Almitrine dimesylate price
Product name:Almitrine dimesylate
CAS: 29608-49-9
Molecular Formula: C28H37F2N7O6S2
Molecular Weight: 669.76
Product description:This article mainly through Amy triazine play its pharmacological effects. Amy triazine role in carotid chemoreceptor, excited to breathe, to strengthen alveolar capillary gas exchange, increase in arterial oxygen partial pressure and oxygen saturation. Raubasine improve cerebrovascular insufficiency of mitochondrial respiratory control neurons in the brain, enhance the effect of Amy triazine strength and maintain time. Both share, can make the cerebral cortex increased oxygen partial pressure, increase the brain tissue oxygen content, improve the brain tissue of extraction and utilization of glucose, restore the aerobic metabolism, increase the cell's energy supply, so that the brain function improved and strengthened. Mainly used for subacute and chronic cerebrovascular dysfunction, sequela of cerebral ischemia, psychiatry, behavior disorders, and chronic obstructive pulmonary disease.
