In turn, enhancing KCC2 activity not only potentiated L838,417-induced analgesia, it rescued its analgesic potential at high doses, revealing a novel strategy for analgesia in pathological pain, by combined targeting of the appropriate GABA A R-subtypes and restoring Cl - homeostasis
When to increase dose Consider increasing if: Minimal response after 4-6 weeks at current dose No side effects at current dose Current dose below the higher end of recommended range Goals not being met with conservative approach Increase gradually, typically by 25-50% at a time
