Cefuroxime (सेफ्यूरोक्साइम) Tablet — सम्पूर्ण क्लिनिकल गाइड
यह गाइड MBBS/MD स्तर के क्लिनिकल संदर्भ के लिए है — mechanism से लेकर रोग-विशेष indications, pathology test correlations, पूर्ण dosing tables (adult/child/renal/pregnancy), interactions, आहार-सुझाव, adverse effects और stewardship तक सब कवर करता है।
1. सार (Overview)
Cefuroxime β-lactam antibiotic है — 2nd generation cephalosporin। यह bactericidal होता है और bacterial cell-wall synthesis को inhibit करता है। फार्मास्युटिकल फॉर्म में tablet (250 mg, 500 mg), oral suspension और parenteral (IV/IM) उपलब्ध है (Cefuroxime axetil = oral prodrug; Cefuroxime sodium = parenteral)।
Pharmacology — संक्षेप
- Mechanism: PBPs (penicillin-binding proteins) से binding → peptidoglycan cross-linking blocked → bacterial lysis.
- Spectrum: Gram-positive cocci (staphylococci—not MRSA), Streptococci; Gram-negative rods (H. influenzae, Moraxella, Enterobacteriaceae subset), some β-lactamase producers.
- Pharmacokinetics: Cefuroxime axetil is absorbed orally (bioavailability increased with food), hydrolyzed to active cefuroxime. Renally excreted — dose adjust in renal impairment.
2. Mechanism of action & Resistance
Cefuroxime binds PBPs, PBP-1, PBP-2 — preventing final transpeptidation step of peptidoglycan synthesis. Resistance mechanisms include:
- β-lactamase production (extended spectrum β-lactamases — ESBLs confer resistance to many cephalosporins).
- PBP modification (e.g., in MRSA → cephalosporins ineffective).
- Efflux pumps and reduced permeability (Gram-negative outer membrane changes).
Clinical implication: culture & sensitivity (C/S) are essential for severe infections and when local resistance is suspected.
3. Indications — कब और किस बीमारी में उपयोग
नीचे सूची में minor और major indications दोनों दिए गए हैं; साथ में pathology background और सम्बंधित tests भी दिए हैं।
3.1 Respiratory tract infections
Indications: Community-acquired pneumonia (mild–moderate), acute exacerbation of chronic bronchitis, acute otitis media, sinusitis (selected cases).
Pathology: Bacterial invasion of airways/alveoli causing consolidation, inflammatory exudate; common organisms: Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis.
Tests: Chest X-ray (lobar consolidation), CBC (neutrophilia), sputum Gram-stain & culture, blood cultures (if severe), pulse oximetry, CRP/Procalcitonin as adjuncts.
3.2 Urinary Tract Infections (UTI)
Indications: Uncomplicated cystitis (selected), pyelonephritis (depending on severity & C/S).
Pathology: Ascending infection commonly E. coli; tissue invasion and inflammatory response in bladder/renal pelvis.
Tests: Urine routine, urine culture & sensitivity, renal function tests (creatinine), ultrasound KUB if complicated.
3.3 Skin & Soft Tissue Infections
Impetigo, cellulitis (non-MRSA), wound infections — common organisms Streptococci and MSSA (methicillin-sensitive S. aureus).
Tests: Wound swab culture, CBC, blood glucose if diabetic (glycemic control critical).
3.4 Bone & Joint infections (selected)
As part of combination therapy for osteomyelitis when organisms are susceptible; requires prolonged therapy and specialist input. Tests: X-ray, MRI, bone biopsy culture.
3.5 Typhoid / Enteric fever (historical/limited use)
Cefuroxime has activity against Salmonella Typhi in vitro; in many regions rising resistance exists — blood culture & sensitivity essential before relying on cefuroxime. Tests: blood culture (gold standard), Widal (low specificity).
3.6 Meningitis & severe systemic infections
Parenteral cefuroxime can be used for certain CNS infections but often third-generation cephalosporins (ceftriaxone, cefotaxime) or other agents preferred due to CNS penetration considerations. Always follow guidelines and local antibiogram.
