About This Simulator
This interactive pharmacokinetic simulator for Tapering- Venlafaxine allows you to explore concentration-time profiles under different dosing scenarios. The underlying 1-compartment oral PK + Michaelis-Menten receptor occupancy (SERT / α₂-adrenergic) model characterizes the pharmacokinetics of this antidepressants (ssri, snri, nassa) following oral administration.
Use the simulator to visualize key exposure metrics including AUC (area under the curve), Cmax (peak concentration), and Ctrough (trough concentration).
Built with PKPDBuilder — an AI-powered platform that transforms published pharmacometric literature into interactive, deployable Shiny applications. No coding required.
