In 1980s, vancomycin with a purity > 90% was available, and kidney toxicity defined by an increase in serum creatinine of at least 0.5 mg/dL occurred in only about 5% of patients. [36] But dosing guidelines from the 1980s until 2008 recommended vancomycin trough concentrations between 5 and 15 μg/mL. [37]
For the first episode of recurrent C. difficile infection, the 2017 IDSA guidelines recommend oral vancomycin at a dose of 125 mg four times daily for 10 days if metronidazole was used for the initial episode. If oral vancomycin was used for the initial episode, then a prolonged oral vancomycin pulse dose of 125 mg four times daily for 10–14 ...
Once-daily dosing of aminoglycoside is sufficient to achieve peak plasma concentration for a clinical response without kidney toxicity. Meanwhile, for antibiotics with low volume distribution (vancomycin, teicoplanin, colistin), a loading dose is required to achieve an adequate therapeutic level to fight infections.
There are various forms, [2] and some drugs may affect kidney function in more than one way. Nephrotoxins are substances displaying nephrotoxicity. Nephrotoxicity should not be confused with some medications predominantly excreted by the kidneys needing their dose adjusted for the decreased kidney function (e.g., heparin, lithium).
For example, steady-state concentrations of drugs eliminated mostly by the kidney are usually greater in patients with kidney failure than they are in patients with normal kidney function receiving the same drug dosage. Population pharmacokinetics seeks to identify the measurable pathophysiologic factors and explain sources of variability that ...
Since the syndrome is due to the accumulation of chloramphenicol, the signs and symptoms are dose related. [10] According to Kasten's review published in the Mayo Clinic Proceedings, a serum concentration of more than 50 μg/mL is a warning sign, [10] while Hammett-Stabler and John states that the common therapeutics peak level is 10-20 μg/mL and is expected to achieve after 0.5-1.5 hours of ...
"Hopefully, we can continue to get in people's living rooms and entertain them the way we have over the last seven years," he says of the future of the Dutton universe
