Prostate
- Poorly penetrated by most antibiotics
- Penetration is higher with a high concentration gradient, high lipid solubility, low degree of ionization, high dissociation constant, low protein binding, and small molecular size
- Fluoroquinolones are the mainstay of therapy, though there is increasing resistance
- TMP-SMX often used, but unclear if the sulfamethoxazole component actually reaches the prostate
- Minocycline, doxycycline, and macrolides achieve high levels in the prostate but are rarely indicated for the causative organisms
- Third-generation cephalosporins and carbapenems can be used
- Piperacillin, aztreonam, imipenem, and some aminoglycosides are likely useful