4. MBBS/MD क्या करते हैं vs झोलाछाप (quack/Bangali) व्यवहार
MBBS/MD doctors: Indication-based prescribing — culture where appropriate, dose adjusting for renal function, complete course, antibiotic stewardship, monitor for side effects, provide supportive therapy and follow-up.
झोलाछाप / अनप्रोफेशनल: कई बार cefuroxime (या broad-spectrum antibiotics) छोटे वायरस संबंधित सर्दी/खांसी में दे देते हैं, half course या irrational combination देते हैं — इससे resistance, adverse effects और diagnostic delay होता है.
Clinical note: Antibiotic misuse increases local resistance rates — follow guideline-based prescribing and encourage patients to avoid self-medication.
5. Dosing — Adult, Pediatric, Special situations (Detailed mg dosing)
Oral (Cefuroxime axetil)
| Indication | Adult Dose (oral) | Duration (typical) |
|---|---|---|
| Uncomplicated UTI / Otitis media / Sinusitis | 250 mg twice daily | 5–7 days (as per response) |
| Community Acquired Pneumonia (mild–moderate) | 500 mg twice daily | 7–14 days (depending severity) |
| Skin & soft tissue infection | 500 mg twice daily | 7–14 days |
| Typhoid (if susceptible) | 500 mg twice daily | 10–14 days (only if C/S supports) |
Parenteral (Cefuroxime sodium) — IV/IM
| Indication | Adult Dose (IV/IM) | Notes |
|---|---|---|
| Severe infections / Pneumonia / Sepsis | 750 mg — 1.5 g IV every 8 hours (max vary by severity) | Switch to oral when stable |
| Hospitalized complicated UTI / Pyelonephritis | 750 mg IV/IM every 8 hours | Adjust per renal function |
Pediatric dosing (oral Cefuroxime axetil)
- Typical: 10–15 mg/kg per dose orally twice daily (max ~500 mg per dose).
- For severe infections: 30–100 mg/kg/day divided doses (specialist guidance).
Renal impairment adjustments
Cefuroxime is primarily renally excreted. For CrCl <30 mL/min, extend dosing interval or reduce dose — follow local renal dosing charts. Example: for severe renal impairment, give 250–500 mg once daily or extend interval to 24–48 h depending on CrCl — check product monograph.
Pregnancy & Lactation
Cefuroxime is category B (data suggest no teratogenicity). Use when clinically indicated. Small amounts excreted in breastmilk — generally compatible with breastfeeding; monitor infant for diarrhea or candidiasis.
6. Tests, Monitoring & Lab Correlates
Before and during therapy (as indicated):
- Baseline: CBC, renal function (serum creatinine, eGFR), liver function tests if hepatic disease history.
- Microbiology: If systemic or complicated infection → obtain culture & sensitivity (sputum, blood, urine, wound) BEFORE starting antibiotics when possible.
- During therapy: Monitor clinical response (fever curve, symptomatic improvement), repeat culture if worsening, monitor renal function in elderly/renal disease, watch for signs of Clostridioides difficile (severe diarrhea).
Therapeutic failures should prompt reassessment: adherence, absorption (oral), resistant organisms (ESBL), deep focus (abscess) requiring drainage, or wrong diagnosis (viral vs bacterial).
7. Combination therapy & Common co-prescriptions
Cefuroxime is combined with other agents to broaden coverage or target mixed infections — examples:
- Metronidazole: for anaerobic coverage in intra-abdominal infections, dental infections.
- Macrolide (Azithromycin): atypical coverage in CAP (e.g., Mycoplasma, Chlamydophila).
- Fluids & antipyretics (Paracetamol): symptomatic support.
- Analgesics & topical care for skin infections.
Avoid unnecessary multi-antibiotic combinations. Use microbiology to guide therapy where feasible.
