Objective: To review the evidence and discuss use of pivmecillinam in uncomplicated acute cystitis.
Data Sources: A literature search was conducted utilizing PubMed (from 2000 through August 2024) and ClinicalTrials.gov. Medical Subject Headings (MeSH) terms, such as mecillinam or pivmecillinam and urinary tract infections, were utilized. Additional references were identified by reviewing literature citations.
Study Selection And Data Extraction: Articles were limited to English language publications evaluating the efficacy or safety of pivmecillinam for urinary tract infections (UTIs) in adult populations.
Data Synthesis: Data from 6 randomized controlled trials support pivmecillinam for acute uncomplicated cystitis at doses of 200 to 400 mg 3 times daily for 3 to 7 days, with more consistent clinical and bacteriologic cure observed with 400 mg doses and longer therapy durations. Clinical evaluation of 400 mg 2 to 3 times daily is available with use more common in non-US Food and Drug Administration (FDA)-approved populations, such as men, pregnancy, and multidrug resistant infections. There are limited data supporting pivmecillinam for pyelonephritis; routine use is cautioned until further clinical data are available.
Relevance To Patient Care And Clinical Practice In Comparison With Existing Drugs: As resistance to first-line antimicrobials rises, the need for safe and effective treatment options remains high. Pivmecillinam represents a new therapeutic option available in the United States for outpatient management of uncomplicated acute cystitis.
Conclusion: Pivmecillinam could be a key agent for uncomplicated acute cystitis. Utilization will likely be cost driven, but the promise of low resistance encourages the place in therapy when other agents are not susceptible to infecting uropathogens.
