That's a great question, and one worth discussing with your doctor since everyone's experience can vary. The combination of Opsumit (macitentan) and tadalafil works through two different pathways to help reduce pressure in the pulmonary arteries.

Here's how each component works:

- Macitentan (Opsumit) blocks a substance called endothelin-1, which causes blood vessels to narrow — helping to slow disease progression
- Tadalafil relaxes the blood vessels in the lungs to improve blood flow and make it easier for the heart to pump

Generally speaking, PDE5 inhibitors like tadalafil may show some effects relatively quickly, while endothelin receptor antagonists like macitentan tend to show benefits over a longer period of consistent use.

Most clinical improvements — like better exercise ability — are typically measured over weeks to months of treatment. It's important to keep taking the medication as prescribed even if you don't feel immediate changes.

Always check in with your healthcare provider if you have concerns about whether your treatment is working, as they can monitor your progress and adjust as needed.
