Bioactivity Comments
Due to the complex and varied nature of the precise subunit composition of GABAA receptors, and a paucity of affinity data with definitive molecular details, we have not tagged a primary target for this drug. In March 2016 lorazepam was reported as a GPR68 positive allosteric modulator for the agonist proton for cAMP production.
