    DOSE IN RENAL IMPAIRMENT <\/H3>

    GFR (mL\/MIN)<\/H4>
  • 20 to 50 &nbsp &nbsp : Dose as in normal renal function, but avoid if possible
  • 10 to 20 &nbsp &nbsp : Dose as in normal renal function, but avoid if possible
  • <10 &nbsp &nbsp &nbsp &nbsp &nbsp : Dose as in normal renal function, but only use if on dialysis

    DOSE IN PATIENTS UNDERGOING RENAL REPLACEMENT THERAPIES <\/H3>
  • CAPD &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp:Slightly dialysed. Dose as in GFR <10 mL\/min <\/p>\n
  • HD &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp &nbsp :Not dialysed. Dose as in GFR <10 mL\/min
  • HDF\/high flux &nbsp :Unknown dialysability. Dose as in GFR <10 mL\/min
  • CAV\/VVHD &nbsp &nbsp &nbsp:Slightly dialysed. Dose as in GFR 10 to 20 mL\/min

    IMPORTANT DRUG INTERACTIONS <\/H3>Potentially hazardous interactions with other drugsACE inhibitors and angiotensin-II antagonists: antagonism of hypotensive effect; increased risk of nephrotoxicity and hyperkalaemia\n
  • Analgesics: avoid concomitant use of 2 or more NSAIDs, including aspirin (increased side effects); avoid with ketorolac (increased risk of side effects and haemorrhage)\n
  • Antibacterials: possibly increased risk of convulsions with quinolones\n
  • Anticoagulants: effects of coumarins enhanced; possibly increased risk of bleeding with heparins and coumarins\n
  • Antidepressants: increased risk of bleeding with SSRIs and venlafaxineAntidiabetic agents: effects of sulphonylureas enhanced\n
  • Anti-epileptics: possibly increased phenytoin concentration\n
  • Antivirals: increased risk of haematological toxicity with zidovudine; concentration possibly increased by ritonavir\n
  • Ciclosporin: may potentiate nephrotoxicity Cytotoxic agents: reduced excretion of methotrexate; increased risk of bleeding with erlotinib\n
  • Diuretics: increased risk of nephrotoxicity; antagonism of diuretic effect; hyperkalaemia with potassium-sparing diuretics\n
  • Lithium: excretion decreased Pentoxifylline: increased risk of bleeding Probenecid: excretion reduced by probenecid\n
  • Tacrolimus: increased risk of nephrotoxicity
