How could benzodiazepines like diazepam work to counteract the effect of tetanus toxin?

Benzodiazepines like diazepam may help counteract the effects of tetanus toxin by enhancing the inhibitory neurotransmitter activity in the central nervous system. Tetanus toxin interferes with neurotransmission, leading to sustained muscle contractions and spasms. By potentiating the effects of gamma-aminobutyric acid (GABA), benzodiazepines can promote muscle relaxation and reduce the severity of spasms associated with tetanus. However, they do not directly neutralize the toxin itself but can alleviate some of its clinical effects.
