My spouse doesn't like it the way I do but what I truly like performing is caving but I don't have the time lately.

The '''initial volume of distribution''' is a pharmacological term used to quantify the distribution of a drug throughout the body relatively soon after oral or intravenous dosing of a drug and prior to the drug reaching a steady state equilibrium. Following distribution of the drug, measurement of blood levels indicate the [[apparent volume of distribution]]. Calculation of the initial volume of distribution is the same calculation as that for the apparent volume of distribution, given by the equation:

:::::::<math>{V_{D}} = \frac{\mathrm{total \ amount \ of \ drug \ in \ the \ body \ per \ body \ weight \ unit \ (Kg) \ (i.e. Dose)}}{\mathrm{drug \ blood \ concentration}}</math>

Therefore the dose required to give a certain plasma concentration can be determined if the VD for that drug is known. The VD is not a real volume; it is more a reflection of how a drug will distribute throughout the body depending on several physicochemical properties, e.g. solubility, charge, size, etc. The VD may also be used to determine how readily a drug will displace into the body tissue compartments relative to the blood:

:::::::<math>{V_{D}} = {V_{P}} + {V_{T}} \left(\frac{fu}{fu_{t}}\right)</math>

Where:

VP = plasma volume

VT = apparent tissue volume

fu = fraction unbound in plasma

fuT = fraction unbound in tissue
