Precision tools for
clinical pharmacy.
The Institute for Pharmacy provides unvarnished, data-driven frameworks for continuing professional development, alongside 15+ rigorous calculators designed for secondary care and community dispensing. No marketing, just the models.
Core Calculators
Essential kinetic models and conversion tools built strictly to national guidelines. JS is heavily sandboxed; tools do not transmit patient data.
Creatinine Clearance (CrCl)
Cockcroft-Gault equation for estimating renal function to guide drug dosing adjustments.
Opioid Dose Converter
Equianalgesic dose calculations between oral, transdermal, and parenteral opioids.
Vancomycin Kinetics
Initial dose estimation and steady-state AUC/trough adjustments for IV vancomycin.
BMI & BSA Calculator
Body Surface Area (Mosteller, DuBois) and Ideal Body Weight calculations for oncology dosing.
Phenytoin Adjustment
Winter-Tozer equation for adjusting total phenytoin levels in hypoalbuminemia or renal failure.
NNT & ARR Calculator
Calculate Absolute Risk Reduction and Number Needed to Treat from clinical trial data.
The Revalidation Reality
A 2023 audit of UK pharmacist revalidation submissions found that over 40% of peer discussions failed to document actionable changes to practice, leading to increased regulatory scrutiny.
- + Focus on reflective vs descriptive logs
- + Mandatory peer discussion structures
- + Evidence-based clinical auditing

Clinical Pitfalls
Frequent calculation errors observed in acute settings.
eGFR vs. CrCl for DOAC Dosing
The Error: Using eGFR (automatically reported by the lab, normalised to 1.73m²) to dose Direct Oral Anticoagulants (DOACs) in extremes of body weight.
The Standard: The MHRA and product characteristics mandate using the Cockcroft-Gault equation (CrCl) for DOAC dosing. Using eGFR in elderly patients weighing <50kg frequently leads to severe overdosing and bleeding events.
Incomplete Cross-Tolerance Reductions
The Error: Switching a patient between opioids using a straight equianalgesic conversion table without applying a dose reduction.
The Standard: Due to incomplete cross-tolerance at opioid receptors, the newly calculated dose should routinely be reduced by 30-50% (except when switching to methadone, which requires specialist input). Failure to reduce the dose risks fatal respiratory depression.
