Medications include antacids, which neutralise acidity of gastric secretions, and proton pump inhibitors, as well as H2 receptor blockers, which decrease hydrochloric acid production in the first place.

药物包括能中和胃酸的抗酸药、质子泵抑制，以及H2受拮抗，它们首先会减少盐酸的产。

To address this potential problem, scientists developed NMDA receptor antagonist called Memantine, which works by blocking NMDA receptors and thus limiting calcium influx into the neuron.
