Implication

Systematic review demonstrates superior bacterial eradication with multi-day antibiotic regimens in women with cystitis, indicating class-specific optimal treatment durations.

Key Points

Evaluate the efficacy and tolerability of varying antibiotic treatment durations—specifically single-dose, 3-day, and ≥5-day courses—for uncomplicated lower urinary tract infections in women.
Reviewed 28 clinical trials conducted in women diagnosed with uncomplicated cystitis.
Compared bacteriuria eradication and adverse event rates across single-dose, 3-day, and ≥5-day regimens of beta-lactams, trimethoprim/sulfonamide combinations, norfloxacin, penicillins, and oral cephalosporins.
Single-dose therapy was less effective at eradicating bacteriuria than 3-day or ≥5-day regimens across all antibiotic classes, with the disparity being most pronounced for beta-lactams.
Trimethoprim/sulfonamide regimens achieved optimal efficacy with a 3-day course, providing no additional antibacterial benefit at ≥5 days while markedly increasing adverse reactions beyond 3 days.
Beta-lactam antibiotics demonstrated higher efficacy when administered for ≥5 days compared to 3-day courses, with oral cephalosporin adverse reactions increasing as treatment duration extended.
