Midazolam HCl has been shown to be incompatible with Y-site administration of Rifun 20mg I.V. for Injection. Rifun 20mg I.V. for Injection may not be compatible with products containing zinc. When Rifun 20mg I.V. for Injection is administered through a Y-site, immediately stop use if precipitation or discoloration occurs.
Gastroesophageal Reflux Disease Associated With a History of Erosive Esophagitis
Recommended Dosage
The recommended adult dose is 40 mg Rifun 20mg given once daily by intravenous infusion for 7 to 10 days.
Treatment with Rifun 20mg® I.V. (Rifun 20mg sodium) for Injection should be discontinued as soon as the patient is able to receive treatment with Rifun 20mg Delayed-Release Tablets or
Oral Suspension.
Administration and Preparation Instructions
Data on the safe and effective dosing for conditions other than those described such as life-threatening upper gastrointestinal bleeds, are not available. Rifun 20mg I.V. 40 mg once daily does not raise gastric pH to levels sufficient to contribute to the treatment of such life-threatening conditions.
Fifteen Minute Infusion
Rifun 20mg I.V. for Injection should be reconstituted with 10 mL of 0.9% Sodium Chloride Injection, USP, and further diluted (admixed) with 100 mL of 5% Dextrose Injection, USP, 0.9% Sodium Chloride Injection, USP, or Lactated Ringer's Injection, USP, to a final concentration of approximately 0.4 mg/mL. The reconstituted solution may be stored for up to 6 hours at room temperature prior to further dilution. The admixed solution may be stored at room temperature and must be used within 24 hours from the time of initial reconstitution. Both the reconstituted solution and the admixed solution do not need to be protected from light.
Rifun 20mg I.V. for Injection admixtures should be administered intravenously over a period of approximately 15 minutes at a rate of approximately 7 mL/min.
Two Minute Infusion
Rifun 20mg I.V. for Injection should be reconstituted with 10 mL of 0.9% Sodium Chloride Injection, USP, to a final concentration of approximately 4 mg/mL. The reconstituted solution may be stored for up to 24 hours at room temperature prior to intravenous infusion and does not need to be protected from light. Rifun 20mg I.V. for Injection should be administered intravenously over a period of at least 2 minutes.
Pathological Hypersecretion Including Zollinger-Ellison Syndrome
Recommended Dosage
The dosage of Rifun 20mg I.V. for Injection in patients with pathological hypersecretory conditions including Zollinger-Ellison Syndrome varies with individual patients. The recommended adult dosage is 80 mg intravenously every 12 hours. The frequency of dosing can be adjusted to individual patient needs based on acid output measurements. In those patients who need a higher dosage, 80 mg intravenously every 8 hours is expected to maintain acid output below 10 mEq/h. Daily doses higher than 240 mg or administered for more than 6 days have not been studied. Transition from oral to intravenous and from intravenous to oral formulations of gastric acid inhibitors should be performed in such a manner to ensure continuity of effect of suppression of acid secretion. Patients with Zollinger-Ellison Syndrome may be vulnerable to serious clinical complications of increased acid production even after a short period of loss of effective inhibition.
Administration and Preparation Instructions
Fifteen Minute Infusion
Each vial of Rifun 20mg I.V. for Injection should be reconstituted with 10 mL of 0.9% Sodium Chloride Injection, USP. The contents of the two vials should be combined and further diluted (admixed) with 80 mL of 5% Dextrose Injection, USP, 0.9% Sodium Chloride Injection, USP, or Lactated Ringer's Injection, USP, to a total volume of 100 mL with a final concentration of approximately 0.8 mg/mL. The reconstituted solution may be stored for up to 6 hours at room temperature prior to further dilution. The admixed solution may be stored at room temperature and must be used within 24 hours from the time of initial reconstitution. Both the reconstituted solution and the admixed solution do not need to be protected from light.
Rifun 20mg I.V. for Injection should be administered intravenously over a period of approximately 15 minutes at a rate of approximately 7 mL/min.
Two minute Infusion
Rifun 20mg I.V. for Injection should be reconstituted with 10 mL of 0.9% Sodium Chloride Injection, USP, per vial to a final concentration of approximately 4 mg/mL. The reconstituted solution may be stored for up to 24 hours at room temperature prior to intravenous infusion and does not need to be protected from light. The total volume from both vials should be administered intravenously over a period of at least 2 minutes.

Rifun 20mg interactions

What other drugs will affect Rifun 20mg?
Rifun 20mg is metabolized through the cytochrome P450 system, primarily the CYP2C19 and CYP3A4 isozymes, and subsequently undergoes Phase II conjugation.
Based on studies evaluating possible interactions of Rifun 20mg with other drugs, no dosage adjustment is needed with concomitant use of the following: theophylline, cisapride, antipyrine, caffeine, carbamazepine, diazepam (and its active metabolite, desmethyldiazepam), diclofenac, naproxen, piroxicam, digoxin, ethanol, glyburide, an oral contraceptive (levonorgestrel/ethinyl estradiol), metoprolol, nifedipine, phenytoin, warfarin, midazolam, clarithromycin, metronidazole, or amoxicillin. Clinically relevant interactions of Rifun 20mg with other drugs with the same metabolic pathways are not expected. Therefore, when coadministered with Rifun 20mg, adjustment of the dosage of Rifun 20mg or of such drugs may not be necessary. There was also no interaction with concomitantly administered antacids. There have been postmarketing reports of increased INR and prothrombin time in patients receiving proton pump inhibitors, including Rifun 20mg, and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Patients treated with proton pump inhibitors and warfarin concomitantly should be monitored for increases in INR and prothrombin time.
Because of profound and long lasting inhibition of gastric acid secretion, Rifun 20mg may interfere with absorption of drugs where gastric pH is an important determinant of their bioavailability (eg, ketoconazole, ampicillin esters, and iron salts).
Laboratory Tests
There have been reports of false-positive urine screening tests for tetrahydrocannabinol (THC) in patients receiving most proton pump inhibitors, including Rifun 20mg. An alternative confirmatory method should be considered to verify positive results.
