1. What is the Administered Dose Formula?

The Administered Dose formula calculates the amount of drug administered for a pharmacological response based on drug rate of administration, dosing interval, bioavailability, and drug purity.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ D_a = \frac{V_a \times \tau}{B \times Q} \]

Where:

\( D_a \) — Administered Dose (kg)
\( V_a \) — Drug Rate of Administration (kg/s)
\( \tau \) — Dosing Interval (s)
\( B \) — Bioavailability
\( Q \) — Drug Purity

Explanation: The formula calculates the administered dose by considering the rate and duration of drug administration, adjusted for bioavailability and purity factors.

3. Importance of Administered Dose Calculation

Details: Accurate administered dose calculation is crucial for ensuring proper drug dosing, achieving therapeutic effects, and avoiding toxicity in pharmacological treatments.

4. Using the Calculator

Tips: Enter drug rate of administration in kg/s, dosing interval in seconds, bioavailability, and drug purity. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is drug bioavailability?
A: Bioavailability refers to the fraction of an administered drug that reaches systemic circulation and is available for pharmacological activity.

Q2: Why is drug purity important in dose calculation?
A: Drug purity affects the actual amount of active pharmaceutical ingredient, ensuring accurate dosing and therapeutic efficacy.

Q3: How does dosing interval affect administered dose?
A: Longer dosing intervals typically require larger individual doses to maintain therapeutic drug levels over time.

Q4: What units should be used for drug rate of administration?
A: The calculator uses kg/s, but conversions from other units (mg/h, etc.) may be necessary before input.

Q5: When should this formula be used?
A: This formula is particularly useful in pharmacokinetic studies and when designing drug administration regimens for clinical applications.
