Adjustments are often necessary, particularly for the pediatric and geriatric populations who may metabolize the drug differently.
Standard Regimens (Health Canada Approved)
For conditions such as urinary tract infections and certain skin infections, the typical doses include:
- 1 g every 12 hours for urinary tract infections
- 1 g every 12 hours for skin infections
- 500 mg every 12 hours for throat infections
Adjustments for Comorbidities (e.g., Diabetes, Common in Canadian Population)
Patients with diabetes or other comorbidities may require careful dosage adjustments. Renal function should be monitored closely, especially in older adults or those with pre-existing conditions. If renal impairment is present, cefadroxil dosing might shift, extending the intervals between doses.
Q&A — “What If I Miss a Dose Under My Provincial Drug Plan?”
If a dose is missed, it should be taken as soon as remembered. However, if the time for the next dose is near, the missed dose should be skipped. Doubling up on doses can lead to increased side effects and complications.
Mechanism & Pharmacology
Cefadroxil functions as a cephalosporin antibiotic, primarily disrupting bacterial cell wall synthesis, which is critical for their growth and survival. When bacteria encounter cefadroxil, the drug inhibits specific enzymes known as penicillin-binding proteins (PBPs). These enzymes are essential in forming the bonds within the cell wall. As a result, the bacteria are unable to maintain their structural integrity, leading to cell lysis and death.
Simplified explanation
Picture a city's protective wall. If there's a breach, the city is at risk of collapsing. Cefadroxil acts like a bulldozer, preventing the builders (bacteria) from fixing any cracks. By blocking vital tools they need to construct and maintain their walls, the antibiotic ensures the bacteria can't survive and multiply.
Clinical terms
Cefadroxil is classified under the ATC code J01DB05 as a first-generation cephalosporin. It targets infections caused by susceptible gram-positive and some gram-negative bacteria. According to the Health Canada monograph, it binds to PBPs, disrupting the transpeptidation process essential for peptidoglycan cross-linking in bacterial cell walls.
Indications & Off-Label Uses in Canada
Cefadroxil is an effective treatment for a variety of infections. Among its primary uses are uncomplicated urinary tract infections (UTIs), skin, and soft tissue infections, and pharyngitis or tonsillitis.
