Simulate PK/PD profiles using ODE and analytical models.
Example
ODE based model.

Supported analytical models
We are working to support all the standard analytical models.
- One-compartment with IV infusion
- One-compartment with IV infusion and oral absorption
- Two-compartment with IV infusion
- Two-compartment with IV infusion and oral absorption
- Three-compartmental models
