Oxazepam

Benzodiazepineprescriptionoral · inferred

Short-acting 3-hydroxy benzodiazepine. Both a clinical drug (Serax) AND the terminal active metabolite of the diazepam/clorazepate/chlordiazepoxide cascade. Primarily glucuronidated (no CYP) → safe in hepatic impairment.

Projected serum levels — 15 mg, twice daily

Oxazepam
Oxazepam modeled serum levels, 15 mg twice daily over 15 days Population-based pharmacokinetic estimate. Steady state reached after approximately 2 days. 0 5 10 15 20 Day 0 Day 4 Day 7 Day 11 Day 15 Time on a regular schedule ≈ steady state · day 2
Oxazepam modeled serum levels with a loading dose of 24.1 mg, then 15 mg twice daily The first dose is larger so levels approach steady state faster. 0 5 10 15 20 Day 0 Day 4 Day 7 Day 11 Day 15 Time on a regular schedule

Maintenance schedule: 15 mg twice daily (oral).

Loading schedule: 24.1 mg on day 1, then 15 mg twice daily — reaching therapeutic levels sooner.

Modeled steady state after ~2 days: peak ≈ 18.1 mg, trough ≈ 8.2 mg body load. Population-based estimate over 15 days for a 15 mg dose at a 70 kg reference body mass — the interactive app scales curves to your doses, timing, and body mass.
