Our highest priority is to raise awareness and to provide support for this illness. FDA Drug Safety Information for Patients and Health Care Professionals. Medical foods provide specific nutrients needed to manage ongoing problems with loose or frequent stools (diarrhea). In a study, patients with IBS who had loose or frequent stools were given Entera. Gam. The study showed that patients who took Entera. Gam. Some patients have developed serious bowel side effects while taking LOTRONEX. LOTRONEX may be right for you if all of these things are true about you. Your doctor has told you that your symptoms are due to IBS. A Co- pay Assistance Savings Program for LOTRONEX. Patients may be retreated up to 2 times if symptoms come back. If you know you have a bowel obstruction, do not take AMITIZA. ZELNORM is no longer approved for IBS- C or chronic constipation. Those interested may contact FDA’s Division for Drug Information about the emergency IND process at druginfo@fda. Resotran was approved for Chronic Idiopathic Constipation in women in Canada. Antidepressants are, therefore, effective in treating symptoms of IBS and other functional GI disorders. Patients who have taken antidepressants for their IBS symptoms have reported significant improvement in their abdominal pain and reduction in other IBS symptoms, such as diarrhea, constipation, bloating, nausea or urgency. Patients who have been taking antidepressants should be aware of the possibility of developing Antidepressant Discontinuation Syndrome, or SSRI Discontinuation Syndrome, upon rapid stopping or tapering the use of antidepressants. Antispasmodics and Antidiarrheals are helpful in reducing periodic painful episodes of spasms and diarrhea respectively. A specific regiment of antibiotics, namely Xifaxan (rifaximin), have been investigated and approved by the FDA to treat this IBS- D in the United States. Probiotics offer a way to restore the natural balance of your digestive system especially if you suffer from anyone of constipation, diarrhea, abdominal discomfort, urgency or gas and bloating.

To reduce the development of drug- resistant bacteria and maintain the effectiveness of Xifaxan and other antibacterial drugs, Xifaxan when used to treat infection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Travelers’ Diarrhea. Xifaxan is indicated for the treatment of travelers’ diarrhea (TD) caused by noninvasive strains of Escherichia coli in adults and pediatric patients 1. Limitations of Use. Xifaxan should not be used in patients with diarrhea complicated by fever or blood in the stool or diarrhea due to pathogens other than Escherichia coli . Differences in the treatment effect of those patients not using lactulose concomitantly could not be assessed. Xifaxan has not been studied in patients with MELD (Model for End- Stage Liver Disease) scores > 2. MELD scores over 1. There is increased systemic exposure in patients with more severe hepatic dysfunction . Patients who experience a recurrence of symptoms can be retreated up to two times with the same dosage regimen. Administration. Xifaxan can be taken with or without food . Hypersensitivity reactions have included exfoliative dermatitis, angioneurotic edema, and anaphylaxis . The effectiveness of Xifaxan in travelers’ diarrhea caused by Shigella spp. Xifaxan should not be used in patients where Campylobacter jejuni, Shigella spp., or Salmonella spp. Treatment with antibacterial agents alters the normal flora of the colon which may lead to overgrowth of C. Hypertoxin producing strains of C. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. The clinical trials were limited to patients with MELD scores < 2. Therefore, caution should be exercised when administering Xifaxan to patients with severe hepatic impairment (Child- Pugh Class C) . Caution should be exercised when concomitant use of Xifaxan and a P- glycoprotein inhibitor such as cyclosporine is needed. In patients with hepatic impairment, a potential additive effect of reduced metabolism and concomitant P- glycoprotein inhibitors may further increase the systemic exposure to rifaximin . The population studied had a mean age of 3. The adverse reactions leading to discontinuation were taste loss, dysentery, weight decrease, anorexia, nausea and nasal passage irritation. The adverse reaction that occurred at a frequency . The safety of Xifaxan 5. The population studied had a mean age of 5. Ninety- one percent of patients in the trial were taking lactulose concomitantly. The most common adverse reactions that occurred at an incidence . Across the 3 studies, 9. Xifaxan. In Trials 1 and 2, 6. Trial 3 evaluated the safety of Xifaxan in 3. The combined population studied had a mean age of 4. Because these reactions are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These reactions have been chosen for inclusion due to either their seriousness, frequency of reporting or causal connection to Xifaxan. Infections and Infestations. Cases of C. These events occurred as early as within 1. Drug Interactions. Effects of Xifaxan on Other Drugs. Substrates of Cytochrome P4. Rifaximin is not expected to inhibit cytochrome P4. A2, 2. A6, 2. B6, 2. C9, 2. C1. 