Erratum: Developing mathematical models to compare and analyse the pharmacokinetics of morphine and fentanyl

In the article titled “Developing mathematical models to compare and analyse the pharmacokinetics of morphine and fentanyl” published in the Indian Journal of Anaesthesia, 2024;68(1):111–117, on page 111, in the abstract section, “using numeric analysis techniques, non-linear ordinary differential equations were used…” should be read as “using numeric analysis techniques, linear ordinary differential equations were used…”.

Similarly, on page 115, in the conclusion section, “the non-linear ordinary differential equations helped determine…” should be read as “the linear ordinary differential equations helped determine…”.

This change does not impact the conclusions of the study. The authors apologise for this oversight.
