Pharmacokinetics of terbutaline in chronic kidney disease.
Trial report in European journal of clinical pharmacology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeIn healthy individuals upwards of 90 % of an injected dose of terbutaline is excreted in the urine. The purpose of this study is to determine the pharmacokinetic properties of terbutaline in patients with severe renal impairment as defined by a glomerular filtration rate (GFR) below 30 mL/min.
methodsTen patients were included in the study. GFR was measured with Cr-EDTA clearance. They were given an intravenous injection of 0.500 mg of terbutaline. Blood samples were collected at intervals for 60 h and urine samples were collected for 96 h. The concentration of terbutaline in the blood and in the urine was used to calculate pharmacokinetic parameters.
resultsIn patients with normal renal function the total clearance of terbutaline is 2.23-3 mL/min/kg. In our population the total clearance of terbutaline was found to be 1.72 (SD: 0.49) mL/min/kg of which approximately 15 % (0.25 mL/min/kg) was renal clearance. We calculated a distribution volume at steady state of 0.74 (SD: 0.22) L/kg with a terminal half-life of 7.93 (SD: 4.06) hours. The mean residence time (MRT) was 8.35 (SD: 4.93) hours.
conclusionsIn healthy individuals the excretion of terbutaline is foremost renal but this study shows that severe renal impairment does not lower the total clearance of terbutaline to a degree that might be expected from the Cr-EDTA clearance. However, more research is needed to determine if dosage adjustment is warranted in patients with CKD.
