High Risk: Synergistic respiratory depression and aspiration risk
Benzodiazepines and alcohol both enhance GABAergic signalling at the GABA-A receptor, though at different binding sites. The resulting more-than-additive depression can cause severe sedation, impaired coordination, memory disturbance, loss of consciousness, respiratory depression and a risk of aspiration. This combination is among the most common causes of substance-related emergency admissions worldwide.

Both substances bind to the following receptors, increasing the risk of pharmacological interactions.
