What is a PBR drug?

A PBR drug refers to a pharmacological agent that targets the Peripheral Benzodiazepine Receptor (PBR), which is distinct from the Central Benzodiazepine Receptor (CBR). PBR drugs are being investigated for their potential role in modulating various biological processes, including chloride ion dynamics and mitochondrial function, which are implicated in conditions like myocardial injury.
