Is diazepam or lorazepam the most effective benzodiazepine for use in paramedic management of convulsive seizures in adults?

Diazepam, a drug from the benzodiazepine family, has been used for the acute management of status epilepticus outside of hospital since its introduction in 1963 (Roche, 2007). Although known to be an effective treatment for the termination and subsequent prophylaxis of seizures (Dreifuss et al, 1998), there have been a number of developments in benzodiazepine production since its emergence, leading to the discovery of alternative agents.
