Summary
Saquinavir, a CYP3A4 and P-gp inhibitor, may modestly increase linagliptin exposure, which is unlikely to be clinically important. Protease inhibitors may also cause hyperglycemia through insulin resistance.
What this interaction means in plain words
Linagliptin and Saquinavir have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Saquinavir inhibits CYP3A4 and P-gp, and protease inhibitors can independently reduce insulin sensitivity.
What to do
No dose adjustment of linagliptin is usually required. Monitor blood glucose during saquinavir therapy.
