## Drug Purity given Rate of Administration and Dosing Interval Solution

STEP 0: Pre-Calculation Summary
Formula Used
Drug Purity = (Drug Rate*Dosing Interval)/(Administered Dose*Bioavailability)
This formula uses 5 Variables
Variables Used
Drug Purity - The Drug Purity is the measurement of the quantity of a prevalent component of a drug substance when only that component is present.
Drug Rate - (Measured in Kilogram per Second) - Drug Rate of Administration is the amount of drug administered in a particular interval of time.
Dosing Interval - (Measured in Second) - The Dosing Interval is the time between drug dose administrations.
Administered Dose - (Measured in Kilogram) - Administered Dose is the amount of drug administered for a pharmacological response.
Bioavailability - The Bioavailability is the systemically available fraction of a drug.
STEP 1: Convert Input(s) to Base Unit
Drug Rate: 45 Kilogram per Second --> 45 Kilogram per Second No Conversion Required
Dosing Interval: 44 Second --> 44 Second No Conversion Required
Administered Dose: 3.5 Microgram --> 3.5E-09 Kilogram (Check conversion here)
Bioavailability: 12.5 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula

Saponification value
Saponification Value = Molecular weight of KOH*(Volume of blank-Volume of Actual solution)*Normality of solution/Weight of sample taken
Fraction of Drug Unbound in Tissue given Apparent Tissue Volume
Fraction Unbound in Tissue = (Fraction Unbound in Plasma*Apparent Tissue Volume)/(Volume of Distribution-Plasma Volume)
Secretion Rate of Drug
Secretion Rate of Drug = (Renal Clearance*Plasma Concentration)-(Filtration Rate)+(Reabsorption Rate of Drug)
Reabsorption Rate of Drug
Reabsorption Rate of Drug = ((Renal Clearance*Plasma Concentration)+Filtration Rate+Secretion Rate of Drug)
Filtration Rate of Drug
Filtration Rate = ((Renal Clearance*Plasma Concentration)+Reabsorption Rate of Drug-Secretion Rate of Drug)
Relative Bioavailability of Drug
Relative Bioavailability = (Area under curve Dosage A/Area under curve Dosage B)*(Dose Type B/Dose Type A)
Acid Value of KOH
Acid Value = Molecular weight of KOH*Volume of solution koh*Normality of solution/Weight of sample taken
Drug Purity given Rate of Administration and Dosing Interval
Drug Purity = (Drug Rate*Dosing Interval)/(Administered Dose*Bioavailability)
Rate of Administration of Drug given Dosing Interval
Drug Rate = (Administered Dose*Bioavailability*Drug Purity)/Dosing Interval
Drug Purity given Administrative Dose and Effective Dose
Drug Purity = Effective Dose/(Administered Dose*Bioavailability)
Drug Loading Efficiency = Weight of drug in nanoparticles/Weight of the Nanoparticles*100
Encapsulation Efficiency
Encapsulation Efficiency = Weight of drug in nanoparticles/Weight of feeding drug*100
Renal Clearance of Drug
Renal Clearance = Drug Amount Excreted Unchanged in Urine/Area Under Curve
Concentration of Drug given Rate of Infusion of Drug
Concentration of Drug = Rate of Infusion/Volume of Plasma Cleared
Rate of Infusion of Drug
Rate of Infusion = Volume of Plasma Cleared*Concentration of Drug
Median Lethal Dose using Therapeutic Index
Median Lethal Dose = (Median Effective Dose*Therapeutic Index)
Margin of Safety of Drugs
Margin of Safety = Toxic Dose Response/Effective Dose Response
Effective Dose using Therapeutic Index
Median Effective Dose = Median Lethal Dose/Therapeutic Index
Therapeutic Index
Therapeutic Index = Median Lethal Dose/Median Effective Dose
Absorption Half-Life of Drug
Absorption Half Life = ln(2)/Absorption Rate Constant
Drug Rate Entering Body
Absorption Rate Constant = ln(2)/Absorption Half Life
Concentration of Drug using Volume of Distribution
Concentration of Drug = Dose/Volume of Distribution
Apparent Volume of Drug Distribution
Volume of Distribution = Dose/Concentration of Drug
Tablet Dosage
Number of tablet = Desired dosage/Stock strength
Easter Value
Easter Value = Saponification Value-Acid Value

## Drug Purity given Rate of Administration and Dosing Interval Formula

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

## What is Pharmacokinetics?

Pharmacokinetics is a branch of pharmacology dedicated to determine the fate of substances administered to a living organism. The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc. It attempts to analyze chemical metabolism and to discover the fate of a chemical from the moment that it is administered up to the point at which it is completely eliminated from the body. Pharmacokinetics is the study of how an organism affects a drug, whereas pharmacodynamics (PD) is the study of how the drug affects the organism. Both together influence dosing, benefit, and adverse effects, as seen in PK/PD models.

## How to Calculate Drug Purity given Rate of Administration and Dosing Interval?

Drug Purity given Rate of Administration and Dosing Interval calculator uses Drug Purity = (Drug Rate*Dosing Interval)/(Administered Dose*Bioavailability) to calculate the Drug Purity, The Drug purity given rate of administration and dosing interval formula is defined as the ratio of the rate of administration of the drug with dosing interval to the administrative dose and a systemically available fraction of a drug. Drug Purity is denoted by Q symbol.
