*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, though conflicting data about its penetration into 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
  +
  +
===Bone===
  +
  +
*Essentially all antibiotics achieve similar bone-to-serum levels, with the exception of oral Ξ²-lactams which nevertheless have no worse outcomes[[CiteRef::landersdorfer2009pe]]
  +
  +
===Eye===
  +
  +
*Ocular compartments include anterior and posterior
  +
**Anterior includes aqeous humour, and is best accessed using topical medications
  +
**Posterior includes vitreous humour, retina, and choroid, and is best accessed using intravitreal or systemic medications
  +
*Penetration of systemic antimicrobials into retina and vitreous is poor (~0 to 2%), but is better with inflammation[[CiteRef::brockhaus2019re]]
  +
**Preferred agents for vitreal penetration include [[meropenem]], [[linezolid]], and [[moxifloxacin]]
  +
**Agents that are likely effective, especially when inflammation is present, include [[vancomycin]], [[cefazolin]], [[ceftriaxone]], [[ceftazidime]], [[imipenem]], and [[trimethoprim-sulfamethoxazole]], and possible [[daptomycin]] and [[rifampin]]
  +
**Agents that do not reach adequate levels include [[ciprofloxacin]], [[levofloxacin]], [[aminoglycosides]], [[aminopenicillins]], [[piperacillin]], [[cefepime]], and [[clarithromycin]]

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, though conflicting data about its penetration into 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

Bone

  • Essentially all antibiotics achieve similar bone-to-serum levels, with the exception of oral Ξ²-lactams which nevertheless have no worse outcomes4
