In a healthy non‑pregnant adult woman with typical cystitis symptoms, is citralka effective for treating acute uncomplicated urinary tract infection?

Citralka (Potassium Citrate) Is Not Recommended for Treating Acute Uncomplicated UTI

Citralka (potassium citrate) is a urinary alkalinizer that has no role in the treatment of acute uncomplicated urinary tract infection and should not be used as antimicrobial therapy. The condition requires antibiotics that eradicate uropathogens, not agents that merely alter urine pH.

Why Citralka Does Not Treat UTI

• Citralka lacks antimicrobial activity against Escherichia coli, which causes 75–95% of uncomplicated cystitis cases, and provides no bactericidal or bacteriostatic effect against any uropathogen. 1

• Urinary alkalinization does not eliminate bacterial infection and will not achieve the clinical cure rates (≈93%) or microbiological eradication rates (≈88–94%) demonstrated by evidence-based first-line antibiotics. 1

• No international guideline—including those from the Infectious Diseases Society of America, European Association of Urology, or American Urological Association—lists citralka or any urinary alkalinizer as a treatment option for uncomplicated cystitis. 2, 1

Evidence-Based First-Line Antibiotic Options

Nitrofurantoin 100 mg orally twice daily for 5 days is the preferred regimen, achieving approximately 93% clinical cure and 88% microbiological eradication with worldwide resistance rates below 1% and minimal disruption of intestinal flora. 1

Alternative First-Line Agents

• Fosfomycin trometamol 3 g as a single oral dose provides ≈91% clinical cure, maintains therapeutic urinary concentrations for 24–48 hours, and has initial-infection resistance rates around 2.6%. 1

• Trimethoprim-sulfamethoxazole (TMP-SMX) 160/800 mg orally twice daily for 3 days yields ≈93% clinical cure and ≈94% microbiological eradication only when local E. coli resistance is <20% and the patient has not received TMP-SMX in the preceding 3 months. 2, 1

When to Obtain Urine Culture

• Routine urine culture is not required for otherwise healthy women presenting with typical lower urinary symptoms (dysuria, frequency, urgency) in the absence of vaginal discharge. 3

• Obtain culture and susceptibility testing when any of the following occur:

  • Persistent symptoms after completing the prescribed regimen 3
  • Recurrence of symptoms within 2–4 weeks 3
  • Fever >38°C, flank pain, or costovertebral angle tenderness suggesting pyelonephritis 3
  • Atypical presentation or presence of vaginal discharge 3
  • History of recurrent infections (≥3 episodes in 12 months or ≥2 episodes in 6 months) 3

Reserve (Second-Line) Therapies

• Fluoroquinolones (ciprofloxacin 250–500 mg twice daily or levofloxacin 250–750 mg once daily for 3 days) should be reserved exclusively for culture-proven resistant pathogens or documented failure of first-line agents because serious adverse effects (tendon rupture, peripheral neuropathy, CNS toxicity) outweigh benefits in uncomplicated UTI. 1

• Beta-lactam agents (amoxicillin-clavulanate, cefdinir, cefpodoxime for 3–7 days) achieve only ≈89% clinical cure and ≈82% microbiological eradication, which is significantly inferior to nitrofurantoin, fosfomycin, or TMP-SMX; they should be used only when first-line options are contraindicated. 1

• Amoxicillin or ampicillin alone should never be employed because worldwide E. coli resistance exceeds 55–67%. 1

Treatment Algorithm

1. Confirm uncomplicated cystitis (dysuria, frequency, urgency without fever, flank pain, pregnancy, catheter, immunosuppression, or recent instrumentation). 3

2. Assess local E. coli TMP-SMX resistance:

   • If <20% and the patient has not used TMP-SMX recently → prescribe TMP-SMX 160/800 mg twice daily for 3 days 2
   • If ≥20% or local data unavailable → prescribe nitrofurantoin 100 mg twice daily for 5 days or fosfomycin 3 g single dose 1

3. If symptoms persist after 2–3 days or recur within 2 weeks:

   • Obtain urine culture and susceptibility testing 3
   • Switch to a different antibiotic class for a 7-day course (avoid repeating the initial short regimen) 3
   • Reserve fluoroquinolones only for culture-proven resistance 1

Critical Pitfalls to Avoid

• Do not use citralka or any urinary alkalinizer as treatment for UTI; these agents lack antimicrobial activity and will not eradicate infection.

• Do not treat asymptomatic bacteriuria in non-pregnant, non-catheterized women; therapy provides no clinical benefit and promotes antimicrobial resistance. 1

• Do not use empiric fluoroquinolones as first-line therapy for uncomplicated cystitis because of serious adverse effects, rising global resistance, and the need to preserve their efficacy for complicated infections. 1

• Do not prescribe nitrofurantoin when eGFR is <30 mL/min/1.73 m² because adequate urinary concentrations cannot be attained. 1

• Do not use oral fosfomycin for suspected pyelonephritis or upper-tract infections due to insufficient tissue penetration. 1
