Fabomotizole

Other anxiolytics (local classification)

ATC code: N05BX-AFOBAZOLE (Fabomotizole (local code))

Mechanism of action

The manufacturer claims selective anxiolytic action without sedation or muscle relaxation via sigma-1 receptor interaction. The molecule is registered only in Russia and a few CIS countries. Fabomotizole has not been studied in PubMed-indexed RCTs with adequate methodology. International anxiety disorder guidelines ( 2023, CG113) do not include the drug.

Indications

F

Generalized anxiety disorder

Not recommended

International GAD guidelines ( 2023, CG113, WFSBP 2023) list SSRIs (escitalopram, sertraline, paroxetine) and SNRIs (venlafaxine, duloxetine) as first-line therapy. Fabomotizole is not mentioned. The drug is not registered outside Russia.

F

Insomnia

Not recommended

Afobazole has no evidence base for sleep disorders. International insomnia guidelines ( 2021, CG193) recommend cognitive behavioural therapy (CBT-I) as first-line and, if needed, melatonin agonists or orexin antagonists. Fabomotizole is not mentioned in these documents.

F

Premenstrual syndrome

Not recommended

For PMS, 2023 and international guidelines recommend CBT, selective serotonin reuptake inhibitors (sertraline, fluoxetine, citalopram) for marked symptoms, and combined oral contraceptives. Afobazole is not included.

F

Stress and adjustment (marketed indication)

Not recommended

'Stress', 'adjustment disorder', and 'nervous tension' are loose marketing categories. For subclinical anxiety, international guidelines recommend psychotherapy (CBT), stress-management techniques, and physical activity rather than prescription or over-the-counter 'calming' drugs.

Practical notes

Russian practice note

Afobazole is sold over-the-counter in Russia and promoted in TV advertising as a safe alternative to benzodiazepines. The drug is registered only in CIS countries. The international pharmaceutical industry has not replicated the molecule: no RCTs in PubMed, no or submissions.

Common myths

Myth: 'Afobazole does not cause dependence, so it is safer than benzodiazepines'. Fact: for a drug with unproven efficacy, 'no side effects' often means 'neither effect nor data'. Benzodiazepines cause dependence because they genuinely act on GABA receptors. The safety of an alternative must be evaluated against demonstrated benefit, not a marketing claim.
