Product name:Metroprolol succinate
CAS: 98418-47-4
Molecular Formula: 2C15H25NO3.C4H6O4
Molecular Weight: 652.82
Product description:Widely used for high blood pressure, coronary heart disease, chronic heart failure and arrhythmia treatment of selective beta 1 receptor blockers for metoprolol tartaric acid metoprolol ordinary tablets, its elimination half-life is shorter, about 3 ~ 4 hours, so the plasma drug concentration fluctuation is bigger, and medicine need to 2 ~ 4 times a day. In order to overcome these shortcomings, astrazeneca company recently launched succinate metoprolol zyban is a kind of brand-new metoprolol long-term preparation, medicine only 1 times a day, 24 hours can ensure constant metoprolol blood drug concentration and beta 1 receptor blockade effect, on the pharmacology and clinical therapeutics has many advantages.

What is Levocarnitine
Product name:Levocarnitine
CAS: 541-15-1
Molecular Formula: C7H15NO3
Molecular Weight: 161.2
Product description:Mammals in energy metabolism of natural substances in the body, its main function is to promote the lipid metabolism. In hypoxia and ischemia, fatty acyl - CoA accumulation, mitochondria and accumulate, long chain fatty acyl carney dean free carney dean for consumption and reduce a lot. Ischemia hypoxia in ATP levels drop, the cell membrane and the cell membrane permeability increased, accumulation of lipid acyl CoA can cause membrane structure change, membrane disruption and lead to cell death. In addition, when oxygen is given priority to with anaerobic glycolysis sugar, fatty acids, such as the buildup acidosis, ion is disorder, autolyzed cell death. Enough free carney dean can make the accumulation of fatty acyl - CoA into mitochondria, reduce its of adenine nucleotide transposition enzyme inhibition, to run oxidative phosphorylation.
