Moxikind CV Dosing in Pediatric Patients
For pediatric patients, Moxikind CV (amoxicillin-clavulanate) should be dosed at 90 mg/kg/day of the amoxicillin component divided into 2 doses (maximum 4000 mg/day) for most infections, particularly respiratory tract infections, acute otitis media, and sinusitis. 1
Standard Dosing Algorithm
Age-Based Dosing for Routine Infections
For children with mild to moderate infections without risk factors for resistant organisms:
- Less than 1 year (1-12 months): 2.5 ml of 125/31 suspension three times daily 1
- 1-6 years: 5 ml of 125/31 suspension three times daily 1
- 7-12 years: 5 ml of 250/62 suspension three times daily 1
- 12-18 years: 1 tablet (250/125) three times daily 1
High-Dose Regimen (Preferred for Most Infections)
The high-dose regimen of 90 mg/kg/day of amoxicillin with 6.4 mg/kg/day of clavulanate divided into 2 doses is strongly recommended for children with any of the following risk factors 1:
- Age less than 2 years 1
- Daycare attendance 1
- Recent antibiotic use within the past 30 days 1
- Incomplete Haemophilus influenzae type b vaccination 1
- Geographic areas with high prevalence (>10%) of penicillin-resistant Streptococcus pneumoniae 1
- Moderate to severe illness 1
This high-dose formulation provides a 14:1 ratio of amoxicillin to clavulanate, which causes less diarrhea than other preparations while maintaining superior efficacy against resistant organisms 1, 2.
Indication-Specific Dosing
Respiratory Tract Infections
- Community-acquired pneumonia: 90 mg/kg/day of amoxicillin component in 2 divided doses for 10 days 1
- Acute bacterial rhinosinusitis: 90 mg/kg/day divided twice daily for 10-14 days 1
- Acute otitis media: 90 mg/kg/day divided twice daily for 10 days, particularly for severe, bilateral, or recurrent cases 1
Alternative Lower-Dose Regimen
For β-lactamase producing organisms in children without high-resistance risk factors, an alternative regimen of 45 mg/kg/day in 3 divided doses may be used 1. However, the 90 mg/kg/day twice-daily regimen is preferred as it provides better coverage and improved compliance 1.
Maximum Dosing Limits
- Maximum single dose: 2 grams per dose regardless of weight 1
- Maximum daily dose: 4000 mg (4 g) of amoxicillin component per day 1
Intravenous Dosing
For severe infections requiring parenteral therapy: 30 mg/kg three times daily IV 1
Treatment Duration
- Most respiratory infections: 7-10 days 1
- Pneumonia and acute otitis media: 10 days 1
- Acute bacterial rhinosinusitis: 10-14 days 1
- Continue therapy for at least 48-72 hours after the patient becomes asymptomatic 3
Critical Clinical Considerations
Monitoring Response
Clinical improvement should be evident within 48-72 hours of starting therapy 1. If no improvement or worsening occurs after 72 hours, reevaluation is necessary with consideration of:
- Atypical pathogens 1
- Complications requiring imaging 1
- Alternative diagnoses 1
- Treatment failure requiring antibiotic change 1
Common Pitfalls to Avoid
- Verify suspension concentration (125/31 vs 250/62) before calculating volume to prevent dosing errors 1
- Do not use subtherapeutic doses, as they fail to achieve adequate tissue concentrations and promote antimicrobial resistance 1
- Avoid using standard doses when high-dose therapy is indicated, as this leads to treatment failure with resistant organisms 1
- Ensure most URTIs are actually bacterial before prescribing, as the majority are viral and do not benefit from antibiotics 1
Renal Impairment Adjustments
For children with severe renal impairment (GFR <30 mL/min), dosing adjustments are required 3:
- GFR 10-30 mL/min: 500 mg or 250 mg every 12 hours 3
- GFR <10 mL/min: 500 mg or 250 mg every 24 hours 3
Administration Instructions
- Administer at the start of meals to minimize gastrointestinal intolerance 3
- Shake oral suspension well before each use 3
- Refrigeration is preferable but not required 3
- Discard unused reconstituted suspension after 14 days 3
Tolerability Profile
The high-dose formulation (90/6.4 mg/kg/day) demonstrates similar tolerability to conventional formulations, with diarrhea being less frequent with twice-daily dosing compared to three-times-daily regimens 1, 2. Common adverse effects include mild gastrointestinal disturbances, with a low overall incidence of serious adverse events 2.
