Morphine Sulphate clinical trials

A 2x2 Factorial, Randomized, Open-label Trial to Evaluate Neuromodulators and Cough Control Therapy in Patients With Refractory or Unexplained Chronic Cough

This study looks at new ways to help people with long-lasting coughs that haven't responded to usual treatments. It tests two medicines (low-dose morphine and pregabalin) and a special cough therapy, separately and together, to see which works best and is safest.
