Frequently Asked Questions


What is PrecisePK?

PrecisePK is a software application for therapeutic drug monitoring and the ultimate pharmacokinetic tool for both practicing medical professionals and researchers. The process of calculating an optimal dosage regimen is simplified with one custom and 15 pre-configured pharmacokinetic parameters.

How does it work?

PrecisePK provides the user with a one-compartment model to input a subject’s starting pharmacokinetic parameters, including, gender, age, body weight, height and current renal function status, along with the drug (or chemical) name, plasma clearance, absorption rate constant, volume of distribution and bioavailability.
The user is then able to input a subject’s individual dosage history through entering the dosage amount, administration method (oral, intramuscular and/or intravenous), and frequency. This feature ensures ultimate customization through providing the user to enter dosages given at uneven intervals over a period of hours or days.
Any of the subject’s information, such as subject weight, timing or dosage amount, or volume of distribution, etc., can be altered in order to see the effects on the predicted serum levels.

Who is PrecisePK for?

Pharmacologists, clinicians, researchers, analytical toxicologist, doctors, and medical professionals needing an efficient tool for precise pharmacokinetic calculations.


What groups of people does PrecisePK provide analysis for?

PrecisePK excels in all age groups, including neonates and pre-term infants, both males and females.

What is the advantage of having a shared database with your pharmacokinectics analytics software?

Having a shared program and patient database, pharmacists and healthcare professionals can share and store data seamlessly over a secure network and avoid redundancy. This makes pharmacokinetic analysis an efficient process and provides consistent recommendations.

I currently use a calculator to perform PK. Why switch to PrecisePK?

PrecisePK uses Bayesian and non-steady-state serum levels to accurately estimate the patient’s pharmacokinetic parameters. This means patients get to the optimal dosage regimen sooner. Doses given at uneven intervals are easily and accurately analyzed. And, if a serum level result looks unreasonable, Bayesian analysis handles it better.
