Legion (taxonomy) The legion, in biological classification, is a non-obligatory taxonomic rank within the Linnaean hierarchy sometimes used in zoology. In zoological taxonomy, the legion is: Legions may be grouped into superlegions or subdivided into sublegions, and these again into infralegions. Legions and their supe... | https://en.wikipedia.org/wiki?curid=9668061 |
Pharmacokinetics (from Ancient Greek "pharmakon" "drug" and "kinetikos" "moving, putting in motion"; see chemical kinetics), sometimes abbreviated as PK, is a branch of pharmacology dedicated to determine the fate of substances administered to a living organism. The substances of interest include any chemical xenobioti... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics One of these, the multi-compartmental model, is the most commonly used approximations to reality; however, the complexity involved in adding parameters with that modelling approach means that "monocompartmental models" and above all "two compartmental models" are the most-frequently used. The various c... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics The use of these models allows an understanding of the characteristics of a molecule, as well as how a particular drug will behave given information regarding some of its basic characteristics such as its acid dissociation constant (pKa), bioavailability and solubility, absorption capacity and distribu... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics Noncompartmental methods estimate the exposure to a drug by estimating the area under the curve of a concentration-time graph. Compartmental methods estimate the concentration-time graph using kinetic models. Noncompartmental methods are often more versatile in that they do not assume any specific comp... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics In addition, there are some tissues (such as the brain tissue) that present a real barrier to the distribution of drugs, that can be breached with greater or lesser ease depending on the drug's characteristics. If these relative conditions for the different tissue types are considered along with the ra... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics In the real world each tissue will have its own distribution characteristics and none of them will be strictly linear. If we label the drug's volume of distribution within the organism Vd and its volume of distribution in a tissue Vd the former will be described by an equation that takes into account a... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics The number of time points available in order to perform a successful NCA analysis should be enough to cover the absorption, distribution and elimination phase to accurately characterize the drug. Beyond AUC exposure measures, parameters such as Cmax (maximum concentration), Tmax(time at maximum concent... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics The change in concentration over time can be expressed as formula_2 The graph for the non-linear relationship between the various factors is represented by a curve; the relationships between the factors can then be found by calculating the dimensions of different areas under the curve. The models used ... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics Bioavailability of other delivery methods is compared with that of intravenous injection (absolute bioavailability) or to a standard value related to other delivery methods in a particular study (relative bioavailability). Once a drug's bioavailability has been established it is possible to calculate t... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics Finally, using the Henderson-Hasselbalch equation, and knowing the drug's formula_10 (pH at which there is an equilibrium between its ionized and non ionized molecules), it is possible to calculate the non ionized concentration of the drug and therefore the concentration that will be subject to absorpt... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics Chemical techniques are employed to measure the concentration of drugs in biological matrix, most often plasma. Proper bioanalytical methods should be selective and sensitive. For example, microscale thermophoresis can be used to quantify how the biological matrix/liquid affects the affinity of a drug ... | https://en.wikipedia.org/wiki?curid=9674107 |
Pharmacokinetics Recent studies show that Secondary electrospray ionization (SESI-MS) can be used in drug monitoring, presenting the advantage of avoiding animal sacrifice. "Population pharmacokinetics" is the study of the sources and correlates of variability in drug concentrations among individuals who are the target... | https://en.wikipedia.org/wiki?curid=9674107 |
