With the Free Online Pharmacokinetic Calculator, you can enter your substance information and dosage preferences for learning purposes.
This calculator is a mathematical tool that estimates blood levels over time based on user-provided input. It performs concentration and decay calculations using basic pharmacokinetic principles.
This calculator is a purely theoretical and academic model and not a medical tool. It is provided for educational purposes only and is not a substitute for professional medical advice, diagnosis, or treatment. Do not use it to make dosing or treatment decisions. Use at your own risk.
Instructions
Substance Information
Substance Name: Enter any label or identifier for reference purposes only.
Administration Type: Select a theoretical administration route to apply a corresponding absorption model.
Medication Concentration: Enter the concentration of the substance. The unit adapts automatically to the selected administration type.
Pharmacokinetic Properties
Half-life: Enter the half life value and select the appropriate time unit.
Bioavailability (%): Enter a bioavailability percentage.
Dosing Information
Target Weekly Systemic Dose: Enter the amount used for the calculation per selected time period.
Preferred Administration Interval: Select the time interval used for the calculation model.
Calculated Amount Per Interval: This value shows the mathematically calculated amount per selected interval based solely on the entered concentration and total amount values.
Duration: Define the total calculation period in days or weeks. An extended duration option is available for long term simulations.
Calculate: Click the calculate button to generate the numerical results.
Results: The calculator returns calculated concentration values over time, including an averaged level across the selected duration. A graphical curve visualizes the accumulation and decay based on the mathematical model. (No recommendations, conclusions or usage instructions are provided.)
Download Button: With one click you can save the result as an image on your device. The image format is optimized and recommended because the tool's result view can appear less ideal on narrow screens depending on the device.
Notice for Using the Tool
This calculator does not provide medical advice and does not replace professional consultation. It does not determine appropriate amounts, intervals or suitability for any substance or individual.
All results are mathematical estimates based solely on the values entered by the user. Interpretation and real world application require qualified professional expertise.
Do not make changes related to medication or health related decisions without consulting a licensed healthcare professional.
