Used for the short-term treatment of anxiety disorders.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Fludiazepam is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. Fludiazepam accumulates primarily in the cortex and thalamus.


5.2 MeSH Pharmacological Classification

Anticonvulsants

Drugs used to prevent SEIZURES or reduce their severity. (See all compounds classified as Anticonvulsants.)


Muscle Relaxants, Central

A heterogeneous group of drugs used to produce muscle relaxation, excepting the neuromuscular blocking agents. They have their primary clinical and therapeutic uses in the treatment of muscle spasm and immobility associated with strains, sprains, and injuries of the back and, to a lesser degree, injuries to the neck. They have been used also for the treatment of a variety of clinical conditions that have in common only the presence of skeletal muscle hyperactivity, for example, the muscle spasms that can occur in MULTIPLE SCLEROSIS. (From Smith and Reynard, Textbook of Pharmacology, 1991, p358) (See all compounds classified as Muscle Relaxants, Central.)


Anti-Anxiety Agents

Agents that alleviate ANXIETY, tension, and ANXIETY DISORDERS, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. ADRENERGIC BETA-ANTAGONISTS are commonly used in the symptomatic treatment of anxiety but are not included here. (See all compounds classified as Anti-Anxiety Agents.)


5.3 ATC Code

N - Nervous system

N05 - Psycholeptics

N05B - Anxiolytics

N05BA - Benzodiazepine derivatives

N05BA17 - Fludiazepam


5.4 Metabolism/Metabolites

Hepatic.


5.5 Mechanism of Action

Fludiazepam has similar action to diazepam, but binds with four times more affinity to benzodiazepine receptors than diazepam.
