Can you give gentamicin in renal failure?

If creatinine is not known – give an initial dose of 5 mg/kg gentamicin (maximum 400 mg) or, if patient has Chronic Kidney Disease (CKD) 5, give 2.5 mg/kg (maximum 180 mg) on advice of senior staff. Calculate the dose using actual body weight except in pregnancy where the booking weight should be used.

Is gentamicin renally dosed?

Dosing interval and monitoring Gentamicin is cleared predominantly via the kidneys and the dosage interval needs to be increased in patients with impaired renal function.

What is frequency of gentamicin dosing?

Synergy regimens(e.g., with beta lactam antibiotics for endocarditis), involve 1mg/kg of intravenous gentamicin being administered every eight hours. Pre-dose (trough) gentamicin levels should be checked after 24 hours and then twice weekly (target <1mg/L).

How do you give gentamicin on dialysis?

The FDA-approved regimen for adults undergoing hemodialysis consists of the administration of 1 to 1.7 mg/kg of gentamicin at the end of each dialysis period.

Why aminoglycosides are contraindicated in renal failure?

[5–7] Because aminoglycosides have a narrow therapeutic index, optimization of therapy to minimize risk of toxicity to residual renal function or vestibular toxicity is important for patients with renal failure who have prolonged exposure to the drug.

Why are aminoglycosides contraindicated in patients with kidney failure?

Regular courses of aminoglycoside antibiotics may cause subclinical kidney damage leading to chronic kidney disease (CKD). This can manifest at the level of the glomerulus (causing decreased glomerular filtration rate, GFR) and the tubules (causing altered excretion of electrolytes).

What is extended interval dosing?

Extended-interval aminoglycoside therapy (also known as once-daily aminoglycosides, single daily aminoglycoside dosing, consolidated or high-dose aminoglycoside therapy) utilizes a higher weight-based dose administered at an extended interval (every 24 hours for those with normal renal function and longer for those …

Why should gentamicin be given slowly?

If gentamicin is administered during or immediately after surgery, the neuromuscular blockade may be enhanced and prolonged if non-depolarising muscle relaxants are used. These interactions may cause neuromuscular blockage and respiratory paralysis.

How much hemodialysis is gentamicin removed?

Most references agree that approximately 50% of gentamicin is removed during an 8 hour hemodialysis session (Table 1). Typical hemodialysis sessions are 4 hours. Therefore, less than 50% of the drug may be removed.

When should I take gentamicin levels?

Gentamicin levels should be taken 6-14 hours after the start of the infusion. For a daily dose of 5mg/kg/day the Urban-Craig nomogram can be used. Gentamicin levels should be taken 8-12 hours after the dose.

Why is gentamicin nephrotoxic?

Gentamicin induces nephrotoxicity by inhibiting protein synthesis in renal cells that specifically causes necrosis of cells in the renal proximal tubule, resulting in acute tubular necrosis, followed by acute renal failure.

What are the contraindications of gentamicin?

Who should not take GENTAMICIN SULFATE?

  • low amount of calcium in the blood.
  • dehydration.
  • a type of movement disorder called parkinsonism.
  • myasthenia gravis, a skeletal muscle disorder.
  • ringing in the ears.
  • disorder of nerve that controls hearing and balance.
  • decreased kidney function.
  • sensation of spinning or whirling.
