Ciprofloxacin/Cipro


- Discussion:
    - broad spectrum quinolone against gm pos & neg organisms;
    - poor Activity against: enterococci, non entero strep, anaerobes;
    - adult:
          - PO: 250, 500, or 750 mg PO q12 hr;
          - IV: 200-400 mg IV q12 hr;

- Cautions:
    - at present sucralfate should not be used if fluoroquinolone antibiotics are required;
    - watch for hallucinations;
    - will incr levels of theophyllin;
    - antacids (Mg & Al) and ferrous sulfate will decr levels of Cipro, while probeneicid will incr Cipro levels;
    - will increase PT times in patients taking coumadin;
    - may affect phenytoin levels;
    - equivocal evidence for Achilles tendon rupture in rare cases;
    - contra-indicated in children: 
    - may be toxic to immature cartilage (evidence in puppies), but has been used to treat pulmonary infections in children w/ CF will no apparent ill effects; 
    - note: good diffusion from blood into CSF only w/ inflammation; ratio of CSF to blood level (%): normal meninges: 5; inflammed meninges: 5-37;
    - dosing regimens for patients with renal insufficiency:
          - dose for 70kg Adult (gm/dosing interval in hrs)
          - PO: CrCl: >80: 0.5-.75/12; CrCl:50-79:0.5-.75/8; CrCl:30-49: 0.5-.75/12; CrCl:10-29: 0.5-.75/18-24;
          - IV: CrCl: >80: 0.2-.4/12; CrCl:50-79:0.2-.4/8; CrCl:30-49: 0.2-.4/12; CrCl: 10-29: 0.5-.75/18-24;
