Summary
Ritonavir inhibits CYP3A4 and P-glycoprotein and may raise linagliptin levels modestly, though linagliptin has a wide safety margin. Protease inhibitors can also cause insulin resistance and hyperglycemia, which may offset glucose control.
What this interaction means in plain words
Linagliptin and Ritonavir have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Linagliptin belongs to Endocrine; Ritonavir belongs to Anti Virals.
Why it happens
Ritonavir inhibits CYP3A4 and P-gp, slightly increasing linagliptin exposure, while protease inhibitors can independently impair insulin sensitivity.
What to do
No linagliptin dose change is generally needed. Monitor blood glucose during ritonavir therapy and adjust antidiabetic treatment as required.
What to ask your pharmacist
- Is there anything I should notice while taking both?
