"Webb12 juni 2024 · It is defined as the volume in which the amount of drug would need to be uniformly distributed to produce the observed blood concentration. Volume of distribution may be increased by renal failure (due to fluid retention) and liver failure (due to altered body fluid and plasma protein binding). Conversely it may be decreased in dehydration. " - Protein binding and volume of distribution

Webb1 feb. 2004 · The degree of protein binding is inversely related to the volume of distribution [19], thus the decreased protein binding may also partly explain the increased V d for flucloxacillin of 0.45 l kg −1 (versus 0.13 l kg −1 in adults). The additional volume of the CPB circuit may also explain the increased V d for flucloxacillin. http://www.turkupetcentre.net/petanalysis/model_distribution_volume.html

Fitting the distribution of refractive indices with a kernel smoothing function allows for the visualization of the probability density in a multivariant setting and confirms the presence of two populations with refractive index maxima at 1.3361 and 1.3411.

WebbPlasma protein binding refers to the degree to which medications attach to proteins within the blood. A drug's efficiency may be affected by the degree to which it binds. The less bound a drug is, the more efficiently it can traverse or diffuse through cell membranes. WebbResults: The protein and lipid binding components were parameterized using a dataset containing human in vitro and in vivo parameters for 63 drugs. The resulting equation explains ~84% of the variance in the log of the volume of distribution with an average fold-error of 1.6, with 3 outliers.
