Why this happens
Naproxen is an NSAID that thins the blood slightly by affecting platelets and can irritate the stomach lining. Quinine can also lower platelet counts in some people, leading to an additive effect on bleeding risk. Both drugs have the potential to affect the electrical activity of the heart (prolonging the QT interval), though this is rare at standard doses.
What you should do
Use this combination with caution. If you have a history of stomach ulcers, heart rhythm problems, or bleeding disorders, speak to your doctor before taking them together. Seek medical advice if you notice unusual bruising, black tarry stools, or if you feel dizzy or notice a fluttering sensation in your chest.

Traitement et médicaments
Can I take Bisoprolol and Trimbow pmdi // pressurised inhalation together?
Bisoprolol and Trimbow (which contains formoterol) work in opposite ways on the airways. Bisoprolol may cause the airways to narrow, making it harder to breathe and potentially triggering asthma or COPD symptoms. It also makes the formoterol in the Trimbow inhaler less effective at opening your airways.
