PharmCalc

Calculation tool to assist clinicians in designing efficacious dosage regimes

The PharmCalc app harnesses modern technology to provide a time-saving means of performing common pharmacy calculations thereby assisting the pharmacist in the design and validation of dosage regimes that are efficacious and minimally toxic. The computational method allows for easy adjustment of calculation parameters, practically instantaneously, without having to go through the tedious process of re-calculating by hand.

This app version of PharmCalc provides an easy means of calculating Loading and Maintenance doses for routinely used drugs such as Digoxin and Theophylline. It also features a Gentamicin dosing calculator.

The project is founded on well established literature with each online tool outlining the calculations and references used.
