Requirement 1: a method of preparing a drug preparation for injection, A method characterized by the addition of a solution of sodium chloride from about 25 mm to 150 mm to a drug formulation results in a formulation ready for injection, In this case, the prepared formula is almost the isotopes of the plasma, or the slightly lower or slightly higher isotopes of the plasma,In this case, the prepared formula has enough ionic force to prevent mangrove population. 19. Claim 22: a method complying with claims 1 to 21, characterized in that prior to the addition of a sodium chloride solution, the drug formulation comprises histidine, glicina, sucrose, polyphosphate and nine factors. 1. A container containing liofilizada cake. If liofilizada cake is recombined in 5ml water, its solution will include: (I) histidine from about 5mm to about 30mm；(II) glycerin from about 0.1 M to about 0.3 m； (III) sugar from about 0.5% to 2%； (IV) polyurethane from about 0.001% to about 0.05%； (V) factor IX from about 50 ml to about 2000 ml / ml； (b) a 25 mm to 150 mM solution of sodium chloride； and (c) instructions for reconstituting liofilizada cakes with a solution of sodium chloride；Therefore, after recombination, the resulting solution is almost isotopic and has enough ionic force to prevent the addition of erythroprotein in intravenous injection. Claim 33: a lymphoid muffin, characterized in that if the lymphoid muffin is recombined in 5 ml of water, the solution will include: (I) histidine from about 5 mm to about 30 mm； (II) glycerin from about 0.1 M to about 0.3 m； (III) about 0.5% to 2% sugar； (IV) about 0.001% to 0.05% polyurethane；From about 50 ml / ml to about 2000 ml / ml factor IX.Reivindicación 1: Un método para la preparación de una formulación farmacéutica para inyección intravenosa, el método caracterizado porque comprende la adición de alrededor de 25 mM hasta alrededor de 150 mM de solución de cloruro de sodio a la formulación farmacéutica resultando de esa manera en una