9, 2. D6, 2. E1 and CYP3. A4 in clinical use based on in vitro studies . However, in patients with normal liver function, Xifaxan at the recommended dosing regimen is not expected to induce CYP3. A4. It is unknown whether rifaximin can have a significant effect on the pharmacokinetics of concomitant CYP3. A4 substrates in patients with reduced liver function who have elevated rifaximin concentrations. Effects of Other Drugs on Xifaxan. In vitro studies suggested that rifaximin is a substrate of P- glycoprotein, OATP1. A2, OATP1. B1 and OATP1. B3. Concomitant cyclosporine, an inhibitor of P- glycoprotein and OATPs, significantly increased the systemic exposure to rifaximin. Cyclosporine. Co- administration of cyclosporine, with Xifaxan resulted in 8. Cmax and AUC. The clinical significance of this increase in systemic exposure is unknown . Teratogenic effects were observed in animal reproduction studies following administration of rifaximin to pregnant rats and rabbits during organogenesis at doses approximately 0. In rabbits, ocular, oral and maxillofacial, cardiac, and lumbar spine malformations were observed. Ocular malformations were observed in both rats and rabbits at doses that caused reduced maternal body weight gain . Advise pregnant women of the potential risk to a fetus. Data. Animal Data. Rifaximin was teratogenic in rats at doses of 1. TD . Rifaximin was teratogenic in rabbits at doses of 6. TD . These effects include cleft palate, agnathia, jaw shortening, hemorrhage, eye partially open, small eyes, brachygnathia, incomplete ossification, and increased thoracolumbar vertebrae. A pre and postnatal development study in rats showed no evidence of any adverse effect on pre and postnatal development at oral doses of rifaximin up to 3. TD . The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for Xifaxan and any potential adverse effects on the breastfed infant from Xifaxan or from the underlying maternal condition. Pediatric Use. The safety and effectiveness of Xifaxan has not been established in pediatric patients less than 1. TD or in patients less than 1. HE and IBS- D. Geriatric Use. Of the total number of patients in the clinical study of Xifaxan for HE, 1. In the clinical studies of IBS- D, 1. No overall differences in safety or effectiveness were observed between these subjects and younger subjects for either indication. Clinical studies with Xifaxan for TD did not include sufficient numbers of patients aged 6. Other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Renal Impairment. The pharmacokinetics of rifaximin in patients with impaired renal function has not been studied. Hepatic Impairment. Following administration of Xifaxan 5. AUC. No dosage adjustment is recommended because rifaximin is presumably acting locally. Nonetheless, caution should be exercised when Xifaxan is administered to patients with severe hepatic impairment . In clinical studies at doses higher than the recommended dose (greater than 6. TD, greater than 1. HE or greater than 1. IBS- D), adverse reactions were similar in subjects who received doses higher than the recommended dose and placebo. In the case of overdosage, discontinue Xifaxan, treat symptomatically, and institute supportive measures as required. Xifaxan Description. Xifaxan tablets contain rifaximin, a non- aminoglycoside semi- synthetic, nonsystemic antibiotic derived from rifamycin SV. Rifaximin is a structural analog of rifampin. The chemical name for rifaximin is (2. S,1. 6Z,1. 8E,2. 0S,2. S,2. 2R,2. 3R,2. 4R,2. S,2. 6S,2. 7S,2. 8E)- 5,6,2. The empirical formula is C4. H5. 1N3. O1. 1 and its molecular weight is 7. The chemical structure is represented below: Xifaxan tablets for oral administration are film- coated and contain 2. Inactive ingredients: Each 2. Each 5. 50 mg tablet contains colloidal silicon dioxide, glycerol palmitostearate, microcrystalline cellulose, polyethylene glycol/macrogol, polyvinyl alcohol, red iron oxide, sodium starch glycolate, talc, and titanium dioxide. Xifaxan - Clinical Pharmacology. Mechanism of Action. Rifaximin is an antibacterial drug . Rifaximin plasma concentrations and exposures were low and variable. There was no evidence of accumulation of rifaximin following repeated administration for 3 days (9 doses). Peak plasma rifaximin concentrations after 3 and 9 consecutive doses ranged from 0. L on Day 1 and 0. L on Day 3. Similarly, AUC0- last estimates were 6. Xifaxan is not suitable for treating systemic bacterial infections because of limited systemic exposure after oral administration . Among patients with a history of HE, the mean AUC in patients with Child- Pugh Class C hepatic impairment was 2- fold higher than in patients with Child- Pugh Class A hepatic impairment . After multiple doses, AUCtau was 1. Day 1 in IBS- D patients (Table 2). Table 2. In vivo, the mean protein binding ratio was 6. Xifaxan was administered. Elimination. The mean half- life of rifaximin in healthy subjects at steady- state was 5. IBS- D patients. Metabolism: In an in vitro study rifaximin was metabolized mainly by CYP3. A4. Rifaximin accounted for 1. Excretion: In a mass balance study, after administration of 4. C- rifaximin orally to healthy volunteers, of the 9. Biliary excretion of rifaximin was suggested by a separate study in which rifaximin was detected in the bile after cholecystectomy in patients with intact gastrointestinal mucosa. Specific Populations. Hepatic Impairment. The systemic exposure of rifaximin was markedly elevated in patients with hepatic impairment compared to healthy subjects. The pharmacokinetics of rifaximin in patients with a history of HE was evaluated after administration of Xifaxan 5. The pharmacokinetic parameters were associated with a high variability and mean rifaximin exposure (AUC. The mean AUC. Rifaximin is not a substrate of OATP2. B1. Cyclosporine. In vitro in the presence of P- glycoprotein inhibitor, verapamil, the efflux ratio of rifaximin was reduced greater than 5.
