Overview

â„šī¸

What is this medicine?

Augmentin ES-600 is an antibiotic that contains two medicines: amoxicillin and clavulanate. Amoxicillin kills bacteria by stopping them from building their cell walls. Clavulanate helps amoxicillin work better by blocking certain enzymes that bacteria make to destroy amoxicillin. This medicine is often used to treat ear infections, sinus infections, and other bacterial infections, especially in children.

Dosing & Administration

đŸ‘¨â€âš•ī¸

Adult Dosing

Standard Dose: Not typically used in adults due to the high amoxicillin to clavulanate ratio (14:1) which is designed for pediatric use. Adult formulations usually have a 4:1 or 7:1 ratio.
đŸ‘ļ

Pediatric Dosing

Neonatal: Not established. Use with caution and only if potential benefit outweighs risk.
Infant: For infants â‰Ĩ 3 months and children: 90 mg/kg/day of amoxicillin component, divided every 12 hours for 10 days. (e.g., for AOM, sinusitis). Max 600 mg amoxicillin/dose.
Child: For infants â‰Ĩ 3 months and children: 90 mg/kg/day of amoxicillin component, divided every 12 hours for 10 days. (e.g., for AOM, sinusitis). Max 600 mg amoxicillin/dose.
Adolescent: For adolescents weighing < 40 kg, use pediatric dosing. For those â‰Ĩ 40 kg, adult dosing (though ES-600 is not standard adult formulation) or specific pediatric high-dose regimens may apply based on indication.
âš•ī¸

Dose Adjustments

Renal Impairment:

Mild: CrCl > 30 mL/min: No dosage adjustment needed.
Moderate: CrCl 10-30 mL/min: Not recommended for ES-600 due to fixed ratio. If used, consider alternative formulations or significant dose reduction and extended interval. Consult specific guidelines.
Severe: CrCl < 10 mL/min: Not recommended for ES-600 due to fixed ratio. If used, consider alternative formulations or significant dose reduction and extended interval. Consult specific guidelines.
Dialysis: Hemodialysis: Not recommended for ES-600. Both amoxicillin and clavulanate are removed by hemodialysis. If used, administer dose after dialysis and monitor closely. Consult specific guidelines.

Hepatic Impairment:

Mild: Use with caution; monitor liver function.
Moderate: Use with caution; monitor liver function. Dosage adjustment not specifically defined, but close monitoring is crucial.
Severe: Use with caution; monitor liver function. Dosage adjustment not specifically defined, but close monitoring is crucial.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Amoxicillin is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to bacterial lysis and death. Clavulanate potassium is a beta-lactamase inhibitor that irreversibly binds to and inactivates a wide range of bacterial beta-lactamase enzymes, thereby protecting amoxicillin from hydrolysis and extending its antibacterial spectrum against beta-lactamase-producing strains.

🆘

Overdose Information

Overdose Symptoms:

  • Gastrointestinal symptoms (e.g., stomach pain, vomiting, diarrhea)
  • Fluid and electrolyte imbalance
  • Rash
  • Hyperactivity
  • Drowsiness
  • Renal dysfunction (crystalluria, in severe cases)
  • Convulsions (rare, in patients with impaired renal function or high doses)

What to Do:

Seek immediate medical attention or call a poison control center (e.g., 1-800-222-1222). Treatment is generally supportive, including symptomatic management and maintaining fluid and electrolyte balance. Hemodialysis can remove amoxicillin and clavulanate from circulation.

Drug Interactions

🔴

Major Interactions

  • Methotrexate: Amoxicillin can decrease renal tubular secretion of methotrexate, increasing its plasma concentrations and potential toxicity. Avoid concomitant use or monitor methotrexate levels closely.
  • Warfarin and other oral anticoagulants: May prolong prothrombin time (INR). Monitor INR closely and adjust anticoagulant dose as needed.
🟡

Moderate Interactions

  • Allopurinol: Concomitant use with amoxicillin may increase the incidence of skin rash, particularly in patients with hyperuricemia.
  • Oral Contraceptives: May reduce the efficacy of oral contraceptives. Advise patients to use an alternative or additional method of contraception.
  • Probenecid: Decreases renal tubular secretion of amoxicillin, resulting in increased and prolonged blood levels of amoxicillin. Not recommended for concomitant use.
  • Mycophenolate mofetil: Amoxicillin/clavulanate may reduce mycophenolate mofetil concentrations. Monitor for reduced efficacy of mycophenolate.
đŸŸĸ

Minor Interactions

  • Typhoid vaccine (live, oral): Antibiotics may inactivate the live bacterial vaccine. Administer at least 24 hours apart.

