DBH and post-traumatic stress disorder: In this sense, our hypothesis is that sotalol (a peripheral non-selective β-ARs blocker) (Martinho et al., 2022) and nepicastat (a DBH inhibitor) (Martinho et al., 2021; Moreira-Rodrigues and Grubisha, 2022; Abumaria et al., 2023) might help to decrease PTSD occurrence by weakening abnormal traumatic memories formation and consolidation, and may support in the formation of neutral contextual memories.
