Bioavailability of Drug Dose given Loading Dose Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bioavailability Of drug dose = (Volume Of Distribution dose*Target Plasma Concentration)/Loading Dose
F% = (V_d*C_p)/LD
This formula uses 4 Variables

Variables Used

Bioavailability Of drug dose - The Bioavailability Of drug dose is describe the fraction or percentage of administration drug that reaches the systemic circulation in an unchanged and active form.
Volume Of Distribution dose - (Measured in Cubic Meter) - The Volume of distribution dose is used to describe the apparent distribution of a drug in the body relative to its concentration in the plasma.
Target Plasma Concentration - (Measured in Kilogram per Cubic Meter) - The Target Plasma Concentration is refer to the desired or optimal concentration of a drug in the bloodstream at a specific time after the administration.
Loading Dose - (Measured in Kilogram) - The Loading Dose is the initial dose of a drug that is administered to achieve a desired plasma concentration.

STEP 1: Convert Input(s) to Base Unit

Volume Of Distribution dose: 50 Liter --> 0.05 Cubic Meter (Check conversion here)
Target Plasma Concentration: 30 Milligram per Liter --> 0.03 Kilogram per Cubic Meter (Check conversion here)
Loading Dose: 50 Milligram --> 5E-05 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F% = (V_d*C_p)/LD --> (0.05*0.03)/5E-05

Evaluating ... ...

F% = 30

STEP 3: Convert Result to Output's Unit

30 --> No Conversion Required

Dose of drug administered orally

Go Dose Non-Intravenous = (Area under Curve Non-Intravenous*Dose Intravenous)/(Area under Curve Intravenous*Bioavailability of Drug)

Dose of drug administered intravenous

Go Dose Intravenous = (Bioavailability of Drug*Area under Curve Intravenous*Dose Non-Intravenous)/Area under Curve Non-Intravenous

Dose of A type drug

Go Dose Type A = (Area under curve Dosage A/Area under curve Dosage B)*(Dose Type B/Relative Bioavailability)

Dose of B type drug

Go Dose Type B = (Relative Bioavailability*Dose Type A)*(Area under curve Dosage B/Area under curve Dosage A)

Administrative dose given rate of administration and dosing interval

Go Administered Dose = (Drug Rate of Administration*Dosing Interval)/(Bioavailability*Drug Purity)

Previous Rate of Drug Dose given Revised Dose

Go Previous Rate of Dose = (Revised Dose*Measured Steady State Concentration Plasma)/(Target Steady State Plasma Concentration)

Dosing interval given rate of administration

Go Dosing Interval = (Administered Dose*Bioavailability*Drug Purity)/Drug Rate of Administration

Revised Dose

Go Revised Dose = Previous Rate of Dose*Target Steady State Plasma Concentration/Measured Steady State Concentration Plasma

Loading Dose

Go Loading Dose = (Target Plasma Concentration*Volume Of Distribution dose)/Bioavailability Of drug dose

Maintenance Dose

Go Maintenance Dose = Drug Clearance*Target Plasma Concentration/Bioavailability Of drug dose

Dose given volume of distribution and area under curve

Go Dose = Volume of Distribution*Elimination Rate Constant*Area Under Curve

Administrative Dose given Drug Purity

Go Administered Dose = Effective Dose/(Drug Purity*Bioavailability)

Effective dose given drug purity

Go Effective Dose = Drug Purity*Bioavailability*Administered Dose

Adult Dose of Drug by Clark's Equation in Micrograms

Go Adult Dose = Pediatric Dosage/(Weight of Patient in microgram/68)

Clark's Equation of Dosage in Microgram

Go Pediatric Dosage = Adult Dose*(Weight of Patient in microgram/68)

Dosing interval given average plasma concentration

Go Dosing Interval = Area Under Curve/Average Plasma Concentration

Adult Dose of Drug by Clark's Equation

Go Adult Dose = Pediatric Dosage/(Weight of Patient/150)

Weight of Patient by Clark's equation

Go Weight of Patient = (Pediatric Dosage/Adult Dose)*150

Clark's Equation of Dosage

Go Pediatric Dosage = Adult Dose*(Weight of Patient/150)

Weight of Patient in Kilograms by Clark's equation

Go Weight of Patient = (Pediatric Dosage/Adult Dose)*68

Amount of drug administered given apparent volume

Go Dose = Volume of Distribution*Concentration of Drug

Amount of drug in given volume of plasma

Go Concentration of Drug = Dose/Volume of Distribution

Administrative dose given effective dose and bioavailability

Go Administered Dose = Effective Dose/Bioavailability

Effective dose given bioavailability and administrative dose

Go Effective Dose = Bioavailability*Administered Dose

Amount of drug administered given area under curve

Go Dose = Volume of Plasma Cleared*Area Under Curve

Bioavailability of Drug Dose given Loading Dose Formula

Bioavailability Of drug dose = (Volume Of Distribution dose*Target Plasma Concentration)/Loading Dose

How does pharmacokinetics deal with the drug dose difference ?

In medicine, the treatment for most conditions uses various pharmacological medications. For each of these individual medications, the route of administration, appropriate dosage, and frequency of use are determined by the medication’s pharmacokinetics (PK). Pharmacokinetics is the relationship between an administered dose of a drug and its measured concentration within the body. An individual medication’s PK is governed by how it moves within the body through absorption, bioavailability, distribution, metabolism, and excretion.

The characteristics that define an individual medication’s PK can help determine the loading dose. While a patient takes a specific drug to achieve the therapeutic benefit, the drug must reach a certain steady-state concentration. Typically, for any medication, five to seven half-lives are required for this to be achieved.
