Summary
Chronic inflammation can suppress CYP450 enzymes, and IL-17A blockade may allow them to recover. Quinidine has a narrow therapeutic index, so changes in metabolism could matter. The effect is theoretical and probably small.
What this interaction means in plain words
Quinidine and Secukinumab have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Quinidine belongs to Anti Parasitic; Secukinumab belongs to Miscellaneous.
Why it happens
Cytokine normalization after IL-17A inhibition may restore CYP3A4 activity and modestly reduce quinidine exposure.
What to do
When secukinumab is started or stopped, check the quinidine response, ECG and serum level if clinically indicated. Adjust the dose only if the response or level changes.

- Is there anything I should notice while taking both?
