CYP450 Drug Interaction Magnitude Estimator

Estimate the expected magnitude of CYP450 drug-drug interactions based on inhibitor potency (weak/moderate/strong) and substrate sensitivity to predict fold-increases in AUC for dose adjustment guidance.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate the expected magnitude of CYP450 drug-drug interactions based on inhibitor potency (weak/moderate/strong) and substrate sensitivity to predict fold-increases in AUC for dose adjustment guidance

Each component has a specific meaning:

  • Inhibitor potency — The inhibitor potency recorded for the scenario being assessed.
  • Substrate sensitivity — The substrate sensitivity recorded for the scenario being assessed.

Note: Interpret the cyp450 interaction result against the thresholds and context described above.

How to Use

Enter the inhibitor potency, substrate sensitivity for the scenario you are assessing. Estimate the expected magnitude of CYP450 drug-drug interactions based on inhibitor potency (weak/moderate/strong) and substrate sensitivity to predict fold-increases in AUC for dose adjustment guidance. Use the cyp450 interaction result to inform your calculation.
