piracetam + cinnarizine: what international guidelines say – evidence review – Evigrade
piracetam + cinnarizine
Combination nootropic (local classification)
ATC code: N06BX-FEZAM(Fezam (piracetam + cinnarizine, combination local code))
Mechanism of action
A combination of 400 mg piracetam (a cyclic GABA derivative with unclear nootropic mechanism) and 25 mg cinnarizine (an H1-antagonist-class calcium channel blocker with vestibular blocking properties). The manufacturer claims combined nootropic and 'vasoactive' effects. The piracetam-cinnarizine combination originated in the USSR and is not registered outside CIS countries. Individual components – piracetam and cinnarizine – are also absent from current international neurology guidelines.
Indications
F
Cognitive impairment
Not recommended
For cognitive impairment, international guidelines ( NG97, 2018) list cholinesterase inhibitors and memantine for Alzheimer dementia and workup for reversible causes in mild cognitive impairment. Combination nootropics with piracetam are not included.
F
Stress, anxiety, memory, and behavior
Not recommended
— Subjective age-related memory complaints without objective cognitive impairment:
For age-related memory complaints without objective cognitive impairment, international sources do not recommend nootropics. The reasonable approach is sleep, physical activity, cognitive training, and correction of reversible causes.
— Chronic cerebral ischaemia / dyscirculatory encephalopathy:
'Chronic cerebral ischaemia', 'dyscirculatory encephalopathy', and 'vegetative-vascular dystonia' are absent from ICD-11 and international neurology. Fezam is a piracetam-cinnarizine combination assembled under diagnoses that do not exist outside Russia. , , , and do not mention the drug or its components.
F
Tinnitus
Not recommended
-HNS 2014 and NG214 note the absence of evidence-based pharmacotherapy for tinnitus. Fezam is not in these recommendations. Russian practice of prescribing it 'for ear ringing' is not considered substantiated.
F
Vertigo
Not recommended
In Russian practice, Fezam and Omaron are popular for 'dizziness', but 2024 and Barany Society guidelines require a specific diagnosis – BPPV, Meniere's, vestibular neuritis, vestibular migraine – and condition-specific treatment. The fixed piracetam-cinnarizine combination is not in these documents. Cinnarizine in older adults, especially with prolonged use, can cause drug-induced parkinsonism.
Practical notes
Russian practice note
Fezam and Omaron are a fixed-combination product very popular in Russian neurology and general practice. They are prescribed to people over 50 complaining of dizziness, tinnitus, and memory decline. In Western medicine such complaints trigger workup for specific conditions – BPPV, depression, sleep apnoea, Meniere's disease, migraine. A universal drug for an umbrella diagnosis delays real diagnostic work.
Safety concerns
In older patients, cinnarizine can cause drug-induced parkinsonism with prolonged use. This is a known adverse effect of D2-antagonist compounds (including cinnarizine). In patients with longstanding memory complaints who take Fezam or Omaron for years, the emergence of bradykinesia and tremor should prompt discontinuation and workup for drug-induced parkinsonism.
