About this study

The FORTITUDE trial will provide head-to-head evidence on the benefits and harms of two commonly prescribed neuromodulators (low-dose morphine and pregabalin), the effectiveness of a virtual cough control therapy, exploratory assessment of potential synergy in combining these interventions, and the long-term outcomes of these treatments in patients with refractory or unexplained chronic cough.
