Cinazin
Cinazin Uses, Dosage, Side Effects, Food Interaction and all others data.
Cinazin provides quick relief of various symptoms of cerebral and peripheral circulation disorders. Cinazin protects attacks of vascular headache such as migraine. Cinazin normalizes cerebral circulation time and improves cerebral irrigation in patients suffering from the disorders of cerebral circulation. Cinazin normalizes arterial pulsations in patients suffering from vasospastic disorders. Cinazin significantly increases the rate of inflow or pulsation and the blood flow in the most affected limb as well as the walking distance of patients suffering from intermittent claudication.
Cinazin acts as an antihistamine, labyrinthine sedative and a peripheral antivasoconstrictor. Inarzin is a selective calcium antagonist, inhibiting the influx of Ca2+ intracellularly. It prevents the Ca2+ dependent contraction of arterial smooth muscle by inhibiting Ca2+ influx through smooth muscle calcium channels and thereby, improves vestibular symptoms and prevents peripheral arterial disease.
Cinazin is an antihistamine and a calcium channel blocker. Histamines mediate a number of activities such as contraction of smooth muscle of the airways and gastrointestinal tract, vasodilatation, cardiac stimulation, secretion of gastric acid, promotion of interleukin release and chemotaxis of eosinophils and mast cells. Competitive antagonists at histamine H1 receptors may be divided into first (sedating) and second (non-sedating) generation agents. Some, such as Cinazin also block muscarinic acetylcholine receptors and are used as anti-emetic agents. Cinazin through its calcium channel blocking ability also inhibits stimulation of the vestibular system.

Uses
It is mainly used for the symptomatic treatment of nausea and vertigo due to Meniere's disease and other labyrinthine disturbances and for the prevention and treatment of motion sickness. It is also used in the management of various vascular disorders.
Cerebral circulatory disorders:
- Prophylaxis and maintenance therapy for symptoms of cerebral vascular spasms and arteriosclerosis such as dizziness, ear buzzing (tinnitus), vascular headache, unsociability and irritability, fatigue, sleep rhythm disorders such as premature awakening, involutional depressions, loss of memory and lack of concentration, incontinence and other disorders due to aging.
- Sequel of cerebral and cranial trauma.
- Post-apoplectic disorders.
- Migraine.
Peripheral circulatory disorders: Prophylaxis and maintenance therapy for symptoms of vascular spasms and arteriosclerosis (obliterating arteritis, thromboangitis obliterans, Raynaud's disease, diabetes, acrocyanosis, perrio, etc.) such as: intermittent claudication, trophic disturbances, pregangrene, trophic and varicose ulcers, paraesthesia, nocturnal cramps, cold extremities.
Disorders of balance:
- Prophylaxis and maintenance therapy for symptoms of labyrinthine arteriosclerosis, vestibular irritability, Meniere's syndrome, such as vertigo, dizziness, giddiness, syncopal attacks, tinnitus, nystagmus, nausea and vomiting.
- Prophylaxis of motion sickness.
Cinazin is also used to associated treatment for these conditions: Balance Disorders, Dizziness, Motion Sickness, Nausea, Peripheral Artery Disease (PAD), Raynaud's Phenomenon, Inadequate cerebral circulation, Peripheral vasculopathy
How Cinazin works
Cinazin inhibits contractions of vascular smooth muscle cells by blocking L-type and T-type voltage gated calcium channels. Cinazin has also been implicated in binding to dopamine D2 receptors, histamine H1 receptors, and muscarinic acetylcholine receptors.
