How AUC Is Calculated

The trapezoidal method estimates the area under the concentration–time curve between two time points. Enter the drug concentration at two different time points along with their corresponding times.

Formula: AUC = [(C₁ + C₂) × (t₂ − t₁)] / 2

``` **Example:** If C₁ = 10 mg/L, C₂ = 5 mg/L, t₁ = 0 h and t₂ = 4 h, the calculator gives **AUC = 30 mg·h/L**. This version is standalone and can be embedded into a WordPress Custom HTML block.
