Every Tool a Clinical
Pharmacist Needs

Built on peer-reviewed pharmacokinetic equations and the 2020 ASHP/IDSA/SIDP vancomycin guidelines. No guesswork — just evidence-based calculations.

Core Engine

One-Compartment PK Model

Steady-state IV intermittent infusion model with Cockcroft–Gault CrCl estimation. Calculates Vd, ke, half-life, peak, trough, and AUC24 from patient-specific parameters.

Advanced

Bayesian MAP Estimation

Input 1–2 measured serum levels to update population PK priors with Maximum A Posteriori Bayesian estimation. Refines individual CL and Vd for more accurate dosing.

Advanced

Sawchuk–Zaske Method

Two-level Sawchuk–Zaske analysis for patient-specific pharmacokinetic parameter estimation. Calculates individualized CL, Vd, and ke from measured peak and trough levels.

Guidelines-Based

AUC24 & Trough Targeting

Target AUC24/MIC 400–600 mg·h/L per 2020 ASHP/IDSA/SIDP guidelines, or traditional trough-based monitoring. Visual band indicators show therapeutic, subtherapeutic, and supratherapeutic ranges.

Smart

Dose Optimization Engine

Generates multiple dose/interval combinations ranked by target attainment. Supports back-calculation from desired AUC24 or trough. Applies RxToDose infusion time rules automatically.

Workflow

Patient History

Save and revisit previous patient calculations with full PK results. Quickly compare regimens across visits or load a prior case to adjust parameters.

Safety

Renal Trend Monitoring

Track SCr changes over time with automatic rate-of-change analysis. Alerts for rapidly rising creatinine (potential AKI) where steady-state PK assumptions may not hold.

Visual

Concentration–Time Charts

Interactive concentration-time curve visualization showing peak, trough, and therapeutic window across multiple dosing intervals. Exportable results for clinical documentation.

Workflow

From Patient Data to
Optimized Dose

A streamlined four-step workflow designed for clinical efficiency.

01

Enter Patient Parameters

Input age, sex, actual body weight, height, and serum creatinine. VancoPro calculates CrCl via Cockcroft–Gault and estimates population-based vancomycin clearance.

Supports IBW/ABW/AdjBW selection, obese patient adjustments, and optional renal trend tracking with two SCr values.

02

Set Regimen & Targets

Enter the proposed dose and interval, or let the dose optimizer suggest regimens. Choose between AUC24 (400–600) or trough (15–20 mg/L) monitoring targets.

Infusion time is auto-calculated using RxToDose rules or manually overridden. Supports Q8h, Q12h, Q24h, and custom intervals.

03

Add Measured Levels (Optional)

For patients with measured drug levels, enter 1–2 serum concentrations with collection times to enable Bayesian MAP or Sawchuk–Zaske individualization.

Accepts pre-dose trough, post-infusion peak, or any random level with time since infusion start.

04

Review PK Analysis

Instantly view patient-specific Vd, CL, ke, half-life, Cmax, Ctrough, AUC24, and AUC/MIC. Color-coded band indicators flag therapeutic vs. out-of-range values.

Concentration-time chart visualizes the full dosing interval. Share or save results to patient history.

Evidence-Based

Grounded in Peer-Reviewed
Clinical Science

Every calculation in VancoPro is derived from established pharmacokinetic literature and current clinical guidelines.

Who Uses VancoPro

Built for Healthcare
Professionals

Clinical Pharmacists

Optimize vancomycin regimens at the bedside. Integrate Bayesian individualization with measured levels for complex patients.

Physicians & NPs

Quick dose verification and AUC24 target assessment without leaving the patient's side. Supports shared decision-making.

Pharmacy Students

Learn PK principles through hands-on calculation. Visualize how patient parameters affect drug exposure and dosing.

ICU & ID Teams

Manage complex patients with renal impairment, obesity, or AKI. Renal trend monitoring flags unstable kidney function.
