The invention provides a muscular amino acids and nucleosides injection medicinal composition and discloses a preparation method of the medicinal composition. The medicinal composition is prepared from a muscular amino acids and nucleosides injection, pentoxifylline, fructose diphosphate sodium and polyethylene glycol. When the medicinal composition is applied in vitro, the liver homogenate breathing activity of a guinea pig can be increased, an activity stimulation index of breathing activity determined by using a Warburgs respirometer is about 4.2, which is far higher than the stimulation index of the liver homogenate breathing activity of the guinea pig during separate testing by using muscular amino acids and nucleosides, the pentoxifyllinum and the fructose diphosphate sodium, and thus, the treating effect on heart cerebrovascular disease is enhanced greatly.

Provided are a preparation method for a solution containing fructose sodium diphosphate, use thereof, and a preparation method for a fructose sodium diphosphate injection. The preparation method for the solution containing fructose sodium diphosphate comprises performing solid-liquid separation on a yeast reaction solution containing fructose sodium diphosphate, anion exchange resin extraction, decolorization, reverse osmosis treatment and sterilization treatment. The yeast reaction solution is obtained by contacting a sugar-containing material containing glucose and phosphoric acid with yeast. Other dosage forms such as fructose sodium diphosphate injections or fructose sodium diphosphate oral solutions can be further prepared using said method. The preparation method has advantages of greatly reducing the dosage of an organic solvent and reducing the production cost.
