Effects of apremilast (20 mg/kg), apremilast (20 mg/kg) + PKA inhibitor H-89 (10 mg/kg), or a β1-specific antagonist salicylidene salicylhydrazide (SCS, 40 mg/kg) on ethanol- and GABAergic-mediated behaviors are summarized as follows: = no change from saline control; ↑ (increased) or ↓ (decreased) response from saline control; → (longer) or ← (shorter) recovery from rotarod ataxia compared with saline control. GABAergic drugs have subunit-specific or non-specific actions depending on the dose. Etomidate mediates ataxia mainly through β2-containing receptors.
