Pharmacological action
Pharmaceutical group:
slow calcium channel blocker.
Pharmaceutical action:
Selective BMCC, reduces Ca2 + entry into cells and reduces their concentration in the plasma depot, reduces smooth muscle tone of arterioles, enhances the vasodilating effect of carbon dioxide.
Directly affecting the smooth muscles of blood vessels, reduces their response to nutrients (adrenaline, norepinephrine, dopamine, angiotensin, vasopressin). It has a vasodilating effect (especially in relation to cerebral vessels), without having a significant effect on blood pressure.
It exhibits moderate antihistamine activity, reduces the excitability of the vestibular apparatus, lowers the tone of the sympathetic nervous system.
Effective in patients with latent cerebrovascular insufficiency, initial atherosclerosis of the cerebral vessels and chronic diseases of the cerebral vessels with post-stroke focal symptoms.
In patients with impaired peripheral circulation, improves blood supply to organs and tissues (including the myocardium), enhances postischemic vasodilation.
Increases the elasticity of erythrocyte membranes, their ability to deform, reduces blood viscosity. Increases muscle resistance to hypoxia.
Pharmacokinetics:
TCmax after oral administration – 1-3 hours, communication with plasma proteins – 91%.
Completely metabolized in the liver (via dealkylation). T1 / 2 – 4 hours.
It is excreted in the form of metabolites: 1/3 – the kidneys and 2/3 – with feces.
Indications
Chronic cerebrovascular insufficiency (dizziness, tinnitus, headache, memory impairment, decreased attention span).

Prevention of kinetosis (road sickness – sea and air sickness).

Disturbances of peripheral circulation (intermittent claudication, Raynaud’s disease, diabetic angiopathy, thrombophlebitis, trophic disorders, including trophic and varicose ulcers).
Special instructions
Due to the antihistamine effect, cinnarizine can affect the result of anti-doping control of athletes (false-positive result), as well as neutralize positive reactions during skin diagnostic tests (treatment should be canceled 4 days before the study).
With prolonged use, a follow-up examination of liver, kidney and peripheral blood picture is recommended.
Breastfeeding is not recommended for women taking cinnarizine.
Patients with Parkinson’s disease should be prescribed only in those cases where the benefits of its appointment exceed the possible risk of worsening.
