Pharmacodynamics and pharmacokinetics
Reduces the flow of calcium into the cell, reduces the level of calcium in the plasmalemma depot, enhances the vasodilatory effect of carbon dioxide, reduces the tone of smooth muscle tissue of arterioles. Cinnarizine has a vasodilating effect and does not affect blood pressure.
The antihistamine activity of the drug is moderate, reduces the tone of the sympathetic nervous system, and moderately reduces the excitability of the vestibular apparatus.
Cinnarizine is effective in patients with a latent variant of cerebral circulatory insufficiency, with the initial form cerebral atherosclerosis a stroke . In persons with impaired peripheral circulation, it improves the nutrition of tissues, organs, myocardium, and increases post-ischemic dilation of the lumen of blood vessels. Cinnarizine reduces blood viscosity, moderately increases the ability of red blood cells to deform, and has a positive effect on the elasticity of their membranes.
Maximum absorption occurs within 1-3 hours. It is excreted in the form of metabolites in the urine by one third and in feces by two thirds. The half-life is 4-24 hours.

pharmachologic effect
Cinnarizine is a drug from a group of drugs called calcium channel blockers. It helps improve microcirculation. Suppresses nystagmus (uncontrolled eye movements) and other manifestations of vestibular disorders. Has an antihistamine (antiallergic) effect.
Indications for use
Symptomatic treatment of mild and moderately severe dementia for the correction of cognitive and behavioral disorders. Note: before starting treatment, you must make sure that these symptoms are not a manifestation of another disease (for example, a therapeutic, psychiatric or neurological profile) and do not require special treatment.
Use during pregnancy and lactation
Symptomatic treatment of vestibular disorders (Meniere's syndrome of labyrinthine origin, including dizziness, nausea, vomiting, tinnitus, nystagmus). Prevention of kinetosis (sickness when moving). Symptomatic therapy for peripheral circulatory disorders (intermittent claudication syndrome) in adults.
Precautionary measures
Cinnarizine (like other antihistamines) may cause stomach discomfort. Taking the medicine after meals can reduce irritation of the gastric mucosa. Since cinnarizine may cause drowsiness, extreme caution should be used in combination with drugs that have a depressant effect on the central nervous system. In patients with Parkinson's disease, cinnarizine can be prescribed only if the benefits of therapy outweigh the possible risk of worsening the disease. It is necessary to prescribe the drug with caution to patients over 65 years of age, children, as well as patients with a family history or clinical symptoms of extrapyramidal disorders. Cinnarizine should be used with caution in patients with hepatic or renal impairment. In persons prone to hypotension, blood pressure should be monitored during treatment. Due to the presence of an antihistamine effect, cinnarizine can affect the results of anti-doping control of athletes (false-positive results), as well as neutralize positive reactions during skin diagnostic tests (treatment should be discontinued 4 days before the test). Due to the lactose content, the drug should not be prescribed to patients with galactose intolerance, lactase deficiency or glucose-galactose malabsorption. If symptoms persist or worsen while taking the drug, you should consult a doctor. Children. The drug is contraindicated for use in children under 5 years of age due to the lack of sufficient data.
Interaction with other drugs
Concomitant use of alcohol and the use of CNS depressants or tricyclic antidepressants may enhance the sedative effect of any of the listed drugs or Cinnarizine-NAN. Due to the presence of an antihistamine effect, cinnarizine can neutralize positive reactions during skin diagnostic tests (treatment should be discontinued 4 days before the test). If you are taking other medications at the same time, you should consult your doctor.

It dilates small arteries and improves blood flow in peripheral tissues (arms, legs, fingers, etc.) and the brain. Cinnarizine is used for the treatment and prevention of various disorders of cerebral circulation (for example, hypertension with encephalopathy, cerebral atherosclerosis, dementia of vascular origin, after a stroke, traumatic brain injury, etc.) and peripheral circulation (for example, trophic ulcers, numbness in the extremities, obliterating endarteritis, diabetic angiopathy, etc.), as well as kinetosis (motion sickness, etc.). Indications for use: Indications for use of the drug Cinnarizine-NAN are: - Maintenance therapy for symptoms of labyrinthine disorders, which include fainting, tinnitus, nystagmus, nausea and vomiting. — Prevention of motion sickness. — Prevention of migraine. - Maintenance therapy for symptoms of cerebrovascular origin, which include syncope, tinnitus, headache of vascular origin, irritability, memory loss and inability to concentrate. - Maintenance therapy for symptoms of peripheral vascular disorders, which include Raynaud's disease, acrocyanosis, intermittent claudication, trophic disorders, trophic and varicose ulcers, paresthesia, night spasms of the extremities, cold extremities.
Method of administration: For the prevention of sea and air sickness in adults - 25 mg of Cinnarizine-NAN - 1 hour before the upcoming trip, if necessary, repeat the dose in the same dose every 6 hours.
