Cefpodoxime CV

# cefpodoxime CV ## Overview - **Classification**: Third-generation cephalosporin antibiotic. - **Mechanism**: Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to bacterial lysis. ## Primary Indications 1. **Acute Otitis Media (AOM)** - Bacterial ear infection. 2. **Pharyngitis/Tonsillitis** - Streptococcal pharyngitis (e.g., strep throat). 3. **Community-Acquired Pneumonia (CAP)** - Bacterial lung infection. 4. **Acute Bacterial Exacerbation of Chronic Bronchitis (ABECB)** - Worsening of chronic bronchitis. 5. **Uncomplicated Urinary Tract Infections (UTIs)** - Bladder infections. 6. **Uncomplicated Skin & Skin Structure Infections (SSSIs)** - Mild to moderate skin infections. ## Adult Dosing ### Standard Dosing **Acute Otitis Media (AOM)** - **Dose**: **200 mg** - **Frequency**: Every 12 hours (q12h) - **Route**: Oral (PO) - **Duration**: 5-10 days **Pharyngitis/Tonsillitis** - **Dose**: **100 mg** - **Frequency**: Every 12 hours (q12h) - **Route**: Oral (PO) - **Duration**: 5-10 days **Community-Acquired Pneumonia (CAP)** - **Dose**: **200 mg** - **Frequency**: Every 12 hours (q12h) - **Route**: Oral (PO) - **Duration**: 14 days **Acute Bacterial Exacerbation of Chronic Bronchitis (ABECB)** - **Dose**: **200 mg** - **Frequency**: Every 12 hours (q12h) - **Route**: Oral (PO) - **Duration**: 10 days **Uncomplicated Urinary Tract Infections (UTIs)** - **Dose**: **100 mg** - **Frequency**: Every 12 hours (q12h) - **Route**: Oral (PO) - **Duration**: 7 days **Uncomplicated Skin & Skin Structure Infections (SSSIs)** - **Dose**: **400 mg** - **Frequency**: Every 12 hours (q12h) - **Route**: Oral (PO) - **Duration**: 7-14 days ### Dose Adjustments - **Renal Impairment**: - Creatinine Clearance (CrCl) **30 mL/min or greater**: No adjustment needed. - CrCl **less than 30 mL/min**: Administer standard dose every **24 hours**. - Hemodialysis: Administer standard dose 3 times per week, after dialysis. - **Hepatic Impairment**: No dose adjustment is generally required. - **Elderly Patients**: Dose based on renal function; no specific age-based adjustment. ## Pediatric Dosing ### Neonates (0-28 days) - **Special Notes**: Not routinely recommended. Limited safety and efficacy data in neonates. Use only if potential benefit outweighs risk, with close monitoring. ### Infants (1-12 months) **Acute Otitis Media (AOM)** - **Dose**: **5 mg/kg/dose** - **Frequency**: Every 12 hours (q12h) - **Maximum**: **200 mg/dose** - **Special Notes**: Oral suspension preferred. **Pharyngitis/Tonsillitis** - **Dose**: **5 mg/kg/dose** - **Frequency**: Every 12 hours (q12h) - **Maximum**: **100 mg/dose** - **Special Notes**: Oral suspension preferred. ### Children (1-12 years) **Acute Otitis Media (AOM)** - **Dose**: **5 mg/kg/dose** - **Frequency**: Every 12 hours (q12h) - **Maximum**: **200 mg/dose** **Pharyngitis/Tonsillitis** - **Dose**: **5 mg/kg/dose** - **Frequency**: Every 12 hours (q12h) - **Maximum**: **100 mg/dose** **Acute Maxillary Sinusitis (AMS)** - **Dose**: **5 mg/kg/dose** - **Frequency**: Every 12 hours (q12h) - **Maximum**: **200 mg/dose** - **Duration**: 10 days **Uncomplicated Urinary Tract Infections (UTIs)** - **Dose**: **5 mg/kg/dose** - **Frequency**: Every 12 hours (q12h) - **Maximum**: **100 mg/dose** - **Duration**: 7 days ### Adolescents (13-18 years) - **Dose**: Follow **Adult Dosing** recommendations for specific indications. - **Maximum**: Do not exceed adult maximum daily doses. ## Safety Information ### Contraindications - **Absolute**: Hypersensitivity to cefpodoxime, other cephalosporins, or severe penicillin allergy. - **Absolute**: Anaphylactic reaction to any penicillin. ### Common Adverse Effects - **Very Common (>10%)**: Diarrhea (especially with higher doses). - **Common (1-10%)**: Nausea, vomiting, abdominal pain, headache, rash, fungal infections (e.g., vaginal candidiasis). - **Serious but Rare**: *Clostridioides difficile*-associated diarrhea (CDAD), severe hypersensitivity reactions (anaphylaxis, SJS, TEN), seizures (especially in renal impairment). ### Key Drug Interactions - **Antacids/H2 blockers/PPIs**: Decreased cefpodoxime absorption. Administer cefpodoxime **at least 2 hours before or after** antacids/H2 blockers. - **Probenecid**: Increases cefpodoxime plasma concentrations by inhibiting renal excretion. - **Warfarin**: May increase INR and risk of bleeding. Monitor INR closely. ## Monitoring & Follow-up - **Before Treatment**: Assess patient's allergy history, especially to cephalosporins and penicillins. - **During Treatment**: - Monitor for signs of allergic reactions (rash, hives, difficulty breathing). - Watch for severe diarrhea, which could indicate *C. difficile* infection. - Monitor renal function in patients with pre-existing impairment. - **Clinical Signs**: Monitor for resolution of infection symptoms. Follow-up for any persistent or worsening symptoms. ## Clinical Pearls - 💡 **Take with Food**: Administer cefpodoxime with food to enhance absorption and reduce GI upset. - 💡 **Suspension Stability**: Cefpodoxime oral suspension is stable for **14 days** when refrigerated (2-8°C / 36-46°F). Discard unused portion after 14 days. - 💡 **Cross-Reactivity**: Use with caution in patients with penicillin allergy due to potential cross-reactivity (estimated <1%). - 💡 **Complete Course**: Advise patients to complete the entire course of therapy, even if symptoms improve, to prevent resistance and relapse. > **⚠️ Important**: This information is for educational purposes only.
