Fludiazepam is a benzodiazepine derivative with anxiolytic and sedative properties, structurally related to diazepam. It was previously used in some countries for the short-term treatment of anxiety disorders and related conditions, but is not widely approved or marketed today due to limited safety and efficacy data.
Pharmacokinetics
Pharmacokinetic parameters are estimated based on structural similarity to diazepam and available benzodiazepine data. No primary literature sources reporting PK for fludiazepam in humans were identified. Estimates below are for a healthy adult following oral administration.
