Bromazolam

Benzodiazepineoral · inferred

Designer triazolobenzodiazepine (8-bromo analog of alprazolam) sold in the illicit supply, typically as pressed "pills" or powder, often adulterating street opioids. Similar binding profile to alprazolam with comparable anxiolytic, hypnotic, and amnestic effects. Plasma half-life estimated ~17-18 h in limited published cases. No medical indication; scheduled or controlled in most jurisdictions. Overdose risk is amplified by co-use with opioids and ethanol.

Maintenance schedule: 1 mg as needed (shown daily) (oral).

Loading schedule: 2.7 mg on day 1, then 1 mg as needed (shown daily) — reaching therapeutic levels sooner.

Modeled steady state after ~4 days: peak ≈ 2.1 mg, trough ≈ 1.4 mg body load. Population-based estimate over 15 days for a 1 mg dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
