Acute bacterial prostatitis is treated with which antibiotic class?

• A. Amoxicillin
• B. Macrolides
• C. Fluoroquinolones
• D. Cephalexin

Answer: (C)

The key idea is choosing an antibiotic that reaches and remains active in prostatic tissue. Fluoroquinolones are ideal for this because they achieve high concentrations in the prostate and are effective against the common Gram-negative bacteria that cause acute bacterial prostatitis, such as E. coli. That combination of good tissue penetration and appropriate antimicrobial spectrum makes them the preferred first-line option. Amoxicillin and cephalexin often have poorer penetration into prostatic tissue and may not reliably cover the typical pathogens in prostatitis. Macrolides generally do not provide reliable activity against the common uropathogens involved in acute prostatitis and also don’t penetrate the prostate as well. Therefore, fluoroquinolones best fit both the penetration and spectrum needs for this condition. Examples include ciprofloxacin and levofloxacin.
