Renal adjustments in CKD and AKI 😏 Acute kidney injury is not very cute 💧 Most drugs, particularly water-soluble drugs and their metabolites, are eliminated largely by the kidneys in urine. ⭐️ It is important to know which drugs require dose adjustments to prevent accumulation and toxicity in patients with chronic kidney disease (CKD) as well as those with acute kidney injury. 🤔 Things to keep in mind when renally adjusting medications: 👉🏻 Use estimated GFR or CrCl to determine drug dosing 👉🏻 If the patient is on hemodialysis, the type of HD will also determine drug dosing 👉🏻 CrCl should be monitored periodically in patients with AKI to determine if doses need to be adjusted when CrCl improves 👉🏻 Some medications require individualized therapy (ex: serum drug level monitoring, vital signs, adverse effects) when dose adjusting
Antibiotics are commonly used to treat infections. When considering what dose to prescribe to a patient, it is important to evaluate the patient’s renal function as many antibiotics are excreted by the kidney.
It is recommended to study the list of antibiotics that do NOT require renal dose adjustments rather than a list of the ones that do (as it can get very long and overwhelming).