Monitoring

đŸ”Ŧ

Baseline Monitoring

Renal function (BUN, creatinine)

Rationale: To establish baseline and guide dosing in patients with pre-existing renal impairment, as the drug is primarily renally eliminated.

Timing: Prior to initiation, especially in patients with known or suspected renal dysfunction.

Liver function tests (ALT, AST, bilirubin)

Rationale: To establish baseline, particularly in patients with pre-existing hepatic impairment, as hepatic dysfunction has been associated with amoxicillin/clavulanate.

Timing: Prior to initiation, especially in patients with known or suspected hepatic dysfunction.

📊

Routine Monitoring

Clinical response to therapy (e.g., resolution of fever, improvement of symptoms)

Frequency: Daily during acute treatment

Target: Improvement of infection symptoms

Action Threshold: Lack of improvement or worsening symptoms may indicate treatment failure, resistance, or alternative diagnosis.

Signs and symptoms of adverse reactions (e.g., diarrhea, rash, allergic reactions)

Frequency: Daily throughout therapy and for several weeks post-therapy for delayed reactions.

Target: Absence of adverse effects

Action Threshold: Development of severe diarrhea (C. difficile), widespread rash, difficulty breathing, or signs of liver injury requires immediate evaluation and potential discontinuation.

Renal and hepatic function tests

Frequency: Periodically during prolonged therapy (e.g., >14 days) or in patients with pre-existing impairment.

Target: Within normal limits or stable from baseline.

Action Threshold: Significant elevation may require dose adjustment or discontinuation.

đŸ‘ī¸

Symptom Monitoring

  • Diarrhea (especially severe or bloody diarrhea, which could indicate C. difficile-associated diarrhea)
  • Skin rash, itching, hives (signs of allergic reaction)
  • Difficulty breathing or swallowing, swelling of face/lips/tongue (signs of severe allergic reaction/anaphylaxis)
  • Yellowing of skin or eyes (jaundice), dark urine, pale stools, abdominal pain (signs of liver dysfunction)
  • Unusual bruising or bleeding (potential effect on coagulation)
  • Signs of superinfection (e.g., oral thrush, vaginal yeast infection)

Special Patient Groups

🤰

Pregnancy

Category B. Studies in animals have not shown harm to the fetus, and there are no adequate and well-controlled studies in pregnant women. Generally considered safe for use during pregnancy when clearly needed.

Trimester-Specific Risks:

First Trimester: No increased risk of major birth defects observed in human studies.
Second Trimester: No specific risks identified.
Third Trimester: No specific risks identified. Caution advised near term due to potential for neonatal adverse effects (e.g., necrotizing enterocolitis, though rare and not definitively linked).
🤱

Lactation

L2 (Safer). Both amoxicillin and clavulanate are excreted in breast milk in small amounts. Generally considered compatible with breastfeeding, but monitor the infant for potential adverse effects.

Infant Risk: Low risk. Potential for diarrhea, candidiasis (thrush, diaper rash), or allergic sensitization in the breastfed infant. Observe infant for rash or gastrointestinal upset.
đŸ‘ļ

Pediatric Use

Augmentin ES-600 is specifically formulated and primarily indicated for pediatric patients (â‰Ĩ 3 months of age) for specific infections like acute otitis media and sinusitis, where high-dose amoxicillin is required and the clavulanate component is minimized to reduce gastrointestinal side effects. Dosing is weight-based.

👴

Geriatric Use

No overall differences in safety or effectiveness have been observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Dosage adjustment is necessary in elderly patients with impaired renal function.

Clinical Information

💎

Clinical Pearls

  • Augmentin ES-600 (14:1 ratio) is specifically designed for pediatric patients with acute otitis media and sinusitis where high-dose amoxicillin is needed, and the clavulanate component is minimized to reduce diarrhea.
  • Always ensure the correct formulation (e.g., ES-600, 4:1, 7:1) is dispensed and administered, as the amoxicillin:clavulanate ratio varies and affects dosing and side effect profiles.
  • Instruct patients to take the medication at the start of a meal to enhance absorption and reduce gastrointestinal intolerance.
  • Emphasize the importance of completing the full course of therapy, even if symptoms improve, to prevent the development of antibiotic resistance.
  • Reconstituted suspension must be refrigerated and discarded after 10 days.
  • Monitor for signs of C. difficile-associated diarrhea, which can occur during or even several weeks after antibiotic therapy.
