🌿 What is Augmentin 375 mg?
Augmentin 375 mg combines amoxicillin, a broad-spectrum penicillin antibiotic, with clavulanic acid, a β-lactamase inhibitor. This formulation enhances amoxicillin’s efficacy against β-lactamase–producing bacteria, expanding its spectrum to include resistant strains of Staphylococcus, Haemophilus influenzae, Moraxella catarrhalis, and various anaerobes. Augmentin is indicated for acute otitis media, sinusitis, community-acquired pneumonia, skin and soft tissue infections, and urinary tract infections.
🧬 Pharmacology & Mechanism of Action
| Component | Mechanism |
|---|---|
| Amoxicillin 250 mg | • Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) → bactericidal activity. |
| Clavulanic Acid 125 mg | • Irreversibly inhibits β-lactamase enzymes produced by resistant bacteria → protects amoxicillin from degradation. |
| Pharmacokinetics | • Absorption: ~75–80% oral bioavailability; unaffected by food. |
| • Distribution: Widely distributed; achieves therapeutic levels in middle ear fluid, sinuses, lung tissue. | |
| • Metabolism & Excretion: Excreted primarily unchanged via urine; clavulanic acid partially metabolized hepatically. | |
| • Half-Life: Amoxicillin: ~1 hour; Clavulanic acid: ~1 hour. |
