How does the loading dose achieve quick clinical response?
Loading doses are a means to quicks achieve therapeutic drug concentrations or prompt an immediate clinical response. Loading doses are larger than maintenance doses and are usually administered as a single bolus, although some drugs (eg, amiodarone or digoxin) may require multiple loading doses administered over several hours to days.[1] An intravenous loading dose of phenytoin, on the other hand, should be administered as a single dose. Medications with shorter half-lives (eg, heparin for treating pulmonary embolism) may also require a loading dose to achieve their therapeutic effect immediately.
How to Calculate Volume of Dose Distribution given Loading Dose?
Volume of Dose Distribution given Loading Dose calculator uses Volume Of Distribution dose = (Loading Dose*Bioavailability Of drug dose)/Target Plasma Concentration to calculate the Volume Of Distribution dose, The Volume of Dose Distribution given Loading Dose formula is defined as the ratio of the product of the loading dose and bioavailability of drug dose to the target plasma concentration. Volume Of Distribution dose is denoted by Vd symbol.
How to calculate Volume of Dose Distribution given Loading Dose using this online calculator? To use this online calculator for Volume of Dose Distribution given Loading Dose, enter Loading Dose (LD), Bioavailability Of drug dose (F%) & Target Plasma Concentration (Cp) and hit the calculate button. Here is how the Volume of Dose Distribution given Loading Dose calculation can be explained with given input values -> 4.5E+10 = (5E-05*0.9)/0.03.