8. Side effects, Allergies, Serious adverse events
- Gastrointestinal: nausea, vomiting, diarrhea (including risk of C. difficile colitis)
- Hypersensitivity: rash, urticaria, anaphylaxis (rare). Cross-reactivity with penicillins possible — enquire penicillin allergy history.
- Hematologic: neutropenia, eosinophilia (rare)
- Hepatic: transient LFT elevation (rare)
- Renal: interstitial nephritis (rare)
Immediate action: If signs of anaphylaxis (hypotension, bronchospasm, angioedema), stop drug and initiate emergency treatment (epinephrine, airway, IV fluids, antihistamines, corticosteroids).
9. Contraindications & Cautions
- Known severe allergy to cephalosporins.
- History of anaphylaxis to penicillins — caution; consider non-β-lactam alternative.
- Severe renal impairment — adjust dose and monitor.
- C. difficile colitis history — use with caution.
10. Food, Alcohol & Dietary advice while on Cefuroxime
Food: Cefuroxime axetil absorption ↑ when taken with food — advise patients to take oral tablet with a meal or within 30 minutes of food for optimal absorption (especially 500 mg dose).
Alcohol: No direct disulfiram-like effect reported with cefuroxime, but avoid alcohol to reduce GI side effects and support recovery.
Recommended foods: Light, nutritious meals — fruits rich in vitamin C (e.g., guava, citrus) to support immunity; complex carbs and protein for recovery; adequate hydration.
Avoid: Heavy fatty meals that may reduce gastric emptying and contribute to nausea; raw/unhygienic foods if infection risk present.
11. Special situations — Pregnancy, Lactation, Elderly, Renal disease
Pregnancy
Cefuroxime is generally considered safe; use when benefit outweighs risk. Avoid unnecessary antibiotics in pregnancy. For complicated infections, follow obstetric infectious disease guidance.
Lactation
Small quantities excreted in breast milk — usually safe; monitor infant for diarrhea or thrush.
Elderly
Renal function declines with age → dose adjustment/monitoring required. Polypharmacy common — review interactions.
Renal disease
Adjust dose per eGFR/CrCl and monitor levels/response.
12. Antibiotic Stewardship — Practical prescribing rules
- Confirm bacterial infection (culture when possible) — avoid antibiotics for viral URTI.
- Prescribe narrowest effective spectrum agent guided by local antibiogram.
- Document indication, planned duration, and review at 48–72 hours
- Complete full prescribed course unless guided to stop by clinician
- Educate patient about side effects, drug interactions and follow-up.
13. Example clinical scenarios & sample prescriptions (for reference only)
Case A: Community acquired pneumonia, mild — Adult outpatient
Rx: Cefuroxime axetil 500 mg PO twice daily for 7 days + Paracetamol PRN for fever. Sputum culture if productive cough. Follow up day 3–5.
Case B: Complicated UTI — Hospitalized adult
Rx: Cefuroxime sodium 750 mg IV every 8 hours (adjust renal) + switch to oral 500 mg BID once afebrile and clinically improved. Urine culture and sensitivity before antibiotics.
Case C: Cellulitis — diabetic patient
Rx: Cefuroxime 500 mg PO BD (if mild and culture suggests susceptible organism) + glycemic control; if severe → IV therapy and surgical consult for debridement if abscess.
14. Major Drug Interactions
- Probenecid: reduces renal tubular secretion → increased cefuroxime levels.
- Loop diuretics/aminoglycosides: combined nephrotoxicity risk — monitor renal function.
- Oral contraceptives: antibiotics may reduce effectiveness of OCPs in some cases — advise backup method during severe diarrhea.
- Anticoagulants: Cephalosporins may rarely potentiate warfarin effect → monitor INR if concomitant use.
15. Patient counselling points
- Take oral cefuroxime with food for better absorption and less GI upset.
- Complete full course even if symptoms improve early (unless directed).
- Report rash, severe diarrhea, difficulty breathing immediately.
- Avoid self-medication and antibiotics leftover use; return unused meds for safe disposal.
