less effective when taken at the same time. If you take any of the following medicines, take your Moxifloxacin-Actavis dose 4 hours before or 8 hours after you take the other medicine:

• the ulcer medicine sucralfate, or antacids that contain calcium, magnesium, or aluminum (such as Maalox, Milk of Magnesia, Mylanta, Pepcid Complete, Rolaids, Tums, and others);

• didanosine (Videx) powder or chewable tablets;

• lanthanum carbonate or sevelamer; or

• vitamin or mineral supplements that contain aluminum, iron, magnesium, or zinc.

Tell your doctor about all your other medicines, especially:

• erythromycin;

• a blood thinner (warfarin, Coumadin, Jantoven);

• a diuretic or "water pill";

• heart rhythm medication;

• insulin or oral diabetes medicine (check your blood sugar regularly);

• medicine to treat depression or mental illness;

• steroid medicine (such as prednisone); or

• NSAIDs (nonsteroidal anti-inflammatory drugs)--aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.

This list is not complete. Other drugs may affect Moxifloxacin-Actavis, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.

Moxifloxacin-Actavis drug interactions (in more detail)

Moxifloxacin-Actavis interactions

Tablet: For the following substances, absence of a clinically relevant interaction with Moxifloxacin-Actavis was proven: Atenolol, ranitidine, calcium supplements, theophylline, oral contraceptives, glibenclamide, itraconazole, digoxin, morphine, probenecid. No dose adjustment is necessary for these drugs.

Antacids, Minerals and Multivitamins: Concomitant ingestion of Moxifloxacin-Actavis with antacids, minerals and multivitamins may result in impaired absorption of Moxifloxacin-Actavis after oral administration due to formation of chelate complexes with the multivalent cations contained in these preparations. This may lead to plasma concentrations considerably lower than desired. Hence, antacids, antiretroviral drugs (eg, didanosine) and other preparations containing magnesium or aluminium, sucralfate and agents containing iron or zinc should be administered at least 4 hours before or 2 hours after ingestion of an oral Moxifloxacin-Actavis dose.

Ranitidine: The concomitant administration with ranitidine did not change the absorption characteristics of Moxifloxacin-Actavis. Absorption parameters (C_max, t_max, AUC) were comparable, indicating absence of an influence of gastric pH on Moxifloxacin-Actavis uptake from the gastrointestinal tract.

Calcium Supplements: When given with high dose calcium supplements, only a slightly reduced rate of absorption was observed, while extent of absorption remained unaffected. The effect of high-dose calcium supplements on the absorption of Moxifloxacin-Actavis is considered as clinically not relevant.

Theophylline: In accordance with in vitro data, no influence of Moxifloxacin-Actavis on theophylline pharmacokinetics (and vice versa) at steady state was detected in humans, indicating that Moxifloxacin-Actavis does not interfere with the 1A2 subtypes of the CYP450 enzymes.

Warfarin: No interaction during concomitant treatment with warfarin on pharmacokinetics, prothrombin time and other coagulation parameters has been observed.

Changes in International Normalized Ratio (INR): Cases of increased anticoagulant activity have been reported in patients receiving anticoagulants concurrently with antibiotics, including Moxifloxacin-Actavis. The infectious disease (and its accompanying inflammatory process), age and general status of the patient are risk factors. Although an interaction between Moxifloxacin-Actavis and warfarin was not demonstrated in clinical trials, INR monitoring should be performed and, if necessary, the oral anticoagulant dosage should be adjusted as appropriate.

Oral Contraceptives:

Antidiabetics: No clinically relevant interaction was seen between glibenclamide and Moxifloxacin-Actavis.

Itraconazole: Exposure (AUC) to itraconazole was only marginally altered under concomitant Moxifloxacin-Actavis treatment. Pharmacokinetics of Moxifloxacin-Actavis were not significantly altered by itraconazole. No dose adjustment is necessary for itraconazole when given with Moxifloxacin-Actavis and vice versa.

Digoxin: The pharmacokinetics of digoxin are not significantly influenced by Moxifloxacin-Actavis (and vice versa). After repeated dosing in healthy volunteers, Moxifloxacin-Actavis increased C_max of digoxin by approximately 30% at steady state without affecting AUC or trough levels.

Morphine:

Parenteral administration of morphine with Moxifloxacin-Actavis did not reduce the oral bioavailability of Moxifloxacin-Actavis and only slighlty decreased C_max (17 %).

Atenolol: The pharmacokinetics of atenolol are not significantly altered by Moxifloxacin-Actavis. Following single dose administration in healthy subjects, AUC was marginally increased (by approximately 4%) and peak concentrations were decreased by 10%.

Probenecid: No significant effect on apparent total body clearance and renal clearance of Moxifloxacin-Actavis was found in a clinical study investigating the impact of probenecid on renal excretion.

Charcoal: Concomitant dosing of charcoal and oral Moxifloxacin-Actavis 400 mg reduced the systemic availability of the drug by >80% by preventing absorption in vivo. The application of activated charcoal in the early absorption phase prevents further increase of systemic exposure in cases of overdose.

After IV drug administration, carbo medicinalis only slightly reduces systemic exposure (approximately 20%).

Food and Dairy Products: Absorption of Moxifloxacin-Actavis was not altered by food intake (including dairy products). Moxifloxacin-Actavis can be taken independent from food intake.

Infusion: No interaction during concomitant treatment with warfarin, itraconazole, theophylline, digoxin and oral contraceptives.
