Sinzine Sr
Sinzine Sr Uses, Dosage, Side Effects, Food Interaction and all others data.
Sinzine Sr provides quick relief of various symptoms of cerebral and peripheral circulation disorders. Sinzine Sr protects attacks of vascular headache such as migraine. Sinzine Sr normalizes cerebral circulation time and improves cerebral irrigation in patients suffering from the disorders of cerebral circulation. Sinzine Sr normalizes arterial pulsations in patients suffering from vasospastic disorders. Sinzine Sr 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.
Sinzine Sr 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.
Sinzine Sr 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 Sinzine Sr also block muscarinic acetylcholine receptors and are used as anti-emetic agents. Sinzine Sr through its calcium channel blocking ability also inhibits stimulation of the vestibular system.

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.
Sinzine Sr 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 Sinzine Sr works
Sinzine Sr inhibits contractions of vascular smooth muscle cells by blocking L-type and T-type voltage gated calcium channels. Sinzine Sr has also been implicated in binding to dopamine D2 receptors, histamine H1 receptors, and muscarinic acetylcholine receptors.
