Pharmacology
- Indication
Used for the short-term treatment of anxiety disorders.
- Pharmacodynamics
Fludiazepam is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. Fludiazepam accumulates primarily in the cortex and thalamus.
- Mechanism of action
Fludiazepam has similar action to diazepam, but binds with four times more affinity to benzodiazepine receptors than diazepam.
