Xifamin Tablet 200 mg
Xifamin Tablet 200 mg Uses, Dosage, Side Effects, Food Interaction and all others data.
Xifamin Tablet 200 mg is a non-aminoglycoside semi-synthetic antibacterial derived from rifamycin SV. It inhibits bacterial RNA synthesis by binding to the bacterial DNA-dependent RNA polymerase and has antibacterial activity against Escherichia coli (E. coli).
Xifamin Tablet 200 mg is a structural analog of rifampin and a non-systemic, gastrointestinal site-specific antibiotic. This non-systemic property of the drug is due to the addition of a pyridoimidazole ring, which renders it non-absorbable. Xifamin Tablet 200 mg acts by inhibiting bacterial ribonucleic acid (RNA) synthesis and contributes to restore intestinal microflora imbalance. Other studies have also shown rifaximin to be an pregnane X receptor (PXR) activator. As PXR is responsible for inhibiting the proinflammatory transcription factor NF-kappa B (NF-κB) and is inhibited in inflammatory bowel disease (IBD), rifaximin was proven to be effective for the treatment of IBS-D.

Uses
Acute infectious diarrhoea including travelers diarrhoea, Diarrhoea predominant Irritable Bowel Syndrome (IBS-D), Hepatic Encephalopathy (H.E.)
Xifamin Tablet 200 mg is also used to associated treatment for these conditions: Bacterial Infections, Clostridium difficile infection recurrence, Hepatic Encephalopathy (HE), Irritable Bowel Syndrome (IBS), Traveler's Diarrhea
How Xifamin Tablet 200 mg works
Xifamin Tablet 200 mg acts by inhibiting RNA synthesis in susceptible bacteria by binding to the beta-subunit of bacterial deoxyribonucleic acid (DNA)-dependent ribonucleic acid (RNA) polymerase enzyme. This binding blocks translocation, which stops transcription.
Dosage
Xifamin Tablet 200 mg dosage
Acute Infectious Diarrhoea including Travelers’ Diarrhoea: 200 mg three times daily for 3 days.
Diarrhoea predominant Irritable Bowel Syndrome (IBS-D): 550 mg three times daily for 14 days.
Hepatic Encephalopathy (H.E.): 550 mg twice daily
Side Effects
Common side effects are nausea, vomiting, abdominal pain, flatulence, headache and dizziness.
Toxicity
LD50 > 2 g/kg (orally, in rats)
Precaution
Pregnancy and lactation. Caution in severe hepatic impairment (Child-Pugh class C). Not effective against diarrhoea caused by pathogen other than E. coli ; or diarrhoea complicated by fever and/or blood in the stool. Prolonged use may result in Clotridum difficile-associated diarrhoea. Severe hepatic impairment (Child-pugh class C).
Interaction
Although In vitro studies demonstrated the potential of Xifamin Tablet 200 mg to interact with cytochrome P450 (CYP3A4), a clinical drug-drug interaction study demonstrated that Xifamin Tablet 200 mg did not significantly affect the pharmacokinetics of midazolam. An additional clinical drug-drug interaction study showed no effect of Xifamin Tablet 200 mg on the presystemic metabolism of an oral contraceptive containing ethinyl estradiol and norgestimate. Therefore, clinical interactions with drugs metabolized by human cytochrome P450 isozymes are not expected.
Food Interaction
- Take with or without food. Fatty meals may increase the systemic AUC of rifaximin, but do not impact Cmax. Xifamin Tablet 200 mg is an antibacterial used for local action in the gastrointestinal tract; therefore, changes in systemic exposure may not significantly impact efficacy.
Xifamin Tablet 200 mg Drug Interaction
Unknown: aspirin, lorazepam, amoxicillin / clavulanate, diphenhydramine, duloxetine, metronidazole, furosemide, pregabalin, polyethylene glycol 3350, esomeprazole, acetaminophen, pantoprazole, acetaminophen, cyanocobalamin, ascorbic acid, cholecalciferol, alprazolam, ondansetron, sertraline, cetirizine
Xifamin Tablet 200 mg Disease Interaction
Elimination Route
Low absorption in both the fasting state and when administered within 30 minutes of a high-fat breakfast.
Half Life
Approximately 6 hours.
Elimination Route
In a mass balance study, after administration of 400 mg 14C-rifaximin orally to healthy volunteers, of the 96.94% total recovery, 96.62% of the administered radioactivity was recovered in feces almost exclusively as the unchanged drug and 0.32% was recovered in urine mostly as metabolites with 0.03% as the unchanged drug.Xifamin Tablet 200 mg accounted for 18% of radioactivity in plasma. This suggests that the absorbed rifaximin undergoes metabolism with minimal renal excretion of the unchanged drug
Pregnancy & Breastfeeding use
Pregnancy Category C. There are no adequate and well-controlled studies in pregnant women. Xifamin Tablet 200 mg should be used during pregnancy only if the potential benefit outweighs the potential risk to the fetus.
Use in Lactation: It is not known whether Xifamin Tablet 200 mg is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for adverse reactions in nursing infants from Xifamin Tablet 200 mg, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Contraindication
Xifamin Tablet 200 mg is contraindicated in patients with a hypersensitivity to Xifamin Tablet 200 mg, or any of the Rifamycin antimicrobial agents, or any of the components of Xifamin Tablet 200 mg.
Special Warning
Use in Children: The safety and effectiveness of Xifamin Tablet 200 mg 200 mg in pediatric patients with travelers’ diarrhoea less than 12 years of age have not established.The safety and effectiveness of Xifamin Tablet 200 mg 550 mg for hepatic encephalopathy have not been established in patients <18 years of age.
Use in geriatric patients: Clinical studies of Xifamin Tablet 200 mg tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects.
Use in Renal Insufficient Patients:The pharmacokinetics of Xifamin Tablet 200 mg in patients with impaired renal function has not been studied.
Use in Hepatic Insufficient Patients:No dosage adjustment with Xifamin Tablet 200 mg is necessary due to its limited systemic absorption. Nonetheless, caution should be exercised when Xifamin Tablet 200 mg is administered to patients with severe hepatic impairment.
Acute Overdose
