An early response followed by another medicine cannot establish comparative superiority.
A young man with schizoaffective disorder and catatonia received oral clonazepam because injectable lorazepam was not immediately available. His Bush–Francis score fell from twenty-three to eight within two hours. Lorazepam was given later, and antipsychotic treatment was restarted. Short follow-up described continued improvement.
Treatment order, route, timing and carryover prevent a fair clonazepam-versus-lorazepam efficacy comparison. The initial response was substantial but incomplete. One patient’s course cannot establish optimal dosing, maintenance strategy or recurrence risk.
For reviewing a challenge response, preserve the rating scale, elapsed time and every subsequent intervention. An additional drug producing little immediate score change does not prove it is inferior when the first drug is still active. The case documents a possible alternative response while leaving comparative effectiveness unresolved.
