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. Clavulanate is a beta-lactamase inhibitor that irreversibly binds to and inactivates a wide range of beta-lactamase enzymes produced by many Gram-positive and Gram-negative bacteria, thereby protecting amoxicillin from degradation and extending its antibacterial spectrum.

Special Patient Groups

🤰

Pregnancy

Amoxicillin/clavulanate is classified as 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. It is generally considered safe for use during pregnancy when clearly needed.

Trimester-Specific Risks:

First Trimester: Generally considered low risk; no increased risk of major malformations observed.
Second Trimester: Generally considered safe.
Third Trimester: Generally considered safe; however, caution is advised near term due to potential for increased risk of necrotizing enterocolitis in neonates (though data is limited and conflicting).
🤱

Lactation

Amoxicillin and clavulanate are excreted in breast milk in small amounts. Generally considered compatible with breastfeeding (Lactation Risk Category L2).

Infant Risk: Low risk. Potential for infant sensitization, diarrhea, candidiasis (thrush, diaper rash). Monitor breastfed infants for gastrointestinal symptoms (diarrhea, candidiasis) or allergic reactions (rash).
đŸ‘ļ

Pediatric Use

This 200/28.5mg chewable tablet formulation is primarily indicated for pediatric patients. Dosing must be carefully calculated based on the child's weight and the severity/type of infection, using the amoxicillin component. Ensure appropriate strength and formulation (e.g., chewable vs. suspension) for the child's age and ability to take medication.

👴

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. Dose adjustment is necessary in elderly patients with renal impairment, as amoxicillin and clavulanate are primarily eliminated by the kidneys. Monitor renal function.

Clinical Information

💎

Clinical Pearls

  • Always advise patients to take amoxicillin/clavulanate at the start of a meal to enhance absorption and minimize GI side effects, particularly diarrhea.
  • Emphasize the importance of completing the full course of therapy, even if symptoms improve, to prevent resistance and recurrence.
  • Counsel patients on the potential for C. difficile-associated diarrhea, and to seek medical attention if severe, watery, or bloody diarrhea occurs.
  • Be aware of the potential for drug-induced liver injury, which can occur during or several weeks after therapy. Monitor liver function in patients on prolonged therapy or with pre-existing liver conditions.
  • This 200/28.5mg chewable tablet is a lower strength, typically used for pediatric patients with specific dosing regimens (e.g., 45 mg/kg/day divided q12h). Ensure correct strength and formulation are prescribed for the patient's age and weight.
